How it Works
The Franklin Electric SubDrive/MonoDrive is designed to be part of a system that
consists of only four components:
A. Standard Pump and Franklin Electric Motor
B. SubDrive/MonoDrive Controller
C. Small Pressure Tank (see Table 4, pg. 29)
D. Franklin Electric Pressure Sensor (NSF 61 rated (provided))
E. Pressure shut-off switch (NSF 61 rated (SubDrive300 only))
Constant Pressure
The Franklin Electric SubDrive/MonoDrive provides consistent pressure regulation using
advanced electronics to drive a standard motor and pump according to the pressure
demands indicated by a highly accurate, heavy-duty, long-life pressure sensor. By
adjusting the motor/pump speed, the SubDrive/MonoDrive can deliver constant pressure
dependably, even as water demand changes. For example, a small demand on the
system, such as a bathroom faucet, results in the motor/pump running at a relatively
low speed. As greater demands are placed on the system, such as opening additional
faucets or using appliances, the speed increases accordingly to maintain the desired
system pressure.
