Vanes, Rotors & Housings for Vane Cell Pumps

Chrisitian Bauer GmbH + Co. is a manufacturer of ground precision vanes, rotors and housings for vane pumps as well.

The rotor contains multiple vanes which slide in radial slots. The rotor and outside casing (housing) are eccentric. The vanes maintain contact with the casing by centrifugal force and pressure (spring loaded).

• The dimensional tolerances of the vanes and the rotor slots present a great challenge since the required accuracy is in the Micrometer-Range (1µ m = 0.001 mm = 0.00004").
• Ground parts in flat or cylindrical shape as
  required for functionality.
• Lot size up to 100,000 / day.

Achieving the required high and demanding tolerances results in vane pumps running quietly and with high efficiency. Christian Bauer GmbH + Co. vane cell pump parts have been in use with great success in the European Automotive industry for years.
