Radial Piston Pump PR4-3X/20,00-500RA01M01 - Bosch Rexroth R901089313

This version of the PR4 series differs in its port arrangement and weighs 17.13 kg. The ten radial pistons deliver a constant 26.5 l/min at operating pressure up to 500 bar.

Benefits

• 17.13 kg weight in this port version of the PR4 series, cast iron housing.
• Constant displacement of 20 cm³ at 26.5 l/min flow.
• Operating pressure up to 500 bar in open circuit on HLP hydraulic fluid.
• Cylindrical shaft end Ø 25 mm with fitting key to ISO 3019-2, clockwise rotation.
• Mounting flange, 4-hole fastening, 63 mm centering, connection diagram 1.
• NBR seals and a version without through-drive.

Application

Typical duty is tool and clamping hydraulics, where a small flow at very high pressure is required. The ten pistons spread delivery across one revolution and keep pulsation low. Leaving out the through-drive keeps the overall length short.
