Product Overview

100mm is where the range shifts from factory-scale to municipal-scale. Five models cover the common combinations of flow and head found at this size, plus one grinder version built for heavier organic loads.

Model	Flow (m³/h)	Head (m)	Power (kW)	Notes
WQ-100-80-10	80	10	4	Low-head, tank transfer
WQ-100-80-20	80	20	7.5	Same flow, more lift
QW-100-100-15	100	15	7.5	Common municipal spec point
WQ-100-100-25	100	25	11	High-head
WQ-G-100-100-15	100	15	7.5	Grinder, seafood/slaughter-house scale

If this size is going into an international tender, custom motor voltage and frequency are available, but the final performance curve document is only issued after the motor spec is locked in — so plan the documentation timeline around it rather than expecting a same-day turnaround.
