What Is a Submersible Pump, and What Are The Benefits?


March 8, 2021

If you have recently come into possession of a property that features a basement, or even been the victim of a basement leak recently, and you are wondering what the best course of action is when it comes to safeguarding your property against any future damages.

In both situations, your findings are probably going to lead you towards the possibility of having a submerged pump installed in your basement.

Now, if you have never had to learn about the different kinds of pumps available for your home before then it can all seem quite daunting to start off with, but don’t worry: We are here to help, and to explain exactly what a submerged pump is, how it can help out in your home as well as the benefits of having a submerged pump installed.

What is a Submersible Pump?

As you might have guessed from the name, a submersible pump is one that is designed to be immersed in the substance that the pump itself is designed to be pumping.

A submersible water pump would be fine if immersed in water, a sewage pump in sewage and so on.

This is because all of the vital components that keep the pump working are hermetically sealed away from where they can be damaged by the water itself.

This means that your pump can function completely normally, even when its surrounded by liquid. Generally speaking, these types of pumps operate using kinetic energy.

It pushes the liquid (whatever it may be) through its system by having rotary energy generated by the pumps motor converted into kinetic energy, which in turn forces pressure energy.

The resulting effect is that water is pulled into the pump through the intake, pushed by the rotation of the motor, and then forced through the diffuser and out of the pump into whatever system that the liquid is being channelled to. I mentioned just that the contents usually being pushed through a submersible pump are liquid, but that isn’t true in every instance.

In fact, certain types of submersible pumps (mainly sewer pumps) are entirely capable of pumping solids, as and when they are required.

One way that nearly all submersible pumps are alike though is in the fact that they are capable of running without any user input.

This is usually due to these pumps being sealed by their very nature, and complicated in their machinery and application.

Instead, once they have been installed, they will operate on a dependable power supply, with alarms to alert the occupier if there is an issue outside of regularly scheduled maintenance.

If you are looking for a bottom line in this section though, its this: A submersible pump is a type of pump that sits in the ground of your property, entirely capable of being submerged in the materials it is expected to pump, operating independently of user input effectively.

The Different Types of Submersible Pumps

Speaking honestly, there are hundreds of different types of submersible pumps, ranging from commercial engineering and mining to pipeline management and infrastructure purposes. As a property owner though, the only types of submersible pumps you really need to be aware of are the sump pump and the sewage pump.

Sewage Pumps

A sewage pump is exactly what it sounds like: a pump designed to funnel and channel a property’s sewage into the correct sewers and drains around the property when a buildings plumbing isn’t capable of doing so independently.

You will often find sewage pumps connected to the likes of septic tanks, within homes that are too low to take advantage of gravity-reliant drainage, or within commercial properties that require additional pumping solutions within their sewage systems.

All in all, a sewage pump is vital if your property is prone to drainage or sewage issues including clogs, flooding or overspilling. In fact, you can even expect sewage pumps to come in a variety of different types, as their actual application can differ depending on the type of property they are installed within.

Sump Pumps

You then have sump pumps. Whilst these are similar to sewage pumps, they are different. You can read more about the differences between sewage and sump pumps, as well as their different individual types, right here, but I will give you a quick rundown of a sump pump here.

Whilst sewage pumps are focused on pumping away sewage and are capable of handling solids at certain points, a sump pumps only purpose is to channel water away from a property. The water a sump pump is going to be pumping is specifically that which manages to leak into a basement. Now, a sump pump will usually be installed as part of a type C waterproofing solution.

A type C waterproofing solution involves the application of a waterproof cavity membrane to the walls of a basement. This then allows any water which makes its way through the exterior walls is trapped by this waterproof layer, and safely collected in a perimeter drainage channel that leads into a sump pump, which in turn pumps the water away from a property.


Basically, no type C waterproofing system can exist without a properly functioning sump pump, as if the sump pump doesn’t do its job for whatever reason, then water will collect within the pump chamber and waterproofing drainage system, leading to potential flooding – which comes with its own host of problems.

Instead, a sump pump is relied on by many to make sure that the water within their basement is always being moved out and away from their property, so that it never has to be worried about. If you are considering the installation of a submersible pump though, what are the advantages you should be aware of?

The Advantages of a Submersible Pump

The very first thing you need to understand about a submersible pump is that it is a complicated piece of engineering. You need to make sure that it is installed by qualified professionals, and in doing so you will have peace of mind in that the pump in your property is going to be working seamlessly and fault free without your intervention at any point. In fact, as a property owner, you should expect the bare minimum to no contact at all with your submersible pump.

Usually, they are connected safely to their dependable power source and feature an alarm for dire emergencies, but otherwise, you should never have to notice that they are working. Outside of the obvious benefit of having your property defended against potential sewage or basement leaks, you can also expect your submersible pump to be very energy efficient as they expend very little energy in getting their relevant materials into themselves.

Instead, thanks to the perimeter drainage system that will be in place already, you will be able to count on gravity and water pressure to do a lot of the work for the pump, making your overall costs of using a submersible pump very low.

One thing you will need to be aware of however is that in order to maintain maximum trust and operational efficiency, submersible pumps need to be maintained on a regular basis.
