POSSIBLE CAUSES
A. Power supply disconnected
B. Make sure the engine is fed
C. Defective engine.
A. Make sure the feed voltage corresponds to the one on
the plate.
B. Check that the joints are made correctly.
C. Check the voltage input to the table and in the terminal
box the presence of all phases.
D. The shaft is blocked, look for possible blockages of the
pump or engine.
A. Verify the feed voltage which may be insufficient.
B. Check for possible friction between moving and fixed
parts.
C. Check the status of the bearings.
A. Verify that the ambient temperature is not too high.
B. Verify the calibration of protection.
C. Check the status of the bearings.
D. Check the rotational speed of the engine.
A. The pump has not been properly set.
B. Verify the correct direction of rotation of the three-
phase engines.
C. Ramp of aspiration is unevenly high.
D. Suction pipe with an insufficient diameter or too high
for a long extension.
E. Bottom valve clogged.
A. The suction pipe or the bottom valve, suck air.
B. The negative suction tube placement favors the
formation of air blisters.
A. Bottom valve clogged
B. Turbine worn-out or clogged.
C. Suction pipes of insufficient diameter.
D. Check the correct direction of rotation.
A. Suction pressure too low.
B. Suction tube or pump partially clogged with impurities.
A. No oil.
B. Oil transmitter is damaged.
A.Obstruction of the engine's cooling circuit.
A. Faulty mechanical seal.

C. Replace the damaged bearings.
A. Ventilate properly the room where
the pump is installed.
B. Perform the calibration with a proper
voltage value for the absorption of
the engine in full load.
C. Replace the damaged bearings.
A. Fill the pump and the suction pipe
with water and start the priming.
B. Revert between two power cables.
C. Refer to section 8 for the
"Installment" instructions.
