Nominal displacement: 50 mL/r (The "50" in "E550" usually indicates that the nominal displacement is 50 milliliters per revolution).
Rated pressure: Generally around 16 MPa, which may vary slightly among different manufacturers.
Maximum pressure: Usually up to around 20 MPa.
Rated speed: Approximately 1500 r/min. This is a suitable speed under rated operating conditions.
Volumetric efficiency: Not less than 90%. That is, under normal working conditions, the ratio of the actual output flow to the theoretical flow is relatively high.
Overall efficiency: Generally around 80% - 85%, which reflects the comprehensive efficiency of the oil pump in converting input power into output hydraulic power.
Drive method: Usually, it can be driven by various power sources such as electric motors and diesel engines through couplings and other means.
Oil viscosity range: The suitable oil viscosity is generally between 17 - 37 mm²/s. The oil pump can work well within this viscosity range to ensure performance and efficiency.
Oil temperature range: The normal operating oil temperature range is generally from -20°C to 80°C. Exceeding this range may affect the performance and service life of the oil pump.
