Three submersible axial flow pumps for industrial drainage

Submersible Mixed Flow Pump

The submersible mixed flow pump from the QH series are single-stage centrifugal pumps that have a submersible motor and are equipped with an mixed flow impeller. The pump itself is a high-flow submersible pump suitable for pumping large quantities of water at low heads. The pump can reach an impressive flow rate of up to 20,000 m3/h.

Features

High Efficiency & Large Flow Capacity
Optimized impeller design combines axial and radial flow principles, delivering high flow rates with moderate head pressure.
Ideal for applications requiring massive water transfer with minimal energy consumption.

Compact & Space-Saving Design
Fully submersible structure eliminates the need for separate pump houses or complex installations.
Perfect for confined spaces such as wells, tanks, or underground sumps.

Robust & Corrosion-Resistant Construction
Engineered with stainless steel, cast iron, or anti-abrasive materials for longevity in harsh environments (e.g., seawater, wastewater, industrial fluids).
Sealed motor protection (IP68) ensures reliable operation even under continuous submersion.

Low Maintenance & Easy Operation
No priming required—submersion enables instant startup.
Minimal moving parts reduce wear and simplify servicing.

Versatile Performance Range
Adaptable to varying water levels and dynamic conditions without cavitation risks.
Customizable configurations (e.g., discharge orientation, power options) for specific projects.

Environmentally Friendly
Quiet operation with low vibration, suitable for eco-sensitive areas.
Energy-efficient motors comply with international standards (e.g., IE3/IE4).
