I’ll look into this a bit and would assume it does not meet boiler flow requirements otherwise why the hell isnt this the one they supply...
This might not apply to this deal, but I'm seeing lots of mismatched packages due to COVID and supply chain problems. The suppliers can't get the correct parts so they substitute and probably figure the customer won't complain if they over-spec the substitute - in your case a 3" substitute for a 2.5" pump.
Forgive me my nonsense, as I also forgive the nonsense of those that think they talk sense. Robert Frost
