10.2.4 Impeller Break-Loose Device
WARNING
1 Impeller
2 Break-Loose Device
Energy can be released during disassembly of the tightened
Impeller. Break loose devices, lifting devices and Impeller release
rings could spring suddenly and injure nearby personnel.

Rotate the impeller until the tip of one blade is facing the pump discharge.

Insert the break loose device through the eye of the impeller and attach
to trailing edge of blade facing discharge.

Rotate the shaft in the direction opposite to normal, using the pump pulley
or a spanner wrench.

For ease of impeller removal, the shaft threads should be heavily coated
with anti-seize compound during re-assembly. Two aramid paper gaskets
should be used between the shaft sleeve and the impeller.
10.2.5 Impeller Removal with Impeller Lifting Device
WARNING
Impeller Removal with Impeller Lifting
Device
Do not remove, lift, move or reinstall Impeller without properly using
a recommended Impeller lifting jig.

For impeller removal or installation, grasp the impeller at the suction eye.
The impeller can be leveled by turning the adjusting bolt which bears
against the impeller nose. This is especially useful during re-installation.

For impeller removal ensure that the lifting line is tight prior to thread
disengagement.
10.2.6 Casing Removal
It is recommended that at least two lift points be used when moving any pump casing. This permits greater safety and control of
the component. Where applicable, GIW pump casings are supplied with cast lifting eyes for this purpose. Note that if the chain
hook does not fit the lifting eye, an appropriate clevis should be installed. Another acceptable lifting point is a chain secured
around the discharge flange, being careful not to damage the bolt flanges.
10.3 Wet End Assembly
WARNING
Refer to Section 2.9 "Assembly & Disassembly Safety" prior to working on the pump.
