Hawe RZ Dual-Stage Radial Piston Pump


The Hawe RZ series radial piston pump consists 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 RZ radial piston pump is a dual-stage pump with a closed 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 Hawe type RZ pump’s 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 RZ pump include:

  • Displacement: 1.59 – 89.6 cc/rev
