Radial Piston Pump PR4-3X/6,30-700RA01M01 - Bosch Rexroth R901088879

Shaft end and flange define how the unit joins the drive. On the PR4-3X/6,30-700RA01M01 these are a cylindrical Ø 25 mm shaft end with a fitting key to ISO 3019-2 and a centering of 63 mm. Delivery is 9.5 l/min at up to 700 bar.

Benefits

• Shaft end cylindrical Ø 25 mm with fitting key to ISO 3019-2
• 4-hole fastening with 63 mm centering, clockwise rotation
• Delivery of 9.5 l/min from 6.3 cm³ of constant displacement
• Operating pressure up to 700 bar in an open circuit
• Ten pistons, cast iron housing, weight 16.28 kg
• NBR seals for HLP hydraulic fluid

Application

When replacing a unit in an existing power pack the coupling can stay as long as shaft end and centering match. Without a through-drive the unit sits as a single stage on the motor. For high pressure circuits at 9.5 l/min this is the matching frame size.
