The 20V5A 1A22R pump is manufactured by Vickers for the V Series Vane Pumps series and supplies hydraulic actuators with consistent flow in industrial automation. It displaces 18 cm³ per revolution, allowing moderate output while limiting power draw. At 1200 rpm and 100 psi it provides a rated capacity of 18 US gpm, matching common machine-tool and press requirements. Operating speed can be set between 600 and 1800 rpm so integrators can tune flow to demand. A maximum continuous pressure of 207 bar supports medium-pressure circuits, while the inlet side must not exceed 1.4 bar to protect shaft seals. Clockwise rotation is specified for correct shaft loading in standard right-hand drive trains. During operation at 1200 rpm and 2000 psi the sound level measures 62 dB(A), which assists plants in meeting noise control targets.
Fluid connection is straightforward because both inlet and outlet ports use SAE four-bolt flanges, and the outlet is positioned opposite the inlet to simplify rigid pipe runs. All port threads are inch-based so the pump mates with North American fittings without adapters. Power is transmitted through a 22.23 mm shaft that carries a 9.53 mm wide key, giving reliable torque transfer to electric or diesel prime movers. The internal cartridge employs a vane mechanism that maintains pulse-free flow at varied speeds, keeping actuators stable under changing loads. When mounting, designers can reference the flange orientation to keep the clockwise shaft consistent with the specified outlet location.
