The Bosch Rexroth PR4-3X/800-700RA01M08 (R901088960) is a high-quality radial piston pump designed for industrial applications requiring a reliable and efficient hydraulic power source. This robust pump features a cast iron housing, ensuring durability and long service life, and operates with NBR seals suitable for standard hydraulic fluids like HLP. With its constant displacement design, the PR4-3X/800-700RA01M08 maintains consistent flow rates, critical for machinery requiring steady hydraulic pressure.
This model has a maximum operating pressure of 700 bar and a maximum displacement of 800 cm³, making it an excellent choice for demanding applications. The pump operates at a minimum speed of 600 rpm and can reach up to a maximum speed of 1800 rpm, providing flexibility in system design and application. It offers multiple pressure ports that allow for various cylinder combinations, enabling precise customization to meet specific requirements.
The PR4-3X/800-700RA01M08 is designed with hydrodynamically lubricated plain bearings that contribute to its extended service life. Its self-priming nature and valve-controlled operation ensure reliable performance even in rigorous conditions. The direction of rotation is clockwise when viewed from the shaft end, which should be considered during installation.
The internal mechanism consists of an eccentric shaft that drives the pistons arranged radially around it. As the pistons move within their cylinders due to the eccentric motion, they draw in fluid during their downward stroke and expel it during the upward stroke through valve-controlled suction and discharge processes.
With its fixed displacement feature and robust construction, the Bosch Rexroth PR4-3X/800-700RA01M08 radial piston pump is well-suited for industrial settings where steady hydraulic flow is essential for optimal machinery operation. Its thoughtful engineering ensures efficiency and reliability in open circuit systems across various applications.

Under no circumstances may drain and returning fluid be drawn directly into the suction port again, i.e., select the largest possible distance between suction line and return line. The return drain must always be below the oil level. Ensure suction-tight installation of the pipes.
No radial or axial forces permissible on the pump drive shaft! Motor and pump must be exactly aligned! Always use a coupling that is suitable for compensating for shaft offsets! When installing the coupling, avoid axial forces, i.e., when installing, do not hammer or press the coupling onto the shaft! Use the female thread on the drive shaft.
