Open the builder and pick this listing from the catalog picker — the solver runs it with the catalog's own figures, at your design point or across a year of weather.
| 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.
