What elements make up the swimming pool filtration pump

What are the different parts of the swimming pool filtration pump?

Essential to the quality of swimming pool filtration, knowing what is a swimming pool filtration pump is essential to fully understand this equipment. Each element is part of the cog of the machine and has a role to play in its functioning.

The motor of the swimming pool filtration pump

The body of the pump contains the motor which ensures the operation of the filtration. It is made up of a turbine which helps to set in motion the circulation of water in the pipes and the swimming pool, an axis, ball bearings, a box which encloses the capacitor and the electrical wiring , a fan…

The pump has two orifices: the suction, a water inlet on the side of the pre-filter and a discharge, a water outlet which is located on the top of the device and which directs the liquid towards the pool filter.

On the body of the pump, a drain plug allows emptying during wintering in particular.

The materials and techniques used for its manufacture have an impact on its resistance to wear and have an influence on the environment and energy and financial savings.

The pre-filter of the swimming pool filtration pump

The filtration pump is, in the majority of cases, equipped with a pre-filter. The pre-filter is responsible for pre-cleaning the water that arrives directly from the pool. The basket retains up to 70% of impurities. The largest particles, such as leaves, twigs, etc. remain blocked, but also the smallest, those between 50 and 80 microns, grass for example.

Be careful, if the pre-filter is too full, the pump strains and there is a loss of power and therefore performance.

Thanks to it, cleaning of the sand filter, cartridge filter, etc. is spaced out. This results in water savings (good for the wallet and the environment), time savings and greater longevity for cartridges in particular.

The transparent cover allows you to see the water movements and ensure that the water circulation is carried out correctly.

When the pre-filter is clogged with debris, simply unscrew the cover to empty the basket. Care must be taken to cut off the power supply and the water supply before the intervention. Avoid hitting the basket on the floor to get rid of the dirt adhering to the wall, otherwise it could break!

The fan

The fan is a small part that should not be neglected. It is located opposite the pre-filter, protected by a grille and has the function of cooling the engine.

For the fan to properly perform its function, the space around it must be clear so that the air circulates freely. This element requires little maintenance, dusting the blades using a soft, lint-free cloth (microfiber). Do not turn the fan in the opposite direction to its rotation and do not twist the blades.


The swimming pool filtration pump is an essential piece of equipment in the filtration system. It is robust and requires little maintenance. Knowing the different elements that constitute it allows you to better identify possible malfunctions.



Knowing what is the role of the swimming pool filtration pump will help you understand the importance of this device for your swimming pool installation. Also learn what are the characteristics of a swimming pool filtration pump to better 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.
