Rexroth A4VSO Pump FAQ
The Rexroth A4VSO pump is designed for operation in open loop circuits for hydrostatic drives, where the flow is proportional to the input drive speed and displacement. The swash plate design allows for variable output flow by adjusting the swash plate angle.
The maximum operating pressure for the A4VSO pump is 350 bar (5100 psi), with a peak pressure of 400 bar (5800 psi).
The A4VSO pump is suitable for use with various hydraulic fluids, including mineral oil-based fluids and HF (high water content) fluids. Specific details on suitable fluids and their compatibility are provided in the documentation.
The recommended filtration level is to maintain fluid cleanliness of at least 20/18/15 according to ISO 4406. The use of efficient filtration systems is essential to ensure long pump life and reliable operation.
The A4VSO pump offers various control options, including pressure control (DR), pressure control for parallel operation (DP), flow control (FR), pressure and flow control (DFR), power control (LR), manual control (MA), electric motor control (EM), hydraulic control (HM), and electronic control (EO)o.
The dimensions and weight of the A4VSO pump vary depending on the size. For example, a size 40 pump weighs approximately 39 kg, while a size 1000 pump weighs around 605 kg. Detailed dimensional data is provided for each pump size in the documentation.
During and shortly after operation, the housing and especially the solenoid of the pump can become extremely hot. Suitable safety measures, such as wearing protective clothing, must be taken to prevent injuries.
