Franklin Monodrive Variable Speed Constant Pressure Controller

Franklin Monodrive variable speed constant pressure controllers provide constant pressure for 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 MonoDrive (1/2, 3/4 or 1 HP) and the MonoDriveXT ( 1.5 or 2 HP) convert a conventional pump system to a variable speed constant pressure system by simply replacing the 3-wire control box and pressure switch. The maximum pump output using either control 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.
