The A10VSO 32 Rexroth Hydraulic pump 45 is a high - performance hydraulic pump. It belongs to the axial piston variable displacement pump category with a swash - plate design. This pump is mainly used in open - circuit hydraulic systems for hydrostatic power transmission.
Performance Specifications
Displacement
The nominal displacement of this pump is 45 cm³/rev. This value determines the volume of fluid displaced per revolution of the pump shaft and is a crucial factor in calculating the flow rate.
Pressure Ratings
Rated Pressure: The pump has a rated pressure of typically around 280 bar. This is the normal operating pressure under which the pump is designed to work efficiently and reliably over an extended period.
Maximum Pressure: It can withstand a maximum pressure of up to 350 bar. However, operating at the maximum pressure for prolonged periods may affect the pump's lifespan and performance. The pressure limits are important for ensuring the integrity of the pump and the safety of the hydraulic system.
Speed
Maximum Rotational Speed at Maximum Displacement: The maximum speed of the pump when operating at its full displacement is approximately 2,600 rpm. This speed limit is set to prevent over - speeding and associated mechanical failures such as excessive wear, vibration, and reduced 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 3,100 rpm. The ability to vary the speed depending on the displacement allows for flexibility in the operation of the hydraulic system to match different load requirements.
