V10 1P4P 12A20

The V10 1P4P 12A20 vane pump is produced by Vickers within the Square Vane Pumps series and provides controlled fluid flow for hydraulic automation circuits. Design code 20 identifies the internal cartridge version so replacement parts match dimensional tolerance requirements. The displacement of 13.1 cm³ per revolution defines how much oil is transferred each shaft turn, giving predictable flow rates across the speed range. At 1200 r/min and 100 psi the pump delivers 15 L/min, letting system designers choose correct line sizes and cooling capacity. A maximum operating pressure of 172 bar allows the unit to support medium-pressure actuators without overstressing the housing. Fluid enters through a 1 in NPT suction port, a common connection that simplifies pipework. A two-bolt flange mounting secures the pump to motor adapters and keeps shaft alignment stable under load.

An inlet vacuum limit of 5 inHg restricts suction line pressure drop to prevent cavitation and maintain vane lubrication. The permitted supercharge inlet pressure of 0.7 bar (10 psi) enables the use of boost pumps that improve filling yet stay below seal load limits. A maximum speed of 3400 r/min supports higher flow demands while keeping bearing velocities within safe margins. The outlet port sits opposite the inlet, identified as Code A, so discharge lines can be routed in a straight run for compact installation. Internal ring size 4 sets the cam eccentricity that produces the stated displacement, and this dimension keeps radial forces balanced during full pressure operation.
