Aside from residential properties, other fields such as construction benefit from the use of pumps. The most common pump known to most people is the sump pump, which has a physical mechanism that allows you to pump water away from a collection pit.

There are various types of sump pumps, but the most common, and reliable variant is the submersible pump. With low-noise operation and being near invisible within a home or basement carpark, these submersible pumps are a popular solution.

In this article, we’ll shed some light about submersible pumps. Read on below to learn more.

More about Submersible Pumps

As the name suggests, submersible pumps operate while fully submerged underwater, be it greywater, stormwater, or wastewater. These pumps come in handy for a range of different applications, from residential waste management to muddy water removal within the construction industry.

How Submersible Pumps Work

Submersible pumps work by using rotational energy from its spinning impeller to draw fluid and solids through into it. This is subsequently pumped out to a legal point of discharge, based off council requirements. Several components are sealed, such as the motor and electrical components that power it, to prevent internal complications. Unlike other pumps that use a pulling motion, submersible pumps use a pushing motion that pushes fluids towards the surface.

These pumps, given their names, are always submerged within the fluid. Not only does it enable them to keep themselves primed (i.e., not letting any air get into the pump which can adversely affect their efficiency), but it also allows the pumps to remain cool. The surrounding water acts as a coolant, protecting the pump’s motor from overheating and able to run for longer periods of time, minimising the likelihood of a motor burnout.

Why You Might Need a Submersible Pump

Submersible pumps are highly beneficial for homes with basements, underground carparks or where roof water is being collected in an underground collection pit. Aside from that, other projects such as basement construction can benefit from it as well, where you need to get rid of some pesky groundwater which keeps collecting down the bottom of a freshly dug hole.

If a storm or flood happens, a submersible pump (or 2, for that added peace of mind) will help because it will remove the water and any sediments brought in by the water, meaning your home won’t run the risk of getting flooded.

Sewer line problems are also handled easier thanks to submersible sewage pumps. With its capability of dealing with greywater or blackwater, it efficiently removes the waste from the property, meaning you won’t have to deal with an overflowing raw sewage line or the installation of a large septic tank.

How to Choose a Submersible Pump

Not all things are created equal, and even that applies to submersible pumps. If you want to get one for yourself, consider the following:

  • How it’s powered—are you getting a diesel pump or an electric pump? Depending on where you’ll use it, you need to know the possible options when it comes to power.
  • How big is your pump well? If you already have a pit onsite, a suitably sized pump is needed to fit your needs. – Did you know that DTB can provide a full pump station, with the pit, pump set, controller, and plumbing, all ready for a quick install? Check out our range here.
  • Are you just pumping water, or are you including solids? Not all pumps can pump out solids, like cloth, so make sure that you get one that can do so.

  • The size of the pump you plan on getting. If you’re using this pump to drain a hole, a lighter pump would be preferred over a heavier pump – Check out DTB’s builders pumps for this exact purpose.
  • How high you need the fluid to reach. Each pump is unique in how far it can carry the fluid to. Depending on the vertical height, along with the run of the pipe, a fit for purpose pump can be selected for the job.
  • The correct cord length, so you don’t have to resort to using extension cords, which also runs the risk of causing an electrical fault, which can damage the pump.
