Model Designation: A10VSO 31 Rexroth Hydraulic Pump 18
Type: It is an axial - piston variable - displacement pump with a swash - plate design. This type of pump is typically used in open - circuit hydraulic systems for hydrostatic power transmission.
Performance Specifications
Displacement
The displacement of the pump is 18 cm³/rev. This indicates the volume of fluid that the pump can displace in one complete revolution of its shaft.
Pressure Ratings
Rated Pressure: The rated operating pressure is usually around 280 bar. This is the pressure at which the pump is designed to function optimally during normal operation.
Maximum Pressure: The pump can withstand a maximum pressure of up to 350 bar. However, continuous operation at the maximum pressure may lead to reduced component life and potential performance issues.
Speed
Maximum Rotational Speed at Maximum Displacement: At its maximum displacement, the maximum rotational speed of the pump is approximately 3,000 rpm. This speed limitation is crucial to prevent over - speeding - related problems such as excessive wear, vibration, and decreased efficiency.
Allowable Maximum Rotational Speed with Reduced Displacement: When the displacement is less than the maximum, the pump can operate at a higher speed. The allowable maximum rotational speed in such cases can reach up to 3,600 rpm.
