Structures Of Non-Positive Displacement Pumps

Abstract
An improved centrifugal pump, which is essentially characterized by being the carrier shaft of the impeller or turbine wedged to a cylindrical magnet coaxial with the shaft, the assembly being enclosed in a chamber through which no leakage of the liquid is possible, as it is said sealed chamber, and by the existence of a second magnet disposed outside said chamber and coaxially with the cylindrical magnet it surrounds, the external magnet being coined on an axis in such a way that, when rotating, the magnetic flux of the external magnet pulls in its rotation movement to the magnet-cylindrical that surrounds.
