Abstract
The present invention provides an electric submersible pumping assembly that includes an encapsulated pumping device containing a pump, an electric submersible motor, a sealing device at the top, and an opening device at the bottom. The lubricant-filled, initially sealed, encapsulated pumping device allows the pump and motor to be run in the wellbore without contamination and be left intact until operated.
