Description & Features

A double-unit vane pump built for demanding industrial and mobile hydraulic circuits, the Vickers 2520VQ21A12 11CC20 belongs to Eaton Vickers' 2520VQ series and is designed for high-pressure, high-speed service. Cast iron construction contributes to durability under sustained load, while Buna-N seals provide reliable fluid compatibility across typical hydraulic media.

With a flow rate of approximately 148.7 litres per minute, this dual-section pump suits applications including power steering systems, small industrial press units, and compact hydraulic power units. The series is engineered for outstanding volumetric efficiency and extended service life, making it a practical choice where consistent output and long intervals between maintenance are priorities.

Built for high-pressure, high-speed applications, the Vickers 2520VQ vane pump is designed to offer longer operating life, even under demanding duty cycles in industrial settings.
Question by: Cody S on May 22, 2025, 6:25 PM
got a small press that runs a vane pump now. is this 2520VQ one meant for that kind of setup?
Answer by: Customer Support on May 24, 2025, 6:22 AM
Common uses for the 2520VQ series include industrial small units and small presses, so it lines up well with that type of application.

Got a worn-out vane pump on a small hydraulic press and tryin to figure out if this 2520VQ21A12 would be a drop-in situation. What's it built out of and what kinda seals does it run?
Answer by: Customer Support on Jun 7, 2025, 8:36 PM
Cast iron housing with Buna-N seals throughout. For a small press application that's a pretty common and solid setup. The 2520VQ series from Eaton Vickers is built to handle high-pressure, high-speed conditions, so a small press environment is right in its wheelhouse. Just make sure your existing system matches the flow requirements since this unit puts out just under 149 liters per minute.
