Radial Piston Pump PR4-3X/8,00-700RA01M12 - Bosch Rexroth R901089169

In the high-pressure range, the time it takes to reach clamping pressure is a question of delivery. The PR4-3X/8,00-700RA01M12 radial piston pump works with 8 cm³ displacement and supplies up to 11 l/min from it at operating pressures reaching 700 bar.

Benefits

• 11 l/min from 8 cm³ constant displacement, so the cylinder reaches the set pressure without waiting.
• 700 bar maximum operating pressure in an open circuit.
• 10 pistons in radial arrangement with a cast iron housing.
• Shaft end cylindrical Ø 25 mm with fitting key to ISO 3019-2, 4-hole fastening with 63 mm centering.
• 16.28 kg, clockwise rotation, without through-drive, NBR seals for HLP hydraulic fluid.

Applications

The pump drives clamping fixtures, pressing tools and test rigs that need short cycle times at high pressure. Since displacement stays constant, downstream pressure valves take care of limitation. Operation is foreseen with HLP hydraulic fluid in an open circuit.
