LSWm300(A) hydraulic performance
This individual reference curve uses approximate graph readings from the orange curve explicitly labelled for LSWm300A in the locally published LEO 50 Hz sheet. Values are rounded to 0.1 m head, with graph-reading uncertainty of approximately ±0.25 m; they are not published numerical test points. Only the sampled portion of the original curve is shown, with no extrapolation.
Source discrepancy: the manufacturer’s plotted head/flow coverage does not fully coincide with its tabular maximum head and maximum flow. The original plot is included for comparison; its values have not been rescaled or extended to force agreement with the table. Tabular maxima below remain separate limits, not a simultaneous duty point. Confirm the applicable supplied version and duty with Krächtig before ordering.
