The one shot showing the impeller side. That's the smaller impeller. I have had reservations that maybe that smaller impeller is OK. As the thermostat is the major restriction to flow. But GM wouldn't have installed the larger impeller if they thought it wasn't needed. I'd pass on the GMB till Caradon starts building the H again. If you need a pump now. It's the best smaller impeller one due to the roller. Bob Dunahugh

In GMB's product specs it lists 6 impeller vanes, but in their picture
it shows 8 vanes... so hard to say what impeller they use.
