Error! Style not defined.
The radial piston pumps may only be operated as a component part of a higher-level overall
system, for example a machine.
The radial piston pumps may be used in hydraulic systems as control elements for volume flow
control, pressure control and power control. Qualified hydraulic fluids are Mineral Oil, oil in water
emulsions (HFA, HFB), water glycol (HFC), synthetic ester (HFD), Cutting Emulsion and Cutting
Oil, Isocyanides, Polyol and Skydrol.
