A submersible water pump, often called a ‘bell pump’, operates fully submerged in water. Unlike traditional pumps, which draw water up through a suction, a submersible pump pushes water up through a discharge outlet. They’re used to remove excess water in the event of flooded basements and boats, for example.  

They’re also a much more efficient option as they eliminate air leakages and reduce energy loss. Plus, they feature sealed motors for full underwater protection. 

How do submersible sump pumps work? 

A suction grid on the base of the pump forces the water directly into the system. Once inside, the water is pushed through the pump by an internal impeller. It then departs through a connected discharge hose and into a tank. 

As the pump is surrounded by water, it naturally stays cool and rarely overheats. However, bell pumps should never run completely dry. If this happens, the motor is at risk of burning out.  

You’ll commonly find submersible pumps in: 

• Construction sites 

• Wells 

• Draining systems 

• Garden ponds and fountains 

• Irrigation systems 

What is a submersible water pump used for? 

A submersible water pump is designed to move water from one place to another. 

Here are some of the most common uses:  

• Wastewater management (reducing groundwater) 

• Water supply (e.g. for fire-fighting or swimming pools) 

• Drainage 

• Agriculture 

• Separating sewage and waste  

• Pumping from wells 

• Seawater handling  

The benefits of submersible sump pumps  

There are many reasons why you should be investing in a submersible sump pump. Here are just some to keep in mind: 

Less noise  

As submersible pumps run underwater, they’re operationally quiet. This makes them ideal for use in homes and businesses, without disruption. 

Boosted efficiency 

As these pumps operate underwater, the water pressure draws in the liquid automatically. Therefore, very little energy is used, which cuts costs. 

No need for extensive setup  

Typically, traditional pumps require extensive setup. However, submersible pumps don’t require any maintenance due to operating underwater. 

Less maintenance 

A bell pump is unlikely to get clogged with debris and break down, due to its underwater position. A submersible pump requires minor maintenance as opposed to above-ground models. 

On average, a submersible sump pump has a 10-year lifespan. There are certain tasks you can carry out to keep your pump running like clockwork. If you would like further advice on general pump maintenance, we’d be happy to advise. 

They’re space-saving  

Bell pumps are super compact. Plus, as they’re underwater, you won’t be losing valuable floorspace. Therefore, they’re ideal for homes or businesses where there are space constraints.
