SubDrive & MonoDrive NEMA 4
SubDrive & MonoDrive NEMA 4
Constant Pressure Variable Frequency Drives (VFD)
From residential to agricultural and commercial applications, Franklin Electric’s SubDrive family of variable frequency drives (VFDs) offer a cost-effective, easy-to-install upgrade to traditional systems.
Designed within a NEMA 4 weatherproof enclosure, they offer rugged, watertight variable frequency drive solutions that meets water demand changes.

SubDrive NEMA 4
SubDrive75, SubDrive100, SubDrive150, and SubDrive300 controllers are designed for three-phase motors to provide constant pressure with three-phase performance using single-phase input power for 1-1/2 – 5 hp jobs.
MonoDrive and MonoDrive XT NEMA 4
MonoDrive and MonoDriveXT are designed to convert a conventional ½ hp to 2 hp pump system to a variable speed constant pressure system by simply replacing the 3-wire control box and pressure switch.
