The V20-1S13S-62B11L pump belongs to the Square Vane Pumps series manufactured by Vickers and provides fixed-displacement flow for automated hydraulic systems. It moves 42.5 cm³ of fluid per revolution, defining the volume transferred with each shaft turn. At 1200 rpm and 100 psi it supplies 13 US gpm, ensuring stable circuit throughput under normal plant pressure. The casing tolerates 152 bar (2200 psi) so the unit can operate in medium-pressure lines found in presses and tooling machines. A maximum speed of 2400 rpm permits higher flow when the drive motor is run faster. Left-hand rotation matches drive trains where the shaft turns counterclockwise. A 2-bolt flange mounting pattern secures the housing to standard motor or bracket faces. The outlet port sits 90° counter-clockwise from the inlet, simplifying tube bends in square power units, and the port is threaded 1.062-12 UN-2B to accept common straight-thread adapters.
The internal ring is designated size 13, matching the rotor diameter so volumetric leakage stays low at the rated pressure. Twelve vanes sweep the ring bore to deliver continuous flow with reduced ripple. Buna-N sealing elements are used to withstand petroleum-based hydraulic oil and moderate temperatures. Overall dimensions of 4.79 in height, 5.12 in width, and 6.77 in length let the pump fit into compact reservoirs while leaving service clearance around fittings. A weight of 18 lb allows one technician to position and fasten the assembly without lifting equipment. These construction details support dependable operation across the specified speed and pressure range while keeping installation and maintenance straightforward.
