The V20F 1P11P 38D6F 22L pump is produced by Vickers within the Vane Pumps series to deliver pressurized oil in hydraulic automation systems. Its displacement of 36.4 cm³/rev (2.22 in³/rev) defines the volume moved per shaft revolution, while a controlled flow setting of 6 USgpm lets designers establish a low fixed-delivery mode for steady-state circuits. A rated capacity of 42 L/min (11 USgpm) indicates the continuous flow obtainable at nominal speed and pressure. The maximum operating pressure reaches 172 bar (2500 psi), providing margin for cylinders and motors that demand moderate force, and a relief valve setting of 1500 psi limits overload by venting excess pressure to tank. The shaft minor diameter of 0.590 in fits common flexible couplings, and a 2-bolt flange mounting pattern secures the housing to power-unit brackets without additional adapter plates.
The pump accepts rotation in a left-hand (CCW) direction, so drive components must match this orientation. It withstands up to 2500 rpm maximum speed, allowing variable-frequency electric motors to exploit the full flow range. Fluid enters through a 1.25 in NPT inlet port and exits through a 0.750-16 UNF ORB outlet port, with the outlet positioned 90° clockwise from the inlet to simplify right-angle plumbing layouts. Return flow is routed to reservoir via a 0.50 in NPT tank port. Dimension A measures 161.0 mm (6.34 in) from the mounting face to the rear cover, and Dimension B measures 136.9 mm (5.39 in) from the shaft centerline to the base, giving designers clear envelope data for compact power packs.
