Rotary Piston Pumps

A rotary piston pump is a form of hydraulic pump. The working pistons extend in a radial direction symmetrically around the drive shaft

These kinds of piston pumps are characterized by the following advantages:

• high efficiency
• high pressure
• low flow and pressure ripple
• low noise level
• very high load at lowest speed due to the hydrostatically balanced parts possible
• no axial internal forces at the drive shaft bearing
• high reliability

Due to the hydrostatically balanced parts it is possible to use the pump with various hydraulic like mineral oil, biodegradable oil, HFA (oil in water), HFC (water-glycol), HFD (synthetic ester) or cutting emulsion.
