Description & Features

Designed for demanding industrial applications, the Vickers 3520V25A5 11AA22R is a double vane pump from the Vickers VHO Series, built for consistent hydraulic performance in metal cutting, plastic injection molding, dump truck, wheel loader, and oil and gas equipment. Its cast iron housing provides durability under sustained duty cycles, while Buna-N seals deliver reliable fluid compatibility in standard hydraulic oil systems.

The pump features an innovative intra-vane cartridge design that reduces operating noise and maintains excellent volumetric efficiency across its flow range. With a rated flow of approximately 121.2 litres per minute, this unit suits high-demand circuits where consistent output and low noise are priorities. The Vickers brand, now part of the Danfoss/Eaton portfolio, carries a well-established reputation in industrial hydraulic systems for quality and parts availability.

Buna-N seals provide reliable fluid compatibility in standard hydraulic oil systems for this Vickers vane pump.
Question by: Dustin P on Apr 7, 2025, 6:36 PM
What kind of applications is this pump actually built for? Got a wheel loader sitting idle and trying to figure out if this unit would hold up on it.
Answer by: Customer Support on Apr 9, 2025, 2:42 PM
Wheel loader duty is one of the listed applications for this pump, along with metal cutting machines, dump trucks, plastic injection molding equipment, and oil and gas setups. The cast iron housing handles sustained duty cycles well, and the rated flow comes in at around 121.2 litres per minute, so it's got the output for demanding circuits. If your loader's hydraulic system is sized around that flow range, this unit is a solid fit.
