Hydro Governor Solutions
Legacy Spare Parts
Mechanical governors have longer mean-time-between-failure than digital controllers. Keep your legacy units operating like new, providing precise frequency control, with support from Emerson’s trusted experts for tuning, calibrating, or overhauling your governor system.
Our knowledgeable team provides field service and training for every governor make and model. We maintain an extensive inventory of hard-to-find new and refurbished parts to get your unit quickly back online and operating reliably.
Training
With hydro plant staffing in constant flux, governor training is more important than ever, especially for legacy systems.
We offer a variety of training options to meet your needs, including on-site, factory, or virtual classes.
Unlike textbook-only classes we offer hands-on sessions with real, operating equipment, including complete working examples of governors and pumps as well as many unique and instructive cutaway assemblies.
