Radial Piston Pump PR4-3X/8,00-700RA12V01 - Bosch Rexroth R901121470

The PR4-3X/8,00-700RA12V01 is a radial piston pump with constant displacement for open circuit duty. It delivers 11 l/min at a maximum operating pressure of 700 bar, turns clockwise and weighs 17.01 kg. The drive shaft is cylindrical, 25 mm diameter, with a fitting key to ISO 3019-2.

Benefits

• 700 bar maximum operating pressure, reached through the 10-piston radial design
• Constant displacement of 8 cm3 at 11 l/min flow
• Cylindrical shaft 25 mm diameter with fitting key to ISO 3019-2
• 4-hole fastening with 63 mm centering, cast iron housing, 17.01 kg
• FKM seal for HLP hydraulic fluid, version without through-drive

Application

The pump feeds clamping and test hydraulics, presses and tool holding systems that need small oil volumes at very high pressure. Because it is laid out for clockwise rotation, the direction of the drive has to be checked before coupling. Without a through-drive no second pump can be flanged on.
