  • Patent number: 11459869
    Abstract: Disclosed is an apparatus when installed with an Electrical Submersible Pump for fluid production protects the motor from the effect of solids on the shaft seal. The invention provides an apparatus that dynamically filters the solids and prevents them from contacting or accumulating at the vicinity of the shaft seal. The apparatus extends the run life of the ESP and prevents the motor dielectric fluid from being contaminated.
