Radial Piston Pump PR4-3X/16,00-500RA01M01-C3.1 - Bosch Rexroth R901376896

A clamping circuit needs force, not volume. That is what the radial piston pump PR4-3X/16,00-500RA01M01-C3.1 is built for. From a constant displacement of 16 cm³ it reaches a maximum operating pressure of 500 bar at up to 22 l/min in an open circuit.

Benefits

• Maximum operating pressure of 500 bar from a displacement of 16 cm³.
• Ten radial pistons spread delivery across the revolution and keep noise and pulsation low.
• Constant displacement at up to 22 l/min gives predictable circuit behaviour without control effort.
• Cylindrical shaft Ø 25 mm with fitting key to ISO 3019-2 and 4-hole fastening with 63 mm centering fit common drive bell housings.
• 16.01 kg cast iron housing with NBR seals for HLP hydraulic fluid.

Applications

Typical places are clamping fixtures, small presses and test rigs where a cylinder works with high force over a short stroke. The pump delivers into an open circuit and comes without a through-drive, so it sits as a single unit on the drive. Direction of rotation is fixed as clockwise.

Manufacturer

Bosch Rexroth lists this radial piston pump under material number R901376896. Cast iron housing and NBR seals are matched to HLP hydraulic fluid in continuous industrial duty.
