Water pump Saleri or Pierburg

Pierburg. It’s literally exactly the same just no BMW logo.

Pierburg is the OEM maker of the BMW water pump. Spending the extra for the BMW is ridiculous when they are 100% the same exact same pump from the same company from the same factory.

I'm working on adapting these water pumps to a variety of older engines. This one will be going on a Chevy LSx. The pumps support two different control schemes; one via PWM (no feedback) and one via LIN. I will be working on reversing the LIN communications and building a more sophisticated controller soon.

PIERBURG makes a good water pump...

Water pump on the T4 EVWK went ok. But, it is a Saleri pump from Italy.

It happens. I’ve had maybe 3-4 do this out of probably 300 we’ve changed at the shop. Once was a pierburg but the rest were autozone duralast etc.

After researching I decided upon a Saleri pump from World Impex since it has the resin impeller and is 1/4 the cost of OEM. Well, the first one arrived with one of the vanes broken off the impeller. Impex rma'd it, but the second one arrived in even worse shape with a big chunk broken off the impeller. I attribute it to poor packaging.
