UNICEF - Donations instead of gifts (17.11.2017)

A useful and lasting alternative to expensive Christmas presents is a donation to UNICEF. With such a donation, we will give children all over the world a chance for a better future.

Most refugee children have to leave their home hastily. For their dangerous flight, they leave everything behind. All that remains of the belongings that they once had – books, toys or clothes – is a sad memory.

UNICEF helps those children with clean drinking water and medicine, winter clothes and heating fuel as well as tent schools, toys and teaching materials.

This year again, Schwarzer Precision supports the "Donations Instead of Gifts" campaign actively. Therefore, we will transfer the full amount that was intended for Christmas presents for our customers to the UNICEF children's centres. For the most beautiful Christmas present is a child's smile.

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!

Schwarzer Precision doubles operating space (23.09.2016)

Just 4 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 is in the planning stage and will more than double our operating space.

"SP-2" – this is the internal code for our new construction project on the adjacent property – shall create room especially for highly specialized production technologies. Our research and development labs will also be significantly expanded once more. Medical and laboratory equipment can then be manufactured in a controlled cleanroom climate.

A precision injection molding department is created for the production of 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. Our primary focus with all this is our customers: very special requests and preferences can now be implemented even faster and more exactly.

Our current corporate headquarter was nominated for the BDA architecture award already in 2014. This high level will be maintained also with the design of the new five-floor "SP2" building. Planning is fully underway; construction will commence in 2018.

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.

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.

All parameters of our pumps can be exactly adapted to customer specifications. We also realize special requests such as alternative manifold solutions or external pulsation dampers to ensure trouble-free operation on sensitive print sensors.

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.

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.

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.

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.
