How the model reads against this maker's data

Grundfos TP in-line pumps read from the data booklet's curves	214 listings	the shaft power at every listing's rating point sits under its rated motor and the end of the curve reaches at most 1.04 × it; the implied pump efficiency runs 0.29 on the smallest sizes to 0.80 on the largest, the shape a fixed-speed in-line range has; electrical power through the maker's printed motor efficiency, no IEC class assumed
Circulator curves read from vendor charts	12 listings	curve tops within 3.5 % of each Grundfos page's P1 table; every Wilo listing under its datasheet's P1(max)

From the validation page; every row is held by a test.

Listed from published data; a listing's figures are the manufacturer's, the model that runs them is ours. Solver results never depend on who has claimed what.
