Just got this as a replacement pump for the first Graf pump I installed two years ago. The first one did fail, but not catastrophically. It just developed a leak from the weep hole that worsened over time. FCP Euro lifetime warranty covered the replacement. Even though the first one failed, I got the same brand as replacement because I still think the metal impeller is better than plastic. The impeller still looked like new after two years in service. Hoping for better luck with the seals/bearings in the replacement.

Better than the plastic OEM unit, also better than the cast impeler, since it's lighter

cheap but good upgrade from the old pump that came with my swap engine

Specially wanted metal impeller, installed no issues, 3K miles so far & no leaks. Good price for comparable pumps.

Great pump, easy install, great price, and metal impeller blades.

Not the original maker of water pumps for BMW, but its been in my E46 for several thousand miles with no problems. I also like the metal impeller over the plastic one on the factory unit. Cant beat the lifetime warranty either.

Fits like a glove, no leaks, and if it did leak you can't beat the lifetime warranty.

Graf water pump works as expected, easy install, dependable service after 1 year

Appears well built and is half the price of the BWM branded pump. If replacing in an E85 Z4, unbolt DS engine mount and jack up the engine a bit to get the old pump past the crash guard. Also, if changing thermostat at the same time, the smaller thermostat bolts can be used to push the old pump out by threading into holes on sides of pump.

better then OEM ... great packaging.. no leaking would use again.. great price.
