EATON Vickers Q Series Piston Pumps Catalog V-PP-MC-0002-E December 2002 2 Introduction

PVQ piston pumps are in-line, variable displacement Many PVQ pumps are available in a thru-drive units and are available in nine sizes. Displacement is configuration to accommodate a multitude of applica- varied by means of pressure and/or flow compensator tion and installation requirements. Thru-drive models controls. An impressive assortment of control options can be coupled to various types and sizes of fixed and offers maximum operating flexibility. variable displacement pumps, resulting in a compact and versatile package. Such a package offers lower PVQs operate at quietness levels that meet today’s installed cost by reducing the installation size and by demanding industrial conditions. The sound level of requiring only one mounting pad on the prime mover. each unit approaches or is below that of the electric motor driving it. Sound is reduced by a patented Quiet PVQs have excellent operating characteristics, timing arrangement that also produces low pressure and the pumps’ many control and mounting options “pulses” in the outlet flow. This leads to reduced allow choosing the optimum model for any appli- tendencies for noise in systems using PVQs. cation. Additionally, PVQs possess the same durability and long life characteristics expected of the best The PVQ series is capable of operating with many industrial products in today’s marketplace.
