SubDrive30
The SubDrive30 is capable of use with 1.5 hp (1.1 kW) pumps that are mounted to
3.0 hp (2.2 kW) Franklin Electric three-phase motors. In general, the SubDrive30 will
enhance the performance of a 1.5 hp (1.1 kW) pump to a similar or better performance
than a conventional 3.0 hp (2.2 kW) pump of the same flow rating (pump series).
To select the proper 1.5 hp
(1.1 kW) pump, first choose
a 3.0 hp (2.2 kW) curve that
meets the application’s head
and flow requirements. Use
the 1.5 hp (1.1 kW) pump
in the same pump series
(flow rating). The SubDrive30
will adjust the speed of
this pump to produce the
performance of the 3.0 hp
(2.2 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 SubDrive30 can also be set up to run a 2.0 hp (1.5 kW) or 3.0 hp (2.2 kW) pump if
desired, but larger pumps will still produce to the 3.0 hp (2.2 kW) curve and may only be
operated with a 3.0 hp (2.2 kW) motor. To operate a different pump size, a DIP switch must
be positioned to select the correct pump rating. Otherwise, the SubDrive30 may trigger
erroneous faults.
See the Basic Setup section of this manual for DIP switch information and settings.
