Radial Piston Pump PR4-3X/8,00-700RG12M01 - Bosch Rexroth R901089817

A maximum operating pressure of 700 bar at a delivery of 11 l/min defines where the radial piston pump PR4-3X/8,00-700RG12M01 belongs. The fixed displacement pump with ten pistons draws 8 cm³ per revolution, turns clockwise and weighs 12.71 kg. The housing is cast iron.

Benefits

• 700 bar maximum operating pressure at 11 l/min delivery
• Ten pistons, constant displacement of 8 cm³
• Shaft end with serration 21 x 24 to DIN 5481, clockwise rotation
• 4-hole fastening with 63 mm centering, no through-drive
• 12.71 kg, cast iron housing, NBR seals, HLP hydraulic fluid

Application

High pressure pumps of this class supply clamping fixtures, joining presses and test equipment in an open circuit. The small delivery is intentional, since at 700 bar the point is force rather than speed. Ten pistons keep pulsation low, which benefits the service life of seals and hoses.
