Source conflicts and installation checks
The manufacturer graph and technical table disagree on parts of the performance envelope. The chart below reproduces approximate graph readings; the separate rated and maximum values retain the published numerical table without blending the two. Neither is independently confirmed. Request a selection against the actual duty and supplied version before ordering. Maximum flow and maximum head are separate limits, not one duty point. The dimension table prints D=40 mm although nominal discharge is 50 mm (2 inch); confirm the actual flange/elbow interface and do not fabricate from nominal size alone.
No zero-head endpoint or extrapolated performance has been invented. Confirm cable, voltage, phase, operating immersion, duty point, elbow/flange and installation clearances before purchase. The grinding system does not establish a verified solids-passage diameter.
