Hawe R and RG Radial Piston Pumps


The Hawe radial piston pump type R and RG consist of valve-controlled pump elements arranged in star form around an eccentric. For large flow rates, up to 42 pump elements can be set up, consisting of 6 stars stacked one above the other. The pumps’ output volume is merged to feed one or more pressure outlets. This system is optimised for a very high efficiency.

The radial piston pump type R and RG have a closed pump housing. This allows it to be used in two configurations. First, as an external motor pump outside an oil tank or integrated and installed inside a hydraulic power pack’s tank (see D 6010 H). The type RG pump has plain bearings which have an extended service life.

Both the Hawe type R and RG pumps operation is not dependent upon the direction of rotation. The design also allows for a fine delivery in flow rate gradation and both can run on a low viscosity oil if required.

Summary technical specifications of the Hawe R and RG type motors include:

  • Displacement: 1.59 – 64.18 cc/rev
  • Flow rate: 2.27 – 91.2 litres per minute
  • Peak pressure: 700 bar

Common applications include: industrial hydraulics, testing machinery, lubrication systems and hydraulically operated tools
