Individual hydraulic curve and dimensional drawing
This figure uses the published standard EDH row for EDH20-30, 3-phase (manufacturer printed page 82). Dimension symbols follow the manufacturer outline, which is not to scale. Straight interpolation only; no inferred shut-off head, maximum flow or extrapolation. Confirm the supplied assembly and required duty point.
