PVK Series Pump
Variable Axial Piston Pump with Longitudinal Controls
The PVK pump line consists of three sizes of variable-displacement, open-loop, axial-piston pumps. The PVK is unique from other variable pumps because it has longitudinally-mounted controls.
It is recommended that legacy PVK pumps be replaced by the current PVG pump line.
Available in two frame sizes and three displacements, PVK pumps feature advanced “hard-on-hard” rotating system that provides longer operational life, resistance to contamination, and allows for operation with low-viscosity or other special fluids. It has a unique hydrodynamic bearing support on the cylinder barrel contributing to the pump’s compact design. The PVK is also available in a fixed-displacement version, known as the PFK.
