DANFOSS / EATON ACNAR04ACA0040000000000A

Description & Features

Designed for demanding mobile and industrial hydraulic applications, the Danfoss / Eaton ACNAR04ACA0040000000000A is a fixed displacement external gear pump from the Series 26 family. It operates reliably in a minimum working temperature of -20°C, making it well suited for equipment exposed to cold-climate conditions.

This pump is engineered for reduced noise and vibration, with improved volumetric and mechanical efficiency compared to conventional gear pump designs. The field-reversible pump direction adds installation flexibility across a broad range of circuit configurations. Typical applications include tractor and harvester hydraulics, machine tool circuits, steering systems, compactors, sweepers, rotary and reel mowers, lift trucks, fan drive systems, and auxiliary work circuits.

Got a sweeper running on a pretty basic hydraulic circuit, this Series 26 pump work alright for that kind of application?

Answer by: Customer Support on Mar 17, 2026, 6:08 AM

Sweepers are actually listed right in the application range for this pump, so you're in good shape there. The Series 26 is built for exactly that kind of mobile equipment work, and it carries improved volumetric and mechanical efficiency over standard gear pump designs, which helps keep things running smooth on circuits that don't need a lot of complexity.
