Several holes on the impeller

Thread Content

It’s a 200 impeller; there are several holes on the back hub. I’m not sure what those holes are for, and I don’t see any rear ring either

A hub that big is just a mouth ring, isn’t it?

Fluid pressure balance hole, which reduces the axial force on the shaft and thus lowers the load on the bearings
