Pump Sizing And Performance; Generator Sizing - Franklin Electric MONODRIVE UTILITY Manuel Du Propriétaire

Pump Sizing and Performance

Maximum pump output using the MonoDrive Utility 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.
NOTE: MonoDrive Utility may result in 85-90% of pump performance when compared to other
MonoDrive/MonoDriveXT models, especially in applications with reduced input voltage.
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
components are in good working order, no further system upgrades are required. However, if the
existing pump and motor have not been properly chosen, or if the components of the well system
are not in good working order, the MonoDrive Utility cannot be used to correct the problem or
extend the life of aging components.

Generator Sizing

Basic generator sizing for the Franklin Electric MonoDrive Utility is 1.5 times the maximum input
watts consumed by the drive, rounded up to the next normal-sized generator.
Recommended minimum generator sizes for the MonoDrive Utility:
• 3500 watts nominal for up to 1 HP
• 5000 watts nominal for up to 2 HP
IMPORTANT: Do not use with a Ground Fault Circuit Interrupter (GFCI). If using an externally regu-
lated generator, verify that the voltage and hertz are appropriate to supply the drive. Not recom-
mended for use with invert-controlled generators or AC-DC inverters.
