Our Training and Repair Facility offers repair services for major governor auxiliary systems like XX Herringbone Gear Pumps and Permanent Magnet Generators. We can repair nearly any damaged or broken governor component.
Factory repairs save you money, as opposed to sending a technician to your site, and allows us to perform additional services that are difficult or impossible to do in the field.
