Radial Piston Pump PR4-3X/8,00-500RA01V08 - Bosch Rexroth R901154173

Where the drive motor is sized tightly, displacement governs the torque required at the shaft. The radial piston pump PR4-3X/8,00-500RA01V08 works on 8 cm³ per revolution, delivers 12 l/min and withstands a maximum operating pressure of 500 bar.

Benefits

• Constant displacement of 8 cm³ per revolution, five pistons.
• 12 l/min flow at a maximum operating pressure of 500 bar.
• FKM seals and cast iron housing for HLP hydraulic fluid in an open circuit.
• Shaft end cylindrical Ø 25 mm with fitting key to ISO 3019-2, 4-hole fastening with 63 mm centering.
• 11,05 kg, clockwise rotation, without through-drive.

Applications

The pump drives clamping circuits, pressing fixtures and test rigs that need little oil at high pressure. The smaller displacement lowers the drive torque required compared with the 10 cm³ version. Mounting and shaft end match the rest of the series.

Manufacturer

Bosch Rexroth, material number R901154173. Frame size 8 cm³, direction of rotation and the 4-hole fastening with 63 mm centering define how the pump attaches to the drive.
