Recommended inspection to be performed at any service interval:
Impeller - Inspect for cracks or tears. Also, inspect for excessive abrasion of vane ends, pitting, and a bowed set. Replace annually, or if any of the conditions exist.
Wear Plate - Inspect for wear, flatness, and pin for fatigue. Replace at major (minor and
major for 17000 series) pump rebuild or if wear is evident to maintain pump flow and suction performance.
Cam - Replace at major pump rebuild or if pitting/wear is evident.
Cover - Replace at major pump rebuild or if wear exists to maintainpump flow and suction performance.
Mechanical Seal - Replace at minor and major pump rebuild or if leaking.
Lip Seal - Replace at major (minor and major for 17000 and G series) pump rebuild or if leaking.
Shaft - Inspect for wear in area of lip seal and rubber impeller. Grooving of lip seal area or heavy fretting of the impeller end shaft will require shaft replacement.
Bearing - Inspect for loss of grease, corrosion or rough rotation. Replace at major pump rebuild or if these conditions exsist.
View the appropriate OIPM or Marine Catalog for assembly, disassembly, and recommended Maintenance Schedule. The recommended Maintenance Schedule can be found on page 39 of the Marine Catalog.

A more detailed walk-through of disassembly and re-assembly for a major overhaul would something many of us could use. Perhaps some photos and some details on the tools required.
ReplyDeleteCan you replate the wear plate with a stainless steal wear plate ?
ReplyDeleteSchotman,
ReplyDeleteWe do have OIPMs which give some instruction on how to repair our pumps. If you need information beyond that I can certainly help - obviously I do not check this blog often enough, but you can certainly call me at 651-766-6358 (direct line) or e-mail me at matt.cottrell@pentair.com.
Scott,
ReplyDeleteWhat wear plate are you referring to? We have several stainless steel as well as brass wear plates.
