Radial Piston Pump PR4-3X/20,00-500RA12M02 - Bosch Rexroth R901107090

Where 500 bar is required but consumption stays small, a radial piston pump is the right design. The ten-piston PR4-3X with constant displacement delivers 26.5 l/min in an open circuit.

Benefits

• Maximum operating pressure of 500 bar at a constant displacement of 20 cm3.
• 26.5 l/min of delivery from ten pistons, which benefits pulsation behaviour.
• Cylindrical shaft end of 25 mm diameter with fitting key to ISO 3019-2, clockwise rotation.
• 4-hole mounting flange with 63 mm centering for direct assembly onto the drive.
• Cast iron housing and NBR seals for HLP fluid, weight 16.6 kg.

Applications

This design serves clamping and test hydraulics, press tooling and industrial high-pressure units. The open circuit and the cast iron housing suit stationary continuous duty. A through-drive is not provided on this version.

Manufacturer
