PVWW Series Pump
Variable Displacement Pump for Ultra Low-lubricity Applications.
The PVWW line of pumps provides excellent variable-displacement pumping with fluids with a high water concentration. The PVWW is available with a variety of control modules. PVWW open-loop, variable-displacement, axial-piston hydraulic pumps are uniquely designed for low-lubricity, low-viscosity applications, such as pumping water-based, and environmentally-friendly fluids. Available in three frame sizes and seven displacements, PVWW pumps allow for greater flexibility to selectively match pressure and capacity. With a variety of optional controls, the PVWW family of pumps provide easy field interchangeability.
