In general, the
SubDrive300 will enhance the performance of a 3 Hp pump to a similar
or better performance than a conventional 5 Hp pump of the same
fl owrating (pump series).
or better performance than a conventional 5 Hp pump of the same
fl owrating (pump series).
To select the proper 3 Hp
pump, fi rst choose a 5 Hp
curve that meets the
application’s head and fl ow
requirements. Use the 3 Hp
pump in the same pump
series (fl ow rating). The
SubDrive300 will adjust the
speed of this pump to
produce the performance
of the 5 Hp curve. An
example of this is
illustrated in the graph at right.

Drive Confi guration
The SubDrive300 can also be set up to run a 5 Hp pump if desired, but the
larger pump will still produce to the 5 Hp curve and may only be operated
with a 5 Hp motor. To operate a different pump size, a DIP switch must be
positioned to select the correct pump rating. Otherwise, the SubDrive300
may trigger erroneous faults.
