    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.
