Description & Features

Designed for fixed-displacement external gear pumping across a wide range of mobile and industrial equipment, the Danfoss / Eaton ACNAR09AJA00400000000A0A is part of the Series 26 gear pump family. It is suited for use in tractors and harvesters, machine tools, steering circuits, compactors, sweepers, rotary and reel mowers, lift trucks, fan drive systems, and auxiliary work circuits.

The pump features field-reversible direction, allowing flexible installation and adaptation to different circuit configurations without replacing the unit. Reduced noise and vibration characteristics make it well-suited for operator-sensitive environments, while improved volumetric and mechanical efficiency support consistent performance across varying load conditions. A minimum working temperature rating of -20°C covers cold-climate applications. The unit is supplied under the Danfoss Power Solutions brand.

Question by: Clint P on Feb 16, 2026, 11:35 AM
Reckon this pump would hold up alright on a mower that runs pretty much all day during the summer?
Answer by: Customer Support on Feb 17, 2026, 5:57 PM
Improved volumetric and mechanical efficiency on this Series 26 gear pump helps it maintain consistent performance even when loads are up and down, which would be beneficial for a mower seeing continuous use.
Question by: Howard C on Dec 23, 2025, 8:14 AM
pump direction reversible on this one, or do I need to order a specific rotation when I buy it?
Answer by: Customer Support on Dec 25, 2025, 8:08 AM
Field reversible is built right into this pump, so you can flip the rotation direction without swapping out the unit. That gives you some real flexibility when fitting it into different circuit configurations or if your setup changes down the road.
