Eaton Vickers V20 Hydraulic Pump

Eaton Vickers V20 Hydraulic PumpThe Eaton Vickers V20 Hydraulic Pump is known for its efficient and reliable performance when providing fixed-displacement flow for open-circuit applications. The pump is a balanced vane pump with capacities ranging approximately from 6 to 13 US gallons per minute, based on the displacement option chosen.

As a balanced vane pump, the V20 dispenses a specific quantity of hydraulic fluid in every rotation of its shaft. Therefore, the output capacity of the pump varies with the speed at which the pump operates. This feature makes the V20 appropriate for machinery requiring a constant supply of hydraulic fluid without having to use a variable-displacement pump.

The balance design in the pump minimizes the effects of hydraulic pressure within the pump’s working area by limiting any additional loading of the pump’s shaft and bearings, thus minimizing vibrations. Clean oil, correct viscosity, and free inlet flow are necessary.

Due to their different cover designs, the V20 can serve a wide variety of circuit applications. Depending on the specific design, the pump might employ standard covers, flow control covers or priority valve configurations. There are also various differences regarding shaft design, mounting flanges, port positions and direction of rotation.

The most common applications for this type of pump include steering circuits, hydraulic power units, machine tools, agricultural machines, material handling machines, lifts and auxiliary hydraulics. Finding the right version is more complicated than just finding a pump belonging to the V20 series family since the installation and control characteristics may be quite different.

A defective V20 may lead to poor flow rates, low system pressure, low responsiveness, odd sounds, overheating and shaft sealing issues. Clogged fluid, insufficient suction flow, wrong oil viscosity and damaged vanes or cam surface may produce such symptoms. The cover assembly, pressure plates, shaft, bearings, housing and seals must also be inspected.

Rexton Hydraulic offers testing, sales and service of Eaton Vickers V20 hydraulic pumps. Provide the full nameplate model number or an image of the nameplate prior to ordering. Our experts will help you determine your pump's rating, cover type, shaft, mounting, port positions before suggesting repair or new pump.
