V20 2P8P 1C11 LH

The V20 2P8P 1C11 LH vane pump is manufactured by Vickers as part of the Vane Pumps series and supplies pressurized fluid for hydraulic automation. It follows design code 11, indicating its internal feature set for interchangeability within the range. A displacement of 26.6 cm³ per revolution provides predictable volume output for proportional valve groups, while a maximum operating pressure of 172 bar allows operation in medium-pressure circuits. The rotor can run up to 2800 r/min, permitting responsive speed-controlled drives. Rotation is left-hand (counterclockwise), so the shaft must be driven in that direction. A priority valve cover is fitted to route flow to critical functions first, and the outlet is in line with the inlet (code C) to simplify straight-through manifold layouts.

The porting scheme supports straightforward plumbing: the primary outlet port uses a .750-16 UNF-2B thread for the main pressure line, the secondary outlet port is .875-14 UNF-2B for diverted flow, and the tank port matches the primary outlet thread at .750-16 UNF-2B to keep return fittings consistent. Under standard conditions the pump delivers a SAE rated capacity of 30 l/min (8 US gpm), matching typical actuator demands in mobile and industrial machinery. Standard thread sizes allow common SAE adapters, reducing installation time and leakage risk. The consistent port geometry complements the unit’s fixed 26.6 cm³/rev displacement so commanded flow is maintained across the operating speed range.
