Abstract
An electric submersible pump and motor assembly for downhole applications has an electric motor having a stationary nonrotating through bore, a pump driven by the electric motor, a deployment line upon which the electric motor and pump may be lowered down through a production tube, and a seal for sealing the assembly against the production tube. An inlet upstream of the seal through which well bore fluid may flow extends through the pump and the stationary nonrotating through bore of the motor, and the fluid may exit through an outlet open to the well bore downstream of the seal.
