The V20 1S13S 38B11L063 pump is part of the Square Vane Pumps series manufactured by Vickers for hydraulic automation systems. Its displacement of 42.5 cm³ per revolution (2.59 in³/rev) delivers a fixed volume of oil each cycle, giving accurate speed control to actuators. A ring capacity of 13 US gpm supports moderate flow rates needed by machine tools and conveyors. The pump tolerates up to 152 bar (2200 psi), enabling it to drive cylinders and motors without overstressing the cartridge assembly. A maximum speed of 2400 rpm pairs well with common electric motor outputs and prevents overheating at higher drive ratios. Counter-clockwise rotation viewed from the shaft end aligns with left-hand power-train layouts and avoids reverse flow conditions. The two-bolt SAE A flange simplifies attachment to motor face plates, keeping shaft centers aligned under load. Sealed bearings exclude abrasive particles from the rotating group, lengthening service intervals in dusty factory zones.
The inlet port uses a 1.625-12 UN-2B thread so a large suction hose can be fitted with minimal pressure drop, while the outlet port features a 1.062-12 UN-2B thread that withstands full system pressure and secures rigid discharge tubing. The outlet is positioned 90° counter-clockwise from the inlet to keep hoses clear of adjoining components in compact power units. A single-lip shaft seal retains fluid at the drive end and limits leakage during pressure spikes. Physical dimensions of 8.460 in length, 5.120 in width, and 4.790 in height allow the pump to fit inside small hydraulic reservoirs and skid frames.
