The V20 1P11P 1C11 is produced by Vickers as part of the Square Vane Pumps series and provides consistent flow for hydraulic automation loops. It displaces 36.4 cm³/rev (2.22 in³/rev), delivering a rated flow of 11 US gpm at 1200 rpm and 100 psi. Shaft-end rotation is clockwise, and the assembly reaches speeds up to 2500 rpm without derating. A 2-bolt SAE A flange supports straightforward mounting to standard power units, while an inline outlet matches the 1.25 in NPT inlet port to simplify pipe routing.
The pump sustains working pressures to 172 bar (2500 psi) and accepts positive inlet pressure up to 0.7 bar (10 psi); vacuum on the suction side may reach 5 inHg for reservoir draw applications. Internal clearances are protected by a standard seal set, and the shaft uses a single-lip sealed bearing to control leakage and exclude contaminants. The vane pumping mechanism minimizes pulsation in closed-loop circuits and maintains orientation accuracy because the ports remain inline with the inlet connector.
