The V2020-1F8S8S-11AB30 hydraulic pump belongs to the Square Vane Pumps series from Vickers and is intended for hydraulic automation circuits that demand compact double pumping in a single housing. It is built as a double configuration, so a cover-end and a shaft-end section share one drive to supply separate flow paths. The right-hand, clockwise shaft rotation matches standard engine drives, while the 2-Bolt SAE B mounting interface enables direct coupling to common power take-off pads. Fluid enters through an SAE 4-bolt 2.00 in flange inlet port, and it exits through two dedicated outlets: No. 1 uses a 1-1/16-12 UN-2B thread and No. 2 uses a 1-1/16-12 straight thread. The No. 2 outlet is positioned 90° counter-clockwise from the inlet at the AB location, simplifying manifold routing. The assembly weighs 35 lb, which allows manual handling during equipment service.
Hydraulic output is defined by separate displacements for each pumping section; the shaft-end produces 26.6 cm³ per revolution for a rated flow of 8 US gpm, and the cover-end delivers 36.4 cm³ per revolution for a rated flow of 11 US gpm. Continuous duty is supported up to 172 bar (2500 psi) of operating pressure, giving the pump a broad working range for machine tools and mobile equipment. The shaft-end can run at speeds to 2800 rpm, while the cover-end is limited to 2500 rpm to protect vane integrity. An internal flow-control and relief valve moderates circuit pressure and diverts excess oil, reducing the need for external valving. These performance limits ensure stable flow under varying load demands.
