Advantages and Disadvantages of Submersible Pumps

October 23, 2020

A submersible pump is a type of pump that is intended to move liquid or another medium from one point to another while it is submerged in the medium. The motor of this pump is enclosed with a water-tight enclosure to effectively prevent the entry of liquid inside. The risk of overheating while this pump is operating is likewise averted due to the liquid that surrounds it. This type of pump normally works by pushing the liquid during the process of pumping. 

Many industries utilise the capabilities of submersible pumps since they can work under harsh or extreme conditions. Some of the industries that maximise these pumps include grit and wastewater, agriculture, construction, mining, and marine. Without submersible pumps, it would be impossible for some of these industries to work optimally and efficiently.

To know more about submersible pumps, here are some of their known advantages and disadvantages.

Advantages of Submersible Pumps

One of the notable advantages of submersible pumps is that they can effectively resist the damaging effects of being submerged in any liquid medium. These pumps are comprised of a housing that can resist corrosion and abrasion. They likewise have watertight gaskets and seals that can easily prevent water from flooding their motor and other internal components. The presence of these vital parts helps the pumps avoid leaks and electrical issues whenever they operate.

Another advantage of submersible pumps is that they can operate more effectively than other types of pumps. Instead of drawing the liquid into the pump, submersible pumps use direct pressure from the pipe or hose to push the fluid out. This functionality is possible since these pumps are placed inside the liquid. With this specific function, submersible pumps do not only save a lot of energy, but they can also cover more distance of a specific setting or application.

Some types of pumps must be primed first for them to start operating. Submersible pumps, on the other hand, do not have to be primed. These pumps are known for their self-priming capability as they work and operate below the surface of the medium that is intended to be pumped. And since they are submerged, submersible pumps can be very quiet during their normal operations.

Disadvantages of Submersible Pumps

Even with the mentioned advantages, submersible pumps still have their own set of drawbacks. For one, submersible pumps can still be prone to leaks and operation failures due to weary gaskets or corroded seals. These components help prevent water from getting inside the pumps. However, once they have deteriorated in quality, they cannot drive the water out of the pumps anymore.

Routine inspections, maintenance, and repairs may be also difficult with submersible pumps as they are submerged inside water. In some instances, submersible pumps are installed in locations that are truly deep and difficult to reach. This difficulty alone allows some applications to just let the pumps work without checking their condition and status regularly. Skipping their needed assessment and preventive maintenance will then compromise their service life in the long run.

Considering the advantages and disadvantages of submersible pumps is important to determine if you truly want them to be used for your intended or proposed application. For more information about these pumps, feel free to contact us at Parker Pumps.
