Franklin Monodrive variable speed constant pressure controllers are designed to provide constant pressure for 1-1/2 HP or 2 HP 230 volts, single-phase, three-wire submersible water well pump systems. You can have constant pressure just by replacing the three-wire control box in a conventional system.

Ideal for applications where constant pressure is desirable: residential water systems, landscaping, water treatment and geothermal applications.

The MonoDriveXT ( 1-1/2 HP or 2 HP) is designed to convert a conventional pump system to a variable speed constant pressure system by simply replacing the 3-wire control box and pressure switch. Maximum pump output using the MonoDrive is similar to the performance achieved using a conventional control box. Therefore, the pump selection criteria are the same as if a control box were used.
