PUMP ASSEMBLY

Follow the procedure below and refer to the drawings in Appendix 6.
Part A: Pump Cartridge Assembly
A Pump Cartridge is a complete mag-drive pump less the outer
magnet and pedestal (see photo at right). A cartridge replacement is
a convenient way to quickly replace a pump that requires maintenance.
Pump cartridges are available from the factory and are designated by
placing a C in front of the pump model code.
Example:
Pump Model Code:
Cartridge Model Code: CH5FS6PEE100000US
1
Place the front housing (8) and rear housing (2)
on a flat surface with the bearing bores facing up.
Install the 1/8" NPT plug (9) into the front housing.
NOTE: Teflon tape should be applied to the threads
of the drain plug to prevent leakage.
NOTE: Standard housings (i.e., not containing bearing
flush grooves) are shown at right. Pumps ordered
with the Internal Bearing Flush (IBF) option will have
modified front and rear housings (see box below).

Internal Bearing Flush Option

Pumps ordered with the Internal Bearing Flush
(IBF) option will have modified front and rear
housings, as shown at right. The purpose of
the IBF option is to more effectively lubrcate
and cool the bearings when pumping ex-
tremely thin or extremely thick liquids. When
assembling the pump, the IBF grooves must
be oriented on the higher pressure discharge
side of the pump.
