6.9.2 Reassembly of the pump when it is required to remove the rotating element

NOTE: All bearing, O-rings, lip-seals, mechanical seals, gaskets, impeller rings, and casing
rings should be replaced with new parts during assembly. All reusable parts should be
cleaned of all foreign matter before reassembling. The main casing joint gasket can be
made using the upper and lower half as a template. Lay the gasket material on the casing
joint. Trim the gasket by lightly tapping with a peen hammer so it is flush with the inside
edges of the casing (do not hit casing edge with hammer hard enough to round edge.
NOTE: Precut-casing gaskets can be ordered to minimize the amount of trimming.
