Ensuring constant, optimal system pressure and smooth interaction between the transmission components

The regulated VPG vane pump supplies exactly the right amount of oil and pressure that is needed for shifting and coupling in passenger car transmissions. In addition, the VPG also supplies the transmission components with oil for lubrication and cooling.

Up to 40%*

lower power consumption compared to unregulated transmission pumps
*dependent on the load spectrum and the control strategy of the transmission

designed for high-performance applications

Flexible design

Modular assembly system

We would also be happy to customize our solutions optimally to your individual wishes and requirements. Our versatile modular assembly system gives you so many different options.

The VPG can be used as a cartridge solution (without a pump housing) in the existing transmission housing or mounted via its own housing in the transmission.

With its energy-saving design, the VPG transmission pump ensures optimum system pressure for maximum transmission performance.

Function

Energy-saving pump for maximum transmission performance

The VPG transmission pump consists of an optional housing, cover, front plate, shaft and a rotor set. The rotor set is comprised of a rotor, radially-guided blades in the rotor as well as the cam ring and outer ring.

The position of the cam ring is hydraulically adjustable. The VPG behaves like an unregulated pump up to a defined control point. As soon as this control point is reached, the position of the cam ring is adjusted and the volume flow is regulated to the preset value. The decreased delivery volume reduces the power consumption, which lowers the system temperature in the transmission.
