The 25VTBS17A 2203AA 22R pump is produced by Vickers within the V Series Vane Pumps and serves as a fixed-displacement source of hydraulic flow for automated machinery. Its geometric displacement is 55 cm³ per revolution, setting a constant volume transfer per shaft turn. When operated at 1200 rpm and 100 psi, the unit delivers a rated capacity of 17 gpm, providing a baseline for circuit sizing. A minimum speed of 600 rpm is required to maintain internal lubrication, while a maximum speed of 1800 rpm limits peripheral velocity at the vanes. Right-hand (clockwise) rotation matches common electric motor outputs, and a maximum continuous pressure of 172 bar defines the highest working pressure the casing and rotor can withstand. The outlet is positioned opposite the inlet in the A orientation, which helps streamline hose routing on single-pump installations.
A maximum input shaft torque of 400 Nm specifies the largest driving moment the shaft can accept without fatigue, and a thru-drive torque rating of 316 Nm governs the load that may be transferred to an auxiliary pump connected in tandem. The included thru-drive coupling allows direct mechanical linkage to that secondary unit. SAE 4-bolt flange port connections standardize hose attachment points, while the ISO 3019/1 (SAE J744) pilot interface aligns the housing accurately on the mounting pad. Rear pump mounting follows the SAE B 2-bolt pattern so the pump can be fastened to a power take-off or adapter with minimal hardware. Inlet conditions are bounded by a maximum of 1.4 bar to protect seals and a minimum of –0.17 bar to ensure adequate suction without cavitation.
