How to choose a pump for the pool: the rules of selection and classification

And when we went to the cottage pool, you need to remember that the water you love to splash around not only people. It’s a great environment for germs, algae for mosquito breeding. And not to let them there is only one way: continuous filtration and purification of water. Of course, inflatable baby pools do not require additional equipment. Being easier every day to pour the water on the garden, rinse the case and fill with fresh fluid. But the bigger the bowl, the harder it is to maintain. Tons of water daily and even weekly change no one will, because we still have to figure out where to put them. Therefore, primary care «is placed on the shoulders» filtration system which is the pump for the pool. Without clean and safe water facilities, you will not achieve.

How many pumps you need to use?

The number of pumps depends on the design of the basin and its capacity. As a rule, to inflatable and frame construction with large volume bowls manufacturers are making one filter pump for swimming pool.

Scheme of water movement

The pump pumps the water through the purification system and heating, so its power should be enough for a complete turnover of liquids within 6 hours

Stationary vessels that are used frequently or year-round, require multiple pumps. The main unit is responsible for filtering, one creates a counter-current, and the third launches the installation of ultraviolet, the fourth includes fountains etc in the pool of relaxation areas, such as a Jacuzzi, massage jets, more pumps involves. Here’s what the experts say on the matter:

Classification of water pumps

All pumps for pools can be divided into 4 groups:

  • self-priming;
  • circulation pumps with normal suction;
  • filter;
  • thermal — for heating.

Self-priming pump – the heart of the water system of the pool

These pumps are installed above the swimming pool, because they can pump water and to raise it to a height of about 3 meters. The main function is to provide water filtration. Typically, the pump is included filter equipment, because the capacity mechanism and the filter mechanism should be the same. If the pump will be «stronger», it will be too fast «to drive» water into the filter, forcing it to work overtime. The cleaning quality will drop, and the filter element will quickly fail.

Self-priming pump

The main pool pump is responsible for the quality of filter, so try to trim its capacity by the volume of the bowl

Self-priming pump moves the water in a circle: dirty it sends to the skimmer and then into the filter. And already purified liquid returns to the Cup. In the unit also has a filter, but it carries out only pre-treatment without missing major items like toys, bottles, etc..

The scheme of work of the pump

A centrifugal pump connected with the entire filtration system of the pool

With constant use the home pool is usually set and a spare pump which will launch in case of a failure of the main. It is not recommended to place a backup mechanism in the same line as the main, as it may cause high flow resistance. The best option is to record in parallel with the main unit. However, this method is rather laborious, because to provide for this possibility had already at the stage of construction of the bowl. But run it when you disable the main system is a very short time.

For the main pumps do not accidentally devised a system of self-suction. It reduces the likelihood of clogging and simplifies the operation of the unit.

Important! Although the instructions for self-priming pump indicates that it is able to function above the water level, but the higher you raise the system, the more it will have to expend energy to lift the liquid. Overload is unprofitable neither pump nor you, so it is recommended in closed basins to put it in the basement.

If the building is located in the fresh air, then, of course, the basement for him there. In this case, you can hide the pumps for pools in special containers from thermoplastic. There and put the rest of the equipment (transformer, control unit, etc.). Such containers are available in two versions: submersible (they are hidden under the lawn, keeping the upstairs free access to the cover), or semi-submersible (hiding in the ground is not full). The first option is convenient because does not occupy space and does not affect the landscape. The second is easier to maintain.

Water pumps for pools not in use steel. It is too subject to corrosion under the influence of chemically active disinfectants (chlorine, active oxygen, etc.). The steel body and mechanisms is only allowed in structures where the water is not treated by any means, and cleaned with ultraviolet installations. In the other pools put the pumps of high-strength plastic or bronze. They no reagents are not affected. However, if your intention is to create a pool with salt water (and it happens!), that plastic is not suitable because it will be delayed salt. There’s only one option – bronze.

Circulation pump with a normal suction

To help the main pump is getting simpler units that perform the local tasks to bring about the movement of water in a particular place pool, for example, to create a fountain, the bubbles in the Jacuzzi, etc. For saturation of water with ozone is necessary part of her absorbed into the ozonator, and then, enriched, to produce back. This too performs circulation pump for swimming pool.

Non-self-priming pump

Pumps with normal suction circulate water and fountains, Jacuzzi, slides

To find such units is to be based «bloat» the design of the pool. To create counter current and water circulation that helps uniform distribution of chemical disinfectants throughout the bowl, enough to buy a low pressure pump. If well conceived system of water attractions – slides, fountains, etc., you need a high-pressure model with a capacity of more than 2kW.

Pump filter: for mobile portable swimming pools

When buying a frame or inflatable models summer resident in the set receives and pump to clean the pool. It simultaneously performs the function of a pump and filter, cleansing the water of debris. Such systems are designed for several summer seasons or about 2 thousand hours of work. Require systematic cleaning and replacement of filter elements. Remember that pumps and filters are able to remove only suspended particles, not had time to settle to the bottom. So, it is necessary to choose pump performance that matches the volume of the bowl. If power will be enough — the dirt has time to settle to the bottom and you will need to drain all water to remove it.

Pump filter

Filter pumps are used in swimming pools seasonal use, as they have a lifespan of about 3 seasons

Pumps heated: extend the swimming season

Owners wishing to use the outdoor pool almost to the winter, you will need a heat pumps for pools. These units heat the water with the indoor unit, drop directly into the bowl. The outdoor unit stays on top and can work with air conditioning or a heater of the air in the pools closed. This method of heating is cheaper than gas heating, about 5 p. besides, heat pump for pool has a long life – over 20 years, which is important for stable functioning of water facilities.

Heat pump

Heat pumps can heat water up to 40 degrees

Pump for swimming pool – as the heart to the body. From the smooth operation will depend on the safety of water, and hence the health of the hosts.
