Disassembly and Assembly of Pump
Caution!
Since the magnets used in the pump are powerful, be careful not to catch your fingers or hand
between them during disassembly or assembly. Also, keep the magnet unit away from any
electronic device (or ATM card with a magnetic strip) that could be affected by a strong magnetic
field.
Prior to servicing, the suction and discharge valves must be closed. The piping and the pump often
retain some liquid. It is recommended the piping and pump cavity be drained prior to servicing.
If dangerous liquid is used, wear protection and flush pump with clean water or decontaminant
prior to service.
Make sure power to the motor is off.

Disassembly
1. Loosen and remove front casing bolts (14) and (15).
2. Remove front casing (1). Wash and clean pump inside.
3. Remove impeller (2) and magnet capsule (4) from
rear casing (7). Magnet capsule should be kept free
of all metal chips. Store in a clean area.
4. Insert a screwdriver into the clearance between the
surface of motor bracket (11) and rear casing. Pull
rear casing forward while slightly lifting the screw-
driver.
Note! Take care not to damage the sealfaces. Do
not remove rear casing assembly unless necessary.
Spindle of all models "-D" and "E" cannot be re-
moved.
5. Flush and clean bearing (6) inserted into magnet
capsule as residue in the groove of bearing causes
insufficient lubrication and cooling.
6. For removing drive magnet assembly (10), stand
motor with motor bracket (1) on end (vertically).
Loosen 2 set screws with a socket screw key, acces-
sible thru the hole located at the bottom of motor
bracket.
