Description & Features

Built for high-pressure, high-speed hydraulic circuits, the Vickers 3520VQ30E11 11AA20 is a double vane pump from the Vickers by Danfoss/Eaton VQ Series, designed to deliver reliable volumetric efficiency across demanding industrial environments. The cast iron housing provides durability suited to continuous-duty use, while Buna-N seals support compatibility with standard hydraulic fluids.

With a flow rate of approximately 215 litres per minute, this pump is well matched to high-flow applications including press machinery, die casting equipment, machine tools, plastics machinery, and test equipment. It also sees regular use in primary metals processing, pulp and paper, wood processing, oil and gas, and marine hydraulic systems.

The 3520VQ Series is recognized for extended service life and consistent performance in applications where both pressure and speed place sustained demands on pump components.

Question by: Randy J on Apr 14, 2025, 7:17 PM
We run press machinery pretty much around the clock. This a pump that can hold up to that kind of continuous load, or is it more of a light-duty unit?

Built around a cast iron housing and rated for high-pressure, high-speed circuits, the 3520VQ30E11 is well suited to continuous-duty industrial environments. Press machinery is actually one of the named applications for this series, so it's not a stretch to put it in that kind of demanding cycle. The VQ Series carries a reputation for extended service life, which matters a lot when your equipment doesn't get much downtime.

Reckon this pump will hold up running near constant in a plastics plant?

Cast iron construction makes this Vickers pump suitable for continuous duty in demanding industrial settings, so it should be a good fit for plastics machinery applications.
