home Pump equipment

Construction of the pumping station. Self-made ejector. Selection: built-in or external

The deep occurrence of the aquifer is a common problem that is well known to many land owners. Ordinary surface pumping equipment either can not supply the house with water at all, or it delivers it to the system too slowly and with a weak pressure. An excellent way out of this situation can be an ejector for the pumping station of water supply.

The deeper the water, the more difficult it is to raise it to the surface. In practice, if the depth of the well is more than seven meters, the surface pump does its job with difficulty.

Of course, for very deep wells, it is more appropriate to purchase a high-performance submersible pump. But with the help of an ejector, it is possible to improve the characteristics of a surface pump to an acceptable level and at a much lower cost.

Ejector - the device is small, but very effective. This unit has a relatively simple design, it can even be made independently from improvised materials. The principle of operation is based on the addition of additional acceleration to the water flow, which will increase the amount of water coming from the source per unit of time.

This solution is especially convenient for those who intend to install or have already installed a pumping station with surface pump. Ejector will increase the depth of water intake to 20-40 meters. It should also be noted that the acquisition of more powerful pumping equipment will lead to a significant increase in electricity consumption. In this sense, the ejector will bring a noticeable benefit.

The ejector for a surface pump consists of the following elements:

a suction chamber;
mixing unit;
diffuser;
narrowed nozzle.

The work of the device is based on the Bernoulli principle. It states that if the velocity of the flow increases, a low pressure region is created around it. Thus, the rarefaction effect is achieved. Water comes through a nozzle, the diameter of which is less than the size of the rest of the structure.

This scheme allows you to get an idea of the device and the principle of operation of the ejector for the pumping station. The accelerated reverse flow creates a low-pressure region and transfers kinetic energy to the main flow of water

A small narrowing gives a noticeable acceleration to the flow of water. Water enters the mixer chamber, creating inside it a region with a reduced pressure. Under the influence of this process, a stream of water enters the mixer through a suction chamber under a higher pressure.

The water enters the ejector not from the well, but from the pump. Those. the ejector must be installed in such a way that part of the water raised by the pump is returned to the ejector through the nozzle. The kinetic energy of this accelerated stream will be constantly transferred to the mass of water that is sucked from the source.

To create a region of rarefied pressure inside the ejector, use a special fitting whose diameter is smaller than the parameters of the suction pipe

This will ensure a constant acceleration of the flow. Pumping equipment will need less energy to transport water to the surface. As a result, its effectiveness will increase, as will the depth with which you can take water.

Part of the water produced in this way is recirculated through the recirculation pipe to the ejector, and the rest goes to the water supply system at home. The presence of an ejector has another "plus". It sucks the water by itself, which additionally insures the pump from running idle, i.e. from the dangerous for all surface pumps of the "dry running" situation.

The diagram shows the device of the external ejector: 1- tee; 2 - fitting; 3 - adapter for water pipe; 4, 5, 6 - corners

To regulate the work of the ejector, use a conventional tap. It is installed on a recirculation tube, through which water from the pump is directed to the ejector nozzle. With the help of a crane, the amount of water entering the ejector can be reduced or increased, thereby reducing or increasing the rate of return flow.

Option: built-in or external?

Depending on the installation site, the remote and built-in ejectors are distinguished. Great difference in constructive features these devices do not exist, but the location of the ejector still influences in some ways both the installation of the pumping station and its operation. So, built-in ejectors are usually placed inside the pump casing or in the immediate vicinity of it.

As a result, the ejector takes up a minimum of space, and it does not have to be installed separately, it is enough to perform the usual installation of the pumping station or the pump proper. In addition, the ejector located in the housing is reliably protected from contamination. The vacuum and return water are taken directly into the pump casing. No need to install additional filters to protect the ejector from clogging with silt particles or sand.

The remote ejector for the pumping station is more difficult to install than the internal model, but this option creates a much smaller noise effect

However, it should be remembered that this model demonstrates maximum efficiency at shallow depths, up to 10 meters. Pumps with integrated ejector are designed for such relatively shallow sources, their advantage is that they provide an excellent pressure of incoming water.

As a result, these characteristics are enough to use water not only for domestic needs, but also for irrigation or other economic operations. Another problem is the increased noise level, since the sound effect from the water passing through the ejector is added to the vibration of the running pump.

If you decide to install a pump with a built-in ejector, you will have to take care of the noise insulation especially carefully. Pumps or pumping stations with an integrated ejector are recommended to be installed outside the house, for example, in a separate building or in a caisson of the well. The electric motor for a pump with an ejector must be more powerful than for a similar no-jet model.

External or external ejector is installed at some distance from the pump, and this distance can be quite significant: 20-40 meters, some experts even consider the acceptable value of 50 meters. Thus, the remote ejector can be placed directly in the water source, for example, in a well.

The external ejector does not only increase the productivity of the pump, but rather increases the depth of water intake from the source, which can reach 20-45 m

Of course, the noise from the work of the ejector, installed deep underground, will not bother the tenants of the house. However, this type of device should be connected to the system using a recirculation pipe, through which water will return to the ejector. The greater the depth of installation of the instrument, the longer the pipe will have to be lowered into the well or well.

The presence of another pipe in the well is better to provide at the design stage of the device. Connection of the remote ejector also provides for the installation of a separate storage tank from which water will be drawn for recirculation.

Such a tank allows you to reduce the load on the surface pump, saving some energy. It is worth noting that the efficiency of the external ejector is somewhat lower than that of the models built into the pump, but the possibility of significantly increasing the depth of the fence makes you accept this disadvantage.

When using an external ejector, it is not necessary to place the pump station directly near the water source. It can be installed in the basement of a residential building. The distance to the source can vary within the limits of 20-40 meters, this will not be reflected in the performance of pumping equipment.

Erector mounting procedure

As already mentioned, the installation of an ejector built into the pump does not cause any special problems, since the device is already in the body of the device. The surface pump is simply connected to the water supply hose on one side, as well as to the water supply system - on the other hand.

If it is used as part of a pumping station, the pump is connected to the accumulator by means of a special choke for five outlets. In addition, the pump will need to be connected to the contacts of the pressure switch to ensure that it is automatically turned on and off.

This diagram clearly shows the procedure for connecting the remote ejector to the pumping station, indicating the locations of all necessary nodes

Before switching on the surface pump, it must be filled with water through the pouring hole provided for this purpose. Do not include such equipment without water, it can burn. If the pump is installed correctly, the ejector will work without interruption.

But the installation of a remote ejector is performed according to more complex scheme. To begin with, it will be necessary to install a pipe that will ensure a return flow of water from the reservoir to the ejector. A check valve is installed on the suction section of the ejector. After it, you should put a strainer that protects the device from clogging.

On top of the recirculation pipe, you need to install an adjustment valve to regulate the amount of water that is sent to the ejector. This site is not mandatory, but can significantly improve the situation with the pressure of water in the house. The less water will return to the ejector, the more it will remain for the water supply system at home.

Thus, it is possible to influence the water pressure in the water supply. At its lack, it is necessary to tighten the adjusting valve a little on the return line. If the head is too large and creates an unnecessary strain on the water supply system, it makes sense to send more water to the ejector to improve the efficiency of the pumping equipment.

Some industrial models of ejectors are already equipped with a system of such adjustment. The instructions that accompany the device usually describe in detail the order in which the ejector works.

Connecting a self-made ejector

The built-in ejector is usually purchased simultaneously with the pump, but the outer model is often manufactured by hand. It will be useful to consider the creation process and the procedure for connecting such a device. In order to make an ejector, such details as a tee with internal threaded connections, a union, fittings, bends, couplings, etc., will be needed. Assemble the device as follows:

Connect the lower part of the tee to the union so that the outlet branch is at the top, and the fitting with a smaller diameter is inside the ejector.
Then you need to refine the design by cutting the narrow part of the union, if it protrudes from the tee.
If the fitting was too short, it is enlarged using a polymer tube.
On the top side of the tee screw the adapter with external thread.
To the other end of the adapter with a fitting is attached water pipe PVC.
Now, to the underside of the tee, into which the narrow nozzle is already inserted, it is necessary to attach the elbow in the form of a corner.
To this branch a pipe is connected, through which the return flow of water to the ejector will flow.
A further corner is attached to the side branch pipe of the tee.
A pipe is attached to this corner with the help of a collet clamp, water from the well, wells, etc. will be sucked through it.

The distance between the edge of the tee and the fitting should be approximately 2-3 mm. This will ensure the creation of a vacuum area with the necessary characteristics. A fixing nut is used to secure the recirculation pipe.

It turns out that two elements are connected to the internal thread of the lower branch pipe of the tee. One of them (choke) is inside the tee, and the second (corner) is outside. To both fit on a single threaded connection, you must cut off part of the thread of the union.

Of course, all screw connections must be sealed and sealed. Most often for this purpose, the FSM tape is used. Sometimes to connect the ejector to the pumping station use not metal-plastic pipes, but constructions from polyethylene. For their installation, use special crimp elements, and collet clamps, which are good for metal-plastic, in this situation will not work.

All ejector screw connections should be carefully sealed and sealed, for example, with a FSM tape or other suitable material

About what pipes will be used to connect the remote ejector, you should think in advance. Polyethylene constructions are well bent when heated, which makes it possible to dispense with corners when connecting the ejector. The pipe is simply bent in suitable place and at the right angle, and then attached to the ejector.

To connect the ejector, it is possible to use pipes made of polyethylene, which are easier to install than similar structures made from metal-plastic

So, the device has three outputs, to each of which it is necessary to connect the corresponding pipe. First, a pipe is usually installed, through which water is taken from the source. It joins the lateral exit from the ejector.

At the end of this pipe, a check valve and a strainer are mandatory. This pipe should be long enough to descend deep under the water. But do not take water from the bottom of the source, as this can lead to clogging of the ejector, even though there is a filter.

Then it is possible to attach the pipe to the lower end of the ejector, in which a narrowed fitting is installed. This is the main line through which water is recirculated. The second end of this pipe should be connected to the tank, from which water will be drawn to create a return flow.

The third pipe is an ordinary water main. At one end, it is mounted on the upper nozzle of the ejector, and the second one is connected to the surface pump. It should be remembered that the diameter of the pipe through which water is drawn from the source must exceed the dimensions of the pipe through which water is fed into the ejector.

Three external pipes are connected to the remote ejector: a branch pipe for suction of water from the source, a pipe connecting the device with a pump and a line for recirculating water

If an inch tube is used on the feed, it is recommended to take the pipe a quarter of an inch more for suction. After all the connections are completed, the ejector is lowered into the water. Before the first start-up of the system, it must be filled with water. Pump is poured through a special hole. Pipes leading to the ejector must also be filled with water.

Before starting the pumping station with an ejector, it is necessary to fill the surface pump with water, as well as all pipes connected to the ejector

Pour water into the pump through a special hole.
Close the tap, through which water comes from the pumping station into the water supply system.
Turn the pump on for about 10-20 seconds and immediately turn it off.
Open the tap and bleed some of the air out of the system.
Repeat the cycle of short-time on / off of the pump in conjunction with bleeding air until the pipes are filled with water.
Switch the pump on again.
Wait until the hydraulic accumulator is filled and the pump is automatically turned off.
Open any water tap.
Wait for the water to flow out of the accumulator and the pump will turn on automatically.

If the water does not go off when the system with the ejector starts up, it is possible that air is somehow leaking into the pipes, or the initial water pouring was not performed correctly. It makes sense to check the presence and condition of the check valve. If it is not there, the water will simply pour into the well, and the pipes will remain empty.

These points should also be taken into account when using a pumping station with an ejector that starts after a long storage. Check Valve, the integrity of the pipes and the tightness of the joints are best checked immediately.

The lower branch pipe of the ejector, through which the water is drawn, should be protected from contamination by using a coarse strainer

If everything is in order, and water does not arrive, you need to check the voltage coming to the pumping station. If it is too low, the pump simply can not operate at full capacity. It is necessary to establish normal power supply of equipment, and the problem will disappear.

If the ejector is needed to improve the pressure of water in the system, and not to increase the depth of water intake, you can use the model of the self-made ejector described above. But it does not need to be immersed in water, it can be placed in a convenient place near the surface pump. In this case, the ejector will work in much the same way as the built-in model of industrial production.

Useful video on ejectors

In this video the issue of the depth of suction of the surface pump and the solutions to the problem with the help of an ejector are discussed in detail:

Here is clearly demonstrated the principle of the ejector:

Ejector is an uncomplicated but very useful device. It is a convenient and useful way to improve the performance of pumping equipment in a private home. But the installation of the ejector, especially the remote model, must be performed correctly, only in this way it is possible to provide a noticeable increase in the water pressure.

Ejector - what is it? This question often arises in the owners of country houses and villas in the process of building an autonomous water supply system. The source of water supply to such a system is usually a pre-drilled well or well, the liquid of which must not only be raised to the surface, but also transported through a pipeline. To solve such problems, a whole technical complex is used, consisting of a pump, a set of sensors, filters and a water ejector, installed if the liquid from the source needs to be evacuated from a depth exceeding ten meters.

In what cases is an ejector needed?

Before you deal with the issue of what an ejector is, you need to find out why you need a pumping station equipped with it. Essentially, the ejector (or ejector pump) is a device in which the energy of movement of one medium moving at a high speed is transferred to another medium. Thus, in the ejector pumping station, the principle of operation is based on the Bernoulli law: if a reduced pressure of one medium is created in the tapered section of the pipeline, it will cause the formation of another medium and its transfer from the suction point to be generated.

It is well known to everyone: the greater the depth of the source, the harder it is to raise water from it to the surface. Typically, if the depth of the source is more than seven meters, then a conventional surface pump already has a hard time fulfilling its functions. Of course, a more efficient submersible pump can be used to solve such a problem, but it is better to go another way and purchase an ejector for a surface-type pumping station, significantly improving the characteristics of the equipment used.

By using a pumping station with an ejector, the liquid head in the main pipeline increases, while the energy of the fast flow of the liquid medium flowing along its separate branch is used. Ejectors, as a rule, work in combination with jet pumps - water jet, liquid-mercury, mercury vapor and steam oil.

Especially relevant ejector for the pumping station is in the event that it is necessary to increase the capacity of a station already installed or planned for installation with a surface pump. In such cases, the ejector unit allows to increase the depth of water intake from the reservoir to 20-40 meters.

Overview and operation of a pumping station with an external ejector

Types of ejector devices

By its design and principle of operation, ejector pumps can fall into one of the following categories.

Steam

With the help of such ejector devices, gas media are evacuated from enclosed spaces, and a rarefied air state is maintained. Working on this principle devices have a wide range of applications.

Steam jetting

In such devices, the energy of the vapor jet is used to draw gaseous or liquid media from the enclosed space. The principle of operation of this type of ejector is that the vapor emitted from the nozzle of the installation at high speed carries away the transport medium leaving the annular channel located around the nozzle. Ejector pumping stations of this type are used mainly for the rapid pumping of water from the premises of vessels of various purposes.

Gas

Stations with an ejector of this type, whose operation principle is based on the fact that the compression of a gas medium initially initially under low pressure is due to high-pressure gases, are used in the gas industry. The described process proceeds in the mixing chamber, from where the flow of the pumped medium is directed to the diffuser, where its inhibition occurs, and hence, the pressure increases.

Design features and operating principle

Elements of the design of the remote ejector for the pump are:

a chamber into which the pumped medium is sucked;
mixing unit;
diffuser;
nozzle, the cross section of which narrows.

How does any ejector work? As stated above, such a device operates according to the Bernoulli principle: if the velocity of the flow of a liquid or gaseous medium increases, a region characterized by low pressure is formed around it, which contributes to the appearance of the rarefaction effect.

So, the principle of operation of a pumping station equipped with an ejector device is as follows:

The liquid medium, which is pumped by the ejector unit, enters the latter through a nozzle, the cross section of which is smaller than the diameter of the input line.
Passing into the mixer chamber through a nozzle with decreasing diameter, the flow of the liquid medium acquires a noticeable acceleration, which facilitates the formation of a region with a reduced pressure in such a chamber.
Due to the effect of rarefaction in the mixer of the ejector, a liquid medium, which is under a higher pressure, is sucked into the chamber.

If you decide to equip the pump station with a device such as an ejector, keep in mind that the pumped liquid medium enters it from the well, not from the well or well, but from the pump. The ejector itself is arranged in such a way that a part of the liquid that has been evacuated from the well or well by means of the pump is returned to the mixer chamber through a converging nozzle. The kinetic energy of the flow of liquid entering the chamber of the ejector mixer through its nozzle is transferred to the mass of the liquid medium sucked by the pump from the well or well, thereby ensuring a constant acceleration of its movement along the input line. A part of the liquid flow pumped by the pumping station with the ejector enters the recirculation pipe, and the rest into the water supply system served by such a station.

Having understood how a pumping station equipped with an ejector works, you will realize that it needs less energy to lift water to the surface and transport it through a pipeline. Thus, not only does the efficiency of the pumping equipment increase, but also the depth with which pumping out of the liquid medium can be increased. In addition, when using an ejector sucking the liquid by itself, the pump is protected from work idle.

The device of a pumping station with an ejector provides for the availability of a crane installed on the recirculation pipe in its equipping. By means of such a crane, which regulates the flow of liquid flowing to the ejector nozzle, it is possible to control the operation of this device.

Types of ejectors in the place of installation

Buying an ejector for equipping a pumping station, keep in mind that such a device can be built-in and external. The device and principle of operation of the ejectors of these two types are practically the same, the differences are only in the place of their installation. Ejectors built-in type can be placed in the inner part of the pump housing, or mounted in close proximity to it. Ejection pump built-in type distinguishes a number of advantages, which include:

minimum space required for installation;
good ejector protection from contamination;
no need to install additional filters to protect the ejector from insoluble inclusions contained in the pumped liquid.

Meanwhile, it should be borne in mind that high efficiency ejectors built-in type demonstrate if they are used to pump water from sources of small depth - up to 10 meters. Another significant disadvantage of pumping stations with ejectors built-in type is that they emit a strong enough noise in their work, so it is recommended to have them in a separate room or in the caisson aquifer. It should also be borne in mind that the ejector device of this type assumes the use of a more powerful electric motor that drives the pump unit itself.

External (or external) ejector, as its name suggests, is installed at a certain distance from the pump, and it can be quite large and reach up to fifty meters. Ejectors of remote type, as a rule, are placed directly in the well and connected to the system through a recirculation pipe. Pumping station from remote ejector also requires the use of a separate storage tank. This tank is necessary in order to ensure the constant availability of water for recycling. The presence of such a tank, in addition, allows you to reduce the load on the pump with a remote ejector, and reduce the amount of energy necessary for its operation.

The use of ejectors of remote type, the efficiency of which is somewhat lower than that of built-in devices, allows pumping the liquid medium from wells of considerable depth. In addition, if you make a pumping station with an external ejector, you can not place it in the immediate vicinity of the well, but mount it at a distance from the source of water intake, which can be from 20 to 40 meters. It is important that the location of pumping equipment at such a significant distance from the well will not affect the efficiency of its operation.

Production of an ejector and its connection to pumping equipment

Having understood what the ejector is and having studied the principle of its operation, you will understand that it is possible to make this simple device with your own hands. Why make an ejector with your own hands, if it can be purchased without any special problems? It's all about saving. Find the drawings on which you can independently make such a device, does not represent any problems, and for its manufacture you do not need expensive consumables and complex equipment.

How to make an ejector and connect it to the pump? For this purpose, you need to prepare the following components:

tee with internal thread;
choke;
couplings, elbows and other fitting elements.

The ejector is manufactured according to the following algorithm.

In the lower part of the tee twist the union, and do it so that the narrow branch pipe of the latter is inside the tee, but does not protrude from it reverse side. The distance from the end of the narrow branch pipe to the upper end of the tee should be of the order of two or three millimeters. If the choke is too long, then the end of its narrow branch pipe is grinded, if short, then build up with the help of a polymer tube.
In the upper part of the tee, which will be connected to the suction pipeline of the pump, screw the adapter with an external thread.
In the lower part of the tee with the already installed nozzle, twist the elbow in the form of a corner, which will be connected to the recirculation tube of the ejector.
In the side branch pipe of the tee, the elbow in the form of a corner is also screwed into it, to which a pipe supplying water from the well is connected by means of a collet clamp.

All threaded connections made in the manufacture of a self-made ejector must be leakproof, which is ensured by the use of a FSM tape. On the pipe, which will draw water from the source, you should place a return gate and a strainer that protects the ejector from clogging. As pipes, by means of which the ejector will be connected to the pump and the storage tank, which provides the recirculation of water in the system, it is possible to choose products from both metal-plastic and polyethylene. In the second variant, not collet clamps, but special crimping elements are needed for mounting.

The equipment that supplies water from wells is of two types: pumping station with remote ejector and built-in. Let's consider features of each of variants, that correctly to pick up the unit for itself.

The model with integrated ejector is characterized by a high degree of reliability in operation. It easily reaches the nominal water pressure, pumping water from shallow wells.

Features of functioning

The main parts of the pump station design with the remote ejector are at the top, and the device itself is transported to the bottom of the well. The drawbacks of this model include a small coefficient of efficiency and sensitivity to water with large impurities.

Pumping stations in which there is a remote ejector are used to supply water from a depth of 30 to 55 m. The apparatus with a separate ejector does not differ in anything from the usual pump unit. One difference is that two pipes come out of the well, on one of them an ejector is built, forming a system of "Venturi", thanks to which such a powerful water injection takes place.

The principle of the Venturi system is that the external ejector is lowered into the well and the pump is connected to two pipes: one of them is suction and the other is a return pipe. At their ends, an ejector is fixed which produces a deep suction effect with a borehole diameter of at least 100 mm.

Scope of application

Such an aggregate ensures the rise of water in the structure when the pressure is raised, it allows watering the garden and the private plot. The pump, like the ejector, is made of cast iron. Its working circle is made of brass, the rotor is made of stainless steel, the sealing is ensured by the use of a graffiti-ceramic cord.

For more efficient operation of the device, it needs to create certain pressure for the circulation of water. For such cases it is desirable to install a diaphragm tank, which will ensure that all conditions are met for the correct

Almost everyone who has ever directly participated in organizing the arrangement of autonomous independent water supply has occasionally encountered problems regarding the insufficient level of water supplied by the suction pump.

On the subject of physics, we definitely know and understand that such a factor as the pressure is capable of supplying the liquid as much as possible from nine-meter depths, but in fact, such an indicator is much smaller, which in fact amounts to about seven and sometimes five meters of high-grade filing.

The station that can increase the pressure of the water flow will solve the problem. Specialized equipment intended for such purposes is produced by modern industry, which is part of pumping stations.

Ejector for pumping station

From the article presented to you, you will learn in detail about the principles of the operation of such specialized equipment as a station with an ejector, as well as all the nuances and aspects regarding their application. In addition, ways will be considered for the possible manufacture of such equipment by independent forces with appropriate instructions and recommendations, through which you can achieve this goal.

Water supply station with ejector

Device. Operating principle

The ejector is essentially a device that transfers energy from one more fluid medium to another, which is less mobile. In the narrowing sections of the aggregate, a special lower pressure zone is formed, which thus provokes an additional medium. Thus, it is possible to move and remove from the suction points, due to the interaction of the original medium.

The units equipped with an internal format ejector are designed specifically for specialized pumping liquids from a relatively shallow type of wells, the depth of which does not exceed eight meters, as well as various reservoirs of dedicated storage or water reservoirs.

The distinctive feature of this interaction is the capture of liquids, which is located at a lower level from the nozzle. Proceeding from this, the pre-filling of the unit with water will be required. The working wheel will inject fluid that will redirect it to the ejector, resulting in the formation of an ejector jet.

It will move along a specialized tube and accelerate. Naturally, the pressure will decrease. Due to this effect and inside the suction chamber, it will decrease.

One of the varieties of such surface aggregates is a pumping station with an ejector. They differ in that the external element is immersed in a water supply source. Typically, the scope of such devices is similar to their counterparts. A certain difference lies in the different depths of use and application.

Pumping station with remote ejector

Manufacturing

It is quite possible to produce a simple device-assembly by independent forces. For this, some details, such as a special diameter tee and a fitting that will be located inside it, are required. It is necessary to observe the correct ratio of length, which should not be more or less, which will not allow the device to function normally. For fastening, you need a special adapter, equipped with corners, which will allow you to make the right turn.

The creation process involves several defined points, which includes the process of preparing the required nipple itself. Part of a special 6-faced specimen should be grinded, which will allow it to have a special cone, which has a base smaller than the external thread in diameter. After that, the deformed part should be corrected with a specialized threading tool.

The coupling must be screwed to the full stop in the tee piece. Extremely attentively observe when connecting the ratio of length, which is a fairly important factor. Be sure to seal the joint with any available sealant.

Check the ratio of manufactured parts, and then from the pre-prepared samples, you should organize a specialized adapter, which is designed for equipping on the pipe.

Qualitatively assembled station will provide a sufficiently long and trouble-free work, thanks to its simple constructiveness, but, naturally, you must be extremely accurate in manufacturing. If you do not want to be so interested in such a manufacture, you can simply purchase it in specialized stores, where there is always a pumping station in free sale.

Stations with built-in ejector - how to apply

A station is used to increase the head, which also excludes the possibility of premature failure of the unit, which provides the supply, since it may cause an idling. The presence of such an element in the system will exclude it, why it is recommended for mandatory integration into the system, regardless of the possible depth of the source.

Timely equipping with an ejector station will save you from additional costs and possible nerves in case of possible failure of more expensive equipment of the system, which it will simply prevent, providing full and uninterrupted functionality for a long time.
