Radial Piston Pump PR4-3X/6,30-700RA01M12 - Bosch Rexroth R901088910

When a pump is mounted to an electric motor, shaft end and fastening decide whether an adapter is needed. The PR4-3X/6,30-700RA01M12 offers a cylindrical shaft end Ø 25 mm with fitting key to ISO 3019-2 and delivers 9.5 l/min at pressures reaching 700 bar.

Benefits

• Shaft end cylindrical Ø 25 mm with fitting key to ISO 3019-2, a standardised interface to the drive.
• 4-hole fastening with 63 mm centering for mounting to the motor flange.
• 700 bar maximum operating pressure at 9.5 l/min flow.
• Constant displacement of 6.3 cm³ from 10 radial pistons.
• 16.48 kg, cast iron housing, NBR seals for HLP hydraulic fluid.

Applications

The pump is used in high-pressure power units for clamping technology, tool making and fixture construction. Clockwise rotation has to be taken into account when the drive motor is chosen, and no through-drive is fitted. An open circuit with HLP hydraulic fluid is the intended mode of operation.
