The 45V42A 1A22R model belongs to the V Series Vane Pumps and is manufactured by Vickers for hydraulic automation that requires reliable oil flow. The unit displaces 138 cm³ per revolution, and at 1200 rpm with 100 psi it delivers 42 gpm to keep actuators supplied. Clockwise rotation matches common drive shafts, while a 5/16 in square key secures the coupling against torsional load. A flange-mount housing lets installers bolt the pump directly to power packs. Continuous service spans from a minimum of 600 rpm to a maximum of 1800 rpm, providing flexibility for variable-speed drives. Acoustic output is 67 dB(A) at 1200 rpm, supporting workplace noise targets.
The hydraulic interfaces use standard SAE patterns for straightforward plumbing. Fluid enters through an FL-24 four-bolt SAE inlet flange and exits through an FL-12 four-bolt SAE outlet flange. The outlet sits opposite the inlet so parallel hose routing is possible inside compact enclosures. The inlet side tolerates up to 1.4 bar (20 psi) to avoid cavitation at high flow, and the pressure side handles 172 bar (2500 psi) on AW-grade oil for medium-pressure circuits. These port sizes, positions, and pressure limits define how the 45V42A 1A22R integrates into automated hydraulic systems.
