The V20 1S13S 38C11 063 vane pump belongs to the Square Vane Pumps series and is built by Vickers for hydraulic automation where a compact fixed-displacement source is required. A standard cover protects the cartridge assembly while maintaining interchangeability within the series. Displacement is 2.59 in3/rev, which sets the volume delivered for each shaft turn. Rated delivery reaches 13 US gpm at 1200 rpm and 100 psi, providing predictable flow to cylinders and motors. The pump can run up to 2400 rpm so it may couple directly to common electric motors. A ring-rotor rating of 3000 psi defines the maximum working pressure the internal parts can withstand. Clockwise rotation viewed from the shaft end specifies drive orientation, and a 2-bolt SAE-A flange supplies a standardized mounting face for equipment frames.
The inlet port is tapped 1.625-12 UN-2B so standard SAE suction fittings can be attached without adapters. Discharge fluid exits through a 1.062-12 UN-2B threaded outlet port that supports pressure lines sized for the stated flow. Both ports are inline, reducing hose runs and minimizing pressure loss in compact power units. A single lip seal combined with a sealed bearing prevents external leakage and blocks contaminants from reaching the shaft journal. Power is transmitted through a 16/32 DP, 11-tooth spline cut at a 30° pressure angle, delivering smooth torque transfer to the drive motor. The spline minor diameter of 0.590 in establishes the minimum bore in the mating coupling and ensures proper fit with standard SAE splined shafts.
