Radial Piston Pump PR4-3X/1,60-700RA12M01 - Bosch Rexroth R901093640

Clamping fixtures, press tools and test benches rarely need large flows, but they do need pressure well above the usual machine level. The PR4-3X/1,60-700RA12M01 radial piston pump works with three pistons and a constant displacement of 1.6 cm3 and provides 2 l/min at operating pressures up to 700 bar.

Key benefits

• 700 bar maximum operating pressure in an open circuit, without an additional pressure intensifier
• Constant displacement of 1.6 cm3 giving 2 l/min, which makes cycle times easy to calculate
• Cast iron housing, built for continuous industrial duty
• Clockwise drive through a cylindrical shaft end of 25 mm diameter with fitting key to ISO 3019-2
• 4-hole fastening with 63 mm centering, connection diagram 1, no through-drive
• NBR seal for HLP hydraulic fluid, weight 9.17 kg

Application

The pump serves high pressure clamping systems, press tooling and test equipment where a small flow at a high pressure level is required. Because displacement is constant, pressure is limited by valves in the circuit rather than controlled at the pump. The direction of rotation is fixed and has to be respected when the motor is fitted.
