The V20P-1P13T-3C4F-12 vane pump belongs to the Square Vane Pumps series and is manufactured by Vickers. It supplies hydraulic oil to automation circuits where moderate flow and compact mounting are required. The pump displaces 42.5 cm³ of fluid per revolution, which defines the volume moved each shaft turn. At its maximum speed of 2400 rpm it delivers 98.1 L/min (25.9 US gpm), giving systems high flow when peak demand occurs. When operated at 1200 rpm under a 100 psi load it provides 49 L/min (13 US gpm), supplying steady service flow for continuous duty machines. The unit withstands a system pressure up to 152 bar (2200 psi) so it fits medium-pressure loops. Right-hand rotation matches common clockwise prime movers, and a 2-bolt flange simplifies direct engine or motor attachment during installation.
Fluid enters through a 1.25 in NPT inlet, travels through the pumping chambers, and exits the primary outlet threaded .750-16 UNF-2B, with the outlet line positioned in line with the inlet to streamline pipe routing in tight manifolds. A dedicated priority orifice passes 15 L/min (No. 4) to auxiliary circuits, while an internal relief is preset to open at 100 bar (1500 psi) to protect downstream components from over-pressure. The pump uses Buna-N seals to resist common petroleum-based fluids and limit leakage. Return flow is routed to the tank through a .750-16 UNF-2B connection that matches the outlet thread for simplified hose selection. The housing weighs 18 lb, light enough for one-person handling during service.
