The V20-1P13S-1A11 hydraulic pump belongs to the Square Vane Pumps series from Vickers and supplies pressurized fluid for industrial automation circuits. Its standard D cover establishes the internal flow passages used across general duty systems. A displacement of 42.5 cm³ per revolution allows the pump to move 13 US gpm at 1200 rpm, matching moderate flow requirements. The casing withstands up to 152 bar operating pressure, enabling it to drive cylinders that demand substantial force. A ceiling speed of 2400 rpm supports direct coupling to high-speed electric motors. Clockwise shaft rotation integrates with right-hand drives, while a 0.750-inch shaft diameter and a 0.1875 inch by 1.62 inch key provide a rigid, slip-free mechanical connection.
Hydraulic fluid enters through a 1.25-inch NPT inlet, and inlet pressure must stay below 0.7 bar to protect the shaft seal; the pump also tolerates up to 5 inHg vacuum so it can draw from reservoirs mounted below. Flow exits by way of a 1.062-12 UN-2B SAE O-ring outlet located opposite the inlet, keeping suction and discharge lines separated for easier plumbing. A two-bolt SAE A flange secures the unit, and the 3.250-inch pilot centers it precisely on the prime mover to reduce misalignment wear. Combining these port, mounting, and suction limits prevents cavitation and simplifies maintenance within automated hydraulic machinery.
