How to choose a pool pump: a comparative overview of different types of units

Types of pumps

All pumps used in everyday life can be divided into two groups: surface and submersible.

Surface pumps are placed at the edge of a water tank or reservoir. They can be used both for drainage and for pressurizing the pipeline.

Submersible pumps, as the name implies, sink directly into the water. They are used for water supply and sanitation. Submersible pumps, according to their function, are divided into:

• drainage;
• fecal;
• wells;
• borehole.

Drainage pumps are used both for pumping water of various impurities at a depth of up to 7-10 meters, and for taking water from reservoirs or tanks.

Fecal pumps have much in common with drainage.At the same time, they are more powerful and durable, and can be equipped with a cutting nozzle. They are designed for pumping dirty water with inclusions, sewage water, fecal matter.

Well pumps are used to pump clean water (inclusion no more than 5 mm) from wells with a depth of more than 7 meters.

Borehole pumps are used to lift water from great depths. They are distinguished by high power, pressure force and high performance.

Pump selection

When choosing a pump, the following information is taken into account:

1. Flow rate. As previously noted, the performance of the pump must match the performance of the filter.
2. The voltage to which the equipment is to be connected. Models that connect to a 220V network are very popular. But it should be borne in mind that there are also models on sale that operate from a three-phase network.
3. Type of instalation. Pumps are submersible, semi-submersible and surface. For small pools, surface or semi-submersible type pumps can be purchased and installed. But for large pools, various water attractions with a large displacement indicator, a submersible model is suitable.
4. The type of materials used in the manufacture of the case. On sale there are models in the manufacture of which cast iron, stainless steel and plastic are used. Versions with high performance are usually made of cast iron and stainless steel. But cheap models are made of plastic. For long-term operation, design options are installed, in the manufacture of the body of which cast iron is used.
5. The presence or absence of a grinder. Various debris can get into the water.In order to protect the device from overheating or clogging, pumps with a chopper are installed.

It is quite important not only to choose the most suitable device, but also to install it correctly. If used incorrectly, even the highest quality equipment will quickly fail.

Overview of the best models

Among the popular models of pumps for the pool, one can single out the products of the most famous and respected manufacturers. Such models can definitely be included in the number of sales leaders.

Bestway 58389. Sand-filled model for outdoor pools. Budget and durable solution for home, garden. The built-in cartridge makes it easy to clean and maintain the filter.

The pump stands above its analogues, it is distinguished by high performance and workmanship.

The best heat pumps for swimming pools are produced by leading European manufacturers. The recognized market leaders include the Czech manufacturer Mountfield with its model BP 30WS.

Zodiak Z200 M2 from a French manufacturer also deserves attention. This monoblock with a rotary compressor and a titanium heat exchanger has a power of 6.1 kW, a throughput of up to 3 m3 / h, suitable for pools up to 15 m3.

The counterflow pumps with the most impressive performance are produced by the Swedish company Pahlen and the German Speck. Among them there are both embedded models and mounted, universal ones. The recognized sales leader is Speck Badu Jet Swing 21-80/32. No less popular is the Pahlen Jet Swim 2000 at 4 kW.

Operation and repair

Over time, the pump may fail. You can repair the product yourself, because the system has a not very complex structure. The main thing is to identify the cause of the malfunction.If the electric motor burned out, then there is no point in restoring the device. It will be cheaper to buy a new unit. The faults are as follows:

The pump does not pump water in full - replace the filter. If the replacement does not work, then inspect the hoses, probably a leak. Also, debris could get inside. Removing will restore the unit to normal operation.
The device works, but the liquid is not pumped. In this case, you need to inspect the engine blades. To do this, disassemble the pump. Replace a broken impeller by ordering it in a store or online.
The motor does not turn on. In this case, a wiring check and inspection of the contacts is required. At the junctions, they could oxidize. A fuse check will be required. Carefully inspect the plugs and sockets. Using the controller, check the pump, having previously disassembled it.
Change the filter element in time, following the instructions provided.
It is better to choose a pump with a filtering system based on the capacity of the pool. If the reservoir has a large volume, then it is better to purchase a unit that will pump large amounts of liquid without problems

It is important to follow the recommendations.

It is important to consider the nuances of using the pump before buying in order to choose the right unit

Pool filters

We must not forget about water purification. There are two filters for this: sand and paper.

Paper features:

• weighs less;
• easily replaced;
• lasts only a month, so it has to be changed often;
• purifies water from small particles, but can pass nanoparticles.

This option is suitable for pools that are not used too often.If there are more than 6 people in the family and they use the pond every day, it is better to purchase a more powerful device. It is worth thinking about purchasing a sand filter even if the pool is not located under a canopy, and various particles often get into it.

Sand Filter Features:

• weighs a lot;
• does not pass even nanoparticles;
• the contents should be replaced every 2-4 years.

The sand filter has more throughput. This is a product for large pools and for buyers with a big budget.

The main types of pumps and their suitability for the task

There are two main categories of pumps. They differ from each other in the depth with which they are able to pump out water. At the whim of nature, the source of life-giving moisture can be located at a depth of 5 meters, and very deep, at 50-100 meters.

The construction of a large private property is carried out for wealthy people. Therefore, future owners with significant funds do not particularly think about the depth of the aquifer, and the upcoming costs of water supply. In addition, the vast territory of the site allows you to choose the optimal location for the location of the well. But the owners of typical country plots are limited not only in choosing a location for placing the device, but also in choosing more advanced and expensive models. Although the main criterion that will determine the unit purchased for pumping water, the depth of the water carrier will still remain.

Deep water formation requires a powerful and complex device. Insignificant in depth allows you to get by with simpler and less powerful.But the first thing to consider is whether the equipment will be located outside, and then a surface pump is purchased, or it needs to be placed underground, and then you have to buy a submersible one.

What is the pump for in the pool?

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

The number is also affected by the presence of special zones: spa, hydromassage, fountains, sports, amusement areas.

Several types of pumps are involved in maintaining and ensuring the 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 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.
• Pump for creating countercurrent. It is used in the organization of hydromassages, water attractions, 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 for choosing pumping equipment for the water world of pools.

Why do you need to purify water?

A capital, stationary reservoir is not the only solution to the problem called "lack of water on the site." Small bowls - frame or inflatable - are quite capable of replacing such a tank. Their advantage is the ability to remove the structure when cold weather sets in. However, any container that stores water needs to be cleaned. There are several reasons for the need.

Daily water changes are an option that even the owners of very small pools are unlikely to like. Such an operation for volumetric bowls will take a lot of time, and if you also calculate the cost of one cubic meter of water, then it will simply “fly a pretty penny”. The best option is a monthly fluid change, however, no pool can be used without filters for such a long period of time.

The water in the bowl will quickly lose transparency, become a breeding ground for microorganisms, and therefore be dangerous for people. There is also no need to talk about the attractive appearance of such a liquid. Over time, unpleasant symptoms will appear - turbidity, insects, algae and an unpleasant odor. Frogs can become potential "residents" of such a reservoir.

To avoid getting to know all the undesirable consequences, they use a tandem - a pump and a filter. Forced circulation is the ideal solution from all points of view: in this case, there is no need to use chemicals that can affect the condition of allergy sufferers, young children and the elderly.

Kinds

The device is a product that pumps water at high speed. Pump types:

• With cartridges. In them, after a certain period of time, the filters that purify the water are replaced. This procedure takes place once a month.
• With sand element. Here, the flow of water passes through glass or quartz sand, located in a special container. The reagent needs to be flushed periodically (every week). An annual system overhaul is required. For this, chemicals are used.
• Combined.A generator is used here, which is a device that produces chlorine from simple salt. The resulting solution has an antibacterial effect.

Iodized salt and sand from the river will not work as a reagent for water purification. It is better to buy factory consumables that are designed for pumps and filters. Diatomaceous earth pumps are commercially available. Here, plankton powders are used as a filtering agent. Such reagents have high efficiency, but their price is higher. The disadvantage is the periodic replacement of the filter medium.

Separation according to the principle of action:

• Vortex and centrifugal devices. Such pumps have high noise and low productivity, but the products are inexpensive. Such devices are suitable for operation in pools with small volumes of water. Products will work flawlessly.
• Self-priming devices are often used for liquid filtration systems. They work quietly and do not require large financial investments, so their use is comfortable. The performance of the pumps is small. Such products are mainly used for small and medium-sized artificial reservoirs.
• circulation units. These units have the highest power. In just a day, they are able to filter the water several times in a large pool (4-5 times). In a small tank, this figure will increase to 6-8 times. The unit is suitable for large volumes, as well as for commercial use.

Which pumps are suitable for pumping water from the bottom of the pool

There are several varieties of water pumps, depending on the principle of operation and equipment, they are designed for different applications.For pumping water from pools and other containers in which the water is not clean, but not completely littered, there are self-priming drainage pumps.

The pump can be special, produced, as a rule, by pool manufacturers, or household, designed for widespread use. Depending on the cost of the reservoir, a pump for pumping out water may be included, but this is in expensive frame models. The bulk of the units has one manufacturer, but is supplied separately.

Types: submersible and surface (drainage)

There are two types of domestic drainage pumps that can be used to empty water.

• Submersible - sink to the bottom of the pool or other emptied container and pump out water through the grate in the housing. Do not require additional sleeves for work. Find out which pump to choose for a well here.
• Surface - remain outside, a special hose is lowered into the container, sucking out the liquid. In addition, you can also look at surface pumps for watering the garden.

For pools, they produce not only drainage pumps that can quickly drain water and at the same time clean the bottom, but also universal systems that operate in several modes:

• Circulation - they drive water in the pool for uniform heating and pass it through the purification system, preventing "blooming".
• Heating - they work both for draining, water, and for pumping it, while heating the cold water entering the pool.

The drainage pump can not only pump out water from the pool, with its help it is really possible to establish an irrigation system. Water can be pumped from a nearby reservoir or barrels with rain water.

The technology for installing a drainage pump in a well is described here.

How to fill up a tank?

Regardless of the type of device, there are general rules for preparing the pool for pumping:

• place the pool on the site where it will subsequently be located;
• the terrain should be flat, without hillocks and pits;
• make sure that there are no sharp or cutting objects that can damage the material;
• lay a tarpaulin on the platform.

Handheld Device Rule:

1. Connect the hose end of the device to the open valve of the pool.
2. Make forward movements with your hands up and down.
3. When the reservoir is tight, remove the hose.
4. Close the pool valve.

The principle of operation of foot models:

• insert the compressor hose end into the open pool valve;
• make rhythmic up and down movements with your foot until there is enough air;
• take out the hose;
• close the valve tightly.

How to pump up the pool with an electric pump:

1. Put the required handpiece on the pump.
2. Place the tip into the valve.
3. Connect the pump cord to a power outlet or car battery.
4. Turn on the pump.
5. When the pool is inflated, turn off and remove the device.
6. Screw the valve tightly.

Is it possible to use a car?

The tire inflation compressor has a thin tip, so before using it for the pool, you need to purchase an adapter or make it yourself.

Then you can get to work:

• put the nozzle on the tip;
• put it in the pool valve;
• connect the compressor to the machine;
• turn on the device;
• when the pool is inflated, turn off the device;
• turn the valve.

If the compressor becomes very hot during operation, it should be turned off and continue working after a few minutes. It is best to pump up the pool in this way in several passes.

How to inflate the pool with a compressor, the video will tell:

Overview of models and manufacturers

The selection of equipment begins with an inspection of how much this or that model costs.

But it is important to pay attention to the manufacturer. Here are some options for equipment for pumping / pumping water, which is well-deservedly popular:

1. Water cannon - equipment designed to pump flows from a well / well. The throughput of insoluble inclusions is low, the price is from $ 80
2. The kid is a design ideal for summer cottages. Low performance affects the low price (from $ 40).
3. A brook is a device for supplying water from wells and wells of medium depth. Unpretentiousness to the percentage of pollution, excellent performance, ease of installation and lightness of the device are complemented by a low cost (from $ 30), but the duration of operation is no more than 3-5 years.
4. The Gileks range is equipment designed for domestic use in both water supply and sewerage systems. Excellent practical qualities, work with different depths, unpretentiousness to pollution, a very long service life and good maintainability are the obvious advantages of the brand. Equipment cost from $200
5. Belamos - models are used to supply clean drinking water and irrigation. They have a built-in control unit, which facilitates the use of the units, and can work in manual, automatic and scheduled modes.There is also a filter to improve the quality of the supplied flow, overload protection, productivity up to 2800 l / h, supply depth up to 8 meters. Price from 150 $
6. Gardena is a brand of high reliability equipment. Universal devices are able to cope with the supply of liquid without interruption to high floors, be used for irrigation and at the same time are unpretentious to pollution, as they are equipped with a high-quality filter. Power up to 4000 l / h, ready for use immediately after purchase, the presence of 2 outlets for the hose (for irrigation and drinking water), a low noise threshold and a drainage tube for draining liquid add pluses to the device. Price from 120 $
7. Aquarius is an ideal pump for wells up to 45 meters deep. The reliability of the unit is confirmed by the execution of parts made of brass and stainless steel, there is a thermal relay, as well as a complete non-susceptibility to power supply drops (performance will decrease, and the device will not break). Silent operation is also a plus, but it is better to use the unit on clean streams. Price from 120 $
8. Whirlwind - pumps for deep wells (from 60 meters). Chrome-plated parts, durable housing, head up to 100 meters and price from $ 100 are the pluses of the unit. But energy consumption up to 1100 W is a drawback. However, the presence of overheating protection functions, smooth running, high pressure, high-quality assembly exceed the shortcomings.

All presented models from the Russian manufacturer have unique features - they are adapted to power outages, are resistant to mechanical stress and are easy to install. For users who prefer more expensive units, there are alternative options:

• The Grundfos range is an offer from German manufacturers.The company is engaged in the production of equipment for supplying and pumping liquids from wells, wells, tanks. The devices are equipped with sensors for overheating, overload, protection against dry running and voltage surges. Such functionality significantly extends the life of devices, but raises the price to $ 150. However, no matter how much the units cost, they deserve their price - the brand, according to consumers, is considered a leader in its field.
• Unipump is a brand of equipment indicated for use in wells with a high content of insoluble inclusions (up to 100 g/cubic meter). Feeding height up to 52 meters, productivity up to 4.8 m3/hour. There is overheating protection, soft start, automatic operation, but you will have to be careful in use if the liquid is very hard. The price is from $ 110, efficiency and noiselessness are pluses, but a weak network drive is a minus of equipment.

A preliminary analysis of the needs, the design of the water intake source, determining the length of the flow and the functional features of the water supply will allow not only to choose a good quality device, but also to correctly determine exactly how many pumps will be needed to uninterruptedly supply water to a house, household or suburban area.

Pump selection

When choosing a pump, the following information is taken into account:

1. Flow rate. As previously noted, the performance of the pump must match the performance of the filter.
2. The voltage to which the equipment is to be connected. Models that connect to a 220V network are very popular. But it should be borne in mind that there are also models on sale that operate from a three-phase network.
3. Type of instalation.Pumps are submersible, semi-submersible and surface. For small pools, surface or semi-submersible type pumps can be purchased and installed. But for large pools, various water attractions with a large displacement indicator, a submersible model is suitable.
4. The type of materials used in the manufacture of the case. On sale there are models in the manufacture of which cast iron, stainless steel and plastic are used. Versions with high performance are usually made of cast iron and stainless steel. But cheap models are made of plastic. For long-term operation, design options are installed, in the manufacture of the body of which cast iron is used.
5. The presence or absence of a grinder. Various debris can get into the water. In order to protect the device from overheating or clogging, pumps with a chopper are installed.

It is quite important not only to choose the most suitable device, but also to install it correctly. If used incorrectly, even the highest quality equipment will quickly fail.

Operation and repair

In most cases, installing pool pumps with your own hands does not cause much trouble. To connect equipment for pumping liquids, it is enough to follow the attached instructions, follow a number of simple rules.

For pressure and filtration models, it is necessary to prepare a waterproofing base

When operating indoors, it is important to maintain the temperature in it at least +5 degrees; when outdoors, the equipment is dismantled for the winter.
For the pump to work effectively, the height difference between the pump base and the water level in the pool should be between 0.5 and 3 m.

Rubber mats will help reduce noise and vibration during operation of the equipment.

The water suction pipe must be as short as possible. A strong slope of the line should be avoided, it is not recommended to change its direction.
When connecting to the network, it is recommended to equip the device with an automatic cut-off device that can protect the device from failure during power surges or short circuits.

Heat pumps are placed outside the pool, on a solid, level base.

The maximum length of the pipeline is up to 10 m.

All these tips help to connect the pumps more quickly and correctly. Of course, each type of equipment has its own subtleties that have to be taken into account, but general recommendations help you quickly find the right solution. When operating pumping systems, certain recommendations must also be observed.

Be sure to monitor the presence of a sufficient volume of liquid - any blockages, stagnation in the system are very dangerous, can lead to failure of the pumping equipment.

During the operation of the pool pump, its owner may be faced not only with the need for thorough water treatment, but also with the repair of failed equipment.

Among the common problems are the following.

Blocking the flow of water with air. It occurs when changing equipment and if it is located above the water level.In this case, if a circulation pump with a prefilter is used, it is necessary to turn on the equipment and wait until the filling occurs naturally (subject to the restrictions on the duration of dry running). Or pour liquid, and then make short starts for 5-10 seconds. In the absence of a built-in filtration system, a filler hole can be used for the same purposes, the actions continue until water appears, the sound of the equipment changes.

Problems with the pneumatic button on the control unit. Since it directly controls the inclusion of various types of pumping equipment, water attractions in the pool, the failed part will have to be replaced. With a piezo button, such problems no longer arise, the installation is similar, and you can increase the range of its placement.

Water does not circulate due to blockage in the system

To clean and unlock the hose, it will have to be disconnected from the system and mechanically "pierced" with a special tool for plumbing work or improvised means
It is important to handle the flexible liner with care, otherwise it may show breaks and cracks.

Filter clogged, water not circulating. To clean it, you will have to disassemble the pump of the cartridge cleaning element.
To do this, turn off the pump, turn the valve responsible for relieving pressure in a counterclockwise direction

Then you can open the filter and take out its contents, subjecting it to a thorough cleaning. After assembly, the system can be started again.

Water leak. If the pool water supply is poorly maintained, it can eventually leak at the connections. Most often, water leaks near the inlet and outlet, as well as at the filter attachment point.You can solve the problem by replacing the gaskets, tightening the connections. If a leak is found only on the inlet hose, the first step is to clean the filter.

Following these recommendations, you can easily cope with the tasks of maintaining and repairing pool pumps, and returning them to service after a breakdown.

Waiting for you in the next video operating tips pool pump.

Sandy

This is the cheapest type of filter, similar to a large tank filled with sand. In fact, sand in such structures plays the role of a filtering material (cleaning) and frees water from all kinds of contaminants. Quartz sand for pool filters is an element of a large fraction, which is much more efficient, only particles of at least 20 microns in size can be inhibited. Note that this will be enough to keep the water in the pool clean for a long time. Of course, it is best to choose a filter for an inflatable pool, which has the ability to change the water more often than is possible in large fixed models.

Sand filters for pools need weekly maintenance, that is, cleaning, otherwise the silted sand will cease to fulfill its function. For this, the reverse flow method is used, when water is driven through the filter in the opposite direction and washes away impurities from the sand. This process takes place under pressure and lasts for some time until the material is deeply cleansed, and therefore leads to impressive water consumption. Referring to this, we can say that the sand filter is not suitable if the use of water resources is limited.
