The Bosch Rexroth PR4-3X/630-700RA12M12 (R901132571) is a high-quality radial piston pump designed for industrial applications requiring reliable hydraulic power in an open circuit control loop. This robust pump features a cast iron housing, ensuring durability and long service life, and operates with NBR seals suitable for HLP hydraulic fluids. With a constant displacement design, the PR4-3X/630-700RA12M12 delivers consistent performance and is capable of handling a maximum pressure of 700 bar.
This model has a fixed displacement size of 630 cubic centimeters and offers a maximum flow rate suited to its design specifications. The pump operates efficiently within its minimum and maximum speed parameters, ensuring optimal hydraulic response across various applications. The direction of rotation for this pump is clockwise when viewed from the shaft end, which must be considered during installation.
The PR4-3X/630-700RA12M12 is engineered with self-priming capabilities and valve-controlled operation that contribute to its ease of use and maintenance. It utilizes hydrodynamically lubricated plain bearings which significantly extend its service life by reducing wear. Additionally, this pump provides flexibility in system design through offering several pressure ports with different cylinder combinations, allowing for precise customization according to specific requirements.
Assembly of the Bosch Rexroth PR4-3X/630-700RA12M12 involves an eccentric shaft and multiple pump elements that work in unison to ensure efficient suction and displacement processes. This process allows for the smooth transfer of fluid through the system with minimal loss in performance. The weight and dimensions are tailored to integrate seamlessly into existing systems without necessitating extensive modifications.
In summary, the Bosch Rexroth PR4-3X/630-700RA12M12 radial piston pump stands out for its constant displacement feature, selfpriming operation, and compatibility with HLP hydraulic fluids, making it an excellent choice for industrial applications that demand high-pressure performance and reliability.

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.
