Pump Sizing and Performance

SubDrive15

The SubDrive15 is capable of use with 3/4 hp (0.55 kW) pumps that are mounted to
1.5 hp (1.1 kW) Franklin Electric three-phase motors. In general, the SubDrive15 will
enhance the performance of a 3/4 hp (0.55 kW) pump to a similar or better performance
than a conventional 1.5 hp (1.1 kW) pump of the same flow rating (pump series).
To select the proper 3/4 hp
(0.55 kW) pump, first choose
a 1.5 hp (1.1 kW) curve that
meets the application's head
and flow requirements. Use the
3/4 hp (0.55 kW) pump in the
same pump series (flow rating).
The SubDrive15 will adjust the
speed of this pump to produce
the performance of the 1.5 hp
(1.1 kW) curve.
An EXAMPLE of this is
illustrated in the graph at
right. Please consult the pump
manufacturer's pump curve for
your specific application.
The SubDrive15 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. To operate a different pump size, a DIP switch must
be positioned to select the correct pump rating. Otherwise, the SubDrive15 may trigger
erroneous faults.
See the Basic Set-up section of this manual for DIP switch information and settings.

WARNING
!
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.
