Insufficient discharge
Pump stopped
The pump is not delivering
Flowrate too low or insufficient
pressure
Irregular Flowrate
8. Trouble shooting
Grounds
Electricity is not supplied
Vanes are blocked
The filter is not immersed into liquid
There is not liquid into the body of the pump
There is air at intake
The filter is very dirty
You have exceeded the maximum
Intake too deep
Clogged filter
The level of the liquid falls quickly
flow reduced by a foreign matter
Diameter of intake pipe insufficient
Motor is overloaded due to excessive friction
Inadequate voltage
The gate is closed on the circuit
Wrong priming of the pump
Air intake
Footvalve not into liquid point in the inlet pipe
(airpocket created)
No rotation of the electropump
Aspiration head too high
Stuck or blocked footvalve
Tap or gate partially closed
Obstructed pump or piping,
introduction of foreign body
Exaggerated Pressure differences
Insufficient rotation speed
Aur intake
Bad electrical operation
Solve
Check if voltage is appropriate, if electrical
connections are right and if the fuse is not
burnt.
Dismantle pump body and clean up the inside
part
Immerse the filter into the liquid
Fill the intake pipe and the body
Make sure of the tightness of the connections
Clean the filter
Check the depth intake height
Check the depth
Clean the intake pipe, the pump and the
filter, avoid the aspiration of particles
Place the intake pipe lower (10 cm higher
than lowest level)
Clean the body of the pump and the impellers
Fit a suitable pipe
Dismantle and clean the pump. Avoid to draw
in foreign matters.
Check the power supply, the power cable and
make sure the cable is not too long and that
the cross section is proper.
check up
review the boot process (paragraph 3.4 Use)
Check connections of suction (see section 3.4
use)
Submerge it deeper
Modify the aspiration pipe
Consult your electrician or dealer
Lower the level of the pump or the place
closer to the tank or vessel
Check, clean or change
Open it more widely
Check, clean
Bad quality of the inlet piping
Non-conform piping (diameter, length)
Non-conform component (nozzle)
Use piping with a wider diameter
Change the motor-pump group
Check with an electrician or the distributor
Check for air intakes on the inlet pipe
Immerse the footvalve more deeply
Check with an electrician
