I have two single-speed brass Grundfos circulators but need one more. I'm looking for one like, or similar to the one pictured below.
Thanks,
Jack

Thanks,

I believe that you may need to substitute a stainless steel model for an open system.They are more common.
Update. there is a replacement available @JackW
try this

The pump curve is close enough for government work.

@hot_rod, I've been watching eBay, but nothing yet; I even checked FB Marketplace. I don't know what union body DHW pumps are. I doubt I'll find the exact model pump; how close to the specs of the ones I have now do I need to adhere to? What do I need to look for on the nameplates?0

I've got one of those brass Grundfos circs on hand with 1/2" sweat connections (pretty sure it's a 15-42, will have to double check), brand new if you'd be interested0

@JackW It could certainly be reduced to fit, the performace curve is almost identical as shown above. I looked this morning, they are actually 15-18B5 models. New on SupplyHouse they're $265 plus tax or $297 for the 3/4" version (B7), I'd sell you one of these for $200 shipped if you wanted.0
