The F3 V20 1P9P 1C11 pump is produced by Vickers and is part of the Square Vane Pumps series, supplying hydraulic automation circuits with controlled flow and pressure. Fluid is displaced by a vane mechanism with a capacity of 29.7 cm³ per revolution (1.81 in³ per revolution). At 1200 rpm and 100 psi the pump delivers 9 US gpm, supporting moderate-speed machine functions. The drive shaft may turn at speeds up to 2800 rpm, a limit that sets the maximum permissible motor selection. Hydraulic oil enters through a 1.25 in NPT threaded inlet, and the porting is arranged so the 0.750 in NPT outlet is inline with the inlet in orientation C. Installation is completed with an SAE-A two-bolt flange, while clockwise rotation viewed from the shaft end matches common prime mover layouts.
A standard cover encloses the cartridge assembly and allows a flow of 75.0 L/min (19.8 gpm) when the shaft runs at peak speed and the system reaches rated pressure. Operating pressure can rise to 172 bar (2500 psi), and doing so requires 26.5 kW (35.5 hp) of input power from the prime mover. Viton seals resist hydraulic fluids and temperature cycling, and a single-lip shaft seal together with a sealed bearing keeps leakage and contamination risk low. Discharge fluid exits through the 0.750 in NPT port specified for the standard cover, completing the inline flow path. These characteristics combine to provide predictable performance where compact, fixed-displacement hydraulic sources are needed.
