The V20 2P8P 1A11 pump is manufactured by Vickers for the Square Vane Pumps series and serves hydraulic automation tasks that need a consistent supply. It is a vane pump with a displacement of 26.6 cm³ per revolution, which produces 8 US gpm at 1200 rpm and 100 psi. Right-hand clockwise rotation aligns with common prime movers, and the 1.25 NPT inlet thread lets it attach to standard suction plumbing. A sealed bearing supports the rotor to keep dirt out of the bearing grease, while a single-lip shaft seal limits external oil leakage. The pressure section is rated for continuous duty up to 172 bar, allowing the pump to drive moderate-pressure actuators without derating.
Design code 11 identifies the internal configuration so spare parts stay interchangeable. An inlet vacuum limit of 5 inHg guards against cavitation, and a maximum inlet pressure of 0.7 bar (10 psi) protects the shaft seal on flooded installations. Mounting with the body port at twelve o’clock eases hose routing when the outlet must point upward. The outlet is threaded 0.750 NPT and sits opposite the inlet, creating a straight-through flow path that reduces turbulence. This port orientation combines with the clockwise rotation to simplify line layout in compact manifolds, completing the hydraulic profile needed for automated machinery that uses Square Vane Pumps.
