P
Problem
Cause and solution
The pump does
not start.
• The thermo-overload protection in the single-
phase motor has tripped; it will automatically
reset when the motor cools down.
• Check the power supply wiring to see that the
connections are all tight
• Check to see that the circuit breaker or ground-
fault protection device has tripped. Or replace
any fuses that may have blown.
• Check to see if any protection device installed
for dry running protection has tripped or hung
up.
The pump starts
up but the ther-
mal protector is
triggered after a
short time or the
fuses blow.
• The power supply cable is damaged, the motor
short circuits or thermal protector or fuses are
not suited for the motor current. Check and re-
place the components as necessary.
• The thermo-overload protection (single phase)
or of the protection device (three-phase) trips
due to excessive current input. Check the
pump working conditions.
• A phase in the power supply is missing. Check
the power supply.
• The pump is clogged with solids and the impel-
ler becomes bound. Clean the pump.
The pump starts
but does not de-
liver any liquid.
• Air is entering the suction piping, check the liq-
uid level, the tightness of the suction pipes and
the operation of the foot valve.
• The pump is not correctly primed. Repeat the
instructions in
Prime the pump
(page 5).
The pump’s de-
livery is re-
duced.
• Check for restrictions in the piping system.
• Wrong rotation of the impeller (three-phase).
Check the direction of rotation.
• The pump is not correctly primed. Repeat the
instructions in
Prime the pump
(page 5).

with the specifications referred to in the quotation or sales form, if such
specifications are expressly made a part of this Agreement, and (ii) free

days after receipt of notice that the goods are ready to ship), whichever
shall occur first, unless a longer period is specified in the product docu-
mentation (the “Warranty”).
