V20-1P11P-1C-11

The V20-1P11P-1C-11 pump belongs to the Square Vane Pumps series from Vickers and supplies hydraulic automation circuits with a steady, low-pulse flow. It is a vane pump that converts shaft torque into fluid movement through internal vanes, making it suited for machine tools and mobile equipment where consistent delivery is required. A displacement of 36.4 cm³ per revolution (2.22 in³ per revolution) sets the volume moved each cycle and establishes the baseline flow rate for a given speed. When driven at 1200 r/min under 100 psi, the pump delivers 11 US gpm (42 L/min), matching medium-duty actuator demands. Fluid enters through a 1.25 in NPT threaded suction port, a common pipe size that simplifies supply line selection in North American installations. The housing attaches with a 2-bolt SAE A flange, allowing quick interchange on motors or gearboxes that share this standard mounting face.

The unit tolerates system pressures up to 172 bar (2500 psi), enabling operation in presses, lifts, or steering circuits that need moderate force without oversizing components. A maximum speed rating of 2500 r/min permits coupling to electric motors running at typical synchronous speeds while keeping vane tip velocity within safe limits. Discharge oil leaves through a 0.75 in NPT outlet placed in line with the inlet port, so hoses can run parallel and reduce bends inside compact power packs. A single lip shaft seal, supported by a sealed bearing, retains fluid and keeps contaminants out of the bearing cavity, lengthening service intervals. Together these characteristics form a balanced specification set for installers seeking a reliable, flange-mounted source of hydraulic flow at controlled pressure and speed.
