The water pump – the device which is necessary for the correct work of the pool. Pump designs help to prepare the pool for the winter period, heat water, purify it, chlorinate and perform many other functions.
Types of pumps
Designs which pump out water are applied to several purposes at once: water cleaning, elimination of microbes and seaweed, etc. Depending on function there are different types the technician:
- the filtering pumps;
- circulating pumps;
- the counteracting pumps;
- designs for creation of hydromassage systems;
- submersible systems;
Each look has the advantages and shortcomings. To be defined what pump it is better to choose, it is necessary to sort features of each model.
The filtering pumps
Filtration of water has to be obligatory. If not to carry out it, then on surface there will be greenish raid, seaweed, bacteria will breed. The pool will become more similar to normal pond, and will clean it hard constantly from silt and other pollution.
This type of the pump incorporates water and passes it via the filter of sand or paper type, and then all cleaned volume under pressure releases back in reservoir. Such installation is suitable only for cleaning from mechanical pollution. If it is necessary to eliminate microbes and bacteria, it is necessary to install in addition the equipment - ozonizer. And if such purchase is too heavy for the budget, it is possible to use chemicals or chlorine, but not pump cleaner.
Circulating pumps
These installations provide continuous updating of water currents. Thanks to them from water large particles are removed, the risk of formation of seaweed decreases. At the same time water looks clear and evenly gets warm, and pumping out happens almost silently.
Types of devices:
- vortex;
Centrifugal quicker also stand less, but can take away water only in one direction and have to be used in small reservoirs. Vortex differ in more difficult device, the raised price. They can take away water in several directions at once, but at the same time more noisy. If the inexpensive device with silent work is necessary, it is better to take centrifugal type.
The counteracting and hydromassage devices
The counteracting pumps pump up water and produce it under big pressure to create current, fountain or falls. This decorative device.
Hydromassage pumps a little in what differ from counteracting, such installations also are based on the counteracting system. Water is pumped out from the pool too and is given back in basin reservoir under pressure, only from above on the pump the hydromassage nozzle is established.
Submersible systems
Submersible pumps fall to the pool and extort from it water. Household installations can remove water up to 5-10 cm from reservoir bottom, pumping is carried out in several hours. And more professional leave only 1 cm, but such installations are necessary to generally public pools.
Such devices are used time during season to clean the pool for the winter or during scheduled maintenance for cleaning. If it is necessary to change all water, to completely clean bottom or walls, resort to the help of submersible systems. The filter used earlier is removed: when pumping water it is not necessary to sift dirt, the design is on the contrary calculated on reception of particles by the size even in 5 cm, passes various garbage.
Thermal designs
In heat pumps there is special gel. It absorbs warmly from the outside and with its help heats water which carries out the movement through it. The equipment works as well as for the fridge, only in the opposite direction – there is not cooling, but heating.
Heating is necessary for the closed demi-season pools or open summer.
How to choose the pump
The unit needs to be chosen proceeding from the volume of the pool and functions which the device has to carry out. Let's sort what models for what are suitable:
- the heat pump – is good for indoor pools, but badly copes with pollution. Well copes with heating function;
- submersible – is used for pumping out of water at pool work stoppage, but it is impossible to apply more often than once a week;
- filtering – can be established together with circulating or to get model 2v1, it is necessary for pools of any sizes;
- circulating – one more obligatory attribute of the pool which needs to be selected according to water volume (the exact size of reservoir is measured);
- counteracting – is used for hydromassage, creation of waves and falls therefore it is applied only to expensive pools.
It is also necessary to calculate precisely pool volume to choose model. On sanitary standards at least 4 volumes of the pool have to pass per day the pump of circulating type through themselves. But for frame and inflatable pools this indicator is slightly more – quarter of volume in hour or 6 volumes of the pool per day. At the same time all water has to be updated, that is it is necessary to mount installation so that its pressure and the inhausting elements covered all width or length of reservoir. Normal pumps of the budgetary models possess pressure in 10 meters if it is self-inhausting – it is slightly less. It is enough even for the biggest combined reservoir.
Clearing filters for the pool
It is impossible to forget also about water cleaning. For this purpose there is two filter: sand and paper.
Features of paper:
- weighs less;
- it is easily replaced;
- only a month serves therefore it should be changed often;
- purifies water from small particles, but can pass nanoparticles.
Such option is suitable for pools which use not too often. If in family more than 6 people and they daily use reservoir, it is better to buy more powerful device. It is worth thinking of acquisition of the sand filter and in case the pool is located not under canopy, and various particles often get to it.
Features of the sand filter:
- weighs much;
- does not pass even nanoparticle;
- it is necessary to make replacement of contents time in 2-4 years.
At the sand filter more flow capacity. This product for large pools and for buyers with the big budget.
The most popular pumps
Pump designs can be got complete with the pool. It is the most popular option: frame or inflatable systems are often already completed with the device calculated just on the necessary volume of water. Bestway and Intex belong to the companies which sell the completed sets. Their overview is given below.
- Intex – the Chinese brand. This is the leader in the market of the equipment connected with small home pools. The organization makes frame and inflatable pools, filters, pumps, chlorogenerators and cartridges for paper filters. Models of this firm are intended for pumping about 5600 liters of water an hour. They work at standard power supply with tension of 220 W, differ in small weight. Filters which are built in the pump at once contain either sand, or paper. More often – paper. Thanks to the small volume of the filter it is easy to establish or transfer it, unlike professional models. This brand offers pumps of small and average power and also chlorogenerators which produce chlorine from normal table salt. Chlorine kills microbes, seaweed, purifies water from greenish shade and typical smell of natural reservoir. In hour about 11 grams of chlorine which, unlike chemicals for the pool, is completely safe are produced.
- The Bestway company selling inflatable and frame pools uses services of the Korean engineering organization Emaux. These producers create the designs reminding on exterior and system performance from Intex. Maximum capacity – 13000 liters an hour. Sand filters are not used, used only paper cartridges. It is possible to replace them once a month, and here in Inteksa it is necessary for thicket – 2-3 times a week.
It is difficult to choose between these two brands. The decision needs to be based on that what pool of the producer you will get.
If you need more professional pumps which can create circulation for pools even of public use, then it is necessary to address the German, Spanish and other European brands:
- Behncke – the German producer. Models of this firm work from voltage of 380 V, miss 32,000 liters of water for hour. Pumps are installed on the platform which allows to move the device easily.
- Kripsol – the Spanish firm. Makes both small devices with paper cartridges, and large sand installations. The biggest pump weighs more than 100 kg, is filled with glass sand with frequency change in 3-4 years, works from tension in 380 V. Kripsol misses 30 thousand liters of water for hour.
It is better to carry out purchase of the pump after consultation with the seller in specialized shop. To find in the next availability shops quite difficult, and to here pick up suitable online store much more simply. In it it is possible to order consultation on phone which will never be superfluous. The consultant will pick up the optimum power of the device and type of cleaning for your individual parameters, will carry out the comparative analysis of models.
