Default Re: Water pump core differences

The old steel shafts were MUCH harder than the stainless crap we get these days. I understand why the vendors sell the stainless ones - people like the look of a clean shaft and are not concerned about how long it will last. I drive my cars so I need something more durable. To get this with a stainless shaft, I figured I should have nothing rubbing on it like the bearing bush or gland packing. I put a sealed ball bearing front and back and a ceramic seal. I can't see why such a pump won't outlast me and the next owner.
