SUBMERSIBLE PUMP PROTECTION FOR HOSTILE ENVIRONMENTS

摘要

The present invention is directed to the protection of submersible electric pump motors against hostile environments involving corrosive, abrasive and erosive fluids. The invention includes an elastomeric boot or sleeve which substantially envelops the motor and which is sealed at its mouth to the periphery of the motor at one end. The interior of the boot between the motor and the boot wall is substantially filled with a heat transfer fluid such as ethylene glycol or a mixture of same and water.
