PVQ(Eaton PVQ) series hydraulic variable pump

Introduction

- HWPVQ 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.

- HWPVQs 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 HWPVQs

- 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.

- Many HWPVQ 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 HWPVQs have excellent operating characteristics, and the pumps many control and mounting options allow choosing the optimum model for any application. Additionally, HWPVQs possess the same durability and long life characteristics expected of the best industrial products in today’s marketplace.
