The V10NF 1S5T S38C4H20L is produced by Vickers as part of the Square Vane Pumps series and is applied to provide steady fluid power in hydraulic automation systems. Its displacement is 16.4 cm³ per revolution, so each shaft turn transfers that volume of oil into the circuit. At 1200 rpm and 100 psi the unit delivers a rated capacity of 5 US gpm, establishing a reference point for sizing reservoirs and actuators. A No. 4 flow-control orifice restricts throughput to 15 L/min, enabling predictable flow when the unit is used with fixed-orifice networks. The maximum operating pressure reaches 172 bar, while an internal relief valve is preset at 140 bar to divert excess pressure before components are overstressed. These limits help maintain safe working conditions and reduce the need for external protection devices.
The pump can be driven up to 3200 rpm, allowing higher flow rates when the application demands faster cycling. It mounts on a two-bolt flange, so machine frames with this pattern can accept the housing without adapters. The inlet uses a 1-5/16-12 UN straight thread, and the outlet is aligned in-line with the inlet, simplifying rigid pipe runs in compact manifolds. Left-hand counter-clockwise rotation matches power units where prime movers turn in that direction. A spline with 11 teeth at a 16/32 DP profile couples the shaft to the driver, the minor diameter is 0.590 in, and the pressure angle is 30°, furnishing adequate torque transfer while minimizing wear on mating hubs. These mechanical features aid straightforward integration into standardized hydraulic power packs.
