Inner Magnet Installation Diagrams
Three kinds of inner magnets can be used in the pumps, as shown below. The axial positioning of the inner
magnet is automatically set by snap (retaining) rings installed on the drive shaft. The snap rings and key serve
to lock the inner magnet on the shaft.
I. MCS, MCB & MCV Inner Magnets:
The rounded edge of the inner magnet
must face the front housing.
II. MCU Inner Magnet:
The hub of the inner magnet
must face away from the front housing.
III. MCA & MCC Inner Magnets:
The counter - bore of the inner magnet
must face the front housing.
NOTE: These inner magnets require longer
drive shafts than those of the other
magnets shown above.
