Thanks for the followup.

These pump/motors are not bad units. The seals will leak eventually, but every rotating seal will do the same once the rpm-hrs are up. My pump runs 12hrs/day, 365 days per year for 4380 hrs/year service. I had seals last 5-7 yrs w/o leakage, thats over 20000 hrs service life. Many turbine engines won't do that many hrs w/o an overhaul.

Only thing I might change is to create some type of deflector device (rotating disc?) on the shaft between the end bearing and the pump. This would prevent water getting to the bearing and allow an easier repair. Still, it's not too tough to replace the bearing.

My main pump has a rear bearing noise that's been going on for about a year, and I've put off pulling the pump. The worst part for my pump removal/installation is releasing the wiring from the pump and unscrewing the conduit by rotating the pump. There isn't room for an interior conduit nut and the conduit threads into the pump shell. A real PIA.

I ***ume all your thru-body bolts released w/o problems? I'm hoping my remaining two come away easy when I replace the rear bearing.
