What is the name of the machine that pumps out sewage, and what types are there?

A private house provides the owner with many advantages:

• freedom of planning;
• freedom from neighbors' actions;
• many options for interior design and landscape design;
• choice of construction technology.

But living in your own home is also a big responsibility. A great way to manage your household wisely is with a sewer pumping machine. After all, in addition to decorating the home, the owner is faced with the task of competently solving exclusively everyday issues:

• heating;
• ventilation;
• sewerage

Main components of a vacuum cleaner

No matter how the sewage system in a private house is arranged, it is necessary to periodically pump out the contents. Sewage disposal is possible both on our own and with the help of a special sewage disposal machine.

Modern equipment is equipped with everything necessary to improve sanitary conditions quickly and efficiently. Installed on it:

• vacuum pump and tank;
• pipeline with tap;
• suction hose;
• various electrical devices;
• signaling and safety device.

Modifications of vacuum trucks

Such units are represented by a wide variety of models, which are used for the accumulation and subsequent transportation of various household waste. The most common options are those made on the basis of the following types of chassis:

1. GAZ 3309. Has the function of automatically turning off the power unit after the tank is completely filled. The model is equipped with a special process pump, as well as a hose, the length of which is 6 m. An additional safety mechanism is installed. The process of unloading waste in the tank is carried out by creating back air pressure or by gravity.
2. GAZ 3309. A similar model is equipped with a vacuum injection system with special pipelines, as well as a four-way valve.
3. GAZ 53. A sewer truck of this type, like GAZ 66, has a larger tank, as well as an additional compartment where clean water is located.
4. Kamaz 65115. An all-wheel drive chassis is used, which allows you to get to hard-to-reach places to clean septic tanks, as well as a spacious tank.

Specifications

Each model of the presented vacuum cleaners has certain technical characteristics on which their performance depends, as well as the price of such special equipment. It is worth considering the main parameters of such units:

The use of vacuum trucks is necessary for pumping various types of waste from septic tanks and their subsequent transportation to a disposal site.

There are different models that differ in tank volume, as well as other operating parameters and functions. External differences between the different options can be seen in the photo.

What does a sewer truck do?

Living in your own house, which has an autonomous sewer system, requires the services of a sewer when the drainage pit overflows. An overfilled septic tank makes the operation of the entire system difficult and contributes to its rapid failure. A family of several people calls a sewer truck on average three times a year. Pumping out does not cause difficulties when the machine has free access to the drainage pit.

Pumping out the contents of a septic tank is not the only use of a sewage disposal machine. For example, it is successfully used when carrying out repair work on sewer and water supply systems. It is also possible to simply pump out hot or dirty water from a cellar or basement.

A car tank can be used to transport technical and industrial liquids, in particular oil and petroleum products. The only thing that is not possible is the transportation of hazardous chemicals.

The services of special equipment may be needed by sanatoriums, cafes, swimming pools and other organizations whose activities are associated with mass visits of people. Sewage pumping is a sought-after service.

Sewer pumping in a private house

The operating principle of sewage disposal equipment

Vacuum trucks are used for pumping waste products from cesspools, sewers and waste pipes, for pumping water during the repair of water pipelines, flushing pipes, wells, wells from sludge contamination, and transporting all types of non-flammable liquids. Vacuum machines are typically operated by utilities and industrial companies.

For example, for cleaning channels with a large amount of mud sediments, the accumulation of which leads to emergency situations. In large cities where there is a centralized sewerage system, vacuum machines are not so in demand. In summer cottages and in private sectors it is difficult to do without them.

With the formation of large cities with central sewerage, drainage on roads and many enterprises, a need arose for specialized equipment that could fulfill a number of requirements:

• pumping and removal of waste from enterprises;
• elimination of consequences after sewerage accidents;
• elimination of flooding on roads after precipitation, when drainage networks cannot cope;
• pumping out various grease and starch traps (relevant for catering);
• pumping wastewater, waste pits and septic tanks;

You can list for a long time the various situations when the need arises to call a sludge sucker and sewage disposal machine.

Cleaning drain holes yourself

When choosing a sewer pumping method - with your own hands or with the help of a sewer truck - you should understand that it is important to comply with environmental standards and safety rules. This is difficult to do if you clean the drainage pit yourself. Therefore, you should definitely call the equipment and resort to the services of a sewer truck.

Types of sewage disposal equipment

At the dawn of the development of sewage disposal equipment, two model ranges of special equipment were sold. The first group included machines that carried out suction using the collector method, that is, due to the collector motor. The second version of special equipment is a built-in vacuum pump, which a little later was recognized as technologically advanced and rational. In the municipal sector, sanitary standards for sewage disposal machines were perfectly implemented using the implemented vacuum suction technology.

Vacuum sewer truck

The vacuum pump, according to the general technological structure, creates a vacuum inside the working tank (a completely sealed installation), as a result of which the effect of suction of the reinforced waste material occurs through a special receiving hose. Built-in special sensors automatically control and regulate the filling mode inside the tank, and when a certain capacity level is reached, they automatically turn off the vacuum pump.

Vacuum pump for sewer truck

The duration of operation of the suction system depends on the total volume of the tank; according to the technical data of the special equipment, the average duration of completely filling the tank is from 4 to 12 minutes. At the end of the suction process, the transport proceeds under its own power to the solid waste or solid waste disposal point, and the tank is emptied, either by gravity or using a pump.

In general, the types and types of special equipment for sewage disposal machines have the same operating scheme, but differ in:

• Tank filling volume;
• General technological capacity of the container;
• Dimensions and dimensions of the sewer truck;
• The brand of chassis on which the attachments are mounted.

The general structural structure of special equipment includes several elements:

• A cylindrical tank, which is mounted at a slight angle of structural inclination, for easy drainage by gravity;
• Vacuum pump of a special operating principle;
• Signaling sound and light safety equipment;
• Compartment with a receiving hatch and a built-in suction corrugated hose;
• Technological valve for operation of the pipeline system;
• Auxiliary attachments and electrical equipment.

An important part of the operation of sewage disposal equipment

Many people wonder how a sewer truck works, and what you need to know when using special equipment. The online magazine “About Special Equipment”, which is designed to provide information on the conditions for renting special equipment in Russia and the CIS countries, is ready to provide you with detailed technical descriptions for each group of vehicles used as specialized equipment on a rental basis.

As mentioned above, the sewer truck is equipped with a reservoir or sealed container for the disposal of pumped out concrete waste, a vacuum pump, a corrugated pipe for pumping liquid from septic tanks of any design, cesspools, common drainage wells, drainage technological complexes designed for car wash stations, as well as for natural reservoirs , small-sized ponds, etc. The general operating principle is as follows:

• One end of the working hose is connected to the tank of the machine, and the second end is lowered into the place where concrete or other liquid suspension is pumped out;
• Using a vacuum pump, liquid is sucked into the tank, allowing it to be completely filled. The alarm and safety device will automatically turn off the pump if the tank is completely filled;
• At the end of the work, the machine is self-propelled to a special disposal site that meets high sanitary and environmental safety standards.

“The main characteristics of a vacuum cleaner are presented in application to a specific vacuum pump model. Below is a table on the basis of which you can determine the technical parameters of pumping equipment for a specific model of special equipment.”

The technological valve on a sewage disposal machine is allowed for operation under certain environmental climatic conditions, and the minimum ambient temperature must be no less than -20 C, and the maximum ambient temperature +40 C. Exactly the same requirements for the operation of the machine in general, if it is used vacuum pump.

The maximum distance intended for collecting liquid ultimately depends on the length of the corrugated pipe, so the average size of such a pipe ranges from 6 to 15 linear meters. In some cases, with technological equipment, a sewage disposal machine allows the use of a corrugated hose, which has a length of up to 25 linear meters. In very rare cases, when the volume of the sewer truck allows it to accommodate a significant amount of reinforced waste, it is possible to extend the hose by another 5-10 meters, but the issue of extension depends, first of all, on the technical design of the vacuum pump. The extended sleeve size is used only if there is no other way for a vehicle to drive up to the place where the liquid suspension is collected.

In some cases, some models of special equipment have distinctive features from powerful sludge sucking equipment, and many users wonder what the difference is between a sludge sucker and a vacuum cleaner. In this case, you will be helped by the recommendations of specialists who will tell you about the fundamental difference between sludge sucking and sewage disposal equipment.

Pumping out sewerage using special equipment

Everyone knows the name of the machine that pumps out liquids - a sewer machine. The vehicle collects and transports liquid household waste. The machines that are usually called can be of several varieties, which belong to one of three types:

• sludge sucking machines;
• vacuum machines;
• combined machines.

Each machine designed for pumping sewerage is equipped with special equipment. In addition, it is necessary to have a receiving system with a volume of 5 to 7 cubic meters. This volume will allow you to clean the entire pit, the volume of which does not exceed 6 cubic meters, at one time.

Depending on what equipment can be used for the car, the method of pumping out the liquid is determined. The most popular are:

• Cleaning with a suction pump. The most popular and inexpensive way to pump out the sewer. At low temperatures, the use of this type of equipment is also possible due to the possibility of heating. Work performance may vary.
• Hydrodynamic method. The work is carried out in three stages: pumping out the drain, filling the tank with water, and pumping out again. Heating possible.
• Vacuum cleaning. This method can only be used using a vacuum pump. This type of sewer pumping machine can be used in almost any conditions. A certain distance from the place of purification is possible. The most versatile type of technology.

All types of machines are equipped with hoses whose length reaches 15 meters. This is not always enough to get the job done. The owner of the car, who is interested in its versatility, can equip the car with an additional hose. The possible loss of power is compensated by a longer operating time for each specific operation. If the distance to the object is more than 25 meters, it is possible to install a powerful vacuum pump on the KamAZ.

Septic tank pumping

Sludge suction mechanism

A sludge sucker has even greater capabilities compared to a sewage disposal machine. Its vacuum pump can pump out not only liquid, but also stagnant sludge. It differs from the sewage disposal tank design, which consists of 2 compartments. One transports pumped-out waste and silt deposits, the other contains process water. The tank has a filtration system that separates the liquid. The resulting water is used when it is necessary to flush a hole, well or pipeline. The sludge pump delivers it under high pressure to the walls, bottom, and hard-to-reach places, eroding the compacted sediment. After that, it sucks this water back using a pump and a hose (sleeve). After such cleaning, the drainage capacity of the pits and the operation of the structural elements of the sewer system are restored.

The sludge sucker can discharge the pumped waste like a dump truck. To do this, the wall of the rear tank is raised and folded back using a hydraulic system. In addition, the vehicle is equipped with an automated tank cleaning system. The sludge cleaner can operate at temperatures from -20°C to 40°C. If necessary, a remote control, additional hoses, and tools are built into its design. Japanese sludge suckers are the most popular because they are distinguished by true quality.

Sewage pumping machines help improve the environmental situation. The need for their work may arise at any time of the day.

Cost of work

When cleaning a septic tank on your own, the cost of the work includes the purchase of a pumping barrel and a pump. When using a vacuum cleaner, the cost of services consists of factors such as:

• Site location. The further away the place of work, the higher the cost of special equipment services.
• Tank volume. The larger it is, the more sewage the machines can pump out at one time, which means there is no need to call two machines. This is a significant cost savings.
• Location of the pit on the customer's premises. If it is not possible to get close, you need to use an additional hose and a more powerful pump. This increases the cost of work.
• Time to call the car. Using equipment outside of normal operating hours, such as in the event of an accident, costs more.

Working principle of pumping machine

A machine that pumps out sewage is a unit that consists of several components:

• tank;
• pump;
• suction and supply hoses;
• pipes;
• signaling device.

Operating principle of the sewage disposal machine:

• the suction hose is immersed in the filled container;
• start the engine, which drives the pump;
• pump out the pulp as far as the volume of the tank allows;
• transport wastewater to the discharge point.

If the amount of waste is large, you have to repeat the procedure several times until the tank is empty.

Varieties

Two types of sewage treatment plants are used. They perform the same tasks, differing only in the equipment for pumping out wastewater. The first type uses a motor manifold, the second uses a vacuum pump. Practice has shown the high efficiency of vacuum cleaning, so most types of special equipment use this technique. Today, every sewer pumping machine, the name of which has been preserved from ancient times, is equipped with a similar device. The technology differs from each other in its parameters:

• tank volume;
• engine power;
• chassis type;
• sizes.

The larger the car, the more spacious its tank. It is capable of pumping out large volumes of wastewater at a time. However, as the size increases, the throughput of the unit decreases. The length of the suction hose is not infinite, the standard size is 25 m.

Excessively large vehicles are used only in industrial complexes. Most often, installations are used on the chassis of a GAZ car with a tank with a capacity of 4 m 3. The minimum volume is 2 m3, but such special equipment is used only for cleaning cesspools or septic tanks in the private sector. To solve more complex problems, units on the KamAZ chassis are used. These are more powerful and capacious types of special vehicles.

Reviews from equipment owners

In order to form a complete opinion about the operation of a sewage disposal machine, you need to ask its owner a few questions. As a result of the analysis of the key characteristics of the cars, the following was revealed:

• The sewer pumping machine is extremely durable.
• Sewage equipment can adapt to different climatic conditions.
• Ease of use and reliability in operation are the main qualities of such a car.
• The use of this technique helps preserve the health of the ecological system.

Answers on questions

Before calling a vacuum cleaner, all our clients ask the same questions: What is the length of the hose of the vacuum cleaner?
How much does a vacuum cleaner cost? What is the volume of the sewer truck? Let's answer them in order. What is the length of the vacuum cleaner hose?

The standard hose length for a sewer truck of almost all brands is 10-15 m. This is the length of the hose of the sewer truck, which is included in the package by the manufacturer. But there are often situations when the standard length of the hose of a sewer truck is too small to complete the task. In view of this, organizations that provide sewage disposal services equip their equipment with additional hoses. And on average, after such modifications, the length of the hose of a sewer truck reaches 20-25 m. The question immediately arises: why can’t the length of the hose of a sewer truck be greater than this value? We answer, maybe. There is such a pattern: the longer the hose of the sewer machine, the greater the power loss of the vacuum pump. Therefore, if your distance from a possible access point to a service point is more than 25 m, then you need to call a sewer truck with a high-performance vacuum pump.

How much does a vacuum cleaner cost?

Find a more detailed answer to this question in the Prices section. If you did not find the cost of the services you need there, just call, we will ask you a couple of questions and will be ready to answer how much a sewer truck costs for you.

What is the volume of the sewer truck?

For each task, you can select the necessary sewage disposal machine. If it is necessary to pump out a large tank or storage tank, then the volume of the sewer truck should be maximum so that the number of trips is minimal. “Heavy”, high-capacity KAMAZ and MAN vehicles with a tank volume of 10-12 m3 are suitable here. If the task is simpler, for example, to pump out a dry closet, then a large volume of a sewer truck is not needed for such operations. ZIL or GAZ will do. The volume of the sewer truck in this case will be no more than 4 m3. When choosing which machine to order, you need to know exactly how much volume is expected to be pumped out. Otherwise you will have to overpay. Because The volume of the sewer truck directly affects the cost of the service. So first check the volume of pumping and only then can you call a sewer truck.

In this article, we tried to briefly but clearly answer the most common questions. We hope that after reading, you will not have any misunderstandings.
