Care must be taken to size and run a pump used in a
fountain application as close to its Best Efficiency Point
(BEP) or middle of the impeller curve as possible.
If a pump is allowed to run "open", meaning with very
low total dynamic head, or on the far right side of the
impeller curve (or so far right it isn't even on the curve!),
the pump is drawing maximum amps. This may even be

higher than the full load maximum amps specification
for the motor. This causes overheating of the motor and
drastically decreased motor life.
If the pump is on the far right of its curve, a valve can be
installed on the discharge pipe and partially closed to cre-
ate needed pressure that will move the flow back closer
to the BEP for the impeller curve. A flow meter can tell
you what that is, or an amp reading
can tell you as well. The maximum
amps on our published pump curve
bulletins or pump nameplate are just
that, the maximum amps the motor
should be drawing.
We recommend taking an amp read-
ing and/or a flow reading at initial
startup. If the amp reading is too

high, partially close the valve until
the reading falls back to slightly less
than or equal to maximum amps.
This action causes the pump to run
on our published curve to which is
has been tested. It is also imperative
to run a pump in a continuous duty
application fully submerged.
