SELECTION NOTES

What to confirm for QDX/QX A Series

Provide water quality, lowest operating level, flow at total discharge head and cable arrangement. Use the full A-series suffix, electrical version and manufacturer curve. The published example QDX6-10-0.37A is rated 6 m³/h at 10 m with 0.37 kW and 220 V; it does not define every QDX pump. Ask for the selected configuration and minimum liquid level before ordering. Do not substitute a WQ sewage table for this clear-water family.

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