Question by: Ronnie R on Feb 22, 2026, 4:29 PM
Been running a Series L2 gear pump on my ag equipment and need to swap it out. This the right replacement if I'm looking at the Danfoss Eaton lineup?
Answer by: Customer Support on Feb 24, 2026, 8:39 AM
For the Eaton Char-Lynn / Danfoss Power Solutions Series L2 lineup, yes, the 25500-LSA fits right in. It's a fixed displacement external gear pump with a 1.3 cubic inch per revolution displacement, so as long as that matches what you're pulling out, you're in good shape for agricultural applications specifically.

got an old Cessna gear pump on a farm rig, is this 1.3CIR one of those external gear pumps?
Answer by: Customer Support on Sep 12, 2025, 5:52 PM
Function-wise, it’s a hydraulic fixed displacement external gear pump in the Danfoss and Eaton Series L2 family, so it matches that style of pump used on a lot of equipment.
