Pump Sizing and Performance
Maximum pump output using the drive is similar to the performance achieved using a pressure switch.
Therefore, the pump selection criteria are the same as if a pressure switch were used.
Refer to the Franklin Electric AIM Manual for specific sizing information.
If a pump and motor as described above are already installed in the system, and the well system compo
-
nents are in good working order, no further system upgrades are required. However, if an existing pump and
motor have not been properly evaluated, or if the components of the well system are not in good working
order, the drive cannot be used to correct the problem or extend the life of aging components.
Generator Sizing
Basic generator sizing for the drive is 1.5 times the maximum input watts consumed by the drive, rounded
up to the next normal-sized generator.
Recommended minimum generator size for the SubDrive Utility is 6000 watts nominal.
IMPORTANT:
Do not use with a Ground Fault Circuit Interrupter (GFCI). If using an externally regulated gen
-
erator, verify that the voltage and hertz are appropriate to supply the drive. Not compatible with inverter-
controlled generators.
