The V10 1P7P 1A20 LH vane pump is produced by Vickers as part of the Square Vane Pumps series. It supplies regulated hydraulic flow for automated actuators and control valves. With a displacement of 22.8 cm³ per revolution, the unit provides a SAE rated capacity of 7 US gpm at its nominal running point. Left-hand counterclockwise rotation matches power trains that drive from the opposite side, and the outlet sits 90 degrees clockwise from the inlet to streamline hose routing. A two-bolt SAE A flange secures the pump directly to motor face adapters, while a 1-inch NPT thread on the inlet port accepts standard suction piping. Torque is delivered through a 0.750-inch shaft that carries a 3/16-inch square key, and a cast-iron housing withstands mechanical stress and abrasion.
Operating limits define its application envelope. The pump tolerates continuous pressures up to 138 bar, enabling service in medium-pressure power units, and it maintains reliable flow at speeds as high as 2800 rpm. Suction integrity is preserved by restricting inlet vacuum to 5 inches of mercury, while a supercharge allowance of 10 psi lets designers flood the inlet when needed. Buna-N seals contain petroleum-based fluids across normal temperature ranges and resist common additives. The complete assembly weighs 15 pounds, so installation can be completed without lifting equipment. These parameters protect the vanes from cavitation, keep internal leakage low, and support long service intervals in automated hydraulic systems.
