Why in the pool pump?

A pump is a device for pumping fluid. The number of pumping devices in the pool depends on the complexity of the entire pond system and the volume of water.

The number is also influenced by the presence of special zones: spa, hydromassage, fountains, sports, attraction sites.

Several types of pumps are involved in maintaining and ensuring the normal operation of the pool:

  • Pump for pumping water. Required to fill an artificial reservoir, for emptying the tank in case of repair, sanitary care, preservation for the winter.
  • Circulation pump. Providing the movement of water to the cleaning and heating units and back.
  • Heat pump. It is used in the case of an alternative system for obtaining thermal energy instead of the traditional heating option.
  • Backflow pump. Used in the organization of hydromassage, 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 choice 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 casing is shaped like a snail.

Pool layout

If you decide to pool more than a child, you can not do without a pump

With the rapid rotation of the impeller, the water is keen on the blades and squeezed to the walls.

As a result, two phenomena occur simultaneously:

  1. A vacuum is created in the center, as in a funnel.
  2. Water moving along the increasing radius of the cochlea of ​​the body picks up speed and is pushed out.

For centrifugal pumps are characterized by: low pressure, not high 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 force the air through.

Diagram of the device centrifugal pump

Centrifugal pumping systems are used to fill and empty the pool, serve as auxiliary equipment in case of insufficient capacity of the circulation pump. In the diagram, the intake water is shown by blue arrows.

The vortex pumps have a special impeller design, called impeller. The case of the vortex pump tightly enough embraces the impeller in diameter, but has a gap from the sides.

When the impeller is moving, the flow of water in the form of vortexes is twisting 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 capable of starting suction with a small amount of water or without it at all; therefore, they do not require mandatory filling of the pipe before starting work.

Vortex Pump Diagram

The diagram shows the components of the pump vortex type. Due to the specifics of its performance, its efficiency cannot exceed 60%.

For vortex pumps are characterized by: high pressure at the outlet, increased noise of work, a small volume of pumped water.

Both types of pumps without accessories cannot create a vacuum of more than 1 atmosphere, therefore they are limited to a pressure of 10 m, which is quite enough to maintain the pools.

View # 2 - self-priming pumps

Self-priming pumps are the most common, as they allow you to install them above or below the water level. This is especially true for frame and inflatable pools, when it is not possible to place equipment under the pool.

Self-priming pump capable of producing water from three meters in height. However, it should be borne in mind that the rise of water requires considerable energy, so the pump should be installed as low as possible.

When choosing a pump should be considered:

  • The bandwidth of the filter elements. It should correspond to the performance of the pump.
  • The diameter of the suction and discharge port.
  • The volume of pumped water complying with sanitary standards.
  • The possibility of long work.
  • Noise level.
  • The material of manufacture.

When choosing self-priming pump It is necessary to pay attention to the ease of maintenance of the unit. Existence of a viewing window, helps to define filling of the filter.

The cases of self-priming pumps are made of reinforced plastic, the shaft and fasteners are made of stainless steel.

Self-priming swimming pool pumps

Self-priming pumps are characterized by the ability to independently draw in water from a depth. Modifications for swimming pools are equipped with IP54 protection level, which allows working in rooms with high humidity

View # 3 - filter element pump

Pumps with a filter element are most often used for ready-made pools: frame or inflatable. Such devices are completed by the manufacturer with the appropriate filter.

The simplest water treatment systems can do with only one pump of this type.

Filter elements are of several types:

  • sand pumps;
  • paper cartridges.

Pumps with paper cartridges It is advisable to use for small pools. Paper filters effectively purify water, but cannot provide a large amount of water.

In addition, they often have to change, which is bad for the cost of maintenance.

Pumps with sand filter or sand pumps, more efficient and designed for large volumes of water. Water is passed through quartz sand and all the dirt, even the smallest particles are deposited in the sand.

To clean the sand filter, water is passed in the opposite direction and drained into the sewer.

Other adsorbents can be used instead of quartz sand: glass sand, gravel, anthracite, carbon. Carbon based filters are the most effective.

When choosing a filtering adsorbent, pay attention to the duration of work. For example, quartz sand should 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 disintegrate.

The disadvantage of pumps with a filter element is that the two filter devices and the pump are mounted in the same housing. When you exit the standing of one of the devices, you will have to buy both.

Pool equipment complex

For normal operation, the pool needs a complex of pumping equipment in which each unit performs its work.

View # 4 - circulation units

Circulation pump - 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 circulating pump should have such a capacity that it can pump at least 4 times the entire volume of pool water within a day.

As for inflatable or frame pools with one pump, its capacity should be about ¼ of the pool per hour.

Pump with prefilter

The prefilter of pumps consists of a lattice basket. To control the filling level, a viewing window is made on top.

The circulation device used in the arrangement of the pool differs from other types of pumps in two ways:

  1. The presence of the filter element. It does not allow large debris to jam the pump impeller.
  2. Housing material. The resistance of the materials of the body and the technical filling of the pump to corrosion and destructive oxidation occurring due to the use of disinfecting chemicals.

According to the criteria of pressure, the circulation pump should be selected depending on the degree of complexity of the pool to be installed.

A low-pressure machine is enough if only the movement of water in the tank is planned for the distribution of antiseptics and the direction of 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 the water from the pool, you can do circulating 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 using self-priming pumps to drain water more than 1 time per week.

Specialized pumps for pumping water are made submersible. They have wide intake windows and are able to pump out contaminated water with particles up to 5 cm.

The system has an automatic shut-off system in the absence of water. Capable of pumping water up to 1 cm or less.

Household drainage pumps universal application usually have a float that turns off the pump when the water level is 5-10 cm below the height of the pump. They can not completely pump out the water.

Pump for pumping water

Submersible drainage pump for pumping water from the pool is equipped with a vertical outlet. And you can choose a model that can cope with pumping not only clean, but also very dirty water.

View # 6 - Modification of pumps 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 prefilter are used as an addition to an existing system. As an additional circulation pump or for organizing special zones in the pool.

Heat pumps for pools

In most of our country, summer is coming to an end very quickly. During the night or on cloudy days, the pool water cools down. Traditional heaters heat the pool expensive.

The principle of operation of the heat pump

Principle of operation heat pump can be clearly seen on the example of a domestic refrigerator. The composition of the heat pump includes: heat exchanger, compressor, evaporator.

Freon is circulated in the heat pump system, a gas capable of becoming liquid at room temperature. At the transition of the phase state of freon, heat is taken from the environment and further heating of the circulating water in the heat exchanger.

In short, the refrigerator is the opposite: the environment is cooled, the water is heated.

In terms of interaction with the environment, there are three types of heat pumps: ground-water, water-water, air-water.

Heat pumps for the arrangement of suburban pools

Heat pumps used for arranging swimming pools not only heat the water, but also maintain its stable temperature.

Heat Pump Selection Criteria

Each type of pump has its own rules for mounting the circuit. For ground-water pumps, horizontal or vertical pipe installation is required.

In any case, pipes should be laid at a depth of at least 2-3 meters - to a depth of frost penetration. From above you can not plant trees with a strong root system.

Heat pump in the pool

Heat pumps for pool arrangement are used if there are no free capacities for heating the water in the tank to a comfortable temperature.

The air-to-water circuit warms the pool water

In the arrangement of the pools, air-water systems are mainly used, which take away the energy of the air to heat the water.

Installation of air-water near the pool

Air-to-water heat systems do not require the construction of equipped wells or large areas for the receiver device

Heat pump requires very little energy

The equipment consumes a minimum of electricity. At a flow rate of 0.95 kW, the heat pump delivers 5.5 kW, which is much more than the output of electrical equipment

Heat pump requires very little energy

Water-to-water pumps use the energy of water bodies. Such pumps are a profitable option, as they do not require excavation of the previous type of pumps.

In these systems, it also requires laying to a depth of freezing of 2-3 meters. The distance from the reservoir to the pool should not be more than 100 meters.

Air-to-water systems do not require complex piping and are easy to install. But, air-water pumps less effective because they extract the thermal energy of the air and depend on its temperature in a specific time period.

When choosing an air-to-water heat pump, consider:

  • pump installation site (sun or shade);
  • average air temperature;
  • pool volume;
  • pool type (outdoor or indoor).

Regardless of the heat pump system chosen, an average of about 5-8 kW of heat energy is generated per 1 kW of electricity consumed. Modern heat pump systems can even heat an outdoor pool all year round.
