For many reasons, variable frequency drives represent the next evolution in the increasingly demanding residential water well pump market. Since the invention of the first submersible motor for water well systems, the 4-inch encapsulated motor has proven to be the industry’s most trusted driving force behind residential pumping systems. However, some people working today may not realize just how skeptical folks were back then about running an electric motor underwater.
Today’s innovations, like VFDs, can suffer from the same kind of unfamiliarity. Yet, by enhancing residential water pumping systems with efficient VFD solutions, customers can save money and energy, and add reliability. For starters, a single unit of variable frequency drives can give you the flexibility to cover various size ranges while delivering built-in pump and motor protection. While 2-horsepower jobs and under are the typical requirement at residential settings, today’s existing solutions can help you address jobs for any pumping challenge. A benefit of VFDs with phase conversion is that you can run three-phase motors using residential single-phase power. Even without a three-phase motor installed in the well, you can replace most single-phase three-wire control boxes with this drive, and then upgrade the motor later.
