Pump Sizing – SubDrive150
The SubDrive150 is configured at the factory for use with 1.1 kW pumps that are mounted to 2.2 kW
Franklin Electric three-phase motors.
In general, the SubDrive150 will enhance the performance of a
1.1 kW pump to a similar or better performance than a conventional 2.2 kW pump of the same flow
rating (pump series).
Serious or fatal electrical shock may result from contact with internal electrical components. DO NOT, under any
circumstances, attempt to modify DIP switch settings until power has been removed and 5 minutes have passed for
internal voltages to discharge! Power must be removed for DIP switch setting to take effect.
Drive Configuration
The SubDrive150 can also be set up to run a 1.5 kW
or 2.2 kW pump if desired, but larger pumps will still
produce to the 2.2 kW curve and may only be operated
with a 2.2 kW motor. To operate a different pump size,
a DIP switch must be positioned to select the correct
pump rating. Otherwise, the SubDrive150 may trigger
erroneous faults.
To configure the SubDrive150 for a 1.5 kW or 2.2 kW
pump, locate the DIP switch marked “SW1”. Use a small
screwdriver (provided) to change the DIP switch setting
according to the chart as shown.

DANGER
To select the proper 1.1 kW pump, first choose
a 2.2 kW curve that meets the application’s
head and flow requirements. Use the 1.1 kW
pump in the same pump series (flow rating). The
SubDrive150 will adjust the speed of this pump
to produce the performance of the 2.2 kW curve.

pump curve for your specific application.
