What is a submersible pump and how to choose one?

A submersible pump enables you to draw water from great depths (deeper than 8 metres). It is submerged deep within the water in a well or a drilling site and operates on the suction principle. Its use may vary from the supply of domestic water to more specific requirements such as for watering a garden or for agricultural irrigation, for example.

Thus, there are various models with differentiating elements such as the flow rate, power or electrical voltage (230 V, three-phase, etc.), the material used for the pump body (stainless steel, cast iron, Zamak, etc.) or even the discharge head.

The presence of a check valve as well as the concept of protection against overheating, the presence of a safety mechanism for a lack of water are also criteria to be taken into consideration.

All our technical data sheets available on our website contain the precise characteristics of our pumps. Our experts are also at your disposal to answer your questions or provide you with assistance for accomplishing your project.

Different types of submersible water pumps on offer

With a few specific exceptions, there are two major groups of submersible pumps. One contains drainage pumps (see our article of choosing a drainage pump) and the second consists of submersible pumps for deep wells and drilling sites. Regardless, keep in mind that a immersed pump is also a submersible pump.

Immersed pumps or drainage pumps for rainwater and other types of water to be pumped.

To drain rainwater, clear water or even water with larger particles (waste water, turbid water, very turbid water), it is necessary to use a drainage pump that is also a submersible pump. This group of pumps includes submersible pumps for wells, irrigation pumps and garden pumps in particular.

Unlike a surface pump such as the JET model from our range, a submersible pump for wells (lift pump) will, for example, is able to lift water from a well with a depth of more than 7 metres.

There are also submersible lift pumps with built-in floats that allow the pumps to be turned off so that they do not run dry. Knowing and understanding the choice of impeller in the pump is also important for a submersible pump because this will be the factor on which the type of water that can be pumped will depend. Single-channel, diagonal, closed impeller, etc. There are several types of impellers for pumps.

Submersible water pumps for pumping domestic water are most often equipped with cutting impellers. This is often the case for submersible pumps for wells. Vortex impeller models are recommended for transporting waste water.

Submersible pumps for drilling sites and submersible pumps for deep wells

The second group includes immersed pumps for drilling sites and pumps for deep wells. We offer submersible pump models (bore-hole pump) that can reach up to 20 metres and even close to 40 metres deep with an extended service life.

If you choose this type of pump, it is necessary to ensure that the submersible booster pump or even your pressure booster unit is designed for intensive use. The anti-lock safety on this type of equipment will be a sizeable advantage for the longevity of your installation.
