Impeller for a Magnetic Pump and Novel Impeller Housing Design

Abstract

The invention is the combination of a magnetically driven pump, with a motor and a basin, where the motor and pump mount on opposite sides of a mounting plate through an opening in the sidewall of the basin. Mounting plate properly aligns the driven magnet in the pump with the driving magnet on the motor.

1 . A magnetic driven pump and motor, in combination with a basin comprising:
 a basin adapted to hold a fluid, said basin having a aperture therethrough   a motor having a motor housing, a central shaft, and a driving magnet rotationally mounted to said central shaft, said motor housing further including a mounting face;   a mounting plate, said mounting plate having an interior face and an exterior face, said mounting plate adapted to be mounted to said mounting face of said housing through said aperture of said basin, said mounting plate further comprising a mount member positioned on said exterior face,   a pump body having a pump housing, having an interior, and a driven magnet positioned in said pump housing interior, said pump housing having a exterior face and an interior face, said pump housing face interior face having a couple member, said couple member adapted to couple to said mounting member positioned on said mounting plate to thereby attach said pump housing to said mounting plate,   whereby when said mounting plate is mounted to sad motor housing face, and said pump housing coupled to said mounting face, said driven magnet and said driving magnet are magnetically coupled.   
     
     
         2 . The combination of  claim 1  where said mounting plate interior face has at least two projection standoffs, said standoffs sized so that said standoffs touch said mounting face of said motor housing when said motor is mounted to said mounting plate through said basin. 
     
     
         3 . The combination of  claim 2  wherein said mounting plate has a periphery, and said standoffs are located on said periphery and forming a space between said standoffs, said driving magnet being positioned in said space when said motor is mounted to said mounting plate through said basin.
