High-Speed

High-speed gearboxes drive turbines, generators, hydroelectric units, large compressor trains, wastewater process equipment, and other mission-critical systems where failure has expensive consequences. Northwest Power Products handles OEM-spec repair and replacement across this category, with service experience covering turbine, generator, right-angle high-speed, helical, planetary, parallel shaft, and cylindrical gearboxes paired with AC and DC motors. The brand list spans Farrel, GE, Ingersoll Rand, Turbodyne, Worthington, Elliott, Terry, Lufkin, Falk, Westinghouse, Sumitomo, Foote-Jones, Renk Turbo Gear, Philadelphia Gear, David Brown Santasalo, and Cotta — current production and long-discontinued units alike.

What customers running high-speed equipment value most is honest scheduling and OEM-spec quality. We tell you the realistic rebuild window up front, source OEM parts where production is still active, reverse-engineer when it is not, and run field service for in-place inspection and minor repair on units where pulling the gearbox is impractical. For replacements we cross-reference legacy units to current Falk, Sumitomo, or Foote-Jones equivalents, confirming torque rating, ratio, and shaft configuration before quoting.
