Description & Features

Designed for demanding industrial and mobile applications, the Danfoss / Eaton Pump is a fixed displacement external gear pump built to perform across a broad range of sectors including agriculture, civil engineering, material handling, metal forming, and specialty construction.

Engineered with reduced noise and vibration in mind, this Series L2 unit delivers improved volumetric and mechanical efficiency suited to continuous-duty hydraulic circuits. A field-reversible pump direction adds flexibility during installation and system reconfiguration, minimizing downtime in the field. The pump is rated for operation down to -20°C minimum working temperature, making it suitable for use in colder environments and seasonal outdoor equipment.

Supplied under the Eaton Char-Lynn brand, now part of Danfoss Power Solutions.

Question by: Johnny A on Jun 9, 2025, 8:59 AM
got a machine that needs a quiet gear pump, is this one built to cut down on the racket?
Answer by: Customer Support on Jun 10, 2025, 7:19 PM
Reduced noise and vibration is one of the listed features on this Series L2 external gear pump, along with improved volumetric and mechanical efficiency.
Question by: Todd B on Feb 28, 2026, 7:30 PM
pump says it's field reversible -- how hard is that to actually do out in the field, or is it more of a shop job?
Answer by: Customer Support on Mar 2, 2026, 6:36 AM
Reversing the rotation on this pump is genuinely meant to be done without sending it back to a shop. The Series L2 is built so the direction can be swapped in the field, which makes it practical for equipment that gets reconfigured or when a replacement ends up being plumbed opposite from the original. You won't need special tooling or a rebuild to make that change.
