Description & Features

Designed for demanding industrial applications, the Vickers 2520V21A8 1AA22R is a cast iron vane pump from Eaton Vickers' V Series, built for reliable hydraulic performance across metal cutting, plastic injection molding, oil and gas, dump truck, and wheel loader applications.

The pump features an innovative intra-vane cartridge design that reduces operating noise while maintaining excellent volumetric efficiency. With a flow rate of approximately 121 liters per minute and Buna-N seals, it is well suited for systems requiring consistent fluid delivery under variable load conditions. The cast iron housing provides durability in heavy-duty industrial environments.

Part of the Vickers VHO series, this pump is a direct replacement option where Eaton Vickers vane pumps are specified. The alternate part number 2520V21A81AA22R may be used for cross-reference purposes.

Question by: Jerry P on Feb 19, 2026, 10:00 AM
Will this Vickers pump bolt right in where the old one was on my dump truck?
Answer by: Customer Support on Feb 20, 2026, 6:27 PM
This V series vane pump is often used as a direct replacement option when that Eaton Vickers model is already spec'd. To be sure, double check the dimensions and mounting configuration against your existing pump.
Question by: Rex P on Nov 29, 2025, 8:05 PM
flow rate on this pump is listed around 121 liters per minute -- that accurate for what it'll push in a metal cutting setup?
Answer by: Customer Support on Dec 1, 2025, 7:15 AM
Yeah, 121.23 liters per minute is the rated flow for this unit. For metal cutting applications, that's a solid output and the pump is specifically listed for that use. The intra-vane cartridge design helps keep volumetric efficiency consistent, so you're not seeing a lot of internal slip eating into that number under normal load conditions.
