The 0513R15A7VPV16SM14FY pump is manufactured by Bosch Rexroth within the VPV Vane Pumps series for variable-flow hydraulic automation. It operates as a vane pump, and its variable-displacement open-circuit design adjusts flow in response to pressure changes. A nominal displacement of 16 cm³/rev establishes the reference capacity, while an actual displacement of 17.37 cm³/rev determines the precise volume of oil moved per revolution. A single-stage pressure regulator controls displacement so the unit maintains system pressure without external valves. Clockwise rotation when viewed from the shaft end aligns with standard motor couplings. An ISO 3019/2 metric four-bolt mounting flange simplifies attachment to common pump brackets, and a #16 SAE inlet port accepts large hoses to minimize suction losses.
When driven at 1750 rpm the pump delivers 7.57 GPM (28.6 L/min), supplying circuits that require a steady medium flow rate. A #12 SAE outlet port connects the pressure line, and a #8 SAE case-drain port returns leakage oil to tank to keep housing pressure low. The factory pressure preset of 500 psi provides a ready-to-use setting for test stands or machinery start-up, while the construction supports a maximum operating pressure of 2000 psi (140 bar) for heavier loads. Internal seals are protected by limiting case pressure to 10 psi, and reliable intake is maintained by restricting inlet vacuum to 6 in Hg (152 mm Hg).
