Product Description

Product Description

Brief introduction of Vertical Axial Flow Pumps:
A vertical axial flow pump is a large vertical pump device composed of inlet channel, impeller, guide vane and outlet channel, used for conveying large flow, low head liquid, widely used in agricultural drainage and irrigation, hydraulic engineering, power plant, salt plant, chemical industry and other industries.

The vertical axial flow pump is the typical single-stage, guide vane pump with high efficiency, large flow, low head and good cavitation resistance. The pump is installed vertically, covers a small area, the blade is adjustable, the performance parameters are adjustable, and is suitable for low water level conditions, the application range is very wide.

A wide range of high-quality materials deal with different medium: 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 suitable for applications of big flow with low total head.
1. Agricultural drainage and irrigation;
2. Water supply and drainage of power station;
3. Urban flood prevention;
4. Urban water supply;
5. Water supply and drainage of docks;
6. Thermoelectricity station circulating water transferring;
7. Dock water level rising and lowering;
8. Aquaculture;
9. Saltworks draw water;
10. Salting out and low temperature crystallization of combined soda process;
11. Phosphoric acid, obtaining salt by evaporating seawater and other chemical industries.

Pump structure

Structure of the Vertical Axial Flow Pump:

 

1. Suction bell: The suction pipe of medium and small-sized vertical axial flow pump often adopts suction bell; while large-sized vertical axial flow pumps often adopt elbow or bell type suction channel, which guide the water to the impeller with minimum loss.
2. Impeller: The impeller is the main working part of vertical axial flow pump, which is composed of blade, hub, water guide cone, etc.
3. Impeller casing
4. Guide vane: the guide vane is located above the impeller, and its main function is to eliminate the rotational movement of water flow and reduce the head loss. At the same time, part of the kinetic energy of the flow can be converted into pressure energy.
5. Foundation ring
6. Middle tube
7. Shaft protecting sleeve
8. Pump shaft: Transmit torque to the impeller
9. Elbow
10. Bearings: reduce the friction coefficient of the pump shaft during rotation
11. Packing box: a packing sealing device is installed where the pump shaft passes through the outlet elbow.
12. Intermediate coupling: The connecting part between the vertical axial flow pump and the motor, which transmits the motor power to the pump

Pump features

Features of Vertical Axial Flow Pumps:

• Optimized elbow passage of better hydraulic performance.

• Adjustable impeller of high efficiency and wide high efficiency zone.

• Slowly pump speed design conforms to the technological requirements of salting out and low temperature crystallization.

• Vertical axial flow pumps are widely used in saltworks, obtaining salt by evaporating brine, composite alkali process, etc. Selecting corrosion-resistant materials and high-strength shafts to ensure smooth operation and long service life of vertical axial flow pumps. The diameter of suction bowl of the vertical axial flow pump is from 225mm to 3100mm, so it has a wide range of applications.

• Specially designed to suit different applications. With the help of our professional engineers, special design could be carried out to increase the head, increase the guide vane body, and realize the function of a vertical mixed-flow pump; Wear resistant coating is added to the impeller  for the medium containing corrosive and hard particles, so that the service life of the vertical pump is greatly extended. Increasing the system pressure and liquid level can achieve the purpose of forced circulation.

We have a long history of producing reliable operation, high efficiency, long lifetime and big diameter vertical axial flow pumps. Highly customized of vertical axial flow pumps, meet end users' requirements, as well as have lots of references of vertical axial flow pumps. For the installation of large equipment, also provide service for installation of vertical axial flow pump on site or remote technical instruction. A wide range of high-quality materials deal with different medium: cast iron, carbon steel, stainless steel SS304, SS316, SS316L, 904L, duplex stainless steel CD4MCu, 2205, 2507...

Based on CFD technology, Optimize pump hydraulic performance more efficiently.
Adopting the optimization algorithm provided by Isight, it integrates the functional optimization platform of 3D modeling software Catia, grid division software ICEM and numerical simulation software CFX.
