ZQ submersible axial-flow pump

The Kaiquan ZQ and HQ series blade‑type semi‑adjustable submersible axial‑flow and mixed‑flow pumps (collectively referred to as submersible electric pumps in this catalog) represent an upgraded generation of conventional axial‑flow and mixed‑flow pumps. They retain the key advantages of high single‑unit flow rates, a broad head range, and high efficiency. The pumps are driven by dry‑type, fully enclosed, submersible three‑phase induction motors. This series of submersible electric pumps can operate continuously while submerged for extended periods, offering performance benefits that traditional pump sets simply cannot match.
