I've had good luck with GMB pumps previously. I used Gates also, but I couldn't find any. They might not be manufacturing them any longer. |
Short vane impeller , the all 3 GMB pumps use the same impeller & no difference between the cast iron housing & the 2 aluminum ones they offer / the standard alum. 1 is identical to the HP alum. 1 they sell.
