Page 7: How It Works
SubDrive/MonoDrive 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. - Page 8 MonoDrive and a pressure sensor. If the existing pump, motor and pressure tank are in good working order, no further changes are needed. MonoDrive controllers are ideal whenever the Franklin Electric single-phase 3-wire series motor is preferred. MonoDrives are especially suited for retrofit applications where a 3-wire pump system is already installed and in good operating condition.

Flow GPM The SubDrive75 can also be set up to run a 1.0 hp (0.75 kW) or 1.5 hp (1.1 kW) pump if desired, but larger pumps will still produce to the 1.5 hp (1.1 kW) curve and may only be operated with a 1.5 hp (1.1 kW) motor. -
Page 10: Subdrive100
The SubDrive100 is configured at the factory for use with 1.0 hp (0.75 kW) pumps that are mounted to 2.0 hp (1.5 kW) Franklin Electric three-phase motors. In general, the SubDrive100 will enhance the performance of a 1.0 hp (0.75 kW) pump to a similar or better performance than a conventional 2.0 hp (1.5 kW) pump of the same flow rating (pump series). -
Page 11: Subdrive150
The SubDrive150 is configured at the factory for use with 1.5 hp (1.1 kW) pumps that are mounted to 3.0 hp (2.2 kW) Franklin Electric three-phase motors. In general, the SubDrive150 will enhance the performance of a 1.5 hp (1.1 kW) pump to a similar or better performance than a conventional 3.0 hp (2.2 kW) pump of the same flow rating (pump series). -
Page 12: Subdrive300
The SubDrive300 is configured at the factory for use with 3.0 hp (2.2 kW) pumps that are mounted to 5.0 hp (3.7 kW) Franklin Electric three-phase motors. In general, the SubDrive300 will enhance the performance of a 3.0 hp (2.2 kW) pump to a similar or better performance than a conventional 5.0 hp (3.7 kW) pump of the same flow rating (pump series). -
