A vertical axial flow pump represents a large-scale vertical pumping system comprising inlet channel, impeller, guide vane and outlet channel, designed for high-volume, low-head liquid transportation, extensively utilized in agricultural irrigation/drainage, water conservancy projects, power plants, saltworks, chemical industries and related sectors.
The vertical axial flow pump constitutes a characteristic single-stage, guide vane pump featuring high efficiency, substantial flow capacity, minimal head requirements and excellent cavitation resistance. The vertically-mounted pump occupies minimal space, incorporates adjustable blades with variable performance parameters, and proves suitable for low-water-level conditions, resulting in exceptionally broad application scope.
Comprehensive premium material selection accommodates diverse media: stainless steel SS304, SS316, SS316L, 904L; duplex stainless steel CD4MCu, 2205, 2507; Alloy 20; Hastelloy; Titanium; Monel; Nickel...
Applications of Vertical Axial Flow Pumps:
Vertical axial flow pumps are ideal for high-flow, low-head applications.
Agricultural irrigation and drainage;
Power plant water supply and drainage;
Urban flood control;
Municipal water supply;
Port water supply and drainage;
Thermal power station circulating water transfer;
Harbor water level regulation;
Aquaculture operations;
Salt field water extraction;
Soda ash process salting-out and low-temperature crystallization;
Phosphoric acid production, seawater evaporation salt production, and other chemical processes.

Structure of the Vertical Axial Flow Pump:
Suction bell: Medium and small vertical axial flow pumps typically employ suction bells; large vertical axial flow pumps generally utilize elbow or bell-type suction channels to direct water into the impeller with minimal energy loss.
Impeller: As the core working component, the vertical axial flow pump impeller consists of blades, a hub, a water guide cone, and related elements.
Impeller casing
Guide vane: Positioned above the impeller, the guide vane primarily eliminates water flow rotation and reduces head loss while converting partial kinetic energy into pressure energy.
Foundation ring
Middle tube
Shaft protecting sleeve
Pump shaft: Transmits rotational torque to the impeller
Elbow
Bearings: Minimize the pump shaft's friction coefficient during operation
Packing box: Contains the packing seal assembly where the pump shaft penetrates the discharge elbow
Intermediate coupling: The power transmission component connecting the vertical axial flow pump to the motor, delivering motor power to the pump
Features of Vertical Axial Flow Pumps:
Optimized elbow passage with superior hydraulic characteristics.
Adjustable impeller design offering high efficiency across broad operational ranges.
Low-speed pump configuration specifically engineered for salting-out and low-temperature crystallization processes.
Vertical axial flow pumps find extensive application in salt production facilities, including brine evaporation systems and composite alkali processes. Corrosion-resistant materials and high-strength shafts are selected to ensure reliable operation and extended service life. With suction bowl diameters ranging from 225mm to 3100mm, these pumps accommodate diverse application requirements.
Custom-engineered solutions for specialized applications. Our engineering team can develop tailored designs to enhance head capacity, modify guide vane configurations, and achieve mixed-flow pump functionality. For abrasive media containing corrosive particles, wear-resistant impeller coatings significantly prolong pump service life. System modifications enable forced circulation through pressure and liquid level adjustments.
