Radial Piston Pump PR4-3X/6,30-700RA12M12 - Bosch Rexroth R901132571

High forces on small cylinders come from pressure, not from delivery volume. The PR4-3X/6,30-700RA12M12 radial piston pump supplies up to 700 bar operating pressure at a flow of 9.5 l/min.

Benefits

• 700 bar maximum operating pressure from a constant displacement of 6.3 cm³.
• 10 pistons, so delivery is spread across many individual strokes.
• Cast iron housing, laid out for continuous industrial duty in an open circuit.
• Shaft end cylindrical Ø 25 mm with fitting key to ISO 3019-2 and 4-hole fastening with 63 mm centering.
• 16.98 kg, clockwise rotation, without through-drive, NBR seals for HLP hydraulic fluid.

Applications

The pump feeds clamping systems in tool making, hydraulic pressing fixtures and test equipment that call for pressures above the usual plant level. Because displacement is constant, pressure is governed by the valve technology downstream. An open circuit with HLP hydraulic fluid is what it is built for.

Manufacturer

Bosch Rexroth, material number R901132571. Frame size 6.3 cm³, clockwise rotation and the 4-hole fastening with 63 mm centering define how the pump mounts to the drive.
