Radial Piston Pump PR4-3X/6,30-700RA01M02 - Bosch Rexroth R901088888

The smaller the displacement, the less torque the pump draws from the motor at the same pressure. At 6.3 cm³ per revolution this ten piston unit delivers up to 9.5 l/min while working at an operating pressure of up to 700 bar.

Benefits

• Displacement of 6.3 cm³ and a flow of up to 9.5 l/min, matched to small high pressure consumers
• Operating pressure up to 700 bar in an open circuit on HLP hydraulic fluid
• Ten pistons in a cast iron housing, constant displacement without any adjusting mechanism
• Cylindrical shaft end Ø 25 mm with fitting key according to ISO 3019-2, clockwise rotation
• 4-hole fastening with a centering of 63 mm to connection diagram 2
• NBR seals, weight of 16.28 kg

Applications

This size feeds single clamping points, test cylinders and high pressure test rigs where little oil flows. Because the displacement is constant, the flow follows the drive speed. Without a through-drive the pump sits alone on the motor flange.

Manufacturer

Bosch Rexroth lists this pump of product family PR4 under material number R901088888. The ordering code PR4-3X/6,30-700RA01M02 states the displacement and the pressure rating.
