The 3525V30A21 1AC22R pump is part of the V Series Vane Pumps from Vickers and serves as a hydraulic power source for automated machinery. It weighs 34.5 kg (76 lb) and turns in a clockwise direction to match common industrial drive layouts. The assembly is rated for a maximum speed of 1800 rpm, allowing high-cycle operation in production lines. At the shaft end, displacement reaches 97 cm³ per revolution (5.9 in³/rev), which produces a delivery of 30 US gpm when the drive motor runs at 1200 rpm. The same port can withstand 172 bar (2500 psi) so downstream actuators receive consistent pressure. Fluid enters through a SAE 4-bolt flange on the inlet side, and the suction line may be pressurized up to 1.4 bar (20 psi) to reduce cavitation during cold starts.
The cover end handles 67 cm³ per revolution (4.1 in³/rev) and supplies 21 US gpm at 1200 rpm, giving designers a second flow source within the same housing. This section also supports a working pressure of 172 bar (2500 psi) so both circuits share identical load limits. Inlet vacuum is limited to 5 inHg, which defines the acceptable lift height for reservoir mounting. The primary outlet is located opposite the inlet and uses a matching SAE 4-bolt flange, simplifying manifold connections. A secondary outlet sits 45° clockwise from the inlet to accommodate offset plumbing runs without extra elbows. These port orientations allow simultaneous service to parallel actuators while keeping line routing compact.
