An assembly for downhole applications comprises an electric motor, a pump driven by the electric motor, the assembly being suspended from and lowered through the well on a deployment tube, the electric motor and the pump both being hollow such that a bore passes from the tube past the motor and the pump opening at the bottom of the assembly such that a device suspended on a wireline may be lowered through the deployment and pass through the electric motor and pump.
