സാധാരണ സബ്‌മെർസിബിൾ പമ്പ് പ്രശ്‌നങ്ങളും പരിഹാരങ്ങളും

Possible causes:

• No power or tripped MCB — check supply and control panel
• Low voltage — use stabilizer; motors need rated voltage
• Cable fault or loose joint — inspect cable from panel to pump
• Dry run protection activated — verify water level in borewell

Solution: Restore power, fix cable joints, ensure adequate water level, then restart. If motor hums but does not spin, contact authorized service.

Possible causes:

• Water level dropped below pump intake
• NRV (non-return valve) stuck or leaking
• Pipeline leak or air lock in delivery pipe
• Impeller choked with sand or debris
• Wrong pump depth setting

Solution: Check water level, inspect NRV and pipes, clean strainer, verify pump is submerged correctly. A complete system inspection restores flow.

Possible causes:

• Partially blocked strainer or pipeline
• Increased pipe friction from undersized pipe
• Worn impeller or declining water table
• Pump operating below rated voltage

Solution: Clean strainer every 3–6 months, verify pipe diameter matches pump capacity, test voltage at panel, and reassess HP if water table has fallen significantly.

Possible causes:

• Overload relay set too low
• Single phase failure on three phase supply
• Mechanical binding or sand ingress
• Pump oversized for borewell yield (cycling)

Solution: Check all three phases, reset overload correctly, inspect for sand damage, and confirm pump HP matches borewell capacity with your dealer.

Possible causes:

• Pump hitting borewell wall during installation
• Loose mounting or worn bearings
• Cavitation from insufficient submergence
• Electrical imbalance

Solution: Ensure central alignment in borewell, maintain minimum submergence as per guidelines, schedule dealer inspection for bearing or mechanical wear.

Contact your nearest authorized കിംഗ്വെൽ dealer if:

• Motor burns repeatedly after repair attempts
• Water flow suddenly stops after years of normal use
• Warranty repair is needed
• Pump needs pulling and inspection from borewell
