SELECTION NOTES

What to confirm for WQ Large Sewage Series

State particle and fiber characteristics, liquid density, flow at total head, lowest operating level, immersion and discharge layout. Obtain the selected pump’s solids-passage figure and installation drawing. One published example, WQ100-25-11, is rated 100 m³/h at 25 m with 11 kW at 380 V. Family maxima and different WQ suffixes are not interchangeable duty points. Confirm lifting, cable, control and guide-rail scope separately.

Published limits may describe different configurations within a series. Confirm that the required operating conditions are valid together.
