Radial Piston Pump PR4-3X/20,00-500RG01M08 - Bosch Rexroth R901277726

Clamping hydraulics and press tooling need high pressure at a moderate delivery rate, which favours a radial piston design. The fixed displacement pump PR4-3X/20,00-500RG01M08 works with ten pistons, a displacement of 20 cm3 and supplies 26.5 l/min at up to 500 bar.

Benefits

• Operating pressure up to 500 bar at a flow of 26.5 l/min.
• Constant displacement of 20 cm3, ten pistons in radial arrangement.
• Clockwise rotation, without through-drive, cast iron housing for continuous industrial duty.
• Shaft end as serration 21 x 24 to DIN 5481, 4-hole fastening with 63 mm centering.
• Laid out for HLP hydraulic fluid, NBR seals, weight 16.14 kg.

Application

The pump supplies clamping fixtures, presses and test rigs in an open circuit where pressure matters more than volume. The serration to DIN 5481 couples it to the drive motor and the four-hole flange centres over 63 mm. The direction of rotation is clockwise and has to be observed when mounting.

Manufacturer

Bosch Rexroth lists the pump as type PR4-3X/20,00-500RG01M08 of product family PR4 under material number R901277726.
