To make it easier for you to choose your version of the pump, we have selected videos that clearly demonstrate the capabilities of the considered units, and photos. Many of the models are able to solve various problems, helping to turn the pool into a remarkably equipped artificial pond for a pleasant rural vacation.
What is the pump in the pool for?
A pump is a device for pumping liquids. The number of pumping devices in the pool depends on the complexity of the entire pond system and the volume of water.
The abundance is also affected by the presence of special zones: spa, hydromassage, fountains, sports, and attraction areas.
Several types of pumps are involved in the maintenance and normal operation of the pool:
- Pump for pumping water. It is required to fill an artificial reservoir, to empty the tank in case of repair, sanitary care, conservation for the winter.
- Circulation pump. Providing movement of water to cleaning and heating units and vice versa.
- Heat pump. It is used in the case of an alternative thermal energy production system instead of the traditional heating option.
- Counterflow pump. It is used in the organization of hydromassages, water rides, waterfalls and similar special effects.
All these pumps have their own specifics. The purpose of the further review is to show the diversity and principles of the selection of pumping equipment for the water world of pools.

Types of pumping equipment for the pool
Pumps traditionally used to service pools without specific functions can be divided according to the principle of operation into centrifugal and vortex.
View # 1 - centrifugal and vortex aggregates
In centrifugal pumps, the impeller is a disk with curved blades. Moreover, the blades are bent in the opposite direction of rotation. The pump housing has the shape of a snail.
If you decide to have a pool more than children’s, you can’t do without a pump
With the rapid rotation of the impeller, water is carried away by the blades and squeezed to the walls.
As a result, two phenomena occur at once:
- A rarefaction is created in the center, as in a funnel.
- Water moving along the increasing radius of the cochlea shell picks up speed and is pushed out.
Centrifugal pumps are characterized by: low pressure, low noise, large volume of pumped water.
To operate the pump, it is necessary to fill the inlet pipe and the impeller housing with water, since such a system will not push air.
Centrifugal pump systems are used to fill and empty the pool bowl, serve as auxiliary equipment in case of insufficient circulation pump power. In the diagram, the intake water is shown by blue arrows.
Vortex pumps have a special impeller design called an impeller. The body of the vortex pump grabs the impeller quite tightly in diameter, but has a gap on the sides.
When the impeller moves, the flow of water in the form of vortices swirls on the blades, hence the name.
Due to the small gap, the vortex pump is able to work on a mixture of air and water. Vortex pumps are able to start suction with a small amount of water or without it at all, therefore they do not require filling the pipe before starting work.
The diagram shows the components of a vortex type pump. Due to the specifics of its efficiency, it cannot exceed 60%
Vortex pumps are characterized by: high pressure at the outlet, increased operation noise, small volume of pumped water.
Both types of pumps without additional devices cannot create a vacuum of more than 1 atmosphere, therefore they are limited by a pressure of 10 m, which is quite enough to service the pools.
View # 2 - self-priming pumps
Self-priming pumps are the most common, as they allow you to install them above or below water level. This is especially true for frame and inflatable pools, when it is not possible to place equipment under the pool.
The self-priming pump is capable of taking water from three meters high. However, it should be borne in mind that raising water requires significant energy, so the pump should be installed as low as possible.
When choosing a pump, you must consider:
- The capacity of the filter elements. It should match pump performance.
- Diameter of suction and discharge nozzle.
- The volume of pumped water complies with sanitary standards.
- The possibility of continuous operation.
- Noise level.
- The material of manufacture.
When choosing a self-priming pump, you must pay attention to the ease of maintenance of the unit. The presence of a viewing window helps to determine the filling of the filter.
Cases of self-priming pumps are made of reinforced plastic, the shaft and fasteners are made of stainless steel.
Self-priming pumps are characterized by the ability to independently draw water from a depth. Modifications for pools are equipped with a degree of protection IP54, allowing operation in rooms with high humidity
View # 3 - pump with filter element
Pumps with a filter element are most often used for finished pools: frame or inflatable. Such devices are equipped with an appropriate filter by the manufacturer.
The simplest water treatment systems can do with just one pump of this type.
Filter elements are of several types:
- sand pumps;
- paper cartridges.
Pumps with paper cartridges suitable for small pools. Paper filters effectively purify water, but cannot provide a large volume of water.
In addition, they often have to be changed, which adversely affects the cost of maintenance.
Pumps with sand filter or sand pumps, more efficient and designed for large volumes of water. Water passes through quartz sand and all the dirt, even the smallest particles settle in the sand.
To clean the sand filter, water is passed in the opposite direction and drained into the sewer.
Instead of quartz sand, other adsorbents can be used: glass sand, gravel, anthracite, carbon. Carbon filters are the most efficient.
When choosing a filter adsorbent, pay attention to the duration of work. For example, quartz sand needs to be changed once every three years, and glass sand once every five years.
Additionally, ozonizers are installed on sand pumps.Ozonizers kill microorganisms and oxidize small particles of dirt, causing them to decay.
The disadvantage of pumps with a filter element is that the two filter devices and the pump are mounted in one housing. When exiting from a standing one of the devices, you will have to buy both.
For normal operation, the pool needs a complex of pumping equipment in which each unit performs its work
View # 4 - circulating units
The circulation pump is one of the main units necessary for the normal functioning of the pool.
The simplest artificial reservoir can cost one pump of this type. He is responsible for creating a constant flow of fluid through the filter elements.
According to the sanitary standard, the circulation pump must have such a capacity to pump at least 4 times the entire volume of pool water per day.
As for inflatable or frame pools with one pump, its performance should be about ¼ of the pool volume per hour.
The pump prefilter consists of a trellis basket. To control the fill level, a viewing window is made from above.
The circulation device used in the arrangement of the pool differs from other types of pumps in two ways:
- The presence of a filter element. It prevents large debris from jamming the impeller of the pump.
- Case Material. Resistance of casing materials and technical filling of the pump to corrosion and destructive oxidation due to the use of disinfectant chemicals.
The circulation pump according to the pressure criteria should be selected depending on the degree of complexity of the equipped pool.
A low-pressure machine is enough if it is only planned to move water in a container to distribute antiseptics and direct flows to the filters. Those wishing to organize their own water park should be interested in models with high pressure values.
View # 5 - submersible models for pumping water
To pump out water from the pool, you can do with a circulation self-priming pump. It should be borne in mind that self-priming pumps for inflatable and frame pools are not designed for continuous operation.
Manufacturers do not recommend the use of self-priming pumps to drain the water more than 1 time per week.
Specialized pumps for pumping water are submersible. They have wide intake windows and are able to pump out contaminated water with particles up to 5 cm.
The pumps have a built-in automatic shutdown system in the absence of water. Able to pump water up to 1 cm or less.
Universal drainage pumps for universal use usually have a float shutting off the pump when the water level is 5-10 cm below the height of the pump. They cannot completely pump out water.
Submersible drainage pump for pumping water from the pool is equipped with a vertical outlet. Moreover, you can choose a model that can cope with the pumping of not only clean, but also very dirty water
View # 6 - pump modifications without prefilters
Pumps without prefilters are used for large and stationary pools. Characterized by high power and performance.
Such pumps are used for:
- circulation;
- hydromassage;
- waterfall;
- fountain;
- SPA
Pumps without a prefilter are used as an addition to an existing system. As an additional circulation pump or for organizing special zones in the pool.

Pool heat pumps
In most of our country, summer is coming to an end very quickly. During the night or in cloudy weather, the water in the pool cools. Traditional heaters to heat the pool is expensive.
The principle of operation of the heat pump
The principle of the heat pump can be clearly seen on the example of a domestic refrigerator. The heat pump includes: heat exchanger, compressor, evaporator.
Freon circulates in the heat pump system, a gas capable of passing into a liquid state at room temperature. When the phase state of Freon passes, heat is taken from the environment and then the circulating water in the heat exchanger is heated.
In short, the refrigerator is the other way around: the environment is cooled, the water is heated.
According to the interaction with the environment, there are three types of heat pumps: soil-water, water-water, air-water.
Heat pumps used for arranging pools not only heat water, but also maintain its stable temperature
Heat pump selection criteria
Each type of pump has its own installation rules for the circuit. For ground-water pumps, horizontal or vertical pipes are required.
In any case, pipes must be laid at a depth of at least 2-3 meters - to the freezing depth. From above it is impossible to plant trees with a powerful root system.

Pool heat pump
Air-to-water circuit heats the pool water
Installation of air-water near the pool
The heat pump requires very little energy
Water-to-water pumps use the energy of water bodies. Such pumps are a profitable option, since they do not require excavation of the previous type of pumps.
In these systems, laying to a depth of freezing of 2-3 meters is also required. The distance from the reservoir to the pool should not be more than 100 meters.
Air-water systems do not require complicated piping and are easy to install. However, air-water pumps are less efficient, since they extract the thermal energy of air and depend on its temperature in a specific time period.
When choosing an air-water heat pump, consider:
- pump installation location (sun or shadow);
- average air temperature;
- pool volume;
- type of pool (outdoor or indoor).
Regardless of the heat pump system selected, approximately 5-8 kW of heat energy is generated per 1 kW of consumed electricity. Modern heat pump systems can even heat an outdoor pool year-round.
