V10 1S7S 1C20

The V10 1S7S 1C20 vane pump belongs to the Square Vane Pumps series and is manufactured by Vickers for hydraulic automation circuits that need a fixed displacement source of flow. Its displacement is 22.8 cm³ per revolution, so each shaft turn moves a precise fluid volume for predictable actuator speed. At 1200 rpm and 100 psi the pump produces a rated delivery of 7 US gpm, giving designers a reference point for system sizing. It tolerates a maximum operating pressure of 138 bar, allowing it to drive cylinders and motors in medium-pressure machines. A permitted top speed of 2800 rpm lets the pump mate directly to common electric or diesel prime movers without overspeeding. Right-hand rotation when viewed from the shaft end matches clockwise engine outputs, simplifying drive selection. The shaft major diameter of 0.750 in fits standard couplings, and a 0.187 in square key secures torque transmission between shaft and driver.

The pump mounts with a two-bolt flange, holding the housing rigidly to a pad or bracket and preserving alignment under load. An inlet port threaded 1.3125-12 UN-2B accepts SAE-style fittings for reliable suction connections, while the outlet port threaded 3/4-16 UN-2B supports pressure line hardware of matching size. Both ports sit in line, which streamlines hose routing and reduces space requirements in compact power units. Inlet pressure on the positive side must not exceed 0.7 bar; staying below this limit prevents seal damage and reduces shaft loading. The design also allows up to 5 inHg of inlet vacuum so the pump can draw fluid from reservoirs placed slightly below it. These fluid handling limits, together with the mounting and port details, define the installation envelope and operating range for the V10 1S7S 1C20 in automated hydraulic equipment.
