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.

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.

The "Große Preis des Mittelstandes" (Grand Award of SMEs), awarded by the Oskar-Patzelt foundation, is Germany's most coveted economic award. (DIE WELT). Companies excelling in the selection criteria "positive overall development, high innovative power, service, customer orientation, marketing as well as the creation and preservation of employment" are nominated.

Schwarzer Precision belonged to the six distinguished finalists of North-Rhine Westphalia already in the previous year. In this year’s competition the company was able to qualify also in the final round and was distinguished as "Price winner of the Großer Mittelstandspreis". The honorific speech states, among others: "The company exercises a great degree of responsibility following the motto 'We care'. An impressive increase in turnover and a constantly growing workforce attest to the company’s quest for long-term development." The minister of economy of the federal state Saarland, Dr. Christoph Hartmann, underlines: "The price winners belong to the elite of Germany’s small and medium-sized businesses; they shape the image of their regions."

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.

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.
