SubDrive is Franklin Electric’s family of constant pressure controllers which includes MonoDrive, SubDrive 75, SubDrive 150, and SubDrive 300, covering a range from ½ to 5 Hp. SubDrive controllers provide constant pressure by continually monitoring and adjusting the pump speed to meet water supply demands. SubDrives also eliminate pressure cycling during long-running applications such as landscape irrigation and geothermal heat pump operation. All in all, SubDrives combine reliability and state-of the art technology to provide well owners with a premium water system.
What is MonoDrive?
MonoDrive is the biggest technological advance in the constant pressure arena. MonoDrive is designed to provide constant pressure for singlephase, three-wire systems—even those already in place. That means you can have constant pressure just by replacing a three-wire control box!
