The F3 V20 1P8S 1C11 pump belongs to the Square Vane Pumps series from Vickers and provides fixed-volume flow for hydraulic automation circuits. Its displacement of 26.6 cm³ per revolution yields a steady 30 L/min at 1200 rpm, supporting moderate actuator demand without flow controllers. Installation is handled by an SAE J744 101-2 two-bolt flange, and a 1.25 in NPT inlet admits reservoir oil directly to the cartridge assembly. The primary outlet is a .750-16 UNF-2B O-ring port located inline with the inlet, which simplifies rigid or flexible hose routing. Right-hand rotation couples to standard prime movers through a 0.750 in shaft, and overall dimensions of 7.84 in length, 5.12 in width, and 4.79 in height fit compact power units. The assembled mass is 18 lb, allowing one-person handling during installation or service.
The pump can be driven up to 2800 rpm while the vane geometry keeps internal leakage low and maintains volumetric efficiency. A continuous working pressure rating of 172 bar enables use in medium-pressure presses, molding equipment, and automated tooling. A dedicated 0.50 in NPT tank port returns case drain oil to the reservoir to prevent housing overpressure and extend seal life. Flow rises proportionally with shaft speed, so designers can size valves and heat exchangers for the higher volume available at maximum rpm. These operating limits define a clear envelope for reliable duty in industrial or mobile hydraulic systems.
