The 3520V25A14-1BA20 vane pump is manufactured by Vickers for the Vane Pumps series and supplies hydraulic power to automated machinery. The shaft end provides a displacement of 81.6 cm³ per revolution, which lets the pump deliver 25 US gpm at 1200 rpm to main working circuits. That end is built for pressures up to 210 bar, so it can support high-load actuators without overstressing the housing. A total mass of 34.0 kg places the unit in stationary power packs rather than portable service tools, and its dual-stage design means both flow paths share one drive shaft for compact installation.
The cover end of the same pump supplies 45.9 cm³ per revolution to auxiliary lines, generating 14 US gpm at 1200 rpm for pilot or cooling functions. Its pressure capability is limited to 140 bar, allowing engineers to separate low-force tasks from the higher-pressure shaft end. Inlet conditions must stay below 1.4 bar and above a vacuum of 5 in Hg to avoid cavitation and maintain smooth priming. These operating limits combine with the dual outputs to make the 3520V25A14-1BA20 a compact solution when a single motor must feed circuits that run at different pressures.
