Section 14: Pump Disassembly Procedure - 6300, 7200 & 8200 Pumps
Refer to Figure 7.
Although some minor disassembly is possible with the complete pump/motor assembly still in
place, it is recommended that the pump/motor unit be disconnected and moved to a maintenance
area.

WARNING
Residual pumped fluid will be present in the pump. Follow all precautions outlined in the Material
Safety Data Sheet (MSDS) applicable to the liquid being pumped to ensure safe handling.
1. Remove piping from the ports.
2. Mark cover, housing and bracket before disassembly to ensure proper reassembly.
3. Remove the cover screws, cover, housing and idler.
4. Inspect the following parts carefully for deep grooves, scratches or other damage:
•
The I.D. of the housing.
•
The end face of the rotor.
•
The O.D. of the rotor.
•
The O.D. of the idler.
•
The I.D. of the idler.
•
Both faces of the idler.
•
The O.D. of the idler pin.
•
The inside surfaces of the cover including the crescent.
5. Check for signs of wear. A decrease in capacity is generally caused by the abrasive action of
foreign materials in the liquid, resulting in excessive end clearances. End clearance can be
reduced by adjusting the thrust bearing. To adjust the end clearance, see assembly procedure.
!
CAUTION
The pump must be separated from the magnet coupling if further disassembly is required. Follow
the instructions below.
Use jack screws to disassemble models 6300, 7200 & 8200 Series pumps. Jack screw kits are
available as part number 2CMG 558 for models 6302-4, 7202-4 & 8202-4 and part number 5CMG
558 for models 6305-6, 7205-6 & 8205-6.
DO NOT PLACE HAND OR FINGERS BETWEEN THE HOUSING AND ADAPTER. The magnets
are extremely strong and will attract all metallic objects and can be the source of pinch points. Do
not wear watches or other metallic jewelry when working with magnets. See warning on Page 2.
Failure to follow proper procedures or use appropriate tools could result in injury to you or damage
to either personal property or the pump.
6. Remove the screws that attach the bearing housing / outer magnet sub-assembly to the
adapter.
