Never miss a beat

  There are mainly four reasons that cause canned motor pump can not pump water

  1. Water or air leakage in the pipeline: The nut may not be tightened tightly during installation. If the leakage is not serious, apply cement or cement slurry mixed with asphalt oil on the leaking or leaking place. Serious water leakage must be re-disassembled.

  2. The water circulator pump vibrates severely: The impeller and rotor may be unbalanced, or the coupling may be poorly coupled, and the bearing may be worn and bent; it may also be loose or cracked in some rotating parts; maybe it is because the pipeline support is not firm. Measures such as adjustment, repair, reinforcement, and replacement can be taken separately.

  3. During installation, the inlet and outlet directions are reversed or the motor wiring is incorrect. The rotation direction of the pump is incorrect.

  4. Not filled with water or the air in the inlet pipe is not cleaned : Continue to fill the water or purge the air in the inlet pipe.
