Product Description
The vertical axial flow pump is a type of pump that conveys liquid by generating axial thrust through impeller rotation. When the impeller rotates at high speed, the blades produce lift on the liquid, causing water flow along the pump shaft direction, achieving large flow at low head. The centrifugal axial flow pump features simple structure, easy operation and maintenance, convenient installation, and long service life. Widely used for stormwater and wastewater pumping in municipal and industrial applications, such as flood and rainwater control, large-flow drainage and irrigation, raw water intake, liquid transfer in wastewater treatment plants, water parks, fish farming, and other large-scale water circulation. Extensively applied in irrigation, water supply and drainage, inland waterway dredging, power engineering, and other fields requiring large flow but not high head. This is an efficient mechanical seal axial flow pump.
Product Features
Impeller Structural Design: Impeller with curved blade structure fully utilizes its function, effectively preventing various tangling and jamming.
Small Footprint: Offers large flow; compared to other high-flow pumps, this centrifugal axial flow pump has simpler structure, lighter weight, smaller dimensions, and tubular shape minimizes floor space.
Easy Operation: For vertical axial flow pump, the impeller is fully submerged during operation, requiring no priming upon start, making operation simple and convenient. For adjustable models, changing the blade angle maintains efficiency when conditions vary.
High Efficiency and Energy Saving: Hydraulic model designed using three-dimensional flow theory and CFD simulation, achieving theoretical optimum performance. Hydraulic components precision cast using metal molds, faithfully reproducing flow passages, ensuring efficiency of mechanical seal axial flow pump with a wide high-efficiency range.
High Reliability: Intake flow passage designed rationally for vortex-free inflow and stable operation. Absolute concentricity of pump shaft and excellent static balance of rotor components ensure low vibration and noise at high speeds.

FAQ
Q: What is the most characteristic feature of an axial flow pump? What applications is it suitable for?
A: The most characteristic feature is "large flow, low head." It can handle very large flow rates but provides relatively low head. Suitable for applications requiring moving large volumes of liquid without significant lifting height, such as large-scale farmland irrigation, urban flood control and drainage, power plant cooling water, dock drainage, aquaculture water circulation, large water features, etc. The vertical axial flow pump is an ideal choice for these fields.
Q: What are the requirements for the inflow condition when installing an axial flow pump?
A: It requires uniform, steady inflow, avoiding vortices and pre-swirl as much as possible. Improper inflow conditions (e.g., biased flow, vortices) can reduce pump efficiency, increase vibration, and cause cavitation. Therefore, a well-designed intake sump or inflow channel is necessary to ensure smooth, symmetrical flow into the pump. This is crucial for the performance of centrifugal axial flow pump.
Q: What is the purpose of the "adjustable blade" function in axial flow pumps?
A: For adjustable axial flow pumps, the pump performance (flow and head) can be regulated by changing the blade setting angle. When actual operating conditions (e.g., water level, flow demand) change, adjusting the blade angle allows the pump to always operate within its high-efficiency zone, achieving energy savings and adaptation to changing conditions. This flexibility is an advantage of advanced mechanical seal axial flow pump.
