V20-1S7R-1A-11

The V20-1S7R-1A-11 vane pump is manufactured by Vickers and belongs to the Vane Pumps series for hydraulic automation tasks that require consistent fluid delivery. Design number 11 identifies the current engineering version so service parts match precisely. Clockwise rotation ensures proper internal timing when the drive shaft turns in the specified direction. A single lip shaft seal holds system oil inside the housing while keeping external contaminants out of the drive end. Sealed bearings retain their own grease supply and block hydraulic fluid from washing through the rolling elements. The standard cover type supplies normal housing stiffness without optional performance inserts.

A flange, 2-bolt SAE A mounting pattern allows the pump to bolt directly to common industrial motor adapters and reduce alignment time. The inlet port is threaded 1.625-12 UN-2B, providing a large suction passage that minimizes inlet restriction at the pump’s rated speed. Pressure flow exits through a 1 in NPTF outlet port that mates with standard steel pipe fittings used in moderate-pressure circuits. The outlet is located opposite the inlet, which keeps suction and pressure hoses on opposing faces to simplify routing. At 1200 rpm and 100 psi the pump delivers 7 US gpm, supplying a predictable volume for medium-duty hydraulic actuators.
