Troubleshooting Chart
Risk of electric shock. Always disconnect the pump from the power source before handling inspections or repairs.
Symptom Possible Cause(s) Corrective Action
Little or no discharge and will not prime
NOTE:

than at Barmesa Pumps or its authorized service centers, automatically voids warranty.
1. Pump body not filled with water
2. Total head too high
3. Suction head higher than pump designed for
4. Impeller partially or completely plugged
5. Leak in suction line
6. Foot-valve too small
7. Impeller damaged
8. Foot-valve or suction line not submerged deep
enough in water, pulling air
9. Insufficient inlet pressure or suction head
10. Suction piping too small
11. Body gasket leaking
12. Suction or discharge line valves closed
13. Piping damaged
14. Clogged strainer or foot-valve
Loss of suction after satisfactory operation
1. Air leak in suction line
2. When pump was last turned off, water siphoned
out of pump body
3. Suction head higher than pump designed for
4. Insufficient inlet pressure or suction head
5. Clogged foot-valve, strainer or pump
6. Defective wearplate
1. Total head lower than pump rating, unit delivering
too much water
2. Specifi c gravity and viscosity of liquid being
pumped different than the pump rating
Pump overloads driver
Pump vibrates and/or makes excessive noise
1. Mounting plate or foundation not rigid enough
2. Foreign material in pump causing unbalance
3. Impeller bent
4. Cavitation present
5. Piping not supported to relieve any strain on
pump assembly
Pump runs but no fluid
1. Air leak in suction piping
2. Pump located too far from fluid source
3. Gate valve closed
4. Clogged strainer
5. Fouled foot-valve
6. Discharge height too great
7. Fouled impeller
8. Faulty mechanical seal
Pump leaks at shaft
1. Worn mechanical seal
2. Seal not installed properly
1. Fill pump body with water.
2. Shorten suction head
3. Lower suction head, install foot-valve and prime
4. Disassemble pump and clean out impeller
5. Repair or replace suction line
6. Match foot-valve size to piping or install one larger
size foot-valve
7. Disassemble pump and replace impeller
8. Submerge lower in water
9. Increase inlet pressure by adding more water to
tank or increasing back pressure by turning gate
valve on discharge line partially closed.
10. Increase pipe size to pump inlet size or larger
11. Replace
12. Open
13. Clean or replace
14. Clean or replace
1. Repaire or replace suction line
2. Refill (reprime) pump body before restarting
3. Lower suction head, install foot-valve and prime
4. Increase inlet pressure by adding more water to
tank or increasing back pressure by turning gate
valve on discharge line to partially closed.
5. Unclog or replace
6. Replace
1. Increase back pressure by turning gate valve on
discharge line to partially closed position that will
not overload motor.
2. Consult factory
1. Reinforce
2. Disassemble pump and remove
3. Replace impeller
4. Check suction line for proper size and check valve
in suction line if completly open, remove any sharp
bends before pump and shorten suction line
5. Make necessary adjustments
1. Replace
2. Replace
3. Open
4. Clean or Replace
5. Clean or Replace
6. Lower the height
7. Clean or Replace
