Radial Piston Pump PR4-3X/6,30-700RA01V01 - Bosch Rexroth R901089564

The PR4-3X/6,30-700RA01V01 is the radial piston pump with 6.3 cm3 displacement and 9.5 l/min flow. Maximum operating pressure is 700 bar. Lower flow at the same pressure reduces the drive power required, which allows a smaller motor.

Benefits

• Displacement 6.3 cm3 with 9.5 l/min flow at 700 bar
• Lower flow, therefore less drive power at the same pressure
• Constant displacement, 10-piston design in a cast iron housing
• Shaft end cylindrical, 25 mm diameter, fitting key to ISO 3019-2, clockwise rotation
• FKM seal for HLP hydraulic fluid, no through-drive, 16.71 kg

Application

The pump feeds high pressure circuits where small volume cylinders move slowly, for example in clamping and test hydraulics. If flow is larger than needed, the surplus goes across the relief valve and heats the oil. The smaller frame size avoids that.
