Everything You Need to Know About Submersible Pumps

The emergence of technological innovation in the space of wastewater management has given rise to solutions that help industries and homeowners to reduce water waste and become more sustainable.

Today, we use different tools and casing and piping options to make our work easier – OCTG casing, submersible pipes are just to name a few.

When we talk about pumping fluids from the ground, we know that energy, cost, and productivity are key. Pumping water from the ground could be a daunting task. Hence, we have the facility of application of submersible pumps. In this guide, we will provide you with ample details on the submersible pumps so that you are not only able to enhance your knowledge about them but also able to buy the best pump as per your needs.

 

 

Design

The pump has a tight enclosure around the motor, which does not allow water to enter the body of the motor, protecting the motor from catching short circuits. The enclosure is covered with oil, which is what resists the liquid from bypassing the enclosure and entering the body and damaging it. A submersible pump’s motor is attached to the pump’s body.

What is more exciting about the submersible pump is that it does not function with the usual water draw technique. Instead, it first pushes the water and then draws it. This saves a lot of energy than those pumps that directly draw the water. It is also interesting that since the motor and the body of the pump remain submerged in the water, the water around the body of the motor and the pump keeps it safe against risks of overheating.

What are Electronic Submersible Pumps (ESPs)?

Most of the submersible pumps that have been applied in the gas and oil extraction domain use the Electric Submersible pumps. The motors for these pumps are expensive and are usually designed to operate under high temperatures and ensure smooth drawing of the fluid at the discharge point. It is a cost-effective technique for pushing and drawing large amounts of liquid in no time.

Benefits

  • The second benefit is relevant to cavitation. Cavitation is the corrosion of water vapors that appear on the surface of the shaft of the motor. Since the motor and pump is submerged in the water and has protective layers of oil and watertight enclosures, these pumps are not prone to cavitation
  • Another great benefit is that since the pump is submerged in the water, it does not make noises when in operation
  • Since there is high pressure at the suction level, drawing the liquid does not require much energy, which results in efficient working.

Areas Where the Pump Underscores

  • Although these pumps are cheap, prolonged exposure to water or abrasive substances can lead to easy corrosion. In addition, corrosion-resistant enclosures are expensive and may certainly push up the price of these pumps, making them equivalent to more expensive pumps on the market
  • Timely Careful Inspection is not easy, which risks the safety of the investment
  • On the downside, submersible pumps are usually installed underwater and often at great depths. Replacing materials or repairing and maintenance is quite rare. Hence, usually, these pumps are often left to corrode and stop functioning properly

Applications

Some of the useful applications of borewell submersible pumps include bringing up water for the fountain. This seems a cost-effective way for fountain maintenance since submersible pumps use a minimum amount of energy to transport the water upwards. These pumps also have applications for irrigation farming since they are cheap, fast, and highly reliable. Other useful applications include pushing and drawing liquid for dredging applications by port authorities. The application of ESP is very beneficial for the exploration of natural resources from wells.

Things to Consider Before Buying a Submersible PumpĀ 

To help you procure the best quality submersible pumps, we have included a very helpful buying guide so that you do not only buy the best quality pumps but also procure them at the best possible rates. We have summarized the key features you need to consider before buying a submersible pump:

  • Consider a pump that fits in the size of your borewell as choosing otherwise would result in the pump not settling in the borewell
  • Consider a pump that can transport and draw the water to an ideal height as per your needs
  • Select a pump that has a suitable discharge rate, which is the amount of water that could be pumped from the borewell within a minute
  • Have a close look at the efficiency chart of the pump by checking the quality and functionality of the motor
  • The size of the pipe connected to the motor must fit in the borewell or the connector in the tank

Conclusion

In a nutshell, a submersible pump saves a lot of energy than those pumps that directly draw the water. It is also interesting that since the motor and the body of the pump remain submerged in the water, the water around the body of the motor and the pump keeps it safe against risks of overheating.
