VP Hydraulic Variable Displacement Vane Pump https://www.dxvanepump.com/product/vane-pump/vp-hydraulic-variable-displacement-vane-pump.html The VP series variable vane pump is a pressure-compensated variable vane pump, equipped with a pressure adjustment device and a flow adjustment device. Its output flow can automatically adjust according to load changes, enabling the output power to match the load's operating speed and magnitude. It features high efficiency, energy saving, safety and reliability. The VP series vane pumps are particularly suitable as the power source in hydraulic systems with volumetric speed control, such as metal cutting machines, pressure machinery, leather machinery, and hydraulic power units.
