The V20F-1P13P-38C12H-22R is produced by Vickers in the Vane Pumps series and supplies hydraulic flow for automated actuators and valves. Its fixed displacement of 42.5 cm³ per revolution (2.59 in³/rev) determines the volume moved each shaft turn, while a controlled flow of 12 US gpm keeps circuit speed predictable under steady load. SAE-rated capacity reaches 13 US gpm at 1200 r/min with 100 psi, offering a benchmark for sizing drive motors. The unit can rotate up to 2400 r/min without exceeding bearing limits, and it tolerates system pressures as high as 152 bar (2200 psi) to suit medium-pressure machines. A factory relief setting of 140 bar (2000 psi) opens when pressure spikes, shielding hoses, seals, and cylinders from overload.
A 1-1/4 NPT inlet port accepts suction lines, and pressure oil exits through a 3/4-16 UNF O-ring boss outlet. The outlet is positioned in line with the inlet, coded C, so hoses can run parallel and reduce bends. Case drainage returns through a 1/2 NPT tank port to minimize backpressure. A 2-bolt flange mounting pattern anchors the housing to a power unit or motor adapter with minimal hardware. Torque reaches the shaft via an 11-tooth spline whose 0.590 in minor diameter fits common female hubs. The spline geometry uses a 16/32 DP pitch and a 30° pressure angle, ensuring smooth power transfer and consistent alignment during long-term service.
