Taco ECM circulators

have you contacted TECO support?

There is nothing easier than calling the manufacturer.

A list of specs use AI to create it like @Robert_25 did for you. I would urge you however to look at the more important specs that are not so easy to put in a side by side comparison and that is the pump curve. What I have done when I needed a physical copy to quickly look at is print the various pump curves for common pumps I deal with. If you know your systems requirements (which you must know to properly spec out a pump..) using the various manufacturers pump selection tools is typically easier than using the old field books they hand out, though I do think both are nice to have. I have been specifying pumps for over a decade and never found a need for a list of pumps and specs, it's not relevant imo. Pump curve trumps it all, your available voltage on site tells you which voltage pump to go with, and if you can't find one that meets your requirements with the correct volute length then you will need to re-pipe
