Cessna/Eaton Hydraulic Pumps, Motors & Replacement Parts

Cessna/Eaton Hydraulics traces to the Cessna hydraulics division established in the post-WWII period (around 1945, exact year unconfirmed), which built gear, piston, and vane pumps along with hydraulic motors, cylinders, and valves for mobile and industrial fluid power. The line passed into Eaton’s hydraulics business and is now part of Danfoss Power Solutions, following Danfoss’s 2021 acquisition of Eaton Hydraulics. Danfoss operates from Nordborg, Denmark, with US power-solutions operations in Ames, Iowa. Northern Hydraulics supplies and cross-references Cessna/Eaton hydraulic components, with roughly 214 pumps and related parts cataloged for replacement and equivalent applications.

Cessna/Eaton Hydraulics Product Lines & Series

The Cessna/Eaton catalog centers on its gear-pump families and piston-pump line, which carry the bulk of the aftermarket demand:

• Series 24 gear pumps — including units such as the 24300-LZA and 24304-LZB models, part of the Cessna/Eaton gear pumps range.
• Series 25 gear pumps — a parallel gear-pump family for mobile and industrial duty.
• Series 26 gear pumps — the larger-displacement gear-pump family in the lineup.
• 7000 series variable piston pumps — the variable-displacement piston-pump line, listed alongside the full Cessna/Eaton hydraulic pumps catalog.
• Vane pumps, hydraulic motors, cylinders, and valves — rounding out the range, including single-line hydraulic vane pumps.

Cross-Referencing Cessna/Eaton Hydraulics Parts

Because the brand has moved from Cessna to Eaton and now to Danfoss, the same pump can carry different part numbers across catalogs, and older units are increasingly hard to source by their original designation. We cross-reference Cessna/Eaton pumps to current replacement and equivalent parts — drop-in equivalents exist for many gear and piston models, including Series 24 units like the 24300-LZA and 24304-LZB. If you have a legacy or discontinued Cessna/Eaton pump and need a match on displacement, rotation, and port configuration, send us the casting number, model number, or nameplate data and we will identify the equivalent.
