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.
