ABSTRACT:
A bubble trap for a submersible pump is provided that is placed above the stator assembly of the motor and within sealant material located around the coils of the motor. The bubble trap helps prevent moisture from working its way throught the sealant material through the coils by traveling through bubbles in the sealant material. The bubble trap improves product safety and quality and reduces production rejects, thereby improving production time and efficiency.
