Frequently Asked Questions

What is an axial flow pump and how does it differ from centrifugal pumps?
An axial flow pump moves water by creating pressure through propeller-like impellers, pushing water axially along the pump shaft. It is designed for high flow rates at low heads, unlike centrifugal pumps which are better for higher heads.
What are the main applications for this QZ submersible axial flow pump?
The QZ series is primarily used for agricultural irrigation and drainage, flood control, urban water supply, shipyard water level control, and various水利工程 projects requiring large-volume water movement.
What does "dry-type motor" mean for this submersible pump?
Dry-type motor means the motor is sealed and protected from water ingress but operates in a dry environment within the submersible housing, ensuring reliable performance and easier maintenance compared to wet-wound motors.
What installation options are available for this large submersible pump?
The QZ series offers multiple installation options including vertical fixed, inclined, portable, and rail-mounted configurations to accommodate different site conditions and project requirements.
What is the maximum flow rate this flood control pump can handle?
The QZ series can handle massive flows up to 26,000 m³/h, making it suitable for major防洪 projects and large-scale irrigation systems.
What materials are available for this agricultural drainage pump?
The pump body and impeller are available in cast iron, stainless steel, bronze, or carbon steel, with shafts manufactured from 304 or 316 stainless steel for durability in various water conditions.
Can this pump handle slightly polluted water?
Yes, the QZ series can handle clean water and slightly polluted water typical in agricultural drainage, flood control, and municipal applications. For highly abrasive or corrosive media, please consult our engineers.
What certifications do your ISO certified pumps hold?
Our pumps are manufactured in ISO 9001 certified facilities. We also maintain ISO 14001 environmental management and ISO 45001 occupational health and safety certifications.
Do you offer OEM service for this submersible axial flow pump?
Yes, we offer OEM and ODM services. We can customize materials, motor specifications, installation configurations, and impeller designs to meet your specific project requirements.
What is the typical lead time for large QZ series pumps?
For standard configurations, lead time is typically 30-45 working days. Large custom pumps may require additional time. Please contact us with your specific requirements for detailed scheduling.
