Technical sheet

Model ST-0510

Performance curve

A pump has a performance curve rather than a single flow and head. Qmax and Hmax are at opposite ends and never occur together: at maximum head, flow is zero; at maximum flow, head is zero. Actual operation lies between these extremes.

Maximum head: 67m
Maximum flow: 1.5t/h
Midpoint: 46m

Chart 1. Head (m) against flow (t/h, l/min), ST-0510. Blue points show the manufacturer's measured values. Move the pointer near the curve, or touch it on a phone, to read the head and flow at any point.
