Yes, variable frequency drives and hydrostatic drives can often be repaired rather than replaced, depending on the extent of damage. At Hydrostatic Transmission Service, our technicians assess each Danfoss unit thoroughly—rebuilding, testing, and calibrating components to manufacturer specifications. Repairing rather than replacing is typically faster and more cost-effective, and all rebuilt units come with a full 1-year warranty.
What is the life cycle of a Danfoss drive?
With proper maintenance, Danfoss hydrostatic drives can deliver reliable performance for many years. Life expectancy depends on operating conditions, load cycles, fluid cleanliness, and maintenance intervals. When a drive approaches the end of its service life—or fails prematurely—a professional rebuild to manufacturer specifications can restore full performance and effectively extend the unit's operational life at a fraction of replacement cost.
Which Danfoss hydrostatic series do you service?
