The 2520VQ17A14 11AA 20L is part of the VQ Thru-Drive Vane Pumps series from Vickers and supplies hydraulic power for automated machinery. Design code 20 fixes its internal options for direct interchange within the series. Left-hand (counter-clockwise) rotation lets designers align the prime mover on the opposite side of standard right-hand frames. A shaft-end displacement of 55.2 cm³ per revolution provides 17 US gpm at 1200 rpm and 100 psi, delivering the primary flow needed for medium-duty circuits. Ten vanes share radial forces evenly, which lowers vibration and extends bearing life. The unit tolerates inlet pressures up to 1.4 bar, so boosted suction can be used without exceeding seal limits.
The cover end moves 45.9 cm³ per revolution and produces 14 US gpm at 1200 rpm and 100 psi, allowing a secondary circuit to run from the same housing. A maximum inlet vacuum of 5 inHg keeps net positive suction head above the cavitation threshold when reservoirs sit below the pump. Outlet O1 is opposite the inlet, while outlet O2 is positioned 135° counter-clockwise from the inlet, giving line builders two angled discharge paths without extra fittings. Inlet, O1, and O2 all use an SAE four-bolt flange, which speeds removal and replacement. These porting features, combined with thru-drive capability, let a single shaft support multiple pump sections in compact automation layouts.
