Ive got a berkeley pump and just got an ultimate wearing for it but the wear ring surface on this ultimate wear ring measures .975 as to where my bronze wear ring measures 1.075, Do I have the correct wear ring? Just checking before I go ahead and machine .100 off the front of my impeller. And if so just curious as to why it is .100 shorter.
Yes the ultimate wear ring falls .100 short of reaching the rear of the wear ring surface on the impeller. Its really not a big deal just not real excited about not being able to snatch it out and go back to a bronze wear ring without having to either recut the wearing surface on the impeller or shortening a bronze wear ring.
Yeah your right! Im not wittling on my impeller to make this thing work. Still thinking about what to do about it but right now Im thinking about making a .100 shim to put in behind this thing and machine the the shoulder back on the wear ring to make it work for now.
Every point where you can pick up a sealing surface the better the whole thing will seal in the end. Because when you have pressure in the bowl less water will get by a .010 gap versus a .100 gap makeing less water available to get by the radial surface and the front edge creating a better seal.
