water pumps

[Ed Kellock]

I have two new ones, a Graf made in Italy and a Hepu made in Germany.
Which one is better?

The Hepu impeller is gold in color and I'm not sure if that's plated or
actually brass or something.

The Graf has 5 3mm holes in the impeller in between the blades.

The one I'm taking off the car has no holes, does not appear to be or have
been gold in color.

The old one also has a different belt pulley treatment with a shoulder
around the edge to keep the belt center on the pulley.  Neither new pump
has that at all.

Both boxes the new ones came in have the same p/n printed on them.

Thanks,
Ed
