A submersible pump is commonly used in a variety of home water systems. This type of pump is, as the name suggests, fully submerged in water for its pumping tasks. It features a hermetically sealed motor that is close-coupled to the pump’s body.
The main purpose of such a pump is to push water to the surface. It does so by converting rotary energy to kinetic energy, and then kinetic energy into pressure energy. This occurs when the water is pulled into the pump. First the water comes into the intake, where a rotating impeller pushes the water through the diffuser. After it passes through the diffuser, the water can then go to the surface.
Here’s some information about the primary advantages and disadvantages of using submersible pumps in your water systems in Hillsborough County, FL.
Advantages of Submersibles
Perhaps the biggest advantage of using a submersible pump is that you never have to worry about priming it, because the pump is already underneath the fluid. However, there are plenty of other advantages to consider, as well.
For example, submersible pumps are extremely efficient. They do not require much energy to move water into the pump. The water pressure naturally pushes the water inside the submersible pump, which saves a lot of energy in comparison to other kinds of pumps you might use.
Cavitation won’t be an issue with submersible pumps, because there isn’t a spike in water pressure that occurs as the water flows through the pump—just another benefit of the water naturally flowing into the pump.
While the pumps might not be particular versatile in their uses, you will absolutely find a versatile selection of them. There are some submersible pumps that are designed to handle solids as well as liquids, while others are designed for liquids only.
In addition, submersible pumps are much quieter than other types of pumps because they operate under water.
Disadvantages of Submersibles
For all of the positives, there are a few disadvantages associated with the use of submersible pumps.
Two of these disadvantages are with the seal, which can become corroded over time. If you have a corroded or damaged seal, water can start to get into the motor, which can render the motor inoperable until you’ve repaired both it and the seal. The seal also makes the pump itself more difficult to access if you have repairs you need to make.
The submersible pump also does not fit all sizes. You can find single-stage pumps you can use in most home and light industrial pumping scenarios, such as sewage pumping, filters in aquariums and sump pump drainage. There are multiple stage pumps that can be used underground for water and oil wells. But in general, you won’t find a one-pump-fits-all sort of situation.
This should give you a decent idea of what a submersible pump is and how it’s used, as well as why or why not you might choose one. For more information about pumping and water systems in Hillsborough County, FL, contact us today.
