The submersible pump: a brief introduction

The submersible pump is sometimes called a bell pump, and is fully immersed in the liquids to be discharged: for example, to drain a cellar. Most models are fitted with an electric drive unit, but some have an electromechanical one.

What is the submersible pump used for?

The submersible pump is used for draining water: for example, for reducing groundwater, pumping groundwater to be used as drinking or fire-fighting water, pumping dirty water, and draining wastewater.

If you have a swimming pool in your garden, this pump can be used for draining it if you want to reduce the water level or add clean water. If you are dealing with a flooded cellar, for example due to leakage, this pump can be used to drain the water.

Buying a submersible pump: four tips

If you are looking for a submersible pump and want to make sure it is worth the investment,  the following four tips may come in handy for determining the best model:

Tip 1: Check pump capacity. One pump may have a capacity of 7,500 litres per hour, while another one is able to process 18,000 litres per hour. Ask yourself what capacity you require, and look for a pump with this capacity. 

Tip 2: Check the delivery head. The delivery head refers to the maximum height at which a pump can raise water.  Some pumps have a delivery head of eight metres, while others have one of five metres. Check again what you need, and find a pump that meets your requirements.

Tip 3: Consider whether the pump needs to switch on and off automatically. This is done with a float. In automatic mode, pumps are not capable of pumping a surface completely dry. This is only possible in manual mode, and you need to switch it off in time.

Tip 4: Check which accessories are supplied with the pump. Some pumps are more user friendly than others, simply because they come with more accessories. If you consider ease of handling very important, we advise you to check which accessories are standard with the pump.

With the above tips in mind, you will definitely find the submersible pump most suitable for your needs.
