Description & Features

Designed for power steering systems, small industrial units, and light press applications, the Vickers 2520VQ21A5 11AA20 is a double vane pump from the Vickers by Danfoss/Eaton VQ series. Cast iron construction provides durability under continuous duty, while Buna-N seals deliver reliable fluid compatibility across common hydraulic fluids. The pump delivers a flow rate of approximately 148.7 litres per minute, making it well-suited to medium-demand hydraulic circuits.

Built to handle high-pressure, high-speed conditions, the 2520VQ series is recognized for outstanding volumetric efficiency and extended service life. The dual-section configuration allows combined or independent flow outputs from a single drive, a practical advantage in compact machine designs where minimizing drive components matters.

Will this pump work alright for power steering in a smaller industrial setup?
Answer by: Customer Support on Mar 14, 2026, 6:23 AM
It's designed for power steering systems, small industrial units, and light press applications. The flow rate should be suitable for medium-demand hydraulic circuits, too.
