Radial Piston Pump PR4-3X/20,00-500RA01M11 - Bosch Rexroth R901089604

Ten pistons produce an even flow of 26.5 l/min at 500 bar operating pressure here. Displacement stays constant at 20 cm³ and is set through the drive speed. The pump is intended for an open circuit with HLP hydraulic fluid and runs clockwise.

Benefits

• Ten pistons for an even flow of 26.5 l/min
• Constant displacement of 20 cm³, operating pressure up to 500 bar
• Cylindrical shaft end Ø 25 mm with fitting key to ISO 3019-2
• 4-hole mounting flange with 63 mm centering, without through-drive
• Clockwise direction of rotation, HLP hydraulic fluid
• 15 kg mass, NBR seals, cast iron housing

Application

The pump is used in clamping devices, high pressure power units and test rigs with a small oil demand. As there is no through-drive, it sits at the end of the drive train. The 4-hole flange with 63 mm centering fixes the alignment to the motor.

Manufacturer

Bosch Rexroth lists this radial piston pump PR4-3X/20,00-500RA01M11 under material number R901089604. Without a through-drive no second pump can be flanged on, which belongs in the power unit planning.
