Eaton Vickers PVQ45 Hydraulic Pump provides precisely controlled variable flow for open-circuit hydraulic systems that have heavy duty applications. An inline axial piston pump offers geometric displacement of about 45.0 cm³/rev and is capable of operating at pressures up to 190 bar, according to the particular model number and fluid used.
Variable displacement of the PVQ45 provides adequate flow according to the needs of the machine. When the system pressure reaches the preset level, the pump automatically decreases its displacement and does not supply excessive flow. This action enables reducing the power consumption, maintaining oil temperature and preventing additional strain on the hydraulic system.
Reduced noise generation is another main characteristic of the Eaton Vickers PVQ Series pump. The PVQ45 features balanced rotating assembly and precise machining of the internal elements, which eliminates pressure pulsations, vibrations and noise of the pump. Such pump construction makes it well-suited for use in power units, machine tools, presses, plastic processing equipment, production and handling systems.
PVQ45 could have been designed using pressure compensator, load sensing or both pressure and flow control systems. Eaton Vickers had a range of shafts, mountings, ports, pressures, and rotation available on different PVQ45 models. Certain models may be fitted with a through-drive system which enables running of another hydraulic pump from the same drive unit.
Worn out PVQ45 could lead to slow actuator motion, unstable pressure, low productivity, abnormal noises, high oil temperature, or increased case drain flow. Oil contamination, clogged inlets, wrong oil viscosity and worn components are some of the causes that can lead to these symptoms. Inspection needs to involve piston group, cylinder block, valve plate, swashplate, bearings, seals, and control assembly.
Rexton Hydraulic offers sales, inspection, and repair services for Eaton Vickers PVQ45 hydraulic pumps. Please provide complete part number or a photo of your nameplate while placing an order. We will be able to determine the displacement, pressure control, mounting, shaft, rotation and ports of the pump.
