The characteristics of a swimming pool filtration pump

What are the general characteristics of a swimming pool filtration pump?

The filtration pump is a vital element for the proper functioning of the swimming pool. Without it, no water circulation. For optimal operation of the aquatic pool, it is essential to know what is a filtration pump swimming pool and to know the technical criteria which characterize it because there are many models. So how do you find the one that best suits your pool? What are the main features that should attract your attention?

The essential data of a swimming pool filtration pump

Many distinctions are offered and differentiate the swimming pool filtration pump. Four are essential: its power, its flow rate, its power supply and its compatibility with water treatment.

The power and flow rate of the swimming pool filtration pump

The power and flow rate of the filtration pump are the first concepts to take into account. They must be in line with the volume of the pool but also with the other equipment in the pool, in particular with the filter which is its inseparable "partner", the automatic treatment, the heat pump, etc.

The power of the pump will vary depending on the flow rate, itself under the influence of pressure losses. The performance curve allows a clear view of the pump power as a function of flow rate. Each pump has its own curve that must be present in the device instructions.

The power supply for the swimming pool filtration pump

Generally, the swimming pool filtration pump is single-phase, but many models are offered in three-phase. It must, of course, be compatible with the electrical installation on which the technical room depends. It is subject to a protection index relating to its waterproof level (IPX 5, IPX4, IP55, IP44, etc.).

Compatibility of the swimming pool filtration pump with water treatment

All swimming pool filtration pumps are compatible with treatment with chlorine, bromine, active oxygen, etc. One exception however, salt electrolysis requires a specific swimming pool pump compatible with this treatment.

If the treatment chosen is PHBM, the pump closing cover must not be made of polycarbonate.

Take into account the specificities of the swimming pool filtration pump

For filtration pumps, also called circulation pumps, there is an abundance of special features. Technical developments allow easier maintenance, better resistance of the device or more energy-efficient equipment.

To facilitate maintenance: the pre-filter

The pump pre-filter is fitted with a basket which retains the largest impurities, preventing them from blocking the pump or clogging the filter too quickly. It is essential if the vegetation is close to the swimming pool. A large, high-capacity pre-filter minimizes maintenance, but the pump is larger.

The transparent cover allows you to view the cleanliness of the pre-filter. It is equipped with an O-ring which allows sealing.

Some pumps do not have a pre-filter, in which case the smaller pump takes up less space. It is ideal for a buried technical room or a filtration block.

Technical developments

The self-priming circulation pump is equipped with a mechanical device which detects the arrival of water in the pre-filter and allows automatic start of the pump. Starting the pump is simplified and reliable. If the technical room is below the level of the swimming pool water line, due to the effect of gravity, the pump is permanently charged. For other positions of the filtration pump in relation to the water level, self-priming prevents the pump from running empty and overheating.

The single-speed pump always maintains the same power whatever the climatic situation or the use of the pool. The variable speed pump adapts its power according to the need and use of the pool. The power is higher when there is high use of the pool or when the hydraulic robot is operating. If the pool and filter are clean or if no one is swimming, the pump runs at low speed. The variations are controlled manually, by a programmer.

Swimming pool filtration pumps can be controlled remotely from a smartphone via an application, Wi-Fi or a suitable box.

Swimming pool filtration pumps are reliable and their lifespan varies between 8 and 10 years. But it must be chosen according to the use and characteristics of the pool. Other particularities may come into play, such as the operating temperature.

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 elements make up the 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.
