Structures Of Non-Positive Displacement Pumps

Abstract
An improved submersible pump, of the vertical shaft type, which is characterized by the arrangement of a moisture-insulating cylinder, but not electromagnetic force fields, said cylinder being placed as a sheath on the rotor of the built-in electric motor of the pump and between it and the stator, the sealing being guaranteed by two rubber O-rings placed on the upper and lower plates of the engine.
