Eaton Vickers PVQ20 Hydraulic Pump allows a varying output of hydraulic fluid to open-circuit industrial applications needing reliable and silent operations. Its inline axial-piston design features geometric displacement of 21.1 cm3/rev as well as maximum allowable pressure of 210 bar. This pump is ideal for compact machinery and hydraulic power units with smooth working and controlled flow conditions.
As for the operation of the PVQ20, this device adjusts its displacement in accordance with real needs of the system. PVQ20 is able to cut down flow in idle and light load modes while increasing delivery when actuators need hydraulic power. This allows to avoid any unnecessary flow of oil.
Industrial applications may include machining equipment, packing machines, hydraulic presses, production machinery and power units. The compact design of the pump allows installing the pump in machines where there is not much free space. The quiet running characteristics of the pump allow using it in manufacturing processes where the operator works near to the hydraulic machinery.
The performance of pumps is directly influenced by the quality of the hydraulic fluid. Clean oil, the right viscosity and proper filtering of the fluid should be ensured. In addition, it will be prudent to check if there is any restriction, air leakage or improper sizing of the inlet line since poor inlet conditions can lead to problems such as cavitation, unstable flow and damage of the internal piston assembly.
If a pump has worn out, the operator will experience low flow rates, variable pressures and low speeds of operations. Other indications of wear are noisy operation, excessively high oil temperatures and leakage at the shaft or controller. However, before concluding that the pump is faulty, one should investigate filters, valves and pressures.
At Rexton Hydraulic, we service and supply aftermarket Eaton Vickers PVQ20 pumps for various machines. We look into the model code and the requirements before offering replacement or repair solutions.
