POSSIBLE BREAKDOWNS, CAUSES AND SOLUTIONS
PROBLEMS CAUSES SOLUTIONS
Air entry in suction tube
Check pipe fittings and suction
tube joints
Bad filter cover sealing
Clean the pre-filter cover and
check the condition of the joint
THE PUMP DOES NOT PRIME
Motor turning direction incorrect.(III)
Invert two phases of the feeding
line
Blocked pre-filter
Clean the pre-filter
Air entry in suction tube
Check pipe fittings and suction
tube joints
Motor turning direction incorrect.(III)
Invert two phases of the feeding
line
Load loss in suction
Prevent as much as possible,
elements that produce load loss
THE PUMP GIVES LOW FLOW
Wrong voltage
Check that the network voltage
corresponds to that on the motor
specification board
Increase in terminal box
temperature because of voltage
arch effect
Check terminal box connections
Heat protector blows
Correctly connect cables with
terminal box terminals
Fasten the cable to the terminal
correctly
THE MOTOR STOPS
Terminal boxes badly connected
Modify size of connection cable to
terminal box terminals
