Vacuum and sludge removal equipment on KAMAZ chassis

A sludge sucker (SMV) is a type of municipal equipment designed to remove sludge from sewer wells, all kinds of storage tanks and further transportation to the disposal site (for example, pumping out septic tanks, cleaning a car wash). Also in a flammable version (AKNS) it can be used to collect oil field waste.

In sludge extractors manufactured by NPO Vector, unloading occurs using a hydraulic system for raising the tank and opening the rear bottom. The machines are also additionally equipped with a hydraulic washout system, which allows you to wash off adhering bottom sediments inside the tank.

Compared to similar types of municipal equipment (for example, vacuum machines), the equipment in question is equipped with a more powerful pump. The device easily collects dense settled sludge.

Pumps used

AKNS Vector uses various vacuum pumps: KO-505, PNR-122/124, PVT-200, PVT-400, VK-6M2, NVR-8/3.

For MVS sludge suckers it is necessary to use more powerful pumps. Jurop models (PNR-122/124, PVT-200, PVT-400) are suitable for these purposes.

Our company can carry out individual configurations of sludge sucking machines, at the request of the customer.

Who sets the tone in the industry?

The leading enterprise among domestic specialized manufacturers of sludge sucking machines is Arzamas. This company controls about 96% of the domestic sludge sucker market. The plant produces 7 models of the KO series with tanks with a capacity of 3.35 to 7 m3 and a pulp collection depth of up to 8 m. A powerful vacuum pump with a capacity of 730 m3/h fills the tank in 3–7 minutes.

The popularity of Arzamas machines is determined not only by their good quality, but also by their low price, as well as their reliable and simple design. Actually, focusing on the last two indicators is a priority for the management of the enterprise.

Mtsensky, one of the oldest in the industry, also focuses on reliable but inexpensive design solutions. Based on the experience of 60 years of practice, 5 models of KO series sludge extractors with tanks with a volume of 7 to 10 m3 are produced here. The company installs sludge suction equipment on KamAZ and MAZ chassis, but in agreement with customers, installation schemes on Isuzu, Volvo, Hyundai, Iveco, Man, Ford, Dongfeng chassis have been developed and are used.

Mtsensk cars are distinguished by high-quality painting of all components and parts, neat and reliable welded joints. Innovative rubber sealing profiles perfectly seal the tank, and the material of the suction hose is designed for many years of reliable operation.

One of the most modern enterprises in Russia in the municipal sector - was created in 2009. Today it produces more than 20 models of various municipal equipment, and among them - 6 models of sludge sucking machines on various chassis: KamAZ-53605, KamAZ-65115, KamAZ-43118 , MAZ-6312A9, Ford Cargo 1826, Ford Cargo 3535.

The most powerful sludge sucker in the TverKomMash line is the TKM-630. It is assembled on the basis of the three-axle MAZ-6312A9. This chassis has a comfortable cabin with a “sleeping bag”. The volume of the tank is 12 m3 for sludge and 1 m3 for the sludge washout system. The suction pump uses a vacuum pump with a capacity of 4100 m3/h, which makes this machine the most powerful in its class among domestic manufacturers. This pump is a maintenance-free type pump designed for continuous operation. For the operator’s convenience, a drum with a 15 m long suction hose is located on the rear cover of the tank. This drum has a hydraulic drive (winding and unwinding), which greatly facilitates the operator’s work.

Thus, the TKM-670 sludge extractor uses the Ford Cargo 3535D chassis as its base. The steel tank is made of a 6 mm thick sheet, with partitions - breakwaters - welded inside it. The internal part is coated as standard with a layer of zinc-containing substance, which reliably protects the surface from corrosion. By agreement with the customer, the interior of the tank can be made of stainless steel. Another option for anti-corrosion protection involves the application of a polymer anti-corrosion wear-resistant coating, which increases the service life of the tank to 15 years.

To load sludge on TverKomMash equipment, various types of vacuum pumps are used: Italian Battioni air-cooled, with a capacity from 650.4 to 840 m3/h. At the request of customers, it is possible to equip it with MORO or Jurop vacuum pumps with a capacity of up to 1500 m3/h. The machines are optionally available with a sludge washing system.

The customer can choose to unload the tank either by the dump principle - by lifting the tank with a hydraulic cylinder rod, or by creating excess pressure in the tank.

The sludge suction equipment has a reliable safety system consisting of three safety valves, one of which is installed on the tank, and two in the pump group, as well as mechanical locks of the rear bottom and the tank in the raised position.

The Moscow enterprise Dorkomtekhnika produces 3 models of suction pumps. The productivity and volume of the tanks of these machines are selected in such a way that they will satisfy the requirements of any buyer of this equipment. Sludge extractors of the DKT series are suitable for both utility services of small enterprises and municipal services responsible for cleaning city sewer networks, since Dorkomtekhnika produces machines with tanks with a volume of 3.6–10.4 m3. The company uses sludge sucking equipment and vacuum pumps from the famous Italian company Jurop to complete its machines.

For more than 55 years, JSC “Zavod Start” from the Kurgan region has been producing tanks for transporting food products. Today, the plant's tank trucks are supplied to the Russian army and the armies of friendly countries, which already indicates the highest quality of products. As part of expanding the range, the plant recently launched the production of two models of modern sludge pumps based on KamAZ trucks, with tanks with a volume of 8 and 15 m3.

The operator controls the filling of the tank and supply of the hose remotely, from a remote control panel. The tank is unloaded by raising the tank at an angle of 60°. The compressor module is equipped with Italian equipment - a Jurop PR-150 hydraulic vacuum compressor and a Udor GC50/12 high-pressure water pump, as well as a hydraulic tank and an oil separator.

"Imported" competitors

Specialized sludge sucking machines are supplied to our market by the well-known German company Kroll Fahrzeugbau-Umwelttechnik GmbH. Kroll sludge suckers are sold by the official representative of the company - Moscow.

To eliminate sludge deposits, clean sedimentation tanks and wells, Kroll offers a model that is based on the Man or Mercedes chassis. The tank capacity is 18 m3, there is also a capacity of about 1 m3 for clean water. However, the manufacturer is ready to fulfill any customer wishes, and the volume of the tank may be different.

The suction pump uses a vacuum pump with a capacity of 3000 m3/h. When unloading, the back cover opens upward using a hydraulic cylinder and is locked in the transport state with a pneumatically controlled central lock. Unloading occurs by gravity, due to the tilting of the tank by the hydraulic cylinder rod. At the buyer's request, Kroll can also install a pneumatic piston unloading system.

In addition, Kroll offers a lot of additional equipment and various systems. This includes a system for draining residual water, a tray with tools, a water level alarm, additional hoses, as well as a spray gun for washing away deposits, the machine pump creates a jet pressure of up to 150 MPa, etc.

The Western market offers a wide range of sewer cleaning machines. These are mainly combined machines, since their use is much cheaper than the use of specialized sludge sucking and sewer washing machines for the same work. However, for large volumes of work, a “division of labor” may be necessary. The Kaiser Aquastar suction machine is an extremely versatile municipal equipment.

The machine from the Austrian company Kaiser is sold in Russia by PSM-Techno LLC from Krasnodar. Kaiser Aquastar is equipped with a Kaiser vacuum pump with a capacity of 3100 m3/h. Using the KWP system, the pump performance can be doubled, up to 6200 m3/h.

Kaiser's remote control system operates within a range of 50 to 120 m, depending on the surrounding terrain. When the driver moves out of communication range, all controls are locked. Communication between the transmitter and digital receiver is carried out without interference from random radio signals. The hose winding and unwinding control is pneumatic. The control panel is equipped with a battery, the capacity of which is sufficient for at least 2 work shifts of continuous operation, and charging can be done either from a 220 V network or directly from the on-board network of the machine.

Although Kaiser Aquastar is positioned as a sludge sucker, it has very wide capabilities. Thanks to the selection of different fence booms, the machine can be used equally effectively for many tasks.

The installed high-pressure pump supplies water with a capacity of up to 30 m3/h or, optionally, up to 50 m3/h and creates a pressure of 20.26 MPa. The Rotomax system allows water to be reused in the cleaning system, which is why Kaiser machines are called the environmental standard for sewer cleaning machines. A dry-type vacuum device allows these machines to be used even when cleaning streets.

But perhaps the most popular among foreign suppliers of sewer cleaning machines in Russia today are machines from the Italian company MORO. The quality and popularity of MORO products is explained by the vast experience of the company, which has been developing vacuum equipment since 1955, and in general the birth of MORO dates back to 1882. The acquisition of Johnston Sweeper technology in 1972 allowed MORO to raise the production of municipal machines to a whole new level.

MORO's representative in Russia - Moscow - has the ability to quickly supply not only excellent sludge-suction machines from this manufacturer, but also sewer-washing machines, MORO vacuum loaders, as well as combined sewer-washing and sludge-suction machines, the use of which is very common in Europe.

The modern design of the new model range of MORO machines designed for the maintenance of sewer and utility networks attracts the attention of not only specialists, but also ordinary people. The reverent attitude of Italians to the appearance of everything that surrounds them is widely known, but in this case, in addition to the aesthetic component, the design of MORO special equipment is determined by the technical and operational requirements for this type of equipment.

The aesthetics and high level of the manufacturer can be seen in the names of the series of machines: these are Colibri - compact combined sewer washing machines with a total weight of only 3.5 tons; Elegance is the most popular series of sludge sucking and sewer cleaning machines (weighing from 12 to 18 tons). Sewer cleaning machines with increased productivity weighing from 25 to 32 tons can be immediately identified by their formidable name - Tornado. The MORO model range is extensive - there are 34 basic models, but at the request of the client, you can assemble a machine to perform any tasks necessary for him according to individual technical specifications. According to the tradition of the MORO concern, the material used for the manufacture of tanks is AISI 304 stainless steel. The sludge compartment for different models holds from 1200 l (Colibri) to 14,000 l (Tornado). The system of compartments for clean water is arranged as follows: the main tank with a capacity of 600 to 7000 liters is located in the front part, and additional polyethylene tanks are located on the sides of the tank.

The characteristics of MORO sewer cleaning machines are such that you can choose a model that will help you in any specific conditions and for any volume of work.

Elegance series machines are equipped, as a rule, with two pumps: a vacuum and a high-pressure pump, creating a pressure in the system of 240 bar, protected by special hatches from the adverse effects of the environment, but not impeding access and maintenance. All MORO machines are equipped with stainless steel drums with automatic closers for 3/4″ and 1/2″ high pressure hoses. Special pencil cases built into the body are designed for storing sleeves. An upper hydraulic telescopic boom with a rotation angle of 360° is designed for the suction hoses. Taking into account the specifics of the work being carried out, an electric winch was installed on the vehicle to lift road hatches.

Experts will appreciate the availability of a number of systems in MORO machines, such as pneumatic drainage of water from water lines, heating of water with an autonomous WEBASTO diesel burner, and water circulation in the system. In the machine control system, everything is thought out to the smallest detail, ergonomic and functional, which makes the operator’s work efficient and accurate. For the convenience of the operator, the possibility of remote control is provided using a multifunctional radio remote control. Everything is thought out for maximum productivity. In terms of price-quality ratio, combined sewer washing machines produced by MORO are the best offer on the market today.
