3520VQS30AM5

The 3520VQS30AM5 is manufactured by Vickers for the Vane Pumps series and supplies pressurised fluid to hydraulic automation circuits. The front pumping section displaces 97.7 cm³ per revolution, setting the primary flow capacity for work ports, while the rear section delivers 18.0 cm³ per revolution to provide an auxiliary stream for secondary functions. Both sections can run at speeds up to 2500 r/min, letting drive motors cycle equipment rapidly without inducing flow starvation. A working limit of 210 bar across both sections equips the unit to power cylinders and motors that need medium-to-high system pressure.

The inlet side tolerates a vacuum no greater than 5 inHg, a restriction that prevents vapour cavitation during high suction demand, and it accepts up to 1.4 bar positive pressure so flooded suction lines can be used where available. Connection to the hydraulic circuit is made with metric four-bolt flanges that create rigid, leak-free joints under fluctuating load. The housing aligns to prime movers through an SAE J744 (ISO 3019-1) mounting pilot, enabling direct installation on standard industrial frames. These interface limits and mounting standards support reliable operation when consistent flow and pressure from both pumping stages are needed in automated machinery.
