Suburban construction is gaining momentum every year. It allows you to decide housing problem, guarantees Fresh air and a beautiful view from the window. True, with the infrastructure in most cottage villages big problems. Water supply is one of the most important. The well, of course, partially solves it, but the townspeople, accustomed to comfort, are not ready to put up with such a solution. Almost every site is installed or is already functioning autonomous system water supply Somewhere at their base there are wells, somewhere there are wells. In the latter case, surface pumps for summer cottages are the best option. Firstly, they are affordable and easy to maintain. Secondly, with a pumping station you can create comfortable conditions for accommodation. Everyone will be provided with water: the kitchen, the bathhouse, and the garden.

Purpose and design of a surface pump

The surface pump does not require immersion; only the water intake hose is lowered into the water. The maximum depth it can handle is nine meters. Therefore, it is not suitable for a well, but for a shallow well or spring it is just right. In addition, such a pump copes well with pumping water from basements and watering personal plot. Surface pumps are also great for wells on quicksand.

The maximum depth from which a surface pump can lift water is about seven meters. In this case, it is necessary to observe the “vertical-horizontal” ratio: for one meter of vertical there are four meters of horizontal

Surface pumps can be of three types:

• vortex;
• centrifugal;
• pumps with external ejector.

The first ones are the most affordable and compact. They create pressure 3-7 times higher than similar centrifugal ones, but have low efficiency - only forty-five percent. They must not be used to pump water containing a large number of sand or other impurities, as this leads to rapid wear of the impellers. Such a pump lifts water through a rotating shaft and a wheel on which “blades” are located. The latter transfer energy to the water from the working axis.

The latter are also not suitable for supplying heavily contaminated water, but they do an excellent job of removing air bubbles and plugs in the system. They are more expensive than vortex ones because they have more stages. This design works thanks to wheels that build up pressure. They are driven by a working shaft supported by bearing systems.

Installing an ejector significantly increases the maximum suction depth of a surface pump, but reduces its efficiency

Pumps with an external ejector are now practically not used. They were replaced submersible pumps, whose productivity is significantly higher.

There is a wide range of submersible pumps on the market. There are reviews of some of them on our website. For example, the “Rucheek” unit: .

Detailed Analysis: Pros and Cons of Surface Pumps

Surface pumps have many advantages:

• Compact overall dimensions;
• Light weight;
• Affordability;
• Easy to install, operate and maintain. Installing a surface pump does not require special knowledge, skills and experience;
• Ability to work with a water layer of less than 80 cm. In such conditions, submersible pumps can no longer operate;
• Cooling by air, and not by water, like submersible ones;
• High water pressure;
• High efficiency;
• No need to supply electricity to the water intake;
• High reliability and durability;
• Reliable operation even with air jams in system.

Also, surface pumps (as a class of equipment) have a number of disadvantages:

• Sensitivity to the presence of sand, impurities and other water contaminants;
• The maximum depth from which water can be raised is about nine meters;
• When using an ejector, the reliability and performance of the system are significantly reduced;
• Noise. It is better to allocate a separate room for the operation of the surface pump;
• The need to fill the suction line with water.

What to consider when choosing a specific model?

Depending on the purpose for which a surface pump is purchased, the characteristics that you should focus on differ.

Pump for watering a personal plot

In this case, the main equipment parameters are:

• Performance. One is enough to water the garden. cubic meter at one o'clock;
• The suction depth at which the equipment will be operated. The surface pump lifts water from a maximum depth of nine meters. In this case, you should remember the vertical-horizontal ratio, which is one to four. When working at a depth of two meters, the pump must be eight meters away from the well. If the suction depth exceeds four meters (or the total length of the supply line is more than twelve meters), the pipe clearance should be increased by ¼ inch;
• Pressure You should focus on the most distant point of consumption.

Using a surface pump, you can easily organize watering of your garden plot. The equipment is easy to install and does not require special installation skills

To connect a surface pump, the following components are needed: hoses (for water intake and for irrigation); fitting for connecting the hose and pump; a check valve and a mesh filter, which is installed on the check valve and traps sand and solid particles.

Quality hoses are the basis good plumbing for watering the garden. You will learn about which pipes are best to choose for these purposes in our material:.

Pump for home water supply system

When choosing a surface pump intended for water supply country house, you need to focus on the volume of water consumed, the number of consumption points and the required pressure in the system.

Designing a home water supply system based on a surface pump requires taking into account the volume of water consumed and the number of flow points

To simplify calculations, you can take the following values:

• A house for a family of four consumes 3 m 3 per hour;
• House for two families - 5 m 3 / hour;
• House for four families - 6 m 3 per hour;
• Personal plot - about one cubic meter per hour.

In dry times, water consumption can increase significantly; on hot days, 40-55% more than usual will be spent on watering alone.

In addition to these parameters, you need to pay attention to. If the value is set to 3.5 atmospheres, then the maximum pressure in the system must be greater than the total horizontal and vertical pressure of the supply line (distance to water plus 45-50 meters). A distance of 10 meters vertically or 100 meters horizontally equates to a pressure of one atmosphere.

To organize water supply at home, in addition to the pump itself, you will need the following components:

• Connection fitting;
• Inlet and outlet hose;
• Check valve with strainer;
• A hydraulic accumulator, the role of which is played by a tank with a capacity of 30-60 liters. It must maintain pressure in the system;
• Flexible line for connecting the pump and tank;
• Five-pin adapter for the second output;
• Pressure gauge;
• . It connects to a five-pin adapter. It sets the pressure values ​​at which the pump will turn on or off.

How to connect and start the pump?

The choice of pumping equipment is only the first, albeit important, stage. Next, close attention should be paid to the connection diagram of the surface pump and its first start-up. The service life of the equipment depends on this.

The surface pump must be placed on a stable surface before being connected. The equipment should be firmly secured to it to avoid possible displacement of the housing during operation. Then the incoming line is installed. A check valve is connected to the hose on one side (it is then immersed thirty centimeters in water), and on the other, the pump itself. The horizontal section of the hose must have a slope towards the water intake. When connecting components, you need to use fum tape or sealing flax.

The next step is filling the system with water. It is necessary to completely drain the incoming line and the pump. After this, the station is connected to the water supply distribution in the house. Be sure to close the filler hole if the pump was filled through it. The air pressure in the hydraulic accumulator is checked and brought to threshold values. The pump is connected to the electrical network. The entire line should gradually fill with water, then the accumulator tank. Once the pressure in the system reaches 2.6-3.0 atmospheres, the pump should automatically turn off.

To check the water pressure, you need to open any tap. Using the pressure gauge, you need to track the pressure value at which the pump will turn on again. If it differs from that recommended in the instructions, you need to adjust the switch and double-check everything again. After this, the system is ready for operation.

For many owners of private houses, cottages and summer cottages, the issue of water supply is very acute. Somewhere there is an opportunity to use central water supply, but somewhere not, so the problem is solved by drilling a well and installing pumping equipment that will pump water into the house’s pipeline system. Some build wells on their property simply to avoid paying large sums of money for what is already under their feet. Today we will tell you what is good or bad about a surface pump for a well, compare it with a submersible one and consider different variants decisions.

Surface pumps - what are they?

There are two types of pumps – submersible and surface pumps. You can guess their differences from the name, but to better understand the difference between these devices, you need to know them important characteristics. We will not understand the design, but will only discuss the most important differences.

Surface pump- This is a device belonging to the category of self-priming equipment. The maximum height to which it is capable of lifting water from the bottom of the well is 10.3 meters- This calculated value, derived as the maximum possible under normal atmospheric pressure. In fact, this value is at an even lower level - about 8 meters, since the operation of the equipment is influenced by various factors that cause power losses.

8 meters for production quality water, suitable for drinking, is of course not enough, so such equipment is supplemented with remote ejectors - devices that help increase the lifting depth to 40 meters.

Average performance surface pump is not at a very high level - from 1 to 4 cubic meters per hour, but this is completely enough to provide all the household needs of even a large family.

Operating pressure The output the hardware creates also varies greatly from model to model. Simple instruments have an indicator about 2 Bar, while more powerful ones can reach up to 5, which is equal to 20 and 50 meters of water column, respectively.

Submersible pumps are lowered directly to the bottom of the well and controlled using a remote block. They do not draw in water, but push it into the pipeline system, which makes it possible to use such equipment even in very deep wells. 200 meters is not the limit for them, but this applies to industrial equipment. For household use you just select a model required power, to the depth of your well.

Such equipment can provide very high consumption water - productivity on average is about 10-15 cubic meters.

What are the types of submersible pumps for wells? specifications prices and, of course, the main criteria for choosing such equipment. We will try to fully answer these important questions V

Comparison of surface and submersible pump

Which option should you give preference to on your site if the well depth is suitable for both types? Let's try to understand this issue. We need to know the following.

In general, you will decide for yourself what to buy, and we continue to introduce you to surface equipment.

Types of surface pumps

We have already mentioned in passing that the surface pump is a self-priming equipment. This means that it can independently remove air from their pipes, which is inaccessible to submersible and circulation pumps, which together are called normally suction.

A standard surface station includes not only a pump, but also other elements:

1. A hydraulic accumulator or membrane tank in which a certain volume of water is stored to maintain normal pressure in the pipeline.
2. Suction pipe.
3. Outlet pipe.
4. Shut-off valves for control and measurements.
5. Filter system.

All surface pumps are vane pumps, but the fluid can move differently in the working chamber. According to this parameter, pumps are divided into vortex and centrifugal. What is the fundamental difference?

Centrifugal pump

A centrifugal pump has a constantly rotating impeller consisting of two disks installed in parallel. There are blades between them. The parts rotate in different directions.

Several such wheels can be installed in the system, which determines the power of the device and its purpose. In appliances used in everyday life, the wheels and motor have a common shaft and are located in the same housing. In equipment industrial use A separate arrangement is more often used, but all parts are always installed on the same frame. The engine is connected to the working shaft through a belt or transmission drive.

In principle, this is all that the user needs to know about such pumps, since the rest of their capabilities relate to industrial equipment.

Vortex pump

In a vortex pump, despite the presence of blades, water moves in a different direction and according to a different principle. The working chamber has a ring shape; the discharge and pressure pipes are connected to the channel, separated by a seal. As water passes through, it twists into a double screw, like a chain of DNA. Due to the centrifugal force from the action of the screw, it enters the outlet pipe, in which the acceleration force of the water is converted into a pressure force.

In a centrifugal pump, water moves along the shaft, and after passing the wheel, it can immediately change directions to axial, radial or perpendicular, which depends on the design of the unit.

Vortex pumps are capable of creating very high pressure, however, they are characterized by large energy losses, and as a result, the efficiency drops significantly compared to centrifugal ones. Therefore, they are given preference only when there is no other choice, or when a really powerful pressure is needed.

Another advantage of a vortex-type station is its ability to better pump liquids with a high content of water-insoluble impurities, such as sand or clay. So, if you need water not for drinking, but, for example, for irrigation, and you do not intend to install a filter system, vortex units are what you need.

Basic parameters for choosing a pump

So, we have already written about the height to which the water needs to be raised. What else should you pay attention to when choosing? We need to know exactly the distance of the well from the house, and the volume of pumped liquid, which will depend on the total volume of the water supply network and the maximum possible water consumption at any given moment. A trivial example: we open the tap closest to the point of entry into the building - we get good pressure, open the second one - the pressure drops, and at a remote point the water flow will be the smallest.

The calculations here are, in principle, not complicated; you can do them yourself using online calculator, or simply by studying the instructions from the manufacturer.

Advice! Appliances, working with water, needs to constantly maintain the pressure in the pipeline at a level not lower than 0.3 Bar. Consider this point also when choosing a pumping station.

What does the pressure in the system depend on? It depends on the power of the pump and the volume of the hydraulic accumulator - the larger it is, the more stable the average pressure in the water supply. The fact is that when turned on, the pump does not work constantly, since it requires cooling, and when the operating pressure is reached, it should not continue to increase it. The system is designed in such a way that it pumps water into a hydraulic accumulator, in which a check valve is installed, which prevents water from flowing back when the pump is turned off. When the pressure in the tank reaches the set threshold, the pump stops. If water withdrawal continues, it will gradually drop, reaching a minimum level, which is a signal to turn on the pump again.

That is, the smaller the accumulator, the more often the pump is forced to turn on and off, the more often the pressure will rise and fall. This leads to accelerated wear of the engine starting equipment - in this mode the pumps do not last long. Therefore, if you plan to use water from a well constantly, buy a tank with a larger capacity for the pumping station.

When constructing a well, a casing pipe is installed into it, through which water rises. This pipe may be different diameters, that is, it may have different throughput. Based on the cross-section of the casing pipe, you can also choose the right equipment for your home.

Interesting to know! The most popular casing pipe size today is 100 mm.

All the necessary information will be in the instructions for the purchased pump. You can also get recommendations from the specialists who are drilling your well. They will know exactly the optimal operating parameters. It will also not be superfluous to make some reserve in the power of the unit so that the pressure in the system rises faster to a comfortable threshold, otherwise water will constantly flow sluggishly from the tap.

Installation of a surface pump

Now let's see how to connect the pumping station to the well and pipeline system Houses.

Table 1. Necessary equipment and materials for pump installation

Photo	Description
	We remind you that this equipment consists of the pump itself and a membrane tank. They are connected to each other with a flexible or rigid connection, depending on the device model. A wire comes out of the pump housing on the motor side to connect it to electrical network.
	If the pumping station is not equipped with its own filter, then it must be purchased separately. This device will purify water from impurities of sand, clay and other substances.
	We also need a hose for water intake. For this we use a corrugated product, which can be additionally equipped with a coarse filter. There will also be a second hose in the system for water supply. It can be replaced by a pipe system included in the caisson.
	A check valve with a filter prevents water from the pipeline from flowing back into the well
	We will need plumbing tape to seal the threaded connections. You can also use plumbing thread or flax (tow). The latter option has long established itself as the most reliable - most plumbers use it in their work.

As for the tools, we will need a set of wrenches - adjustable or cap wrenches, and a gas one for working in difficult places and fixation round pipes. If electricity has not yet been installed in the caisson, then add a cable to the list the required section, corrugation for its insulation and an overhead socket.

Table 2. Surface pump installation

Steps, photo	Description
	If your house has a basement, then it is best to install the pump there. This will allow without unnecessary hassle get to it when you need to inspect equipment and repair it. Also, you will not have problems connecting the station to the electrical network. And most importantly, the pump will be in a dry and warm place, which will have a positive effect on its operating condition and service life. With this arrangement, it is connected to a pipeline that extends through deep trenches into the caisson, where it connects to the well casing.
	The pumping station must be securely fixed, therefore an installation site is first organized under it, the surface of which must correspond horizontal level. If this condition is not met, the unit may soon fail due to imbalance. The pumping station is attached through special holes in the frame. We use fasteners, depending on the base material - for concrete we use metal screw anchors, and for wood, self-tapping screws are enough.
	Then we move on to connecting the pump inlet with the pipe from the well. The diameter of the pipe or hose should not be less than the diameter of the inlet of the unit, otherwise you will get a bottleneck effect, and as a result, a drop in the power of the equipment. Before making connections, fum tape is wound onto the threads. Interesting to know! The counter nut will have a gasket that should hold water on its own, but it’s always better to be on the safe side - especially since, thanks to the presence of an additional seal, you won’t have to pull it all the way. For the same purpose, you can install an additional gasket. We connect a corrugated hose to the pump inlet. If necessary, include a coarse filter in this chain.
	We screw a check valve onto the other end of the hose, also pre-sealing the connection with fum tape. Then we immerse this end into the well or casing pipe, and make sure that it has reached the desired level. There is no point in lowering it to the very bottom, since, despite the presence of a filter, the system will draw a lot of sand, which will lead to accelerated clogging of the filter elements and a significant drop in pressure. Ideally, the valve should not reach 30-50 cm to the ground, and be immersed in water to a depth of at least 1 m.
	Any surface pump has a supply hole into which, before starting, you need to fill water to the required level to avoid dry operation. If this is not done, the unit can be broken without ever using it. The supply hole may be in different parts, depending on the pump model. Therefore, be sure to read the instructions and understand the issue. So, fill the supply hole with water so that the fill hose and the pump housing are completely filled.
	Next, the pumping station must be connected to the house pipeline. If you use the equipment for watering, then the principle will remain the same - screw on the hose, stretch it to the location, and place sprinklers or a gun tap on the other end. Advice! To avoid the transfer of vibration from the pump to the pipeline (especially important for equipment installed in the basement of a house), it is worth using a corrugated hose designed to work with the pressure stated on the pump as a flexible connection to the pipes.
	Next, connect the power cable from the pump to the outlet. We also connect a portable float, which will prevent the pump from working without water if its level in the well drops. Before you make the first start, you will need to open all the taps in the house so that the air in the system can escape freely. Don't forget about toilets.

That's it, now you can turn on the equipment. As soon as water flows from the taps, turn them off and let the pump draw required pressure V membrane tank. Now your home has a complete water supply system.

Video - Quick connection of a surface pump

During the installation of equipment for wells, submersible structures are often used. But surface aggregates are often used. The described structures are not lowered into water, so their body is not exposed to negative impact environment. Surface devices are divided into vortex and centrifugal. The first type of devices is used to lift water with increasing pressure, and the second are designed to lift liquid from shallow wells. It is worth remembering that if a artesian well, it is worth purchasing more expensive and powerful equipment, since only powerful units are capable of lifting water from a depth of more than 20 meters.

Advantages and disadvantages of surface mechanisms

In the case where a shallow well was drilled at the site, surface devices are used. Such mechanisms have many advantages when compared with deep-well electric pumps:

The disadvantages of the described electric pumps include the ability to operate only at shallow depths. Another disadvantage is that for normal operation of the device it is necessary to install special filtering equipment. If this is not done, the mechanism may fail.

Before turning on the surface pump, you should make sure that it does not start pumping air during operation. Disadvantages also include high level noise during pump operation. It is worth remembering that surface self-priming pumps can only be installed in insulated structures.

How to choose

Before choosing an electric pump for a well on your site, you need to learn about the criteria on the basis of which it is worth purchasing such products. First of all, you need to know how much water will be pumped daily. To supply water to a country house, you will need a more powerful pump than a design for water supply to a greenhouse.

When choosing, the following data must be taken into account:

1. If 4 people live in the house for which the mechanism is purchased, you should choose a device that pumps 3 cubic meters of water per hour. This volume is enough for the whole family. If it is necessary to pump water also to supply water to the greenhouse and vegetable garden, the consumption doubles.
2. When installing a surface mechanism to provide water to a townhouse, you need to purchase devices with a capacity of more than 5 cubic meters.

The well for the surface pump, which is created on the site, must have a depth of less than 20 meters. If the depth is greater, you need to take a closer look at more powerful types of devices. Typically, for wells deeper than 25 meters, centrifugal pumps are purchased.

How does the installation work?

Installation of the electric pump is quite simple. In order to start using the device, you only need to select a location for installation and then connect the pipes. To perform such work it is not necessary to hire specialists, but to install the pump you must have minimal experience work with plumbing equipment.

The pump is installed as follows:

1. At the first stage, the location for the equipment to be installed is selected. It is best to prepare a separate structure for installation. It is worth placing it near the well. It is worth remembering that it is necessary to insulate the created structure.
2. After this the creation occurs concrete foundation for the mechanism. Metal fasteners for the described equipment are installed in the base. Metal studs allow you to neutralize the load that constantly affects the structure during operation. If equipment is not protected, vibration can cause it to become unusable in a short time. At this same stage, the installation of a surface electric pump occurs.
3. Then the equipment is installed to control the unit. Many automatic systems are already configured and ready for installation. If you have the knowledge, you can assemble the pump control unit in parts. If you are not familiar with the structure of such mechanisms, you should not assemble them yourself. This unit includes sensors as well as control relays that control the water level and other parameters. When the water supply stops, the relays help stop the pump.
4. On next stage The pump pipe is connected to the water supply system. During connection, it is necessary to install a check valve on the pipeline. This device prevents water from overflowing and draining after the pump is turned off.
5. Then the installation occurs expansion tank. Before you start connecting, you should check the pressure in the chamber. This indicator must correspond to that declared by the manufacturer. If the pressure does not match, it must first be adjusted.
6. On last stage The cables for the installed surface electric pump are connected. In this case, it is important to make a dedicated line for supplying electricity.

After connecting the surface pump to the well, it is necessary to check its functionality before turning it on for continuous pumping of water.

It is necessary to connect a surface pump to draw water from the well. But let's start with a little description and background. There is a house in which water supply is implemented according to the diagram below:

More details: There is a well. A submersible pump is lowered into it, which draws water from the well into a settling tank located in the house. This is necessary so that sand and other debris settle in it. Water is pumped into the tank automatically. For this purpose, a float sensor is installed in the tank. Next, through a filter system, the pumping station draws water from the sump and supplies it under pressure to the water supply circuit of the house. The pressure created by the pumping station is sufficient for simultaneous operation washing machine, dishwasher and shower work.

Everything in this scheme is good. Except for one thing - the submersible pump may break. It's one thing when something like this happens in summer time. And it’s completely different when in winter it’s minus forty outside, you have to dismantle the well, remove the pump, install a new one, and then insulate everything again. In general, there is nothing pleasant about this. This happened in this case too...

To prevent a repetition of the above situation in the future, it was decided to install a surface pump instead of a submersible one, because If equipment fails, you won’t have to wait for a thaw to replace it.

What you will need

• surface pump (in this case Kraton pwp-370);
• hose;
• adapters G1-herringbone 3/4;
• check valve G1();
• clamps.

Surface pump connection

Here is the culprit of winter well removal:

After dismantling it, we have a hose with a diameter of 3/4 in our hands. We insert the adapter G1-herringbone 3/4 into it.

And we fix the connection for reliability with a clamp.

Next on threaded connection screw on the check valve. It would be a good idea to use flax to improve the quality of the threaded connection.

After this, lower the hose from check valve into the well.

Let's move on to the equipment. Surface pump Kraton pwp-370 has two threaded holes 1" in diameter each. One of them is for water intake, and the other is for supply (in our case, for filling the settling tank). To connect hoses with a diameter of 3/4 to it, you will need two adapters G1-herringbone 3/4.

We screw the adapters into the pump. Be sure to use flax or other sealant for threaded connections.

We connect the hoses. One coming from the well, the other from the tank.

We fix the hoses using clamps.

The surface pump is ready to draw water from the well. But before you start pumping water, the system should be prepared for the first start.

First start of the surface pump

It is very important that there is water in the system. If it is not there, the surface pump will not pump water. Moreover, when working dry, it can overheat and fail before it has had time to work. This means that before starting the equipment, the pump itself and hoses should be filled with water. For these purposes, there is a plug on its body. Unscrew it and fill it with water.

It’s rare that someone manages to fill the circuit with water the first time. Especially if there are reverse slopes. As a result, water is pumped intermittently weak pressure or not relevant at all. To completely eliminate air from the circuit, you should start the pump briefly, and after turning it off, slightly unscrew the air release plug. This manipulation should be repeated until the water flows with uniform, good pressure without “spitting.” At this point, we can assume that the connection of the surface pump to the well is completed.

The lack of running water and sewerage is what can poison life in any, even the most beloved dacha. Endlessly carrying buckets of water can eventually tire anyone, even if the well is located a few meters from the house. However, solving this problem is simple - you just need to buy a water pump.

All water pumps are divided into two groups according to installation method: submersible and surface. Submersible pumps will be discussed in a separate article, but today we will talk about what a surface pump is, how it works, what its disadvantages and advantages are.

What is a surface pump

A surface pump is a pump that does not require immersion in water to operate. The pump is placed on the surface, and the water intake hose is lowered into the water. The advantage of such a device is that the surface pump is easy to maintain. Its main disadvantage is that a surface pump is not capable of lifting water from great depths. The maximum depth from which a surface pump can pump water is only about 10 meters. This means that it is not suitable for drawing water from a deep well or borehole. There are submersible pumps for these tasks. A surface pump is perfect for watering a garden or for pumping water out of a basement.

Surface pumps can be divided into two types:

1. Vortex surface pumps have a very small suction depth. Most often, such devices are used not for drawing water, but for regulating the pressure level in the water supply.
2. Centrifugal surface pumps. Another name for them is self-priming surface pumps. Such pumps have a greater depth of water intake than vortex pumps, which means they are quite suitable for taking drinking water from a shallow well or irrigation water from a pond.

Speaking about surface pumps, I would like to say a few words about pumping stations. In addition to the pump, the pumping station includes a control unit and a pressure storage tank. Some models also include a device that protects the station from overheating. An important component of the pumping station is the hydraulic accumulator. The pumping station operates according to the following principle: the pump supplies water to the accumulator, then the pump is turned off and water from the accumulator is used. When the water in the accumulator drops to a fixed level, the pump turns on again.

How does a surface pump work?

A centrifugal surface pump is a device that operates due to wheels located inside it that pump up pressure. The wheels rotate due to the working shaft located in the housing. The shaft, in turn, rests on bearings. Thus, the water entering and exiting the centrifugal surface pump has different speeds and pressures.

Vortex surface pumps are similar in design to centrifugal pumps. The centrifugal pump housing contains an axis on which the impeller is mounted. There are special blades on the wheel, which transfer energy from the rotating axis to the water.

If you are going to purchase a surface pump, then it will be useful for you to know what characteristics of the unit you should pay attention to so as not to make a mistake with your choice. First, decide for what purpose you want to buy a surface pump. For simple watering of the garden, you can purchase a surface pump with a low capacity. If you are going to organize country house individual plumbing system, then the pump performance must be high. For watering a garden, a capacity of 1 m3/hour is sufficient.

When purchasing, pay attention to such pump characteristics as suction depth. Average maximum depth The suction of the surface pump is 8 meters. For a surface pump, the vertical-horizontal ratio is 1:4. That is, 8 meters vertically is 32 meters horizontally. Knowing this ratio makes it possible to calculate what maximum suction depth is required to use the pump in your area.

Also determine the maximum pressure of the surface pump. To do this, you need to calculate the distance from the place where the surface pump will be located to the most remote point of your site where water supply will be required.

And one more nuance. If you know that the network voltage at your dacha is low, then buy a pump more powerful than required by the parameters listed above. Otherwise, at a time when the network voltage is low, the pump’s performance may be lower than what you need.
