The 4525V60A21 1CC22R pump is part of the V Series Vane Pumps from Vickers and is intended for hydraulic automation where dependable dual-section flow is required. A flange mount secures the unit rigidly to the power pack, and clockwise rotation viewed from the shaft end matches common electric-motor drives. Torque is transmitted by a 5/16 in square shaft key. The cover end delivers 67 cm³ per revolution (4.13 in³/rev), producing a rated flow of 21 gpm, while the shaft end supplies 193 cm³ per revolution (11.75 in³/rev) to reach 60 gpm. Both ends operate continuously at 172 bar (2500 psi), so a single housing can support high-pressure work circuits without derating.
The inlet side permits up to 1.4 bar (20 psi) pressure and tolerates vacuum down to –0.17 bar (5 inHg), allowing installation above the reservoir if needed. Outlet 1 is inline with the inlet to simplify straight piping runs, whereas outlet 2 is positioned 45° clockwise from the inlet for compact return layouts. All ports use SAE four-bolt flanges, and the threads are inch pattern, enabling direct connection to standard American fittings without adapters.
