The liquid being
pumped may
be too thick. Contact your local Reece branch. You may need
a different type of pump for the application.
This pump is for clean, debris free water only.
There may be
rotation resistance
in the pump fan. 1. Disconnect all electrical power.
2. Remove the fan cover.
3. Rotate the fan by hand and
it should rotate freely.
There may be
cavitation in the pump
(demand for water
is higher than it
can pump).
* Cavitation can be
identified by the noise
of the pump. You
will hear a bubbling,
crackling sounds like
marbles rattling inside
the pump casing.
The length of the suction pipe may be too long,
or the internal diameter may be too small:
1. Reduce either the suction
height or distance.
2. Increase the suction pipe internal diameter
to same size as the pump inlet or larger.
There may be
excessive liquid
temperature. The liquid temperature should be below 40°C.
Check liquid temperature using a thermometer.
The pump motor
thermal cut out
protection setting,
or fuses may not
be suitable. Check protection devices with respect
to rated current of pump. The circuit
breaker should be rated to 10A.
The pump power cable
may be damaged. Replacement parts required. Contact a pump
technician or call your local Reece branch.
The pump motor
may be damaged. There may be resistance in the pump motor shaft.
1. Disconnect all electrical power.
2. Remove pump casing and check for objects
jammed between moving components.
3. If still jammed, or damaged, replacement
parts required. Contact a pump technician
or call your local Reece branch.
