Description & Features

Designed for power steering systems, small industrial units, and light press applications, the Vickers 2520VQ21A11 11CC20 is a double vane pump from the Vickers by Danfoss/Eaton 2520VQ series. Cast iron construction contributes to durability in demanding service conditions, while Buna-N seals provide reliable fluid compatibility across standard hydraulic media.

This pump delivers a flow rate of approximately 148.7 litres per minute and is built to handle high-pressure, high-speed service. The vane pump design supports outstanding volumetric efficiency and extended service life, making it a practical choice for medium-duty industrial hydraulic circuits where consistent output and longevity are priorities.

Question by: Lance P on Jan 30, 2026, 1:03 PM
Flow rate on this one's listed close to 149 liters a minute, is that accurate for a double vane pump this size, or is that more of a peak figure?
Answer by: Customer Support on Feb 1, 2026, 7:34 AM
For a double vane pump in the 2520VQ series, that 148.69 litre per minute figure is the rated flow output. These pumps are built for high-speed, high-pressure service, and the vane design is specifically what makes that kind of consistent volumetric output achievable. Outstanding volumetric efficiency is one of the core features of this series, so that number reflects real working performance, not just a ceiling rating.
