The V20F 1P6P 38C8H 22 vane pump is manufactured by Vickers and belongs to the Square Vane Pumps series. It supplies hydraulic actuators with pressurized fluid for automation loops. The pump displacement is 19.5 cm³ per revolution, which defines the volume of oil delivered each shaft turn and governs flow rate selection. A No. 8 flow orifice rated at 8 US gpm sets the nominal throughput for fixed flow circuits. The inlet connection is a 1-1/4 in NPT port, allowing direct attachment to common suction lines, while permissible inlet conditions include up to 0.7 bar positive pressure or a vacuum of 5 in Hg, safeguarding against cavitation. Right-hand clockwise rotation matches standard electric motor drives, and the 2-bolt flange mounting simplifies rigid installation on power units. A SAE rated capacity of 6 US gpm at 1200 rpm and 100 psi indicates baseline performance for sizing the prime mover.
During operation the pump tolerates a maximum system pressure of 172 bar, enabling it to service medium-pressure tooling circuits. Shaft speed can reach 3400 rpm, giving headroom for variable-speed applications. Discharge fluid exits through a 3/4-16 UNF SAE O-ring boss outlet that is arranged in line with the inlet to simplify hose routing in compact reservoirs. An internal relief valve is preset to open at 140 bar to protect downstream components from overloads. Power transfer occurs through a 16/32 DP spline with 11 teeth and a 30° pressure angle, ensuring accurate torque transmission to the drive shaft. Return fluid can be routed to a 1/2 in NPT tank port for low-pressure drainage. Together these characteristics complete the hydraulic data required for integrating the V20F 1P6P 38C8H 22 unit in automated machinery.
