V20 1P13R 1A11

The V20 1P13R 1A11 vane pump is produced by Vickers within the Square Vane Pumps series and supplies fixed-volume flow for hydraulic automation tasks. A displacement of 42.5 cm³ per revolution establishes the quantity of oil moved each shaft turn. The inlet port is 1-1/4 NPT, giving adequate area to admit fluid without undue velocity. A two-bolt flange mounting pattern secures the housing to motors or manifold faces with minimal hardware. The outlet port is located opposite the inlet in position A to keep suction and pressure lines separated for easier routing. When driven at 1200 rpm and 100 psi, the pump yields a rated flow of 13 US gpm (49 L/min), which serves as a baseline for moderate-duty circuits.

The unit tolerates a maximum operating pressure of 152 bar (2200 psi), letting it function in higher-load hydraulic loops. A maximum speed of 2400 r/min defines the upper rotational limit that bearings and vanes can accept. At this speed and full pressure, the pump typically delivers 25.9 US gpm (98.1 L/min), furnishing nearly double the baseline volume. Producing that flow demands about 39 hp (29.1 kW) of input power, information needed when selecting an electric motor or engine. These pressure, speed, flow, and power figures together outline the operating envelope of the V20 1P13R 1A11 for designers integrating vane pumps into automated machinery.
