What Are Submersible Pumps and How Do They Work?

Submersible pumps have developed as critical pieces of equipment for effective fluid control. These pumps are extremely versatile and dependable. They are used to dewater building sites, control sewage, and irrigate farms, among other things. 

In this blog, we will look at what submersible pumps are and how they might be used. MB Exports one of the best submersible dewatering pump manufacturers in Australia. We have self-priming pumps, self-priming garbage pumps, and self-priming regenerative pumps available.

What is a submersible pump and how does it work?

Self-priming submersible pumps ensure quick and efficient operation. The motors of these pumps are hermetically sealed. They allow the pumps to be immersed completely without risk of electrical damage.

These pumps work by converting electrical energy into mechanical energy via an electric motor. They are intended to be completely submerged in the fluid being pushed. 

This motor is used to power an impeller, which is a revolving component with curved blades. The centrifugal force created by the rotating impeller pulls the fluid away from the centre. This causes pressure. The fluid is then guided and regulated by a diffuser, which is a stationary component that guides and regulates the flow. 

It changes low-pressure, high-velocity flow into high-pressure flow. The high-pressure fluid is discharged through an exit or into a pipe network, allowing for efficient fluid transmission.

Submersible pump applications

Mining, agriculture, oil and gas, chemical processing, and manufacturing all use submersible pumps. Corrosive liquids, slurry, and abrasive materials are no match for them. This makes them excellent for difficult industrial conditions such as muddy excavations, sewers, mines, and even damp sumps. 

Here are the uses: 

Dewatering Submersible pumps:

Submersible pumps are frequently used in dewatering applications. They are responsible for removing water from building sites, mines, basements, and flooded areas. In these instances, their capacity to work when submerged makes them extremely effective.

Management of wastewater and sewage:

These pumps efficiently pump sewage and wastewater from residential, commercial, and municipal sources. They ensure that waste is properly treated and disposed of.

Agriculture and irrigation:

The pumps aid in the delivery of water to fields from wells, rivers, or storage tanks. They ensure optimal crop growth and water delivery.


These pumps enable efficient water circulation and aeration for fish and shrimp farms. Not only that, but by preserving optimal water quality, they contribute to the creation of a healthy environment for aquatic life.

Water supply and domestic use:

They are commonly utilised in residential, commercial, and municipal settings for water supply. They efficiently pull water from wells, boreholes, or underground sources, ensuring a steady and dependable supply of water for everyday use.

Geothermal energy:

Geothermal fluids are extracted from deep underground using pumps. They are resistant to high temperatures and corrosive fluids, which are prevalent in geothermal applications.

There are numerous examples of how submersible pumps contribute to increased operational efficiencies. Imagine a pumping station, for instance, has four pumps, each powered by a 900 horsepower engine, according to the above-base discharge. This also includes a 66-inch elbow. The distance between the base plate and the top of the elbow is 7.5 feet. 

The motor is positioned on top, with a height of 18 feet to the base plate. For working on the equipment, the platform should be created around this motor. However, if the motor malfunctions, it may take 1-2 days to remove the platform and retrieve it. An electric submersible propeller pump, on the other hand, will perform the job properly, taking only half an hour to install and solve the problem. 

Furthermore, depending on the installation, these pumps are available in horizontal, vertical, or angled configurations. This is useful in clubs and other public places where customers set up pumping stations but do not want the equipment visible to visitors. 

What are the benefits of using a submersible pump?

A submersible pump has numerous benefits. Among them are the following:  

  • They are quite efficient. As a result, energy usage and running costs are lowered.
  • Submersible pumps’ compact design allows for easier installation in limited and smaller spaces. It is also easier to handle than many ordinary rivals. 
  • They are silent devices with low vibrations.  As a result, they are appropriate for noise-sensitive situations.
  • Submersible pumps provide dependable operation and a long lifespan due to their sealed motor design.
  • They are adaptable and can tolerate a wide variety of fluids. As a result, they are suitable to a wide range of industries and pumping requirements.
