V20F 1P13P 3B8G22

The V20F 1P13P 3B8G22 vane pump is produced by Vickers in the Vane Pumps series and provides regulated hydraulic flow for automated machinery. Its displacement of 42.5 cm³ per revolution determines the volume transferred each shaft turn and forms the basis for flow calculations. Right-hand clockwise rotation aligns with standard electric-motor drives, avoiding coupling inversions. A 2-bolt SAE A flange supports direct mounting to common pump pads, keeping installation compact. The 1-1/4 NPTF inlet port handles large suction lines, and the outlet is set 90° counter-clockwise from the inlet to streamline hose layout in confined panels. A flow-control cover with an internal relief section combines metering and pressure protection inside the housing, reducing the need for external valves.

The internal flow circuit is preset to deliver 8 US gpm, maintaining consistent actuator speed when prime-mover speed fluctuates. Under test conditions the unit reaches a rated capacity of 13 US gpm at 1200 r/min and 100 psi, which reflects performance without flow restriction. The pump withstands working pressures up to 152 bar, letting it drive medium-pressure cylinders and motors. An integrated relief valve vents at 121 bar to prevent downstream overloads. Design code 22 identifies the exact build revision so service parts and seal kits match dimensional changes introduced in that iteration.
