Vacuum Pumps

Nothing doing without them. Diesel or gasoline engines alike, more and more vehicles nowadays depend on specific vacuum pumps. These pumps generate the vacuum needed for boosting brake performance, vacuum which is also required for controlling servo systems and exhaust gas recirculation.

We have developed the vacuum pump system which is most frequently used today, the single-vane design, into a highly cost-competitive version that perfectly addresses our customers' vacuum needs in every respect. The pump features a rotary drive and is available in 4 different standard sizes ranging from 130 cm3, to 260 cm3. Its low power intake is attributable to the design principle applied and reduces fuel consumption; in addition, it can be fitted with separate vacuum ports for brake boosters and servo devices.

Less is often more: in designing the single-vane vacuum pumps, we had their production costs in mind right from the start. As a result, we succeeded in keeping them lean with a minimum of parts and machining operations. So they are not only robust, but also highly cost-efficient. We did not lose sight of environmental aspects either: all materials used for the single-vane vacuum pump are easily recyclable.

The single-vane vacuum pumps come ready for installation, with customer-specific vacuum port, oil tube for pressure lubrication directly via the camshaft plus, if necessary, an element for sealing the pump against the cylinder head.

Depending on engine requirements, rotation is clockwise or counterclockwise. Another advantage: viable integration solutions ideally addressing the trend of carmakers towards modular assemblies that occupy as little space as possible. In other words: pumps with different functions such as oil and vacuum pumps, for example, can be modularized and combined in an evermore reduced space.

Moreover, existing products are undergoing constant optimization in order to improve the efficiency of the pump itself and increase its efficiency in interaction with the engine. To this end, new materials are tried and applied and controllable or electrically assisted systems developed.
