    Description

    Bosch Rexroth PR4-3X series pumps are fixed displacement radial piston pumps.

    The pump is available in 14 sizes: 50 | 100 | 150  | 200 | 250 | 300 | 350 | 400 | 450 | 500 | 550 | 600 | 650 | 700 cc/rev.

    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.

    Other features of the Bosch Rexroth PR4-3X include:

    • Maximum operating pressure 700 bar
    • Long service life due to hydro-dynamically lubricated plain bearings
    • Several pressure ports with different cylinder combinations
    • Self-priming, valve-controlled
