Water pump GRAF or OEM Volkswagen

Further, the metal unit (Graf) had a sort of reptile-skin texture to the impeller fins, no doubt a product of the casting process. I spent some time with a dremel polishing the fins (because that's how I roll ) to get them as smooth as the plastic ones being replaced.

I went with the Graf in my 95 passat glx. The graf has a cast iron impeller wheel. The stock one that was in there was plastic and some fins broke off when the pump failed

my water pump went at 80K (KM)'s (got it towed to georgetown VW) and when i got my OEM replacement it was metal... compared to the plastic one they took out... Saw it touched it... (they showed me the old plastic one) i thought it was weird and they said in 2002 and after they have metal water pumps... before that it was "plastic"? anyways its in and i have a metal one... and i got it from a VW dealer... OEM part...

My OEM plastic one broke and so did the metal-impeller Graf I replaced it with. They Graf seized up and leaked whereas the OEM plastic one just leaked.
