Bosch Rexroth PR4 Series Radial Piston Pump
Bosch Rexroth PR4 pumps are valve-controlled, self-priming, radial piston pumps with constant displacement. The pistons are arranged radially to the eccentric shaft. In downward movements of the piston, the working space in the cylinder is enlarged. The resulting under pressure opens the suction valve and this establishes the connection from the suction chamber to the working space. In upward movements of the piston, the suction valve is closed and the pressure valve is opened. The hydraulic fluid now flows to the system via the pressure connection.
The PR4 3X series radial piston pump is available in the following sizes: 1.60-700, 2.00-700, 2.50-700, 3.15-500, 4.00-700, 5.00-500, 6.30-500, 8.00-500, 10.00-500, 16.00-500, and 20.00-500. The pump has a maximum operating pressure of 700 bar and a maximum displacement of 19.43 cm3.
Other features of the radial piston motor include:
- Fixed displacement;
- Range of 14 sizes;
- Long life cycle thanks to hydrodynamically lubricated plain bearings;
- Choice of pressure ports with different cylinder combinations.
