Description & Features

Designed for power steering systems, industrial small units, and small press applications, the Vickers 2520VQ21A11 11BC20 is a double vane pump from the Vickers by Danfoss/Eaton VQ Series. Built from cast iron, it delivers a flow rate of approximately 148.7 litres per minute and is rated for high-pressure, high-speed service.

The VQ Series design is well regarded for strong volumetric efficiency and extended service life under demanding cycle conditions. The cast iron construction supports durability in continuous industrial use, while the series configuration allows for combined flow output suited to multi-circuit hydraulic systems.

Question by: Neal P on Dec 27, 2025, 11:39 AM
Running a small press setup and need decent flow without going oversized on the pump. Does the 2520VQ series put out enough to handle that kind of work, or am I gonna be shorting myself on volume?

At roughly 148.7 litres per minute, this double vane pump puts out a solid flow rate for small press applications. The 2520VQ series was built with exactly that use case in mind, alongside industrial small units and power steering systems. The double vane configuration also means you're getting combined flow output suited to multi-circuit setups, so if your system runs more than one circuit, you've got room to work with there too.

Reckon this'll hold up okay in a shop that runs equipment pretty much all day long?
