Perhaps someone could enplane what the difference is between a Rebuilt Pump and a New Pump other then " the price "
Same casting
Same Bearing ( excluding the China Crap )
Same Seal
Same Impeller

As you seem very incapable of understanding some of the basic facts I will try again to enlighten you.
New pump from GPM in Germany has a German made seal cartridge. GPM does not rebuild pumps so rebuilt pumps are rebuilt by a totally different company and they use a different seal cartridge - cheaper and low quality - We sent a number of pumps to GB and he dissected them all - reported on Rennlist - search is your friend.
Every time a WP is rebuilt the fits are compromised. Hence the seal cartridge moving in the casting. Hence the metal impeller's coming off the shaft.
I know of at least 6 different casting used for 928 water pumps - some are good quality and some are not - its a crap shoot what you will get.
Every time someone sends back a core - it could be a cheap Chinese knock off core -so the one you are getting could be really bad.
You asked for advice and then totally disagreed with everything you were told. Why the F**ck did you ask for advice in the first place is beyond my comprehension.
All Porsche parts come from three main warehouses here in the States - Atlanta, Ontario and the North East. The three warehouses are fed from the main warehouse in Stuttgart. Porsche does not make parts their suppliers do.
I only do about $1m of parts business with Porsche so what would I know about how the system works.
All Porsche parts have a warranty of 2 years/24k miles. That warranty is usually only honored providing the parts are fitted by a Porsche dealer. Even if they do honor the warranty they will only replace the part or give you your money back. So $188 will go a long way to replacing the engine in a 928 because of a seized water pump!!!!!!!!!!!!!!!!!!!!
Now that you have advised everyone to use a cheap rebuild I am sure you will cover the cost of engine rebuilding if and when their pump fails 8>(.
I have to believe that most 928 owners are little bit more savvy than you appear to be.
