A4VTG71 and A4VTG71HW: The nominal displacement is approximately 71 cm³/rev. As variable displacement pumps, they can adjust the displacement within a certain range according to the system's requirements, which is crucial for matching the flow demands of different hydraulic applications.
A4VTG90 and A4VTG90HW: The nominal displacement is around 90 cm³/rev. Similar to the 71 series, these pumps can vary their displacement to optimize performance in the hydraulic system.
Operating Pressure
Rated Pressure: These pumps are typically designed to operate at a rated pressure in the range of 350 bar (35 MPa). This rated pressure allows them to provide stable and reliable performance for driving hydraulic actuators in various applications.
Peak Pressure: They can usually withstand a peak pressure of up to around 400 bar (40 MPa) for short periods. This enables the pumps to handle sudden pressure surges that may occur during the operation of the hydraulic system.
