"Water Pumps" plastic, metal or composite Impellers?

I'm sonsidering replacing the water pump on my 01 325Ci but can't decide on which to buy. It seams several are offered and thought, well best way to find out about these is to ask you guys. Has any one had good or bad experience with either?

Original BMW WP is my preference. What do you mean by "plastic...or composite"?

Your existing (likely OE) water pump is composite.
Saleri was the OE water pump supplier for E46s, and you can find them for about $60 shipped.
Cheap, what was OE, and performs flawlessly.

Be glad your choices are so cheap. E90 pumps are a few hundred bucks!

They're also fairly advanced with their electrically-driven motor The reason why it is that way is so that the turbos can cool down after the car is shut off, because they know that no typical buyer is going to actually let their car idle for a minute before shutting it off. The pump will continue running even after the car is shut down to cool off the rest of it.

most suggest the Saleri brand. I had good results with GEBA and its still working in previous car afaik. but since the Saleri is so close in price, and brand bmw uses just go Saleri.

if you plan to keep your car and add another 180,000 miles you could consider Stewart pump. but for anything less the cost is not worth it.
