V20-1P6S-1A11-LH

The V20-1P6S-1A11-LH pump belongs to the Square Vane Pumps series produced by Vickers for hydraulic automation systems that require steady, low-volume fluid delivery. As a vane pump, it develops flow by sweeping oil between rotor vanes and a cam ring, and the ring capacity of 6 GPM supports compact presses, machine tools, and auxiliary circuits. A counter-clockwise rotation when viewed from the shaft end lets the unit match left-hand drive arrangements, while the inlet port is a 1.25 in NPT thread so installers can connect common schedule-pipe fittings without adapters. Discharge is arranged opposite the inlet port, which simplifies hose routing in tight manifolds and helps separate suction and pressure lines.

A 2-bolt SAE-A flange mounts the pump securely on standard motor pads, reducing alignment time and ensuring shaft concentricity under vibration. The standard cover encloses the cartridge to protect internal vanes and maintain pressure balance, and design code 11 identifies the specific geometric revision used for spare-part matching. Fluid containment relies on a standard seal at the housing interface, while a single-lip shaft seal paired with a sealed bearing prevents external leakage and keeps contaminants away from the bearing race during continuous duty.
