Abstract:
A method of making a magnetic coupling driven pump comprising the steps of:providing a housing having an inlet and an outlet;operatively positioning a pumping mechanism inside the housing;operatively positioning a magnetic drive coupling proximal the pumping mechanism;operatively connecting the pumping mechanism to a drive mechanism; andmaking a magnetic barrier can having an open end and a closed end comprising the steps of:providing at least one mandrel;providing at least one spool piece;operatively connecting the at least one spool piece to the at least one mandrel;providing a winding machine having an axis;operatively connecting the at least one spool piece to the winding machine;providing a fiber coated with at least one resin;winding the resin coated fiber over the at least one mandrel and about the at least one spool piece to form the closed end of the can;operatively positioning a resistant temperature detector relative to the can such that the sensing area of the detector is located proximate the closed end of the magnetic barrier can;heat curing the resin coated fiber on the at least one mandrel; andremoving the heat cured resin coated fiber from the at least one mandrel such that the resulting finished can has about the inner dimensions and about the outer dimensions of the at least one mandrel and is resistant to deformation; andoperatively positioning the finished can within the magnetic drive coupling.
