Sauer-Danfoss (Danfoss Power Solutions) Pumps, Motors & Cross-Reference

Sauer-Danfoss formed as a 1986 joint venture rooted in Sauer Getriebe AG (founded 1967) and grew into one of the largest mobile-hydraulics lines in the industry: hydrostatic transmissions, closed-circuit and open-circuit axial piston pumps, bent-axis and orbital motors, directional and proportional control valves, steering units, and electronic control systems for agriculture, construction, material handling, and specialty vehicles. Danfoss A/S acquired the company in 2013, and the range now operates as Danfoss Power Solutions, headquartered in Ames, Iowa. The legacy Sauer-Sundstrand series remain in service across the field. Northern Hydraulics supplies and cross-references Sauer-Danfoss (Danfoss Power Solutions) components and provides compatibility support for the older Sauer-Sundstrand families.

Cross-Referencing Sauer-Danfoss (now Danfoss Power Solutions) Parts

Most buyers searching for a Sauer-Danfoss pump or motor are matching against an existing unit on a machine, and many of those part numbers are discontinued or have rolled into the Danfoss Power Solutions catalog. Give us the displacement, frame size, and the casting or nameplate number off the failed unit, and we cross-reference it to a current equivalent. Danfoss maintains a structured replacement program that sorts discontinued items into direct replacement, functional (non-form-fit) replacement, and obsolete-with-no-replacement categories, and we work from that documentation alongside the historical Sundstrand-to-Danfoss compatibility records for Series 15, 18, 20-27, 30, 40, 44/M46, 45, 51, and 90. If your part is fully obsolete, we identify the closest functional equivalent or interchange path rather than leaving you without an option. Send your Sauer-Danfoss or Sauer-Sundstrand part number and machine details to request a cross-reference quote.

Sauer-Danfoss (now Danfoss Power Solutions) Product Lines & Series

Sauer-Danfoss organized its catalog into well-defined series families, most of which carry forward under Danfoss Power Solutions:

• Series 90 closed-circuit axial piston pumps and motors, R and L frame variants, 30-250cc displacements
• Series 51 variable displacement bent-axis motors (V-series), 80-250cc
• Series 45 open-circuit pumps (E-frame)
• Series 40, 30, 20-27, 18, and 15 hydraulic and inline motors from the Sundstrand legacy line
• Orbital motors across the OMS, OMT, OMV, OMP, OML, OMM, TMK, TMT, and DH ranges
• PVG proportional valves, MVB modular valve blocks, and mobile directional and proportional control valves

If you only have a series designation and a displacement, that is usually enough for us to narrow the interchange. Send the numbers and we confirm the equivalent.
