DANFOSS / EATON ACMAR079905AA0500160000A0A00000B

Description & Features

Designed for demanding mobile and industrial hydraulic applications, the Danfoss / Eaton ACMAR079905AA0500160000A0A00000B is a Series 26 fixed displacement external gear pump built to perform across a wide range of equipment types. Its construction targets reduced noise and vibration alongside improved volumetric and mechanical efficiency, characteristics that matter in continuous-duty circuits.

This pump supports field-reversible rotation, allowing direction to be changed without replacing the unit, a practical advantage during installation or equipment reconfiguration. Rated for a minimum working temperature of -20°C, it is suited for use in tractors, harvesters, compactors, sweepers, lift trucks, rotary and reel mowers, machine tool circuits, fan drive systems, and auxiliary work circuits. Steering circuit applications are also supported.

Question by: Ralph W on Mar 3, 2026, 1:00 PM
pump says it's field reversible, how hard is that to actually do in the field, or is it more of a one-time setup thing?
Answer by: Customer Support on Mar 5, 2026, 6:45 AM
Changing rotation direction on this unit doesn't require swapping it out for a different pump, which is the main advantage. It's meant to be done during installation or when reconfiguring equipment, so it's more of a setup step than something you'd be flipping back and forth on a regular basis. Handy when you're putting it on a machine that runs the opposite direction from what you originally planned for.

Will this gear pump hold up on my tractor, running most of the day?
Answer by: Customer Support on Feb 24, 2026, 6:45 AM
This Series 26 pump is built for continuous-duty circuits, so it should be suitable for extended use in tractors and harvesters. Just be sure to stay within the specified temperature range of -20°C.
