Radial Piston Pump PR4-3X/16,00-500RA01M01 - Bosch Rexroth R901089290

Mounting decides whether a high-pressure pump fits an existing machine. The PR4-3X/16,00-500RA01M01 sits on a 4-hole fastening with 63 mm centering, is driven through a cylindrical shaft Ø 25 mm with fitting key to ISO 3019-2 and delivers a maximum of 500 bar at up to 22 l/min.

Benefits

• 4-hole fastening, 63 mm centering and a shaft end to ISO 3019-2 as a defined interface to the drive.
• Maximum operating pressure of 500 bar at a constant displacement of 16 cm³.
• Up to 22 l/min in an open circuit with HLP hydraulic fluid.
• Ten pistons produce an even delivery flow across the revolution.
• 16.6 kg cast iron housing with NBR seals.

Applications

The pump is used where an existing power unit gains a high-pressure branch, for example on clamping systems, presses and hydraulic nuts. As there is no through-drive, it is fitted as the final unit on the motor. Direction of rotation is clockwise.
