What is a swimming pool filtration pump?

A swimming pool, what a pleasure! Sparkling, clear water that invites you to take a dip is the hope of the whole family. The main player in this perfect picture is undoubtedly the filtration of the pool, it is less enchanting but essential. No good filtration without an efficient and appropriate filtration pump. Knowing what is a swimming pool filtration pump is essential so that the pump is in perfect harmony with the characteristics of the swimming pool and thus satisfy bathers.

The filtration pump and circulation of pool water

Stagnated water is synonymous with green water. Without movement, algae takes hold and transforms a swimming pool into a duck pond. Grasses, leaves, twigs, dust, etc. settle at the bottom of the pool, remain there, decompose and pollute the water. It is the filtration pump which will breathe and create the mobility of the water and thus help to keep it clear.

The filtration pump and water circulation

The filtration pump is the engine, the filtration system of the swimming pool and it ensures the circulation of water in the pipes and the swimming pool.

The water is sucked up mainly by the skimmers and to a lesser extent by the bottom drain, passes through the pre-filter of the pump which retains the largest impurities, then through the filter. By the power of the filtration pump, the clean water is directed to the automatic treatment then to the heating system (if these two pieces of equipment exist). Finally, the water is propelled into the pool via the discharge nozzles. The latter are oriented so as to direct the impurities which float on the surface of the water towards the skimmers. The cycle continues as long as the pool filtration is working. Thus, the swimming pool filtration pump contributes to the cleanliness of the water, but its role is not limited to that.

The swimming pool filtration pump and water treatment

The swimming pool filtration pump ensures the mechanical diffusion of water treatments, thanks to the movements it creates.

This concerns the balance of the water, when we add corrective products such as pH (more or less), powder to increase the alkalinity level, or when adding a stabilizer.

Whether the water treatment is manual or automatic, the filtration pump guarantees the good dispersion of disinfection products such as chlorine, active oxygen... or even the diffusion of the winterizing product.

The pool pump and pool cleaning

It is also thanks to the filtration pump that cleaning the pool is possible, when using a vacuum cleaner or a hydraulic robot. It is also essential for cleaning the filter.


The filtration pump is essential equipment, without which the swimming pool cannot function. This is the heart of the technical room. It must best match the characteristics of the pool and the filtration method for maximum efficiency. Now that we know its usefulness, it is time to look at its characteristics.



Now that we know its usefulness, it is time to look at the characteristics of a swimming pool filtration pump. Also learn what elements make up the swimming pool filtration pump to more easily understand how the swimming pool filtration pump works. Finally, discover what is a variable speed swimming pool filtration pump and what are the advantages of the variable speed swimming pool filtration pump to help you choose the pump best suited to your pond.
