Radial Piston Pump PR4-3X/8,00-700RA12M02 - Bosch Rexroth R901093873

Ten pistons spread the delivery over many small strokes, which keeps the pump running smoothly even at 700 bar operating pressure. The constant displacement of size 8 cm³ yields up to 11 l/min, and the cast iron housing takes up the forces.

Benefits

• Operating pressure up to 700 bar in an open circuit on HLP hydraulic fluid
• Constant displacement of size 8 cm³ with a flow of up to 11 l/min
• Ten pistons keep pressure pulsation low, and the cast iron housing damps it further
• Cylindrical shaft end Ø 25 mm with fitting key according to ISO 3019-2
• Mounted by 4-hole fastening with a centering of 63 mm, connection diagram 2
• NBR seals, clockwise rotation, weight of 17.52 kg

Applications

Radial piston pumps of this design feed clamping hydraulics, press tools and test rigs with high pressure at a small flow. 700 bar and 11 l/min suit cylinders with a short stroke and a large force. Without a through-drive, the drive shaft stays reserved for this pump alone.

Manufacturer

Bosch Rexroth lists this pump of product family PR4 under material number R901093873. The ordering code PR4-3X/8,00-700RA12M02 states the displacement and the pressure rating.
