What is a SubDrive?

SubDrive is Franklin Electric's family of constant pressure controllers. 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.

SubDrive QuickPAK is Franklin’s newest system solution package, designed to make installing a constant pressure system even easier.
