The 25V17A 11B22R vane pump belongs to the V Series Vane Pumps and is produced by Vickers for fixed-displacement hydraulic automation. It delivers 55 cm³ per revolution, which corresponds to 17 gpm at 1200 rpm and 100 psi, providing steady flow for cylinders and motors. The housing withstands a continuous working pressure of 172 bar while the inlet side tolerates up to 1.4 bar to curb cavitation. A drive rating of 250 N·m defines the maximum torque the shaft can accept. Operating speed is limited to 600 rpm at the low end for oil film integrity and 1800 rpm at the high end when anti-wear oil is used. The shaft rotates clockwise, aligning with common right-hand electric motor outputs.
This pump installs with a flange mount, using an FL-12 inlet flange for suction and an FL-8 outlet flange for discharge. Both connections follow the SAE four-bolt pattern, and a standard SAE pilot centers the body during assembly. The outlet port is positioned 90° counter-clockwise from the inlet, allowing simple hose routing inside compact power units. Power transfer relies on a 13-tooth 16/32 spline, and the major diameter of that spline is 22.17 mm, so mating couplings must match this profile to maintain drive integrity.
