Description & Features

Designed for high-pressure, high-speed hydraulic service, the Vickers 4520VQH50A8 86AA20 is a heavy-duty vane pump from the 4520VQ series, manufactured by Vickers by Danfoss/Eaton. Built from cast iron with Buna-N seals, it delivers a flow rate of 308.98 litres per minute and is suited to demanding continuous-duty applications across a broad range of industries.

Typical applications include plastics machinery, press machines, die casting, machine tools, test equipment, primary metal processing, pulp and paper, wood processing, oil and gas, marine, and general industrial use. The VQ(H) series is noted for its volumetric efficiency and extended service life, making it a practical choice where reliable output and durability under sustained load are priorities.

Question by: Rusty R on Oct 5, 2025, 6:38 AM
How long can I expect this Vickers pump to last if I'm running it pretty much non-stop?
Answer by: Customer Support on Oct 6, 2025, 1:51 PM
The VQ(H) series is known for its extended service life, so it should hold up well even under demanding, continuous-duty applications.
Question by: Freddie B on Sep 14, 2025, 7:42 AM
Running a press machine that stays pretty much wide open all shift, five days a week. This pump gonna hold up to that kind of continuous load, or is it more of a light-duty piece?
Answer by: Customer Support on Sep 16, 2025, 7:08 AM
Continuous heavy-duty service is exactly what the VQ(H) series was built for. The cast iron housing handles sustained mechanical stress better than aluminum-bodied alternatives, and the Buna-N seals are rated for the kind of heat cycles you see in press applications. Volumetric efficiency stays strong over time, which matters when you're trying to hold consistent output across a full shift without pressure drop-off creeping in on you.
