Precision diaphragm pumps: Lifesavers in medical technology (13.11.2020)

Capnometry is a medical-technical measuring method for monitoring the breathing activity of patients. Inside the analyzer, a diaphragm pump ensures reliable measurement results.

The introduction of capnometry has led to a significant reduction of complications in ventilated patients. It has therefore become indispensable in anesthesiology, intensive care units and emergency services. Measuring the CO2 content in the exhaled air of the patient ensures that no life-threatening situations arise.

With the "Side Stream" method, a small diaphragm pump inside the capnometer ensures a precise exhalation air flow. A small amount of air is constantly extracted from the patient's breathing gas. This breath sample is pumped through an infrared sensor that continuously measures the CO2 content.

Our precision pumps of the 100 and 200 EC series are predestined for pumping small sample streams. With their quiet and low-vibration operation, they can be used close to the patient.

In partnership with our customers we develop precise solutions for medical breathing gas analysis. Development at the highest technical level and production in Germany ensure excellent quality. The high reliability of our products has also convinced Corscience, one of the leading companies in medical gas analysis.

Bank on a strong and reliable partner. Please call us (Phone +49 (0)201 31697-0) or send us a product inquiry. We are glad to help.

We care.

Best equipped: new miniature pumps of the EC Series 200 (13.01.2020)

Small, precise, powerful – for many years, the miniature diaphragm pumps of the EC Series 200 have proven themselves as extremely reliable components in the most diverse fields of application. Now the next stage of development follows: with the relaunch of the EC Series 200 we are taking this success story to a new level.

In many areas of medical, laboratory and environmental technology, our eccentric diaphragm pumps of the 200 series have been in service for a number of years. With very compact dimensions and low power consumption they are predestined for mobile applications such as gas detectors, gas analysis, pipetting, fuel cells, etc. In addition to the high construction quality of these pumps, our customers particularly appreciate the large control range and high operational reliability.

But we are not resting on our laurels: with the concentrated know-how of 50 years of design experience, we have developed the EC Series 200 from scratch. The result is impressive: with even more compact dimensions, the performance of the miniature pumps has been raised to a new level.

Our new FCV technology ("fast closing valves") with fixed valves makes this performance increase possible. Valve flutter is also eliminated. Furthermore, our FCV technology reliably prevents the tiny valves from "sticking". This makes the pump insensitive to high humidity and condensate. Furthermore, the FCV technology makes the pump completely independent of specific positions.

For tubeless mounting, we offer a standardized manifold solution as well as a wide range of customizing options. This fast and safe installation method simplifies the integration of the pump into the overall system and prevents leakages.

Thus our EC Series 200 is well prepared for the new decade!

New ‘SP2’ building doubles our operating space (04.02.2019)

Just 6 years ago we dedicated our new corporate headquarter at the Essen M1 industrial park. Our ambitious goals of enhanced consulting and service quality, greater proximity to the customer and more specialized customization were reached in a short amount of time. We are not resting on our laurels, though: another new building will more than double our operating space. The ground-breaking ceremony took place on January 23.

The world's smallest vane and diaphragm pumps are produced in Essen. Schwarzer Precision was founded there in 1970 and is now one of the leading manufacturers of miniature pumps on the market. The pumps are in great demand worldwide, especially in medical technology. But our precision pumps are also used successfully around the globe in laboratory, environmental and analysis technology as well as in a wide variety of industrial applications.

"We care" - on request, our pumps can be adapted to the specifications of our customers with high precision. Thanks to an ingenious modular system, numerous variation options can be implemented quickly and cost-effectively. However, our pumps always have one thing in common: extreme durability and maximum safety for customers, users and patients.

In addition, our company philosophy “We care” stands for a high level of commitment to social projects and environmental protection, for flexible working time models and for moderate, healthy company growth. Our new construction project on the adjacent property shall create room in particular for highly specialized production technologies. Our research and development labs will also be significantly expanded once more. Components for medical and laboratory equipment can then be manufactured in a cleanroom climate with absolute purity.

A precision injection molding department will be available for the production of especially sensitive components such as valve seats, valve chambers, diaphragm frames and elastomers. Fitting tolerances and gap dimensions are reduced to an absolute minimum thanks to our own production of these parts. For our international customers, this means that even the most unusual requirements can now be implemented even faster and more precisely.

Our current company building has already been nominated for the BDA Architecture Award for its technical and design qualities. This high standard also distinguishes our new five-story “SP2” building. The dedication is planned for next year.

Manifold Mountings: perfect system integration through tubeless pump installation (16.11.2018)

Schwarzer Precision is the specialist for application-specific optimized miniature pumps. Our new “Manifold-Mountings” are the perfect solution to integrating our pumps without tubes and space-saving into your system. The advantages are obvious.

As small as our precision pumps may be, sometimes there is simply not enough space for conventional tubing. Here “Manifold Mountings” are the ideal solution: the direct, tubeless connection of our gas and liquid pumps to your system block. This enables a highly integrated structure of the entire system, including all control technology, valves, sensors, etc.

This individually configurable mounting system not only saves space, but also offers other significant advantages. By consistently dispensing with tubing and hose olives, the number of necessary seals is reduced. At the same time, the conveying medium has less contact with foreign materials. This increases both the tightness of the overall system and the freedom from falsification of your measurements. Additional bonus: a tidy installation space makes maintenance work on the entire system easier and more cost-effective.

The Manifold Mountings can be adapted exactly to your requirements - just like our miniature pumps. We offer you individual solutions: from nozzle sealing with integrated O-rings to nozzleless connection with flat gaskets and rubber manifolds that can completely dispense with gaskets.

Why compromise then? Just contact us! We develop the perfect solution for you for the highly integrated system incorporation of our pumps. Cost-efficient, quick and reliable. We care.

600 EC-L: Fluid pumps with new valve and diaphragm technology (06.08.2018)

Our reliable fluid diaphragm pumps of the 600-L series prove themselves every day in demanding applications in medical and analytical technology. No matter how complex your requirements: we build the exactly fitting fluid pump for you! To this end, we have expanded our modular system with new valve and diaphragm technologies.

The reliable delivery of problematic media places high demands on the components of a fluid pump. The diaphragms must seal the pump chamber securely and should not become contaminated. Even when the pump is switched off, the valves must exhibit high non-return leakproofness and must not show any tendency to “stick” even at low volume flow rates.

All these objectives are met by our new valve technology with preloaded and connected valves. The trochoidal suspension causes minimum torsional movement of the valve during the stroke process. This minimizes sticking effects. The fixed connection enables precisely controlled valve movement and reliable closing even at low volume flow rates. Positive accompanying effect: with our new valve technology, even higher suction heights can be achieved.

The diaphragms of the 600 series liquid pumps are now available with a new connecting rod links. The diaphragms are no longer screwed down from above, but attached from below. In this way we achieve a completely closed membrane surface. This reduces both the susceptibility of the diaphragm to contamination and the number of components required. And here, too, the positive accompanying effect of an increase in performance is apparent.

All fluid pumps can be adapted exactly to your specifications and requirements. Our complete modular system allows a large variety of possible combinations. Your advantage: You receive the uncompromisingly suitable pump in the shortest time - without additional development costs!

Schwarzer Precision supports the "lernHÄUSER" Essen (14.06.2018)

Children are our future. For 50 years, the German children charity “Deutsche Kinderschutzbund e.V.” promotes a child-friendly society: equal education and opportunities, social safety, care and non-violence. We gladly support this important commitment!

The "Deutscher Kinderschutzbund" ("German child protection association") is the point of contact for all problems and family crises involving children, adolescents and their parents. Over 500 children take advantage each year of the offering of the Essen Child Protection Centre. The therapeutically trained staff provide counsel and support with child raising issues, separation and domestic violence situations and with various educational projects.

Almost 10% of the young people from the structurally weak north of Essen leave school without diploma. The "lernHÄUSER" ("learning homes") of the friend's association "Förderverein Kinderschutzhaus" (child protection home) offer comprehensive advancement to these students while strengthening the social and subject competency. New opportunities are thus created for the future of children from socially disadvantaged families often without access to proper education.

The high commitment of the child protection organisation is hardly conceivable without financial support. We are therefore glad to contribute: we want to permanently support the important work of the learning homes from Essen with our donations. After all, good education is the basic foundation for the future of our children.

Small, powerful, reliable: new fluid pumps for mobile applications (19.04.2018)

The powerful miniature fluid pumps from Schwarzer Precision are known worldwide for their maximum reliability. They stand the test every day in demanding applications of medical and analytical technology. But we do not rest on these laurels: a complete revision raises our smallest fluid pumps to a new level of performance!

Mobile applications require extremely compact miniature pumps. The housings of the new SP 270 EC-L series have a dimension of only 13 mm width and 26.1 mm height. The overall height was thus reduced by another 4%.

Performance data was increased at the same time: flow-optimized fluid geometries avoid micro-turbulences in dead spaces, permanently connected and preloaded valves facilitate higher pressures at maximum operating reliability. Even chemically aggressive applications do not represent a problem for our miniature pumps.

Our fluid pumps of the 270 EC-L series are maintenance-free, self-priming and safe against running dry. Nominal voltages of 3, 6 or 12 Volt as well as stable performance data in any installation position predestine our miniature pumps for mobile applications with battery or rechargeable batteries, independent of line supply.

In addition, the powerful precision pumps can be adapted exactly to your specifications and requirements. Our complete modular system allows for diverse combination options. Your advantage: You will receive just the right pump, without compromise, and without additional engineering costs!

Absolutely advanced water analysis (14.03.2018)

"C.L.A.M."® breaks records in water analysis: the small sampling device is able to detect the most minute pollutant traces up to one hundred times more accurately than conventional systems. A miniature fluid pump from Schwarzer Precision ensures highly accurate metering of the test medium.

Common water analyses use samples with a volume of one liter. "C.L.A.M." (Continuous Low-Level Aquatic Monitoring) works differently: the floating sampling system presses the test medium with low volume flow rate (5 - 60 ml/min) through an extraction filter. The pollutants from a total of 100 liters of water are thereby added up over a period of 48 hours.

Measuring only 12.5 cm in diameter and weighing less than 500 grams "C.L.A.M." is not only used in lakes and rivers but also in urban drinking water systems, wells or rain water reservoirs. The submersible system is able to take samples both at the surface of the water and in depths down to 30 meters.

The high-precision fluid diaphragm SP 270 EC-DB-L operates inside the small polycarbonate sphere. Thanks to its low current consumption, the use of a particularly small Li-Ion battery is possible. With its ball-bearing supported motor drive and exact control features, the pump ensures precise flow control. The impressive result: "C.L.A.M." reduces the pollutant detection limit in the lab by a factor of 100!

SP Precision Pumps for Robotics (15.02.2018)

"LogiRob" is a complex system of interacting picking & packing robots developed by the "Research Group Service Robotics" at the technical university FH Ulm in Germany. Precision pumps from Schwarzer Precision are employed for the sophisticated control of the robot’s gripper arm.

The two service robots that can carry out intelligent picking & packing processes at a warehouse management system completely autonomously are called "Larry" and "Robotino 3".

The pair of robots splits the complex task of identifying ordered products at the storage location, removing them from different bins and shelf systems and then navigating them on "Small Load Carriers" precisely to their destination between them. The system utilizes several recognition components and knowledge databases to unambiguously recognize the different products in any warehouse infrastructure and to transport them via different routes without collision.

A special challenge consists of the task of always grabbing the different products reliably and without damage, regardless of their shape, weight, size or storage location. "Larry" uses a high-precision pneumatic gripper arm for this operation. The exactly metered vacuum is provided by a dual-head SP precision pump. Providing high vacuum output at low current consumption and compact dimensions, the SP 628 EC-DU-VD (24 VDC) fulfills this special robotics task autonomously and extremely reliably.

Quality Lead through Innovative 3D Technology (28.09.2017)

Whether Rapid Prototyping in the Engineering Lab, Computer-assisted Measuring Processes in the Test Chamber or Non-contacting Quality Inspection at Goods Receipt: Schwarzer Precision is always up to date regarding technical developments when employing 3D systems.

We have been engineering perfect precision pumps for over 40 years, based on bundled know-how, technical enthusiasm and a keen sense for innovation. Our engineers design the virtual ideal of physically feasible solutions in 3D CAD. Each pump leaving our production department must be measured against this predefined ideal. After all, perfection in practical application requires meticulous control of each individual production step.

Our 3D profilometer with its three telecentric lens attachments allows for non-contacting measurement of complex components. Not only the outer dimensions are measured here with microscopic exactness but also the cross-sectional profiles, height differences and roughnesses of the test objects. The results are documented in a detailed test log. This guarantees highly precise comparability of CAD and measuring data.

We employ this optical 3D measuring system also at Goods Receipt. It enables us to detect minute production tolerances that could not be detected with conventional inspection methods. As a result, only components with perfect quality enter our Production.

The SP Prototype Lab is the dream of any developer: our fully equipped CAD/CAM Prototyping now also makes different 3D printing technologies available. Only a few minutes now lie between the virtual idea of the design engineer and the concrete prototype. This lets us realize technical innovations especially quickly testing them thoroughly on sample pumps. Your individual preferences are implemented in next to no time. Only proven and tested solutions enter our Production.

As SP customer you will enjoy a threefold benefit: direct communication channels, rapid prototyping and flexible integration of special requests allow us to supply you with the ideal pump for your application in the shortest possible time.


In-house injection molding for custom micro pumps (10.08.2017)

"Customizing" is one of the key assets of Schwarzer Precision. We realize any of your customer requirements on our micro pumps specifically for your needs. To ensure consistent top quality, we now also produce complex micro injection-molded parts at our own facilities. After all, only the sum of exactly matched components guarantees reliable and durable precision pumps.

Manufacturing precision injection-molded parts requires extensive know-how. By deliberately doing without external suppliers, we maintain full control of the entire production process: from proper drying of the base granulate to the exact adjustment of all injection parameters. The result: custom injection-molded parts with consistent top quality.

On our hi-tech injection molding machines we process high-performance polymers such as PPS, PEEK as well as highly reinforced polyamides, filled up to 65% with glass or carbon fibers. The special plastics, processed at a mass temperature from 330 °C to 420 °C, require enormous injection pressures, in part over 2000 bar. This allows us realizing precision parts from a weight of 0.03 grams with cross-sections smaller than 0.05 square mm. Additional tribological optimization reduces friction and wear of our injection-molded parts to an absolute minimum.

As SP customer, you benefit even twice of our in-house injection molding: short communication routes and exact control of the entire production process lets us implement your specific requirements even more specifically and faster – even for small custom series!


Vibration-reducing quick assembly for SP miniature pumps (30.03.2016)

The new assembly rings for our miniature pumps accomplish a twofold objective in one: they reduce the assembly and service times and ensure effective vibration reduction of the pump at the same time.

Device enclosure and chassis often act as resonance body due to the physics involved. Mechanical vibration is reinforced. Our vibration-reducing assembly rings prevent the transfer of vibration and structure-borne sound of the pump to the installation housings thereby ensuring especially quiet devices and measuring instruments.

The circular suspensions are simply pulled over the motor. This facilitates the installation of the pump in your application in a matter of seconds and without tools. For example, the pumps can also be mounted directly on the printed circuit board of your control electronics. The variable installation with any desired output direction of the connecting pieces is thereby fully preserved.

The vibration-reducing assembly rings are immediately available for all diaphragm pumps of the series EC 100 and EC 200 as well as for the vane pumps of the FZ series.


Customizing without compromises: modular fluid pumps (27.10.2015)

Whether in demanding medical technology, sensitive utilization in the lab or in professional printers: Fluid pumps from Schwarzer Precision are the first choice for all areas of application requiring high-precision metering with exact regulating capability. Our self-priming precision pumps convince by a minimum of pulsation and maximum reliability – even with the delivery of complex gas-fluid mixes, aggressive media or solvent-containing inks.

We are introducing the modular eccentric diaphragm pumps of the EC-L 500 series at the Medica Compamed. All parameters of these new models can be customized exactly to your individual requirements. The pump heads are manufactured from highly resistant PPS. A wide variety of materials is available among the elastomers (EPDM, FKM, FFKM, silicon, PTFE, etc.) - depending on the intended purpose. You also have a choice when it comes to the motors: from the economically prized standard drive to extremely long-lasting brushless motors and on to stepping motors with high-precision metering function. In addition, we realize diverse special requests and preferences, for example, alternative manifold solutions, external pulsation dampers for troublefree interaction with highly sensitive pressure sensors, extra large ball bearings for particularly high pressures, etc.

Our modular customizing opens up nearly unlimited options to you. Why then still compromise? Send us your specific requirements, we deliver the exactly matching product! And this at a price that will surprise you just as much as the short sample evaluation period. We look forward to your visit!

Precision pumps for inkjet printing technology (30.03.2015)

Whether large format or label printer: professional inkjet technology requires all technical components to work perfectly in concert to achieve perfect printing results. Miniature pumps take on a variety of tasks to make this possible. Our durable and reliable eccenter diaphragm pumps of the model series 570 EC (-L/-LD) and 620 EC (-L) ensure maintenance-free continuous operation in tough everyday printing tasks.

A wide variety of miniature pumps perform their duty in professional printers: they transport water and solvent-based inks, replenish ink containers, suck off excess ink at the print head and remove ink decomposition substance for the reserve tanks. In addition, they are used to clean the print head and bleed the ink system.

Miniature pumps from Schwarzer Precision are best equipped for professional printing technology. Chemically resistant elastomers and special non-stick properties of the valves guarantee precise and trouble-free delivery of water and solvent-based inks. Our highly efficient sealing technology meets all leaktightness requirements within the printer system. Apart from fluid and vacuum pumps we also supply special dosing pumps to deliver smallest amounts of ink.

Fluid handling: No chance for cavitation (18.11.2014)

Mechanical vibrations cause pulsations (pressure variations). And these in turn are the cause for cavitation. When the static pressure of a pumped fluid drops below its evaporation pressure, microscopic gas bubbles develop on the vibrating valves. These bubbles are entrained with the flowing fluid and collapse when they come into areas of higher pressure. Our new diaphragm-type fluid pumps eliminate this undesired cavitation process almost completely.

A dramatic reduction of pulsation – this was the paramount development objective for our new diaphragm-type fluid pumps of the 500 /570 EC-L series. Thanks to flow-optimized passages, specific suction dampers and preloaded valves, we succeeded in eliminating the air bubble formation. What is more is an increase of the volumetric capacity by ten percent despite of a considerable reduction of power consumption.

These new types also excel by their optimal control characteristics: the flow rate can be controlled by the applied voltage in a very precise and linear manner. Even in case of dry running, these pumps show an outstanding suction behavior. Their optimized valves are also suitable for condensate pumping (gas-water mixtures).

You get all these advantages in a modular system. By a purposeful combination of shapes and materials, we can manufacture a variety of versions optimized for vacuum, flow or pulsation – tailored to your specific application. We do not waste time with compromises – your pump will be adjusted accurately to your actual requirements.

When it comes to elastomers, we provide a wide range of different shapes, Shore hardnesses and materials (also FDA-approved and free of plasticizers). Brushless motors with the longest service life (>10,000 hours) are now available as drives. Thanks to over-sized ball bearings, they manage even high pressures in continuous duty.

Moreover, our product range includes a full assortment of specific metering and rotary pumps. From standard applications to complex special-purpose systems – we develop the ideal solution. Uncompromising and reliable.

No compromises: Customizing by Schwarzer Precision (28.10.2014)

Schwarzer Precision is known for outstanding consulting quality and custom solutions. Customizing is of utmost importance to us: we develop micro pumps were all parameters will be adapted exactly to your application. At the Medica Compamed 2014 we will present this year’s new development in the area of gas and fluid delivery.

Rotary vane pumps were so far accompanied by the drawback, due to its function principle, that abrasions were caused in rotor and stator by the movement of the vane. Thanks to new material pairing and highly efficient production processes we were able to nearly eliminate these abrasions. At the same time, the life of our vane pumps was increased by another 30 %.

Especially in portable gas analyzers, the new vane pumps of the FZ series are clearly superior to diaphragm pumps: Thanks to their pulsation-free gas delivery they work excellently in combination with sensitive measuring sensors. Additional advantages are its quiet and nearly vibration-free running, the very low current consumption, excellent controllability with linear characteristic as well as the extremely compact external dimensions.

Beyond this, we offer you a complete product range of miniaturized eccenter and rotary diaphragm pumps for gases, fluids and condensates. From the standard to the complex special application, from medical technology to environmental monitoring: We develop the ideal pump for you. Manufactured according to your specifications, exactly matched to your application. Uncompromising and reliable.

Visit us from 12 to 14 November at the Medica Compamed in Düsseldorf, Hall 8A, Booth M 09. We look forward to meeting you there.

Long-distance runner: new vane pump SP 140 FZ (25.09.2014)

So far, diaphragm pumps have dominated in the sphere of gas analyzers. With the very durable vane pumps of the FZ range, there is now an highly interesting alternative.

Due to their design principle, vane pumps (rotary vane pumps) have yet had a disadvantage: abrasion in the rotor and stator by the friction of the vanes. Wear and increasing leakage in the pump chambers are the consequences. Already with our last year's models, we could completely eliminate this disadvantage by optimized manufacturing processes and the use of new materials. We have now succeeded in improving the service life of our FZ types by another 30%.

Thanks to the use of high-strength vane material and an optimized matching between the friction partners, we managed to further reduce the friction coefficient in the pump head. For an adequate driving of this almost wear-free pump unit, bell-type armature motors with a long service life are now used.

At one go, we added a new vane model to our product range: The SP 140 FZ excels by higher flow rates and is suitable for operating voltages from 4.5 to 12 V. These new FZ models can also be used in extreme environmental conditions – they reliably deliver even at -40°C.

Furthermore, our vane pumps also stand out due to freedom from pulsation, a low-noise and low-vibration operation, a very low power consumption, a linear characteristic with excellent controllability and small outside dimensions.

In particular in portable gas analyzers, our new FZ types are far superior in a direct comparison to diaphragm pumps. Thanks to their pulsation-free gas delivery, they work excellently in combination with sensitive measuring sensors. This eliminates the need for pulsation-reducing measures (upstream nozzles, for example). The result: Power consumption can be kept to a minimum, no costs for additional components and smaller battery packs. Moreover, linear fitting dimensions and the hose connection on the face allow a considerably compacter design of small gas analyzers.

Strong SP team at the Essen company run (23.09.2014)

On September 10, 2014, fifteen SP employees turned their after work hours into a sports event participating in the 4th Essen company run. Although the original start time had to be postponed due to a major storm, around 6,000 runners made a start on the 5.1 km long distance from the Aalto theatre to the Grugapark.

From the apprentice up to the manager – common fun and enjoyment of sport were at the focus as our strong SP team started on the Essen company run. Further SP employees, who lined the length of run to the Grugapark, encouraged the runners.

To make sure the physical well-being was not neglected an after-run party was celebrated at the Grugapark – with live music and many culinary highlights.

Pivot pumps: SP patents a fully new pump concept (06.05.2014)

Coil-operated linear pumps (LI range) are perfect for applications that require a high volumetric displacement combined with a very long service life. But this type of pump cannot reach the high pressure and vacuum levels and the compact sizes of motor-operated eccentric diaphragm pumps (EC range) due to physical constraints. Schwarzer Precision has recently filed a patent application for a new drive concept developed from the ground up combining the advantages of linear and oscillating armature pumps with that of eccentric diaphragm pumps.

In conventional coil-operated linear and oscillating armature pumps, the kinetic energy of the coil is straight-lined transmitted to a diaphragm. Our new pivot diaphragm pumps (PA range) are also driven by an iron-core coil, but use the amplifying effect of a mechanical leverage to build up a distinctively higher pressure in the pump head. This leverage has two arms driving two oval diaphragms alternatingly. In this way, a high volume flow rate even at high pressure and also a reduced pulsation of the air flow can be achieved. Thanks to the wraparound clamping of the diaphragms, the pump head cannot suck false air, which results in a medium delivery without any corruption. On top of this, the oval diaphragm shape allows an extremely flat design.

Presumably, this new PA range will go into production from the 3rd quarter 2014. These pumps will be available as AC and DC versions. An intelligent control will be available as an option, which corrects the optimal working point of the pump depending on the present environmental parameters.


SP supports the Deutschland-Stipendium (05.04.2014)

Despite of high numbers of students, Germany will be lacking surpassingly qualified young people in the long term. Already now, there is a lack of skilled labour in many industries. That is why Schwarzer Precision contributes to the "Deutschland-Stipendium" (Germany Scholarship), an income-independent funding of talented academics.

More than 14,000 awarded scholarships – the Deutschland-Stipendium of the Federal Ministry for Education and Research (BMBF) introduced 2 years ago has established in the higher education institutions. Scholars get an extra of Euro 300 per month, fifty-fifty funded from the federal state and from private sponsors (companies, foundations, private persons, etc.) The individual scholarships are competently and neutrally awarded from the institutions of higher education.

For us, a proactive investment in university education is an important factor of success. With this, our company makes a contribution to the future of the business location Germany, becomes part of the knowledge transfer in the university network and comes into direct contact with highly talented young people. In this way, we ensure already today that Schwarzer Precision can remain also in future a technological leader in the development of high-tech miniature pumps.

New diaphragm metering pumps SP 570 EC-LD (15.11.2013)

In sensitive cases conventional liquid diaphragm pumps offer insufficient dosing precision. Until today remedy could only be found by using conventional metering pumps, but unfortunately these pumps are very expensive. Our development engineers have now been able to develop a completely new category of pumps to series-production readiness: the new diaphragm metering pumps SP 570 EC-LD combine high metering precision with low manufacturing costs.

The intelligent design and the flow-optimized valve technology of the new SP 570 EC-LD allows linear control of the delivery volume over a wide control range. High repeatability and self-priming even after running dry are other advantages of this design. Tubing for various connectivity options (push-in fittings, hose barbs, O-rings) are available.

By specific over-sizing of mechanical wear parts a long durability is achieved. Resistant materials are available for aggressive media. The pumps are available with many different motors: from low-cost iron core motors to long-life brushless motors, with analog or PWM control.

All these benefits of our new metering pumps are offered to you at a surprisingly affordable price. We invite you to visit us on November 20-22 at the MEDICA / COMPAMED tradefair in Dusseldorf, Hall 8A, Stand M 09 to introduce you to the pump technology of tomorrow!


Certification as family-friendly company (04.08.2013)

The Essen Audit is a cooperative project for the certification of family-friendliness in companies in the city of Essen. The focus lies here on the family – job balance. Companies from Essen can submit to a voluntary certification procedure with various checks. In the end, their family-friendliness is rated by a signal light system and awarded the family seal. Schwarzer Precision is one of the first companies which got the family-friendly certificate by the Essen Audit.

A single mother has to leave the meeting early because the toddler in kindergarten is running a fever. A dad has a demanding job, at home he needs to support his working wife by taking care of the children. Single parents, family members in need of care, both parents working – the demographic change increasingly challenges companies to a paradigm shift. New offers need to be created to help employees maintain a good family – job balance.

Family-friendly personnel policies create satisfied, qualified and motivated employees – this insight exists not only in theory at Schwarzer Precision but has long been practiced as a matter of course. Flexible working hour arrangements and part-time models are part of our everyday work life just as much as the systematic support when returning to work. To improve even more we have applied for certification as family-friendly company. After several months of subjecting ourselves to the multi-stage checks and consultations of the Essen Audit we got the family-friendly award as one of the first companies.

Health Care for our employees (03.07.2012)

Schwarzer Precision manufactures high-quality micro pumps for the demanding area of medical technology. Employed in respiratory monitors and anesthesia units utmost reliability is an absolute must – because this technology saves lives! We are keenly aware of this responsibility: Our devices are engineered at the highest quality level and pass through stringent checks and stress tests during the entire production.

We exercise this responsibility also with the health care of our employees. We participate, for example, in the initiative "Saving 1000 lives / Ruhr - Staying healthy through colon cancer prevention". Colon cancer belongs to the most frequent types of cancer: 27,000 people die each year of this disease – although it could be prevented through simple preventive medical examinations.

All of our employees are therefore provided with the opportunity of a free immunologic examination, which is not covered by the health insurers. Participation as well as the test results remain anonymous, of course. In case of positive findings, the participating employees are exclusive advised by the commissioned testing institution about further therapeutic measures.

We thereby not only contribute to reliable medical technology provision but already to the prevention of dangerous diseases.


RO Design Type Program significantly expanded (01.06.2012)

To manufacture the worldwide best miniature pumps for medicine, analysis and laboratory technology - this is the quality claim of Schwarzer Precision. Based on this aspect, our rotation diaphragm pumps (RO design type) have been subjected to a stringent revision during the past months. The new RO generation offers a greater type variety than ever before – with their performance improved even more.

Rotation diaphragm pumps (or rolling pumps) are marked by especially low-pulsation delivery. Contrary to eccentric diaphragm pumps rotation pumps are equipped with several small diaphragms actuated sequentially. Thus a very continuous volume flow, nearly linear pressure characteristic curve and running characteristics almost free from pulsation and vibration are achieved.

The SP 30 RO rotation pump is now also available as vacuum pump. The type SP 30 RO-V generates a vacuum of 640 mbar at a free flow of 3.7 l/min. Dimensions and weight are identical with the pressure version SP 30 RO-DV.

The modular types SP 16 RO-DV and SP 18 RO-D are now available in additional motorization versions. Our customers can choose between particularly compact dimensions (short motor) or especially low current consumption (longer motor). The direction of the hose connection necks is also freely configurable.

The SP 27 RO-D rotation pumps have received optimized diaphragms and higher quality bearings. Thus they now reach pressures up to 1000 mbar. The performance of the also available vacuum version SP 27 RO-VD could be increased to -600 mbar.

Schwarzer Precision therefore now offers the worldwide largest product range of maximum quality miniature rotation pumps.

Clearly superior: Diaphragm pumps outperform piston pumps (23.02.2012)

Piston pumps used to be the preferred technology as soon as rather high pressures and large delivery volumes are needed. Because of warp-resistant plungers and large strokes they achieved performances that did not seem possible with a fixed elastomer diaphragm of the same size. These scenarios are now reversed through the consistent ongoing development of our eccentric diaphragm pumps. The new models of the EC Series 600 are superior to the piston pump in every respect – thus becoming the better alternative!

The principle is already known from the combustion engine: Increasing compression is the most effective measure to enhance performance. After comprehensive test series our development department has realized a clearly optimized roll-off behavior of the diaphragm allowing to further minimize the dead volume in the pump head. The consequence: The diaphragm pumps achieve higher flow rates than the piston pumps at the same pressure and same vacuum!

But that’s not all: The breakthrough of this diaphragm technology for the first time eliminates all drawbacks that were unavoidable with the use of a piston pump. The system-inherent friction losses of a plunger are accompanied by increased wear, causing higher nose levels and more heat development. The oscillating plunger mass produces greater imbalances. At the same time, smallest leaks on the plunger prevent a gas-tight design.

The new diaphragm pumps at the same performance are significantly less noisy, quieter in running and have less wear than the piston pumps. The fixed membrane closes the pump head absolutely tight; indispensible for absolutely true delivery of the medium. A modified elastomer mix maximizes the service life of the membrane, even at highest pressures and vacuum.

Because of these clear advantages of diaphragm pumps the piston pumps (series PI, types 628 PI) are now obsolete: They will be replaced by the superior EC Series 600. Available in a large variety of single and dual-head types (e.g. 620 EC, 620 EC-DU), brush and BL motors (622 EC-BL, 622 EC-BL-DU), pressure and vacuum-optimized heads (types DV and VD) these diaphragm pumps at the same time permit a much more exact adaptation to any specific customer requirement.

Easy controllable: new rotary pump 032 RO-D (18.01.2012)

Maximum quietness in running, extremely tight pump heads and very compact assembly dimensions predestine the rotary diaphragm pumps from Schwarzer Precision for use in professional blood pressure measuring units and demanding applications of the consumer goods industry.

Their nearly linear ratio between applied voltage and resulting flow rate makes these miniature pumps particularly exact and easy to control. Our successful rotary diaphragm pump 030 RO-DV is now replaced by the further optimized 032 DO-D. A modified valve and diaphragm technology makes this type even quieter as its already quiet running predecessor. At the same time, the maximum pressure and flow performance could be further increased at nearly identical outside dimensions. An optimal price-performance ratio makes this diaphragm pump the choice number one in large series production.

World’s smallest dual-head diaphragm pump: SP 100 EC-DU (16.12.2011)

The development of increasingly smaller miniature pumps so far ran against physical limits making a further reduction of the dimensions problematic. Even smallest valves, for example, therefore respond increasingly more sluggish since the density of the delivered medium is not likewise reduced proportionally. The consequence: A certain minimum size could not be reduced any further.

The application of the company’s proprietary hrV technology (High Response Valves) facilitated the development of a completely new solution successfully eliminating this problem. In addition to the smallest vane pumps and rotary pumps Schwarzer Precision now also offers the world’s smallest eccentric membrane pumps with the EC Series 100.

The dual-head 100 EC-DU now follows as the latest addition to this series. This pump opens a wide field of new application areas: The delivery of two different media is now possible also in the most compact handheld devices. The dual-head configuration offers clear advantages even if only one medium is to be delivered. On the one hand, two small membrane surfaces, operated with a smaller stroke, produce a markedly reduced pulsation as compared to a single larger diaphragm. Uncontrolled responses of pressure sensors are thereby deliberately prevented. On the other hand, the two pump heads can be operated in parallel (nearly doubled flow rate) or connected in series (markedly higher pressure or vacuum).

The minute dimensions, the low current consumption and a weight of only 17 grams predestine these membrane pumps, e.g. for portable gas analysis devices. A low structural height of only 13 mm and the variable connecting pieces (outlet possible in four different directions) ensure the uncomplicated installation in smallest devices. The completely modular structure of our pumps allows optimal configuration for your specific application. A large selection of different diaphragms and valves as well as a wide variety of motor types are available to this end. In addition to iron core and bell type armature motors brushless motors with integrated drive electronics are now also available.

SP builds new corporate headquarters at M1 industrial park (05.09.2011)

Larger, more flexible and greater performance – those were the main requirements when planning the new SP corporate offices. The building permit is now on the table and ground breaking will start already in September.

The current company premises in the inner city of Essen simply did not allow for any further expansion. Instead of remodeling once more the decision was made in favor of new corporate offices. Especially our research and development department will benefit from the new four-level building in the modern M1 industrial park. Our engineers will have four times the present space available. Additional analysis and test labs manifest our constantly growing quality demands as technology leader in the market for hi-tech pumps for the sectors of medicine, analysis and environmental technology.

Production and administration will also enjoy the new rooms. An optimized workflow and greater capacities with individual customer support will also contribute to continuously guaranteeing the customary high SP quality level. Bright and well illuminated working facilities and a large roof terrace provide our employees with a pleasant working climate. And last not least, the infrastructure setup makes for more convenient access and optimized logistics.

The new company center thus fully underlines our motto "We care". Completion is scheduled for the summer of 2012.

570 EC: new standards through technological innovations (05.02.2011)

Based on the successful model series EC 500 the SP 570 EC became a pump expanded by two innovative technologies. First, the delivery channels in the pump head were revised and their flow properties optimized. This has become possible through Schwarzer Precision’s innovative NT technology (No Turbulence Technology). Secondly, the new IBE active balancing system (Individually Balanced Eccentric) provides the pump with amazingly quiet running characteristics.

Compared with conventional diaphragm pumps, the SP 570 EC optimally utilizes the installation volume. It delivers maximum pump output even in the smallest available space. The economically priced modular system makes individual modifications toward the perfect customized pump possible and desirable without problems.

For example, different valves and diaphragm geometries can be employed to achieve high flow rates, pressures or vacuums. Motors of different manufacturers – from the low-cost to the high-end brushless motor – can be integrated. In addition, components in contact with the flow media can be PTFE-coated (Teflon) at little extra cost to further enhance corrosion resistance.

The life of the new miniature pumps is increased by a two-bearing drive shaft and withstands also high pneumatic pressures. Mounting holes at the three sides of the pump permit installation in any position desired.

New 620 EC / 625 EC: doubled free flow! (27.11.2006)

These pumps are a modification of our well-proven SP 600 EC. Thanks to a revolutionary diaphragm / valve design we were able to double the free flow performance without increasing the rpm of the motor! The high flow in combination with the small dimensions predestines these pumps for gas analysis devices. The pumps are equipped with long life motors and double ball bearings. They are also available with brushless motors.
