How to Choose A Good Water Pump for Swimming Pools?

Choosing a water pump for swimming pools is not an easy task because there are many factors involved in this decision. It is very important that the pump purchased is adequate since otherwise, it could lead to a malfunction of the pool.

You should know that the water pump is not only used for swimming pools. There are different pump options for what elements. An example of this would be the boilers, which need a circulating pump to move the water.

What Is A Water Pump?

A water pump for swimming pools is an engine that moves the water of the pool, taking it from the pool itself to the treatment plant and returning it back to it. In the purification of the pool, the water will pass through a series of filters that will clean the water and thanks to the pump, the water will return to the pool.

As you can see, the water pump is an essential element, because, without it, the water would not leak and would be unsuitable for the bath. The water in the pool passes through two filters: a first filter called a pre-filter, which prevents larger elements, such as leaves, from entering the interior of the treatment plant. This pre-filter is similar to a grid and we must make sure it is not blocked for a long period of time.

Once the water passes through the first filter, it is introduced into the second. This is responsible for filtering all the particles that may contain water. The operation is very simple: water circulates through a filter composed of sand or glass that is responsible for trapping all the dirt in the water.

To maintain the correct functioning of all the pool products that are involved in the purification process, you should clean the prefilter frequently. Otherwise, the water could not be moved by the pump due to a collapse that could deteriorate the other elements that influence the process, including the pool pump.

It is important to note that the movement made by the pool pump must be very slow. If in the filtering process the water circulates under pressure, the particles and other objects that are in the water would not be filtered and would return to the pool.

How To Choose A Water Pump For Swimming Pools

Not all pools are the same size or all are given the same use, so you must ensure that the water pump for pools you acquire is appropriate for the use you make of your pool.

If you want to know what are the factors that influence when choosing a water pump for swimming pools, do not miss the list that appears below.

#1 Power

To know what power our water pump for swimming pools should have, the first step is to measure the size of the pool. This will not be measured by its capacity but by its length: we must measure the length, width, and depth and multiply the results.


In the same way that not all pool water treatment plants are the same, the pumps will not be the same either. A swimming pool in a patio of a house will not measure like an Olympic pool, but both need a pump that moves the water, although obviously, they will not need the same power.

#2 Flow

To choose the right water pump for swimming pools, it is necessary to take into account the amount of water we want to move per unit of time. Normally, the purification process takes place between four and eight hours a day, depending on the size of the pool.

#3 Energy Sources

The water pump needs to be connected to electricity. We must choose a water pump that fits the power that has the power: in a house, there will be less power than in a sports center.

There are other types of water pumps such as solar water pumps, which are used for agricultural irrigation but are not suitable for swimming pools. The most common for this case are the electric ones.

#4 Filter diameter

Good water pump for swimming pools should be ideal for the size of the filter. Otherwise, we would have a leak in the purification process. You must know the measurements of your filter when you are going to choose your water pump for swimming pools.

#5 Filter capacity

The capacity of the filter influences the choice of the water pump for swimming pools because if we do not choose a pump whose power is commensurate with the capacity of the filter, the latter could be damaged.

If the water is pumped with a lot of pressure, its passage through the filter would be very fast and the sand found in it would be deteriorated, thus preventing it from developing its filtering function.
