What Is a Submersible Pump and Why Should You Use One?

Posted on Saturday, October 3, 2020

Submersible pumps, such as those manufactured by HydroFlo Pumps, have various benefits that make them ideal for commercial, residential, and industrial operations. Understanding what these pumps are and how they work is the first step towards choosing the best pump for the job you need. As a leader in the design, installation, and maintenance of pumps, Zone Industries will work with you to find the perfect solution for your needs.

What a Submersible Pump Is

Submersible pumps have airtight sealed motors that have several advantages for certain pumping applications. A high-quality submersible pump, such as Allflo Pumps, should never need to be taken out of the liquid it is submerged in. Because the liquid the pump is submerged in primes the pump, the pumps never need to be manually primed.

Uses for Submersible Pumps

Because HydroFlo Pumps are made to fit in difficult spaces, these pumps can be a good choice for places that are difficult to access or confined. These pumps are also good choices for wells. The ability to place the pump directly in the water source makes it easier to efficiently pump high-quality water into your home, worksite, or business. Additionally, these pumps are useful for draining fields, managing pond filtration, moving sewage and oil wells.

How Submersible Pumps Function

Submersible pumps, such as a vertical turbine pump, function by changing rotary energy into kinetic energy. The pump accomplishes this by using the pressure energy drawn in by the pump. The liquid enters the pump through the intake and is then pushed through the impeller and into the diffuser. After passing through the diffuser, the fluid can flow to the surface, where it can then be used for whatever purpose you need.

The hydraulic motors in these pumps are usually closed-cycle pumps but can also be open-cycle. Whether closed or open, the motors function similarly. These vertically positioned pumps can generate large amounts of pumping power.

Requirements To Use the Pumps

The pump will need to be submerged permanently; otherwise, it could overheat or sustain other damage. However, the issues are usually minor, so while it is a good idea to keep the pump submerged, you do not need to go to extremes to submerge your vertical pump.

Advantages of Submersible Pumps

To get maximum benefits from a submersible pump, it is wise to choose a manufacturer known for high-quality pumps, such as Crane Pumps. Top-quality pumps have numerous advantages:

  • These pumps do not use very much energy compared to other similar pumps. Because of this energy efficiency, submersible pumps are a good choice for budget-conscious homeowners and businesses
  • Because you do not need to prime these pumps, they are lower maintenance and easier to operate than other types of pumps
  • These pumps do not experience cavitation or spikes in pump pressure. Additionally, because they are submerged, the liquid serves as a sound barrier, making these pumps very quiet to operate
  • If you have a lot of different jobs to be done, these pumps are a good choice because of their versatility

Disadvantages of Submersible Pumps

We believe that these pumps’ advantages outweigh the disadvantages, but it is still important to be aware of potential drawbacks. There are a few limitations you should consider when choosing a pump:

  • While these pumps are useful in many different applications, they are not the best choice for every job. Your Zone Industries representative can help you determine whether a submersible pump is a good fit for the job you need to do
  • Because the pumps are constantly exposed to liquids, some of which may be corrosive, the seals can break down, which may lead to damage to the motor
  • The liquid surrounding the pump usually keeps the pump cool, but if the liquid dries up, your pump could overheat. You may need to be cautious when using these pumps in wells or other applications where there is a significant danger of the liquid drying up
