Eaton Vickers PVE21 Hydraulic Pump is an axial piston pump delivering variable hydraulic flow for open-circuit mobile and industrial equipment. The pump has a geometric displacement of about 45.1 cm³ per revolution and can be used under the pressure of around 185 bar, depending on the specific code of the complete product.
PVE21 regulates its flow by changing the swashplate angle inside the pump. When increased hydraulic flow is needed, the pump increases its displacement. If the hydraulic flow demand is reduced or the pressure in the circuit reaches the selected value, the pump will lower its displacement. This will assist in controlling energy consumption, avoid oil heating and excessive mechanical stress on the hydraulic system.
The pump can be used for various equipment that needs to deliver pressure and variable hydraulic flow in different working conditions. Such applications may include construction, agricultural, material handling, utility, and industrial hydraulic power unit equipment. The compact design of the pump can be used to save installation space.
Depending on the specification, the Eaton Vickers PVE21 might be equipped with either pressure-compensator, load-sensing or other pressure-and-flow controls. Various models also have particular mounting flanges, shafts, ports, direction of rotation and pressure values. The through-drive setup enables operating another hydraulic pump from the same drive line, which is beneficial for equipment with several hydraulic functions.
Checking the entire identification number is a mandatory step when choosing a replacement for PVE21. Only partial matching of the pump series or its displacement results in selecting a wrong part. Incompatibility in such parameters as shafts, mounting pattern, control type, ports or direction of rotation makes installation impossible.
The malfunctioning pump leads to slower hydraulic actions, low pressure, unstable operation, strange noises, high oil temperature or leakage from case drain. This is caused from contaminated oil, insufficient flow rate, inappropriate oil viscosity and worn-out internal parts. The piston assembly, cylinder housing, valve plate, swashplate, bearings, seals and control section should be examined by technicians.
