Eaton Vickers PVQ pump Hydraulic Vickers pump PVQ10, PVQ13, PVQ20, PVQ32, PVQ40, PVQ45 Description Operating pressure up to 210 bar (3000 psi) Control type with compensator control “C” or “CM”, etc. Displacement from 10, 5 to 45 cm3/r (0.64 to 2.75 in3/r) Speed up to 1800 r/min PVQ piston pumps are in-line, variable displacement units and are available in nine sizes. Displacement is varied by means of pressure and/or flow compensator controls.

An impressive assortment of control options offers maximum operating flexibility. PVQ operate at quietness levels that meet today’s demanding industrial conditions. The sound level of each unit approaches or is below that of the electric motor driving it. Sound is reduced by a patented timing arrangement that also produces low pressure “pulses” in the outlet flow. This leads to reduced tendencies for noise in systems using PVQ. The PVQ series is capable of operating with many types of hydraulic fluid. Water-content and phosphate ester fluids can be accommodated, in addition to the typical petroleum based and synthetic fluids.

Vickers ™ ® A2 EATON PVQ Piston Pumps Catalog Table of Contents -EN-0801. PVQ piston pumps are in-line, variable displacement units and are available in nine sizes. Displacement is varied by means of pressure and/or flow compensator. Assist initial priming, manual adjustment control setting must be at least 40% of maximum.

Many PVQ pumps are available in a thru-drive configuration to accommodate a multitude of application and installation requirements. Thru-drive models can be coupled to various types and sizes of fixed and variable displacement pumps, resulting in a compact and versatile package.

Such a package offers lower installed cost by reducing the installation size and by requiring only one mounting pad on the prime mover. Quiet PVQ have excellent operating characteristics, and the pumps’ many control and mounting options allow choosing the optimum model for any application.

Maximum pump delivery is maintained to approximately 3,4 bar (50 psi) below the pressure setting before being reduced.

The pressure compensator control operates on one side of center and has an adjustment range as designated in the model coding. Pressure Compensator with Adjustable Maximum Displacement Stop “D” The adjustable maximum stop pressure control enables the maximum pump delivery to be externally adjusted from 25% to 100% while maintaining all of the standard features of a pressure compensated pump. To assist initial priming, manual adjustment control setting must be at least 40% of maximum flow position. Remote Control Pressure Compensator “CG” Exactly the same as the “C” (pressure compensation option) except the machine operator is able to change the compensator setting through the use of a remote pilot relief valve, such as Vickers C-175. Requirements of the system at either of two preselected operating pressures. Maximum pump delivery is maintained to approximately 3,4 bar (50 psi) below either pressure control setting before being reduced.

Control type and pressure range are designated in the model code. Electric Dual Range Pressure Compensator “CD” The dual range pressure compensator control automatically adjusts pump delivery to maintain volume. Load Sensing & Pressure Limiting Compensators This compensator provides load sensing control under all pressure conditions up to the desired maximum.

It automatically adjusts pump flow in response to a remote pressure signal and maintains outlet pressure at a level slightly above load pressure. The integral pressure limiter overrides the load sensing control, reducing pump displacement as the preset maximum operating pressure is reached.
