a safety cable.
Fig. 13. Operate the pump within the rated working limits.
8. MAINTENANCE
Make sure the pump is unplugged or, for three-phase
pumps, that the main switch is disconnected before car-
rying out any maintenance operations.
4" and 5" pumps do not require any routine maintenance.
Periodically check the delivery pressure and the current
absorption.
A delivery pressure decrease may be caused by pump
wear.
Increased current absorption indicates abnormal mecha-
nical fiction in the pump or motor.
9. TROUBLESHOOTING
Possible causes and remedies
THE PUMP DOES NOT DELIVER.
• The water level has dropped. Wait for the level to be
restored.
• No power, the automatic switch has tripped.
Find the problem and reset the switch.
• Blown fuses (three-phase pump). Replace the fuses.
• Thermal protection activation. Reset the protection (For
5" pumps, it will reset automatically after the motor has
cooled).
• Clogged check valve.
• Sand in the pump. Extract the pump and have it overhau-
led.
REDUCED CAPACITY AND PRESSURE.
• Sand in the pump. Extract the pump and have it overhauled.
• Three-phase pump rotates in the wrong direction. Switch
two phase conductors in the control panel
• System leaks. Locate the leaks and repair them.
• Worn pump. Extract the pump and overhaul it.
THE PUMP STARTS AND STOPS TOO FREQUENTLY.
• Probable activation of level probes/float (pump capacity
higher than well capacity). Reduce water supply to the
user.
• Application with surge tank: pressure switch not set cor-
rectly or surge tank of inadequate capacity or insufficient
water cushion. Adjust the setting. Replace the tank with
one of greater capacity.
• Excessive absorption of current by the motor. Mechani-
cal friction. Extract the pump and have it overhauled.
• Liquid temperature too high (GSC single-phase).
Activation of the built-in motor protector.
