When shopping for a pump there are many things you need to consider, such as the flow rate, the uplift capacity, or even whether they will work underwater. It’s a good idea to get some professional help to ensure you choose the best pump possible for your needs.

One key decision you need to make is whether to invest in submersible pumps or not.

What the Submersible Pump Does

As the name suggests, a submersible pump can be used underwater. If your pump isn’t submersible it’s likely to be waterproof and capable of pumping water in the rain but not able to work under the water.

However, in many situations having a pump that works underwater makes sense. Let’s take a look at the advantages and disadvantages of a submersible pump.

Works Underwater

If you’re mining or simply seeking to protect your home from being flooded then a submersible pump doesn’t just make sense, it’s essential. The pup can be located at the lowest point of the mine or your home. It will then remove the water even when it is fully submerged.

In a working situation, this can help you to see what you’re doing. At home, it can ensure the water is pumped out of your home before it causes extensive damage.

No Priming

Submersible pumps are designed to start as soon as the sensor detects the presence of water. They don’t need to be primed or have any human interference. They are already below water level which means they are primed and can start straight away.


A submersible pump turns on and off as needed reducing your running costs in comparison to monitoring one and manually turning it on and off. But, they also maintain liquid in the head of the pump. This is because they are underwater and it improves the suction in the pump. Consequently, they need less power to work efficiently, again saving you money.


Submersible pumps don’t make a lot of noise and the noise they generate is likely to be absorbed by the water they are sat in. In other words, they’re going to sound virtually silent. The same cannot be said for non-submersible pumps.

You should note that it is not always easy to get to a submersible pump. At home, the t may be shallow making access comparatively easy. But, in many situations, the pump is much deeper in the ground, such as in the well. This can make it very difficult to inspect them or provide routine maintenance.


Pumps that sit in water are more likely to experience corrosion of their parts. Water and metal don’t mix well. Add in the minerals in the water and even the pipes can perish quicker than expected. To eliminate this issue the pumps need to be made of corrosion-resistant material. This increases the cost of manufacturing and subsequently purchasing the pumps.

That’s an important consideration if your budget is limited. Although, with good maintenance, submersible pumps should last longer than non-submersible ones.
