Polyhydron Radial Piston Pumps


Radial piston pumps (fixed displacement) are used especially for high pressure and relatively small flows. Pressures of up to 650 bar are normal.
These kinds of piston pumps are characterized by the following advantages:
• High efficiency
• High pressure (up to 1000 bar)
• Low flow and pressure ripple (due to the small dead volume in the workspace of the pumping piston)
• 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



Applications
• following main applications for a radial piston pump:
• Machine tools (e. g. displace of cutting emulsion, supply for hydraulic equipment like cylinders)high pressure units (HPU) (e. g. for overload protection of presses)
• Test rigs
• Automotive sector (e. g. automatic transmission, hydraulic suspension control in upper-class cars)
• Plastic- and powder injection moulding
• Wind energy
