When to Use Horizontal-Shaft Axial Flow Pump?

24, Feb. 2025

 

What is horizontal axial flow pump

Horizontal axial flow pumps are commonly used in applications where a large volume of fluid needs to be moved, such as in irrigation systems, drainage systems, and wastewater treatment plants. They are also used in cooling systems for power generation plants, as well as in marine applications such as ship propulsion.

These pumps are typically designed to handle low head applications and may have multiple impellers to increase the flow rate. They are often more efficient than other types of pumps, particularly for low head and high flow applications, but they may not be suitable for high pressure applications.


How does it Horizontal axial flow pump works ?

A horizontal axial flow pump works by using a rotating propeller-like impeller to move fluid along the shaft of the pump. The impeller is typically housed in a cylindrical casing and is mounted horizontally, parallel to the ground.


When the impeller rotates, it creates a low-pressure zone at the center of the pump, which draws fluid in through the inlet of the pump. The impeller then forces the fluid outward, generating a high-volume, low-pressure flow of fluid in a horizontal direction.


The direction of flow is parallel to the axis of the pump, hence the name axial flow. The fluid is pushed through the impeller blades and into the discharge volute, which is designed to channel the flow in a specific direction.


One of the key advantages of a horizontal axial flow pump is that it can handle large volumes of fluid with relatively low power consumption. This makes it an ideal choice for applications where a high flow rate is required, such as in irrigation systems or water treatment plants.


However, it is important to note that the pressure generated by a horizontal axial flow pump is typically lower than that of other types of pumps. As a result, it may not be suitable for applications where high pressure is required, such as in some industrial processes.


Uses Of Horizontal axial flow pump

Horizontal axial flow pumps are used in a variety of applications where a high volume of fluid needs to be moved horizontally. Some of the most common uses of horizontal axial flow pumps include:


1. Irrigation Systems: Horizontal axial flow pumps are used to move large volumes of water for irrigation purposes in agriculture.


2. Drainage Systems: They are used to remove excess water from flooded areas, such as fields or construction sites.


3. Water Treatment Plants: These pumps are used to move water in large quantities for treatment and distribution.


4. Cooling Systems: Horizontal axial flow pumps are used in cooling systems for power generation plants, refineries, and other industrial applications.


5. Marine Propulsion: They are used as the primary propulsion system for ships and boats, such as barges and tugboats.


6. Flood Control: Horizontal axial flow pumps are used in flood control systems to move water from low-lying areas to higher elevations.


7. Mining: They are used in the mining industry to move large volumes of water and other fluids from mines.


8. Fish Farms: They are used in aquaculture to move large volumes of water to create the right conditions for fish growth.


In general, horizontal axial flow pumps are ideal for applications where a high flow rate is required, but the pressure requirements are relatively low. They are also well-suited for applications where space is limited, as they can be mounted horizontally, which requires less vertical space than other types of pumps.


Advantages Of Horizontal Axial Flow Pump

Horizontal axial flow pumps offer several advantages over other types of pumps, including:


1. High Flow Rate: Horizontal axial flow pumps can handle high volumes of fluid with relatively low power consumption. This makes them an ideal choice for applications where a high flow rate is required.


2. Efficient: They are more efficient than other types of pumps, particularly for low head and high flow applications.

3. Space-Saving: The horizontal orientation of the pump allows for a more compact design, which can save space in installations where vertical space is limited.


4. Low Maintenance: They have a simple design with few moving parts, which results in low maintenance requirements and reduced downtime.


5. Cost-Effective: Horizontal axial flow pumps are typically less expensive than other types of pumps, making them an economical choice for applications where a high flow rate is required.


6. Easy to Install: They are relatively easy to install and can be used in a variety of applications.


7. Low Noise: The horizontal axial flow pump operates with low noise, making it a good choice for installations where noise is a concern.


Overall, the horizontal axial flow pump is a reliable and efficient pump that offers many advantages over other types of pumps. Its high flow rate, low maintenance requirements, and space-saving design make it a popular choice for a wide range of applications.

Explanation of horizontal axial flow pump (EHT) for flooding and ...

Axial flow pump  (EHT) for flooding and irrigation use.
Axial flow pumps are often constructed with horizontal shaft and with suction and discharge lines or concrete inlet and outlet canals. The advantages of this type of construction are that the pump can be placed on a simple foundation and provides easy accessibility for inspection. After removal of the top half of the pump casing the impeller can be easily mounted and dismounted. In this respect the water does not present any difficulties, since in this construction the impeller is as a rule located above the highest water level or else a valve is provided on the discharge side. Hence, it is not necessary to dam off or drain any part of the canal.

The pumps of this type can be built for very large capacities. When the impeller of a pump is located above the suction water level it is necessary to draw the line full of water before starting up the pump. Evacuation of the suction line is usually effected by means of a vacuum pump.
