QSZ Submersible Axial Flow Pump

A QSZ vertical axial flow pump is a high-volume, low-head, submersible pump designed for applications like drainage, flood control, and irrigation, often featuring large, angle-adjustable impellers for broad flow ranges. It works by pushing water along the same direction as the pump shaft, providing stable, energy-saving operation for large quantities of water, and is available in various configurations including floating, well-hanging, and pool-hanging installations. 

The QSZ vertical submersible axial flow pump is connected with the motor and works in the water at the same time. It can be operated remotely or controlled automatically. No pump house (pump station) can be built, and no ground building facilities are required, thus greatly saving the investment of station construction.The machine also has the advantages of simple structure, convenient installation, use and maintenance, and the electric motor adopts water-filled structure, which ensures the safety and reliability of the electric pump during operation, and also has the advantages of high efficiency of the pump station device.

Features

High flow, low head:

These pumps are optimized for moving large volumes of water with relatively low pressure. 

Angle-adjustable impeller:

The blades can be adjusted to suit specific customer needs, allowing for a wider range of flow rates and performance. 

Submersible design:

The pump and motor are combined in a coaxial design, reducing shaft loss and increasing durability. 

Robust materials:

Often made from cast iron or stainless steel, designed for reliability in various water conditions. 

Integrated safety features:

Many models include leakage and temperature detection devices to prevent motor damage from overheating or leaks. 

Versatile installation:

They can be installed in various ways, including wellbore hanging, pool hanging, or fixed on a pontoon. Significantly reducing civil construction costs compared to traditional dry-installed pumps.

Ease of Maintenance:

Equipped with guide rails and lifting chains for quick retrieval without entering the wet well.

Typical Applications

Urban stormwater drainage and flood control

River and lake water circulation

Agricultural irrigation and drainage

Industrial water supply and cooling systems

Wastewater treatment plant intake pumping

Advantages over Traditional Axial Flow Pumps (e.g., QZ)

Reduced civil engineering requirements (no large pump house or separate motor room);

Lower noise and vibration at ground level;

Simpler installation and alignment;

Suitable for automated/remote operation.

The QSZ vertical axial flow pumps represent a modern, integrated approach to axial flow pumping, increasingly favored in municipal, environmental, and industrial projects due to their space-saving design and operational efficiency.
