The 4525V60A21 1DC22R pump belongs to the V Series Vane Pumps manufactured by Vickers and supplies hydraulic flow for automation systems. It is a vane pump configured as a double pump, so two pumping sections share a common drive to serve separate circuits. The cover end delivers 67 cm³ per revolution while the shaft end moves 193 cm³ per revolution, establishing different flow volumes from each section. At 600 rpm minimum speed both sections remain lubricated and able to prime fluid. The first hydraulic section is rated at 60 gpm, and the second section is rated at 21 gpm, providing distinct flow capacities for paired actuators. Clockwise rotation matches standard right-hand drive arrangements, and flange mounting allows direct attachment to SAE engine housings.
Each pumping section withstands 172 bar (2500 psi) maximum pressure, supporting medium-pressure circuits without external relief. The outlet can be oriented at 90° clockwise or 45° clockwise from the inlet, letting installers align hoses within confined frames. Fluid leaves through SAE four-bolt flanges that present a rigid seal against high line loads, and inch threads on the ports simplify coupling to North American pipe fittings. Because the ports are on flanges rather than pipe taps, induced stress on the housing stays low. These connection features complement the compact double-pump layout to streamline manifold design and maintain reliable operation in automated hydraulics.
