Source qualifications and installation checks
The individual hydraulic reference reproduces the exact numerical manufacturer row at 50 Hz. Straight line segments only connect printed points; they are not measured intermediate points or a certified acceptance curve. No zero-head endpoint, best-efficiency point or operating range has been invented. Maximum head occurs at Q=0 and is not a continuous-duty recommendation. Liquid-temperature sources differ: the model sheets print +5 to +60°C while the full commercial catalogue prints +5 to +75°C. Confirm the supplied pump/seal limit; this page does not promise operation above +60°C. A–F, K and L are millimetres. G/H are source connection designations in inches, not millimetres. Confirm the supplied thread standard and orientation. This model’s dimension row is blank in the shorter European model sheet. The values here come from the complete LEO commercial catalogue, printed page 58, not from stage-count extrapolation or packaging.
