The V20NF 6S7T 15D5H 22R 151 pump belongs to the Square Vane Pumps series and is manufactured by Vickers for hydraulic automation where steady oil delivery is required. A flow-control cover with an internal drain regulates outlet flow and directs case leakage back to suction for efficiency. The displacement of 22.8 cm³ per revolution determines the theoretical volume moved each cycle, while a ring capacity of 7 US gpm defines the fixed flow that can be supplied at reference speed. A maximum operating pressure of 172 bar limits system loading to prevent component fatigue, and a maximum speed of 3000 rpm sets the highest permissible drive velocity. The SAE-B two-bolt flange mounting interface aligns the housing with standard power units, the 1.625-12 UN-2B inlet thread secures the suction hose, and a 0.750-16 UNF-2B primary outlet thread provides the main pressure connection.
A 0.875-14 UNF-2B secondary outlet thread offers a dedicated port for auxiliary circuits, while a 0.750-16 UNF-2B tank port thread returns excess fluid to the reservoir. The 1.69-inch shaft extension length positions the drive hub, and a 0.873-inch shaft major diameter establishes the fit with couplings. Torque transfer is handled by a 13-tooth 16/32 DP spline, and a single-lip shaft seal retains fluid inside the case while excluding airborne contaminants. Sealed bearings keep internal lubrication intact and extend service life by blocking external debris.
