Sewer installations - the principle of choice. Sewage installations Automatic sewage pumping unit

Grundfos sewage pumping units of the Multilift series are small in size, compact, hermetic, complete units, which are mainly used for collecting and pumping sewage wastewater located below the standard level from residential, administrative and industrial buildings. The Grundfos Multilift pressurized sewerage station is available in several different models: from simple single-unit type M systems to more global and large-scale installations MDV, MD1. In particular, units that have one pump in their composition are classified as M / SS, the same ones that have pumping system doubled, called MD / MLD. Both the first and the second, in fact, are complete devices, that is, they are already completely ready for connection, installation and operation. Any sewer and waste type media, any other contaminated liquids with elements of solid and fibrous particles (with an acidity level of not more than 10 and not less than 4, with a temperature not higher than 40 degrees Celsius and not lower than 0 degrees Celsius) can be used as working fluids in them. ).

Features and Benefits:

Up to five motor sizes available for each tank size (M, MD, MLD); - finished units include check valves(MSS, M, MD, MLD); - less weight means more ease of operation and installation (MSS, M, MD, MLD); - easy to use microprocessor with preset values ​​for two different levels (MSS, M, MD); - two adjustable inlet heights in one system (MSS, M, MD); - reliable work of the microprocessor provides control over work; - high-quality pressure sensor, not in contact with sewage and a separate signaling device high level water; - flexible inlet pipes using connectors or fittings. - the possibility of ordering three main inlets with a diameter of DN100 with two additional inlets provides maximum flexibility - a wide range of tank sizes for each type of application: 66 - 100 - 120 - 270 - 450 - 900 and 1350 liters;
- rounded bottoms of the tanks, preventing sedimentation and lowering the level of residual wastewater;
- sealed material made of polyethylene, providing impermeability to gases and odors;
- non-synchronized Vortex impellers that pass solid inclusions up to 80 mm in size.

In almost all cases when sewers are designed, they try to make their system self-flowing. With such a system, the discharge of effluents through the pipes will occur with the help of gravity. Unfortunately, it is not always possible to use such a system. This is due to two main factors:

• heterogeneous complex relief;
• remoteness of the collector from the connection point.

These factors do not allow laying pipes with a slope. When this happens, a sewer installation will help resolve this situation.

When constructing new buildings or when carrying out repairs with redevelopment of old ones, it often turns out that it is absolutely impossible to lay sewer pipes with the correct slope. That is, it is impossible to make an outflow of effluents on your own. It is in such cases that the sewer system becomes the main assistant.

Equipment designed for the forced pumping of sewage is called sewage installations. As mentioned earlier, they are very useful and necessary in cases where the point of use of water is at a remote distance from the place of its reception, as well as when it is necessary to ensure the movement of effluents through an ascending pipeline.

In many situations, a sewer installation will be an indispensable solution:

• cottage sewer system;
• apartments in the basement;
• offices;
• clubs;
• hotels.

The pumping unit makes it possible not to pay attention to where the bathroom is located in the building. In situations where the city network is located up the slope near the building, installation will also be necessary. You should be aware that these pumping units can move wastewater a certain distance. It reaches about 100 meters horizontally or 11 meters vertically.

Components of sewer installations

The sewer plant is a small, almost silent system that is very easy to install and does not cause trouble in maintenance. Its main specialization is the diversion of wastewater in forced mode. The following parts are located in the middle of the sealed housing:

• pump;
• grinding mechanism;
• special filter against odors;
• check valve;
• pressure meter.

All major components of the system remain unchanged. Some details may vary according to the installation model. Depending on the purpose, you can use a common pump at the installation or a special installation, which is separately installed at points with the same properties of wastewater. Systems for diverting water with faeces into without fail have a cutting mechanism.

Choosing one or another pumping station for fecal or sewage should be based on the following factors:

• the depth of the inlet collector;
• type of stock liquid;
• equipment control method;
• the amount of wastewater in the area.

There is currently huge assortment models from different manufacturers of this system. The required sewer system is selected depending on the conditions of use. You can connect all plumbing either separately or together.

Basic working principle

When the waste water enters the receiving area, the pressure sensor is activated and the pump is turned on. After that, the effluents follow the grinder and exit through the pressure pipe. When the water supply stops, the same pressure sensor stops the pump, and check valves prevent the return of effluents through the unit.

The sewer installation has another fat plus. Its drainage pipe has a small diameter. This will hide the pipes in the walls and reduce the amount of work.

You should not complicate your life if you can simply install a gravity flow sewer system without pumping equipment. If, nevertheless, there is a need for a sewer installation, then it should be given to its choice a large number of time and attention.

Leading brands of manufacturers and models

For quite a long period of time, the following companies were leaders in this area:

• GRUNFOS from Denmark with the SOLOLIFT series;
• Spanish ESPA with their creation called SANI;
• French SFA.

Small systems from these manufacturers, with a head of 3-11 m, can pump about 3.9-18 m 3 / h.

The sewer system with the Clean cutting factor will be the most suitable and optimal solution mainly for all bathrooms of a residential building. This installation capable of delivering 50 l/min to a height of 6 meters and 90 l/min to a height of 3 meters. This installation consumes only 0.42 watts of electricity.

Much attention must be paid to GRUNDFOS models. All equipment of this company will be able to quickly divert runoff water from washbasins, sinks or showers. In order to organize the removal of wastewater from the toilet, a special installation model will be needed, which is designed for liquid with solid waste. This is the SOLOLIFT 2 WC 3 model. Its design includes a special cutting mechanism. It is designed to grind all kinds of solid inclusions along with toilet paper.

cutting mechanism This model has a special self-cleaning system. It prevents the formation of sediment in the tank and the occurrence of various unpleasant odors.

This model has a number of advantages:

• very compact size;
• simple installation process.

The best and most versatile option, especially for large wastewater needs, is the Drainbox sewage pump model. This system the good thing is that it can be installed in your own home, club, restaurant, cottage or even in a small hotel. This becomes possible due to the fact that the system pumps wastewater at a rate of up to 77 m 3 /hour. The flow and head vary depending on the configuration of the system.

A.Installation of DRAINBOX
B.Inlet pipeline
C.Return valve with pressure line
D.Siphon
E.Ventilation piping
F.Pump for emergency emptying of the sewer system
G.Drainage pump

Drainbox can be installed with one or two containers, respectively 300 or 600 liters. Based on the target requirements of the consumer, the installation can be equipped with either one or several pumps.

Simplicity and reliability

Simplicity is one of the most significant and main advantages of sewer stations. If you read the instructions very carefully, then the entire installation process can be done by yourself. If the device becomes clogged or malfunctions, you should contact the warranty in technical Center. At the time when the warranty period expires, cleaning can be carefully carried out by yourself. If you do not throw foreign objects and household garbage into the toilet, then the sewer station will serve you well for many years.

Choosing a sewer installation is a very difficult and responsible task. This system has very a large assortment and therefore, decisions on a specific model should be made together with a specialist. He examines everything in detail and carefully. specifications, according to your needs, and help you make a choice.

Overview of the GRUNDFOS sewage pumping unit:

The organization of a traditional sewerage system operating according to a gravity flow scheme is far from always possible. Especially when implementing private projects country houses there is a need to use pressure lines that provide pumping of wastewater. This solution complicates, but without a special circulation activator in this case not enough. In technical terms, this problem is solved by a household sewer installation, which is small in size and has sufficient power potential to serve a specific network.

General information about sewer installations

By their design, such units resemble those designed to work in specific conditions and with a specific carrier. The range of models is quite diverse, but even entry-level installations allow servicing highways located at a height of 5 m. Stations that are more solid in terms of capabilities are able to work with a 15-meter level. Also modern models such devices do not impose strict requirements on the configuration of the location of consumers - the distance from the connection point can reach 100 m. However, this distance depends on the power that the sewer installation has in a particular design. Manufacturers supply such systems and additional features. For example, it is advantageous to equip the same private houses with pumps, which include shredders. By means of cutting elements, the plant crushes and mixes the masses served, bringing them to a homogeneous state. This procedure facilitates further discharge of wastewater through pipes with small diameters.

The principle of operation of forced sewage

AT traditional performance the installation is a pump, which includes the principle of operation is built according to the same scheme as in areas with irrigation systems. Through two nozzles, inlet effluents enter the tank, after which they can be subjected to grinding or other operations in preparation for a further stage of movement. The final stage involves the withdrawal of effluents into the main line.

Typically, for domestic needs, a compact sewer installation is used, the design of which allows it to be directly connected to modern plumbing. For example, in this way it is possible to organize the diversion of wastewater from washing machine, toilet bowl, sinks, from the laundry room, bath room etc.

Main selection criteria

In the selection process, two important parameters should be taken into account. The first concerns power and, accordingly, performance. The average power consumption is 3 kW, which allows the unit to serve about 18-20 m 3 / h. The second selection criterion concerns the execution of the structure. Again, in classical form surface sewer installation provides for the presence of two branch pipes that provide input, as well as one output channel.

There are other configurations that should be correlated with the existing system both in terms of the number of channels and the dimensions of the station. For example, there are models that can even be placed in a drain tank, and there are also large-format units that require installation separate place in room.

Installation of a sewer installation

Much in the technique of installing and connecting equipment depends on the purpose of the model. So, there are special units for bidets, showers, toilets, etc. In each case, the sequence assembly operations may be individual. But there is also general principles installations, in accordance with which a sewer installation can be qualitatively installed with your own hands and without the help of plumbers.

Work begins by connecting the inlet to the drain pipe from the target equipment. Further, the reverse side of the pumping station is brought to the main line, which will provide the output of wastewater. In both cases, it is important that the unit is initially located on a stable surface - for this you can also use the fasteners included with the station. If the installation and connection are performed correctly, then the unit can be connected to the electrical network.

Nuances of operation

Modern sewage pumps are supplied or equipped with optional electronic control systems, therefore special attention does not require installation from the user. You can set the unit function to optimal parameters work and operate normally. But it is important to note that installations of this type can cause inconvenience due to high noise levels. Also, many users note vibrations that spread along walls and ceilings. Installation made using allows you to level negative factors. If during installation this nuance was missed, then during operation it is recommended to place absorbent supports made of wood or soft plastic under the body.

In addition, during the work pumping stations require regular updating of filters. Therefore, it is important to change the absorbent in a timely manner, which is usually Activated carbon- it should be placed in the capacity of the cleaning container.

Reviews of Grundfos models

The German manufacturer enjoys great confidence among Russian summer residents, who widely use pumping equipment. Sewer stations of this brand are also highly valued for their small size, sufficient performance and reliability. In particular, the Conlift and Multilift models are specially designed for operation in private households. A universal solution can be a sewer installation in the Sololift modification. It is distinguished by its low weight and high throughput. But, according to the owners small houses, this option may be too powerful for entry-level communication systems.

In buildings where it is not possible to connect to a centralized sewerage system, it is necessary to look for alternative ways to organize it. This problem is most relevant for owners of private buildings. For the disposal of wastewater and their subsequent processing, special systems are used for the forced pumping of household waste and their removal from the building - sewer pumping units.

Purpose and varieties

This equipment is designed to remove sanitary and technical wastewater. Depending on the location, they should be divided into internal and external sewer pumping units.

Internal

Indoor or submersible equipment is mounted directly at the place of collection of liquid waste: collection tank, gutter, sump, etc. The ingress of effluents into them occurs independently, due to the slope of the pipelines of the sewerage system. As a rule, such installations are used in suburban areas.

outdoor

These products are a combination of a collection tank and a special pump. In this case, the installation of a sewer is carried out in high-rise buildings, office buildings, multilevel technical and industrial premises, in other words, in those places where a gravity sewer system is not possible due to a difference in the height of the laying of pipelines. When installed at the lowest accessible point, this type of equipment is capable of forcibly collecting storage tank drains and their subsequent movement to a place where free flow of gravity is possible.

Cutter equipment

Many sewer pumping units are additionally equipped with a special grinding mechanism that allows you to pump liquid with a high degree of pollution. Through the action of the rotating steel blades, the solid large constituents of the sewage are destroyed, thereby preventing clogging of the sewer system.

Underlying Factors

When choosing, you need to pay attention to the following main factors:

Depending on the type of liquid being pumped, the installation of a sewage pumping station may be required for:

• Drainage of waters that are formed on treatment facilities as a result of precipitation.
• Removal of household sewage.
• Disposal of industrial wastewater to treatment facilities.
• Storm water drainage.

When purchasing sewer equipment, you need to pay attention to the following:

Popular manufacturers

Among consumers, the most popular manufacturers are Denmark, France, Germany. Consider the models of pumping units that are most in demand among consumers.

Grundfos

The manufacturer of this equipment uses durable materials in the manufacture. The Grundfos sewage pumping unit is corrosion resistant and may have various sizes and tank volumes.

The models of the Sololift series are quite in demand among consumers. This equipment is characterized by small overall dimensions and can be used to treat toilet waste. It can grind toilet paper, solid fractions, and most importantly, it is easy to install. approximate cost such an installation from 15,500 rubles.

This manufacturer also produces Multilift sewer pumping units, which are designed for pumping and collecting wastewater (with feces) located below the level of the sewerage system:

• Cafes, offices, hotels, hotels.
• Plumbing systems for fitness clubs, saunas, etc.
• Semi-basement apartments, single or multi-family houses.

The cost of such a product is approximately 71,500 rubles.

Wilo

They differ from this manufacturer in a wide variety: with one or more pumping units, with different volumes of the receiving tank, with a grinding mechanism.

Among everything model range I would like to highlight the equipment of the DrainLiftS series. This automatic sewage pumping unit is fully prepared for use, it can also be used for draining sewage with faeces. The station is different various options installation: wall mounting, sewage disposal from a separate building, connection to a toilet bowl.

The system is equipped with a tank of 45 liters, on average its cost is about 70,800 rubles.

SFA

The main feature of these plants is simplicity and high performance. They are allowed to be installed in public places where serious loads are possible.

SFA Sanivite sewage equipment is designed for domestic use and is characterized by compact size and low noise level.

Conclusion

Sewer pumps are safe and practical equipment. It provides residents with the proper level of comfort, and most importantly, the quality is in no way inferior to the central stations.

What if the sewer outlet is higher than the plumbing outlet? How then to organize the removal of wastewater? In private houses, they made a pit into which drains were collected, from there they pumped submersible pump into a sewer or septic tank. Today there is another solution - a sewage pump. In many cases, its installation is cheaper, and even easier - that's for sure.

Device and purpose

A pump with a chopper is a surface sewer pumping unit that allows you to organize the removal of wastewater where it is not possible to do this using a gravity system. This is a small plastic container with a powerful built-in pump that pumps wastewater into the sewer. Drainage can be moved both vertically and horizontally. There are installations with a grinder that can be connected to toilets, there are without a grinder - for "gray" drains from sinks, showers, bidets, etc.

Application area

A sewer pump is used in cases where it is impossible to make a gravity sewer system. In most cases, when a plumbing fixture, washing machine or dishwasher is installed below the sewer inlet. For this, forced sewage pumps were invented. This solution allows you to transfer bathrooms and technical rooms to the basement or semi-basement.

Another pump with a chopper is installed if it is decided to make the bathroom after the repair is completed and the sewerage system has not been connected to the place of the proposed installation of plumbing. In this case, the installed equipment is connected to a compact sewer pump, and it is connected to the sewer. What's the Difference? In the following:

• the diameter of the outlet pipes for the sewer pump is much smaller than for the gravity system (28-40 mm);
• drains can rise up to a height of up to 9 meters;
• horizontal sewage disposal is possible up to 100 meters (requires a minimum slope of 1-4%).

All this allows minimal cost organize a connection to an existing sewerage system almost anywhere.

Device and principle of operation

The sewer pump consists of a storage plastic container and pump. Some models that can be connected to the toilet have a chopper. The filling level is monitored by a sensor. When it works, the chopper and pump turn on, the waste is pumped into the sewer system. Shutdown controls the second sensor - it turns off the power when the level of drains falls below a certain level. This is a simplified algorithm for the action of a pressure sewer.

There are sewer pumping stations designed to connect devices of various types and quantities. The simplest one is designed to connect one or two devices, the most productive one has three additional pipes (and one main one). Accordingly, the container has one or more inlets (depending on the model) and one outlet. Pipes coming from plumbing are connected to the inlets, and the outlet is connected to the sewer.

For pumping high-temperature effluents from washing and dishwashers, bathrooms there are special models made of heat-resistant materials. A conventional sewer pump cannot cope with such a load. Therefore, to connect such equipment, you need to look for certain models.

Advantages and disadvantages

The main advantage of compact individual sewer installations is that they allow you to equip the sewer without carrying out large-scale construction or repair work. With their help, complex tasks are solved:

• Drainage device when plumbing fixtures are located below the entry point to the sewer system.
• Equipping a bathroom without carrying out large-scale civil works.

Another positive point is the use of small diameter pipes. Most of toilet pumps are connected to the sewerage using plastic pipes diameter 28 mm - 32 mm - 40 mm. Only high capacity installations require 50mm pipes. Such plumbing networks are easier to hide. Even if it was not possible to hide them, they do not attract as much attention as the standard one hundred millimeters.

However, there are also disadvantages:

Well, the main drawback is that the pumps burn out. If the power and performance are selected correctly, unsuitable items do not get into the sewer, they can work for years. But with a selection error, when the equipment is operated at its limit, the pumps often fail. Therefore, when choosing a sewer pump for a toilet, it is better to take it with a margin of performance. It will cost more, but such an installation will work longer.

Classification and types

There is no single classification of forced sewage installations, but they can be divided according to several parameters:

When choosing a pump for forced sewage, it is worth remembering that they are not designed to connect a bath. The bathrooms contain too much water, pumping out which the pump will overheat and block. As a result, it will take a long time to drain the water from the bathroom. There are only a few models of forced sewage that can handle this task - SFA Saniplus Silence and Sololift C3. These sewer pumps are great for large quantity drained warm water.

Other companies offer to make an intermediate pit for forced pumping out of the bathroom, into which to drain the water. From it, pump it into the sewer with any suitable device. Given that the pit must be below the level of the drain, this method is not always acceptable. And, despite the high cost of SFA Saniplus Silence and Sololift C3, it is more profitable to install it than to carry out a huge amount of excavation.

To prevent overfilling of the tank, there is an additional alarm device. In some companies, it simply beeps when the tank is full, in others it also turns off the device connected through it (washing machine or dishwasher).

Installation and connection rules

Installation and connection of pumps for toilet bowls and forced pumping of drains from different manufacturers occurs according to very similar rules. But before installation, you should read the instructions for a specific product - there may be features.

A sewage pump can stand in the kitchen - to drain drains from the sink and / or dishwasher

Connection

The installation location must be chosen so that the pump can be reached. It does not require special maintenance, but periodically there is a need for cleaning. If a dishwasher and a washing machine are connected to the pump, it is better to regularly check whether the sewer installation is clogged with grease, dirt, and salt deposits. If necessary, cleaning with mild detergents is possible. Aggressive chemical compositions it is better not to apply, as they can damage the plastic and rubber parts of the installation.

So here are the general rules:

In general, installing and connecting a sewer pump for a kitchen or toilet is not a very difficult undertaking. But provided that you already have some idea about working with plumbing. In this case, you can do everything yourself.

Outlet pipeline features

Compact plumbing toilet pumps can pump drains not only vertically, but can also lift them up. In the presence of vertical section in its lower part, it is desirable to provide for the possibility of draining - if you have to clear the pipeline from blockage, it is better if the drains are drained in a certain place, and do not start pouring out during work.

The height of the vertical section of the outlet pipeline is determined taking into account the minimum slope of the horizontal section. Each manufacturer (sometimes each model) minimum slope its own, but in most cases it is 1-4% (1-4 cm per 1 meter).

Be careful. The description of the sewage pumps indicates maximum height lifting of drains and the maximum distance of transportation horizontally. For example: 8 m up, and 80 m horizontally. But this does not mean that by lifting the pipe 4 meters up, it will be possible to transport another 80 meters horizontally. In this case, after a four-meter rise, the length of the horizontal section will be no more than 40 meters. Just climbing 1 meter up "takes away" about 10 meters of horizontal transportation. This is important and worth remembering.

Manufacturers and models

Not many companies produce individual sewer installations. However, the price range is quite wide. Traditionally, European manufacturers are distinguished by good quality, but high prices. No one will be surprised if we say that Chinese sewage pumps cost less, but their quality is worse. In general, the choice, as usual, is expensive and high quality, or cheaper and…

Forced sewage installations Grundfos (Grundfos) - Sololift (Sololift)

The well-known plumbing manufacturer Grundfos (Grundfos) produces pumps for forced sewerage Sololift (Sololift). On the this moment launched a modified line of Sololift2. It has no moving parts in contact with drains. The exception is the chopper, but its drive is also “dry”. This makes the renovation less of a hassle. There are several Sololift models for different occasions:

Sololift sewer pumps are not the cheapest equipment, but they work reliably and correspond to the declared characteristics. The firm also supports warranty repairs.

Pumps for toilets, bathrooms, kitchens and technical rooms SFA

This company specializes in the production of sanitary pumps. There are several lines for solving different problems, connecting various devices:

SFA products work reliably and cost a little less than Grundfus. You can choose a model for any combination of plumbing. In general, the SFA sewage pump is a good option. Installation of equipment is standard - put in any convenient place. There is only one limitation - it is better that the branch pipeline starts from a vertical section, if there is one on your route. If this is not possible, the length of the horizontal section should be no more than 30 cm.

The height of the vertical section is calculated taking into account the fact that the horizontal section must have a slope towards the inlet of at least 1% (1 cm per 1 meter of pipe).

Aquatik CompactLift fecal pumps

Toilet pumps Compact Elevator is manufactured by the Chinese company Aquatik. It's over a budget option individual sewer installations. Differ in low level of noise.

At the moment there are only three modifications:

Aquatik guarantees its bathroom and toilet pumps for 1 year from the date of sale. Violation of operation (the presence of fibrous inclusions in drains) may cause a denial of warranty repairs.

Willo sewage pumps

The German company Willo is known for making reliable devices. Toilet pumps are no exception. Good quality plastic, thick tank walls, reliable pump. There are the following models:

The range of Willo sewage pumping units allows you to solve any problem if you need to equip bathrooms and toilet rooms in private houses. For commercial or more intensive use, Willo has other solutions.

Pressure sewer pumps STP (Jemix)

These customized sewer units are made in China. The price category is average. Reviews, as usual, are different - someone is completely satisfied, someone absolutely does not like it.

So, here are the sewer pumps Jemix offers:

It differs from those described above by increased power - some models raise drains by 9 meters. Most of the above sewer pressure pumps can raise drains up to 4-5 meters. So this is where the Jamixes win. In this parameter, they have only one competitor - Sololift Grundfos with its lifting height of 8 meters. But his price category is completely different (as is the quality, however).
