Axial piston pump

  • 29-Jun-2010 01:47 EDT


Bosch Rexroth has redesigned the high-pressure variable pump A4VG for closed circuit applications. With increased power density, the Series 40 helps mobile equipment manufacturers comply with stricter emissions regulations. The nominal pressure of the series has increased to 6500 psi (450 bar), and nominal parameters can counteract the reduced speed of the diesel engine and lower input flow rates. Nine nominal parameters provide a modular range of control units and enable a choice in axial piston pump with swashplate design for any application. The redesigned, flexible pump case can include various sensors, such as monitoring swivel angle, high pressure, and rotational speed. A bowl-shaped design avoids high-pressure transitions at sealing points. Rexroth also relocated the high-pressure ports to optimize arrangement of the hydraulic lines. If service is required, the series uses connections for the O-ring seals to ensure all threads are leak-tight.
