Any high-pressure application is basically possible.

Areas in which a constant flow rate is necessary.

The radial piston pump type R 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 in 6 stars stacked one above the other.

The pump elements'output volume is merged to feed one or more pressure outlets.

The radial piston pump types R and RG have a closed pump housing. It can consequently be used both as 

an external motor pump not installed in an oil tank or as an integrated version installed inside a hydraulic 

power pack's tank. The radial piston pump type RG has plain bearings which have an extended service life.

The radial piston pumps are valve-controlled with cylinders in a radial arrangement. The cylinder radials, 

arranged in one, two or moresuperimposed layers (rows), are driven by bearings 8 tted eccentrically on the

drive shaft (piston pressure stroke), and reset by a spring (piston suction stroke). 

The delivery flows of the individual cylinders are brought together in collecting 

plates feeding a joint pressureconnection (P). The housing shells are load-bearing elements 

supporting the cylinders and shaft bearings. The pumps are largely statically and dynamically balanced,

resulting in smooth running. With the exception of the 1 and 2-cylinder pumps, an uneven number

of pistons is used per cylinder radial, so that the pulsation of the delivery flow is minimised from three cylinders upwards.
