SubDrive Utility

View this video to learn the simple installation process for the SubDrive Utility.

The Franklin Electric SubDrive Utility is a variable frequency drive (VFD) designed to control and protect 2-wire, single-phase motors with 115 or 230 Volt ratings, enhancing pump performance for residential and light commercial water system applications. When used with Franklin Electric motors ranging from 1/3 to 1 1/2 HP, the SubDrive Utility drives a motor and pump at variable speeds to maintain constant water pressure, even as user demands (water flow) change.

The SubDrive Utility is also compatible with single-phase 2-wire submersible split capacitor (PSC) motors, above-ground booster pumps, and jet pumps with overload current ratings from 4.6 A to 13.1 A.

The SubDrive Utility is designed to convert a conventional pump system to a variable speed constant pressure system by simply replacing the pressure switch.
