8.2.1 Casing wear ring and impeller wear ring inspection and replacement
Casing and impeller wear rings should be replaced when they are badly grooved and/or when the
pump’s performance does not meet the system’s requirements.
Whenever it is necessary to replace either ring due to wear, both rings must be replaced.
8.3 REASSEMBLY
Observe the plant's safety precautions when lifting heavy components. Request
help when moving or positioning them.
Mounting of bearings should be carried out in a dry, dust free area away from
metal working or other machines producing shavings and dust to avoid
contamination of bearings.
The bearings should remain in their original packaging. Once they are to be
assembled in the shaft, they must be removed from their packaging, and the
preservative in the outside diameter and the bore must be wiped out.
Bearings should be demagnetized before mounting them, to avoid contamination.
During assembly, all threads must be protected with an anti-seize agent.
Lubricate with grease or oil the inner diameter of the sleeve and the outer
diameter of the shaft for installation.
