Designed for power steering systems and industrial applications such as small press units, the Vickers 2520VQ21A12 11AA20 is a double vane pump built to handle high-pressure, high-speed duty cycles. Part of the Eaton Vickers 2520VQ series, it delivers a flow rate of approximately 148.7 litres per minute, making it well suited to demanding hydraulic circuits where consistent volumetric output is critical.
Cast iron construction provides durability in continuous-duty industrial environments, while Buna-N seals offer reliable fluid compatibility across common hydraulic media. The pump is engineered for extended service life and maintains strong volumetric efficiency throughout its operating range, characteristics that reduce downtime and support stable system performance in both mobile and stationary hydraulic equipment.

Product Questions & Answers (3)
Question by: Brent S on Sep 29, 2025, 6:25 AM
got a small press unit that runs pretty hard, is this 2520VQ pump meant for high pressure and higher rpm work?
Answer by: Customer Support on Oct 1, 2025, 6:50 AM
Built for high pressure and high speed duty cycles, the 2520VQ series double vane design is a common fit for small press units and other compact industrial hydraulic setups where steady flow matters.
Question by: Terry M on Jul 31, 2025, 11:51 AM
Flow rate on this one's listed close to 149 liters a minute, that right for the 2520VQ21A12 11AA20, or is that a peak number?
Answer by: Customer Support on Aug 1, 2025, 1:36 PM
That 148.7 liters per minute figure is the rated flow output for this pump. It's not a burst or peak rating listed as a caveat, it's the stated delivery rate for this model in the 2520VQ series. If your circuit sizing is based on that number, you're working from the right spec.
