Description & Features

Designed for power steering systems and industrial applications including small press units, the Vickers 2520VQ21A14 11AA20 is a double vane pump from the 2520VQ series, built to handle high-pressure, high-speed service. Cast iron construction provides durability under demanding conditions, while Buna-N seals offer reliable fluid compatibility across common hydraulic media.

With a flow rate of approximately 148.7 litres per minute, this pump delivers the output capacity suited to compact industrial circuits requiring consistent volumetric efficiency. The vane pump design supports longer service life compared to many gear-type alternatives, with low internal leakage contributing to sustained performance over extended duty cycles.
