The V2010 1F9S2S 11AA12L belongs to the Square Vane Pumps series and is manufactured by Vickers for hydraulic automation systems that need two discrete flow sections in one unit. A 2-bolt SAE B flange mount secures the pump directly to standard prime movers, while a 4-bolt flange inlet maintains a rigid, high-pressure seal on the suction side. Internal passages place port #2 at 135° counter-clockwise from the inlet and port #1 directly opposite, which simplifies hose routing in compact power packs. Counter-clockwise rotation viewed from the shaft end aligns with common industrial motor direction, and a working limit of 172 bar (2500 psi) allows the housing to support medium-pressure circuits. The assembly weighs 13.6 kg (30 lb), light enough for one-person installation. Drive torque is carried by a 0.873-inch major diameter spline with 13 teeth, ensuring secure power transfer under continuous duty.
At the cover end, the pump displaces 6.6 cm³ per revolution (0.40 in³/rev) and delivers a rated flow of 2 US gpm; this section can operate at speeds up to 3000 rpm to supply small actuators quickly. The shaft end increases displacement to 29.7 cm³ per revolution (1.81 in³/rev) so it can provide 9 US gpm for larger loads, though its speed is limited to 2800 rpm to control bearing stress. A 0.750-16 UN-2B straight-thread outlet on the cover end matches standard SAE adapters for leak-free pressure lines, whereas the shaft end uses a 1.0625-12 UN-2B thread to accommodate the higher flow path. These outlet sizes, combined with the dual-section flow ratings, let designers drive multiple circuits from a single pump without adding extra motors or frames.
