Manufacturer-tabulated points from the standard EDH section are reproduced for this model. EDH and EDH-F rows are kept separate where their figures differ. Values outside this table are not extrapolated; the final listed flow is not a stated maximum flow.
Individual hydraulic curve and dimensional drawing
This figure is for the standard EDHm20-20, using the manufacturer row on printed page 82: overall length L 626 mm and height H 248 mm. It is not the EDHm20-20-F variant. The plotted points match the hydraulic table below; no shut-off head, maximum flow or extrapolation is inferred. Confirm the supplied assembly and duty point.
