NSPECTION
Inspect all elastomers when performing pump maintenance. We recommend replacing elastomers (o-
rings and gaskets) during seal, pump shaft and/or motor replacement. If the impeller nut gasket fails,
the threaded hole on the impeller nut and the threads on the end of the shaft will need to be cleaned. A
wire brush is recommended for cleaning these threads.
