The V20 1P9P 15B11 pump belongs to the Square Vane Pumps series and is manufactured by Vickers for hydraulic automation where consistent fluid delivery is required. A displacement of 29.7 cm³ per revolution sets the volume of oil moved with each shaft turn, establishing predictable flow calculations. Its flow rate of 76.27968 l/min supplies sufficient oil for medium-capacity circuits. The minimum operating speed of 1800 rpm prevents cavitation at the inlet and maintains lubrication of internal vanes. Right-hand shaft rotation must be observed so the vanes seat correctly during operation. A 2-bolt SAE A flange provides standard mounting for quick replacement or new installations. The 1-1/4 in NPT threaded inlet port accepts common suction line fittings, simplifying plumbing. A maximum working pressure of 172 bar defines the upper system limit and protects downstream components from overload.
The outlet port sits 90° counter-clockwise from the inlet, a layout that aids compact hose routing in confined frames. Internal ring size 9 matches the displacement group and maintains sealing clearances under load. Cast-iron construction resists wear and absorbs vibration in continuous duty cycles. A weight of 18 lb allows one person to position the unit without lifting equipment. Overall length is 7.84 in, width is 5.12 in, and height is 4.79 in, dimensions that determine the space envelope for pump installation inside hydraulic power units.
