3525VQ35A17 1AA20

The 3525VQ35A17 1AA20 is a vane pump in the VQ Thru-Drive Vane Pumps series manufactured by Vickers for hydraulic automation systems. It transfers fluid power using right-hand (clockwise) rotation, which matches common prime mover direction in mobile and industrial equipment. At the shaft end the pump supplies a rated flow of 35 GPM, while the cover end offers 17 GPM to feed secondary circuits. These flow values are established on a capacity rating basis of 1200 rpm at 100 psi, giving designers a reference point when predicting performance under varying speed and pressure conditions.

The unit is produced to design code 20, identifying the internal component set and ensuring parts compatibility during service. Its outlet position is coded AA, meaning port O1 is opposite the inlet and port O2 sits 135° counter-clockwise, a layout that simplifies hose routing inside compact power packs. Fluid interface relies on SAE 4-bolt flange port connections, providing a rigid seal against leakage and allowing quick removal during maintenance. These configuration details help technicians integrate the pump into thru-drive arrangements where precise port orientation, standard flanges, and consistent component coding are essential.
