Type: Quiet, in-line, variable displacement axial piston pumps.
Displacement
The full PVQ pump series covers 7 displacements ranging from 10.5 cc/rev to 45.1 cc/rev, including models such as PVQ10, PVQ13, PVQ20, PVQ25, PVQ32, PVQ40, and PVQ45.
Flow Rate
For example, the PVQ10 has a geometric output flow of 18.9 l/min (5.0 gpm) at 1800 rpm, the PVQ20 has a flow of 38 l/min (10.0 gpm) at 1800 rpm, and the PVQ45 has a flow of 81.2 l/min (21.0 gpm) at 1800 rpm2.
Pressure Ratings
The operating pressures are up to 210 bar (3,045 psi)2.
Rotational Speed
The pumps typically operate at a maximum speed of 1800 rpm2.
Fluid Compatibility
Vickers PVQ pumps can operate with many types of hydraulic fluid, including water-content and phosphate ester fluids, as well as petroleum-based and synthetic fluids.
Control Options
Displacement is varied by means of pressure and/or flow compensator controls, offering a variety of control options for maximum operating flexibility.
Noise Level
The sound levels of these pumps are close to, or below, those of the electric motor driving them. The noise is reduced by a patented timing arrangement that also produces low pressure “pulses” in the outlet flow, making them suitable for applications where low noise is required.
Mounting and Configuration
Many pumps are available in a thru-drive configuration, allowing coupling to fixed and variable displacement pumps to form a compact and versatile package.
Weight
The weight of the pumps varies by model. For example, the PVQ10 weighs approximately 7.2 kg (16 lbs), and the PVQ20 weighs about 14 kg (31 lbs)2.
