Sauer Danfoss — Engineering Solutions & Services

Sauer Danfoss (now part of Danfoss Power Solutions) is a globally recognized manufacturer of hydraulic and hydrostatic components for mobile equipment. Their product line includes axial piston pumps, bent axis motors, hydrostatic transmissions, and control systems used extensively in construction equipment, agricultural machinery, material handling systems, and industrial applications. Sauer-Danfoss components are known for precision engineering, durability, and high power density in demanding operating environments.

Sauer-Danfoss engineers and manufactures advanced hydraulic drive systems and components for mobile machinery. Their core products include variable displacement pumps, fixed and variable motors, integrated transmission systems, electronic controls, and steering components. These systems provide the hydraulic power transmission that drives excavators, tractors, harvesters, mining equipment, and industrial machinery. Sauer-Danfoss solutions enable precise control, high efficiency, and reliable performance in applications ranging from agricultural implements to heavy construction equipment.

Standard Sauer-Danfoss pump rebuilds typically ship within 3 business days after receiving your core unit. The actual repair process involves complete disassembly, precision inspection of all components, machining or replacement of worn parts, reassembly with genuine Sauer-Danfoss seals and components, and comprehensive testing on calibrated test stands. For urgent situations, we offer exchange programs where a rebuilt unit ships immediately while your core is processed separately. On-site emergency repairs can often be completed same-day depending on component availability and failure severity.

All Sauer-Danfoss pump, motor, and transmission rebuilds include our comprehensive 1-year warranty covering parts and workmanship. This warranty protects against defects in remanufactured components and ensures your system performs to OEM specifications. The warranty is backed by our full money-back guarantee, demonstrating our confidence in the quality of our rebuilds. Coverage includes replacement or re-repair of any warranted component that fails due to workmanship or materials, with straightforward claim processes and rapid turnaround on warranty service.

Yes, we specialize in servicing legacy and discontinued Sauer-Danfoss product lines. Our extensive parts inventory and supplier network provide access to components for older Series 20, Series 40, Series 45, Series 51, and Series 90 pumps and motors. We maintain technical documentation and rebuild procedures for vintage Sauer-Danfoss systems, and our experienced technicians have worked with equipment spanning several decades. When original parts are unavailable, we can often source compatible alternatives or machine custom components to restore older units to full functionality.

We provide comprehensive exchange programs for most Sauer-Danfoss pumps, motors, and transmissions. Exchange service delivers a fully remanufactured unit immediately, minimizing your equipment downtime, while your original core is rebuilt for inventory. All exchange units are tested to OEM specifications and carry the same 1-year warranty as standard rebuilds. This option is particularly valuable during peak seasons or critical project deadlines when equipment downtime directly impacts productivity and revenue. Exchange availability depends on specific model numbers and current inventory levels.

We service the complete range of Sauer-Danfoss hydrostatic products including Series 20 motors and pumps, Series 40 axial piston units, Series 45 frame pumps, Series 51 bent axis motors, and Series 90 variable displacement pumps. Our capabilities extend to H1 hydraulic pumps, closed-circuit systems, and integrated transmission units. We also repair Sauer-Danfoss steering components, control valves, and auxiliary systems. Our technicians maintain current technical training on newer Danfoss Power Solutions products while preserving expertise in legacy Sauer-Danfoss lines no longer in production.

Sauer-Danfoss repair costs vary based on the specific component, extent of damage, and parts required. Factors influencing price include pump series and displacement, whether major components like cylinder blocks or valve plates need replacement, seal kit specifications, and any precision machining required. We provide free quotes after evaluating your unit or discussing symptoms and failure modes. Our pricing is transparent and competitive, typically offering significant savings compared to new OEM replacement while delivering equivalent performance and reliability backed by our 1-year warranty.
