1. The pump has no water or proper venting. Elimination: Check that the pump housing and inlet line are completely filled with liquid.
2. The speed is too low Elimination measures: Check the wiring of the motor is correct, the voltage is normal or the steam pressure of the turbine is normal.
3. The head of the system is too high to eliminate measures: Check the system's head (especially friction loss).
4. Suction lift too high Eliminate measures: Check the existing net head (too small or too long inlet line will cause great friction loss).
5. Impeller or pipeline blockage elimination measures: check for obstacles.
6. The direction of rotation is not corrective: Check the direction of rotation.
7. Air generation or inlet line leak elimination measures: Check the inlet line for cavitation and/or air leakage.
8. The packing or seal in the stuffing box is worn so that air leaks into the pump casing. Elimination measures: Check the packing or seal and replace it as needed. Check if the lubrication is normal.
9. Inspiratory suction head when pumping hot or volatile liquids Elimination: Increase the suction head and consult the Atlantic pump industry.
10. The bottom valve is too small. Elimination: Install the correct size bottom valve.
11. Insufficient immersion depth of bottom valve or inlet tube. Elimination: Inquire Atlantic Pumps for correct immersion depth. Use baffles to eliminate eddy currents.
12. Too much impeller clearance Elimination: Check that the clearance is correct.
13. Impeller damage elimination measures: Check the impeller and replace it as required.
14. Impeller diameter too small Elimination: Ask the Atlantic pump industry for the correct impeller diameter.
15. The gauge is incorrectly positioned. Eliminate measures: Check that the position is correct and check the outlet nozzle.
