Mike Sheppard, Scott Secor and Mr. Holohan helped me the last time I needed help with B & G. Here's another one. This pump is 65 years old and has died. The pump flanges are 8-1/2" apart, so it's not a Series 100 model. Must be a PR (high volume) or HV (high head) series, no? It serves an 8-loop manifold, 1/2" copper loops; no idea what the loop lengths are.
We figured out last time the the dead guy who did the installation probably oversized the pump and I think the same is true for here. A series 100, Taco 007 or a Grundfos 15-55 will probably do the trick.
Any comments?

This was on State Supply's site showing a replacement bearing:
"Bell & Gossett front bearing for B&G model 189101, 189102, 189103,189129, and 189163 bearing assemblies on series HV, 1, 1-1/2, and 2 pumps."
So that's probably an HV.All Steamed Up, Inc.

The size and shape of the impeller is a good rule of thumb for determining a circulator type, narrow, large diameter impellers are typically high head, as a 3450 rpm motors.
Did those older 3 piece circulators ever use 3450 rpm motors, seems 1/6 hp 1750 is most common?Bob "hot rod" Rohr

These are higher flow lower head than Grundfos. We stock all the parts for our service work for them still. Bearing assemblies, motors, motor mounts, couplers. Great old pumps. they are 1725 rpm.0

My guess is could be the 1-1/2" also which is the hv on chart. I run into a lot of the hv and the 2" 1/6hp.

all right Dan, without a good look at the volute and of course the impeller, what was the clue to say PR not HV?
