VANE PUMP Vane Pump Design: A Vane Pump is a Positive Displacement Pump (PDP) with a vaned rotor that is positioned off-center within a cylindrical chamber. The vanes slide in and out as the rotor turns. Pumping action is caused by the volume changes in between blades. Advantages: Positive displacement, can handle low viscosities. Application: Transmissions, hydraulics, fluid transfer. PumpLinx: Solve Flows, Pressures, Cavitation, and Loads: Discriminators: Models cavitation Accurate tip leakage Superior treatment of rotating-stationary interfaces Ease-of-use Fast turn-around Design Issues/Benefits: Rotor Design Port design Leakage reduction Reduce Cavitation effects on efficiency and pump life Reduce Pressure ripple and noise

EXAMPLE: Vane Oil Pump Optimization of metering grooves and ports for an automotive oil pump.
