Denor QSZ Submersible Axial Flow Pump – Space-Saving, High-Volume Water Transfer Solution
The Denor QSZ Vertical Submersible Axial Flow Pump is a high-performance pump engineered for moving massive volumes of water against low to medium heads. Unlike traditional dry-installed pumps, the QSZ axial flow pump features a fully submersible, integrated motor-pump design that eliminates the need for a separate pump house, significantly reducing civil construction costs.
The QSZ Axial Flow Pump is widely used in municipal drainage, agricultural irrigation, and industrial water circulation, offering flexible installation options including fixed, floating, or pool-hanging configurations.
Advantages & Design Features
1. No Pump House Required:
The submersible design eliminates the need for dry pit construction, saving up to 30-50% on civil engineering costs compared to traditional axial flow pumps.
2. Angle-adjustable impeller:
The blades can be adjusted to suit specific customer needs, allowing for a wider range of flow rates and performance.
3. High Efficiency & Energy Saving:
The coaxial motor-pump design minimizes transmission losses. Combined with hydraulic optimization, it ensures stable, low-vibration operation with reduced energy consumption.
4. Integrated Safety Features:
Built-in leakage sensors and temperature detectors continuously monitor motor status, preventing damage from overheating or seal failure for worry-free operation.
5. Easy Installation & Maintenance:
Equipped with guide rails and lifting chains for quick retrieval without entering the wet well.
6. Versatile Installation Options:
They can be installed in various ways, including wellbore hanging, pool hanging, or fixed on a pontoon.
7. Robust Material Construction:
Available in high-grade cast iron or stainless steel, designed for reliability in various water conditions.

Municipal Engineering
Vertical axial pumps are the core part of municipal water supply and drainage system due to their features of large flow rate and less maintenance requirements.
Agricultural Irrigation
Ideal for lifting water from rivers, canals, or reservoirs to irrigate large farmlands, as it can handle the high flow rates required.
Flood Control and Drainage
Widely used in pumping stations to quickly move massive amounts of water from flooded areas (cities, agricultural fields) to rivers or seas.
Industrial Circulation
Commonly used in power plants, refineries, and large factories to circulate cooling water through condensers and cooling systems.
Water Transfer Projects
Essential in large-scale aqueducts or cross-basin water transfer schemes where water needs to be lifted only a short height but over massive volumes.
Shipbuilding Drainage
The vertical axial flow pumps serve as the dry dock pumps in shipbuilding plants to evacuate the large a mount of water from the dock during the manufacturing and repairing process of ships.
