VICKERS-4520V50A11 1AC22R

Description & Features

Built for demanding industrial hydraulic circuits, the Vickers 4520V50A11 1AC22R is a double vane pump from the Vickers V Series, manufactured under the Vickers brand by Danfoss/Eaton. Constructed with a cast iron housing and Buna-N seals, it is suited for continuous-duty applications across a broad range of industries, including plastics machinery, die casting, press machines, machine tools, oil and gas, marine, pulp and paper, wood processing, primary metals, and general industrial use.

The 4520V Series utilizes an innovative intra-vane cartridge design that reduces operating noise while maintaining excellent volumetric efficiency, two characteristics that matter in production environments where consistent output and low acoustic signature are priorities. With no special features listed, this is a standard-configuration unit ready for direct integration into compatible hydraulic circuits.

Running a press machine setup and need something that ain't gonna sound like a helicopter in the shop. Does the intra-vane design on this actually make a noticeable difference in noise, or is that just marketing talk?

Answer by: Customer Support on Jan 26, 2026, 7:03 PM

Cast iron housing combined with the intra-vane cartridge design genuinely does cut down on operating noise compared to conventional vane pump configurations. The intra-vane approach keeps the vanes loaded more consistently against the cam ring, which smooths out pressure pulses and reduces the acoustic signature during operation. For a press machine environment where the pump runs most of the day, that's a real-world difference you'll notice on the floor, not just on paper.
