What are Submersible Pumps: A Thorough Guide

Submersible pumps have emerged as essential equipment for efficient fluid management. These pumps offer exceptional versatility and reliability. They are used for dewatering construction sites, sewage management, agricultural irrigation, etc. 

In the article, we will explore what are submersible pumps and what are their applications. If you’re looking for efficient and versatile pumping equipment, explore DAE Pumps. We have a range of self-priming pumps, self-priming trash pumps, and self-priming regenerative pumps.

What is a submersible pump and how does it work?

Submersible pumps are self-priming devices, ensuring quick and efficient operation. These pumps are equipped with hermetically sealed motors. They allow the pumps to be fully submerged without the risk of electrical damage.

These pumps operate by using an electric motor to convert electrical energy into mechanical energy. They are designed to be fully submerged in the fluid that is being pumped. 

This motor drives an impeller, a rotating component with curved blades. The spinning impeller creates a centrifugal force that pushes the fluid away from the center. This generates pressure. The fluid is then directed through a diffuser, which is a stationary component that guides and regulates the flow. 

It converts high-velocity, low-pressure flow into high-pressure flow. The high-pressure fluid is discharged through an outlet or into a connected pipe system, which enables efficient fluid transportation.

Submersible pumps are useful for varied applications

Applications of submersible pumps

Submersible pumps are used in mining, agriculture, oil and gas, chemical processing, and manufacturing. They easily handle corrosive liquids, slurry, and abrasive materials. This makes them ideal for challenging industrial environments like muddy excavations, sewers, mines, and even wet sumps among others. 

Here are some of their applications: 

  • Dewatering: Submersible pumps are commonly used for dewatering applications. They remove water from construction sites, mines, basements, and flooded areas. Their ability to operate while being submerged makes them highly effective in these scenarios.
  • Wastewater and sewage management: These pumps efficiently pump sewage and wastewater from residential, commercial, and municipal sources. They ensure proper treatment and disposal.
  • Agriculture and irrigation: The pumps help deliver water from wells, rivers, or storage tanks to fields. They ensure optimal water distribution and crop growth.
  • Aquaculture: These pumps provide efficient water circulation and aeration for fish and shrimp farms. Not just this, by maintaining optimal water quality, they help to create a healthy environment for aquatic life.
  • Water supply and residential usage: They are widely used for water supply in residential, commercial, and municipal settings. They efficiently draw water from wells, boreholes, or underground sources, thus providing a consistent and reliable water supply for daily usage.
  • Geothermal energy: The pumps are utilized to extract geothermal fluids from deep underground. They can withstand high temperatures and corrosive fluids commonly found in geothermal applications.

There are countless examples of how submersible pumps contribute towards higher operational efficiencies. For instance, suppose a pumping station has four pumps with 900 horsepower motors as per the above-base discharge. This comes with a 66-inch elbow as well. 7.5 feet is the measurement from the base plate to the elbow top. 

The motor is positioned on top, with the measurement being 18 feet till the base plate. The platform should be built around this motor for working on the equipment. However, whenever the motor has any issues, it may take 1-2 days for taking the platform down and retrieving the same. However, an electric submersible propeller pump will do the job perfectly, requiring only half an hour for installation and solving this problem. 

Also, these pumps come in horizontal, vertical, or angled versions depending upon the installation. This is helpful in clubs and other areas where customers set up pumping stations and do not want the equipment to be visible to visitors.

Frequently asked questions about self-priming pumps

1. What is the minimum water level for a submersible pump?

Submersible pumps operate on the basis of a minimum depth or water level. Based on estimates, they pump out water up to 15 centimeters in this regard. This is the average threshold worth noting in this case. The minimum water level should be carefully ascertained before operations, since it plays a vital role in various applications. 

2. Are self-priming pumps suitable for temporary applications? 

Yes, self-priming pumps are ideal for temporary pumping needs. This is because they can quickly prime and start pumping without the need for manual priming. These pumps can be accessed easily and have numerous kinds of applications. Temporary applications are often a bugbear for companies and these pumps can help address these requirements minus any hassles. 

3. Do submersible pumps require regular maintenance?

Submersible pumps are generally low-maintenance products. So periodic inspections and cleaning of the pump and its components are recommended to ensure optimal performance and longevity. This will keep the pump in good condition for several years to come. Get in touch with the manufacturers or check their manual for maintenance.

4. Are self-priming regenerative pumps suitable for high-pressure applications?

Yes, self-priming regenerative pumps are known for their ability to generate high pressures. This makes them suitable for tasks requiring high-pressure pumping, such as irrigation and water supply systems. These are highly specialized kinds of pumps and you should keep an eye on the key features and benefits before your purchase.
