Eaton Vickers PVQ32 Hydraulic Pump

Eaton Vickers PVQ32 hydraulic pump that ensures silent and efficient work and precise control of the hydraulic power in open-circuit systems. The pump works with variable displacement and allows controlling the volume of hydraulic power and does not waste extra energy. It ensures the geometric displacement of 32.9 cm³ per revolution of the shaft.

PVQ32 is the pump with an inline axial-piston design, and it changes its displacement depending on the demands of the system. It is possible to use pressure compensator and flow-control modes that will decrease the volume of the output if the required pressure is reached in the circuit. Such work allows decreasing the amount of heat generated by the pump and wasting extra energy compared with the fixed displacement pump.

Eaton Vickers paid a lot of attention to the noise level in the process of creating PVQ series. The balanced design of the elements helps to control vibrations and pressure pulsations. These properties make the pump the convenient option for hydraulic power units, machine tools, manufacturing machinery, material handling equipment and other systems.

The pump is capable of withstanding a maximum pressure of about 140 bar, according to the complete model code, operating conditions and hydraulic fluid. Possible variants will vary depending on the configuration of the controls, mounting flanges, shafts, port connection and direction of rotation. In some models it will be possible to implement through-drive design to install another pump. The selection of these parameters is important because two PVQ32 pumps can have similar appearance, but different inner and installation configurations.

The most common causes of the PVQ32 wear are pressure drop are slow actuator operation, flow instability, strange noises, overheating, and increased case drain flow. Contamination of hydraulic oil, improper viscosity of oil, insufficient inlet flow or wear of piston group components can lead to these issues. Professional examination should involve the examination of rotating group, valve plate, swashplate, bearings, seals and control unit before making the choice about repairing or replacing the pump.
