For the convenience of clients, we have prepared a questionnaire form for the production of CNS for filling out and sending to us.
KNS performance
The capacity of pumping stations can range from 0.1 to 20,000 m3.
We offer not only high-capacity sewage pumping stations, but also low-capacity sewage pumping stations for use in health centers and hypermarkets. The advantages of such solutions are compactness, installation indoors and outdoors, long trouble-free operation, unlike the Sololift wastewater pumping system and similar ones.
KNS device
A complete sewage pumping station consists of a housing, pumps, a set of pipes and pipeline fittings, a waste removal mechanism, liquid level control devices, and a control cabinet.
KNS building
Depending on the location conditions and performance of the pump station, the size of the pump station body can be in diameter from 0.7 m to 8 m.
Material of manufacture of the KNS body:
. polypropylene and polyethylene sheets;
. corrugated and spiral polypropylene and polyethylene;
. fiberglass.
Each material from which the body of a sewer pumping station is made has its own characteristics, and these characteristics must be taken into account when designing and constructing utility networks.
The main advantages of KNS housings made of sheet plastic:
. low cost;
. possibility of manufacturing any shapes and sizes;
. possibility of local production;
. a light weight;
. high service life.
The main advantages of KNS housings made of polyethylene spiral pipes:

. ease of installation.
KNS pumps
Sewage pumps are selected depending on the required flow rate and performance, taking into account possible resistance to the final point of waste discharge. Basically, submersible pumps are installed with a device for quick lifting along rods for repair and maintenance. Lifting sewer pumps does not require a person to descend into the sewer pumping station.
In the sewage pumping stations we produce, we install time-tested pumps from leading global manufacturers:
Wilo
Grundfos
KSB
Basically, in complete sewage pumping stations, from 1 to 3 pumps are installed (working pump, backup pump, storage pump).
KNS control cabinet
The control cabinet in the sewage pumping station performs the following functions:
. manual or automatic switching of pumps;
. programming the installation of power indicators of pumping units, liquid levels, etc.;
. fault notification;
. changing the operation of the main pump to a backup one
. switching the order of operation of pumps for equal resource production;
. programmable switching between main and backup pumps;
. monitoring the current of each pump motor;
. engine overheat protection;
. remote shutdown;
. work with external alarm sources, obtain work data.
Shut-off valves and pipelines of KNS
KNS shut-off valves are mainly gate valves, taps and check valves. Typically, each pump is equipped with a gate valve and a check valve. In order to avoid breakdowns and subsequent labor-intensive dismantling and installation inside the pumping station body, we install high-quality, proven fittings in our pumping station.
Pipelines are made of materials that are not subject to corrosion - plastic and high-grade stainless steel.
Operating principle of the CNS
The waste liquid flows through a gravity collector through a device for removing large debris (basket, automatic screen, etc.), where waste that is unacceptable in size for pumping is removed into the receiving tank of the pumping station housing. When the level rises, the first pump is turned on, if the level rises further, the second pump is connected, and if the level continues to rise, the third pump is connected (if it is included in the package). In normal mode, the pumps are turned on alternately to ensure uniform service life.
KNS can be completed various devices, improving their operation, for example, a sludge agitation system, lifting mechanisms, sound alarm devices, remote data transmission devices, etc.
Additionally
Our company carries out such work as repair and replacement of equipment, modernization and commissioning at existing stations.

Production of complete and fully prefabricated sewage pumping stations in housings made of durable reinforced fiberglass
SPS is a complex of hydraulic structures and sewerage equipment designed for lifting and pumping waste, fecal, industrial, ground and other waters.
| new! | |||
Sewage pumping stations are installed for the purpose of pumping domestic wastewater. The design of the pump station may differ slightly, but general form pumping stations are similar. This is a hermetically sealed container into which they drain by gravity. wastewater. A fecal pump is additionally connected to it, through which wastewater is pumped to another pumping station or to a place for biological treatment water. A modern CNS station operates completely autonomously.
The equipment is supplied complete, so the installation process is greatly simplified.
The price of a pump pump, as well as the choice of its size and technical parameters of pumping equipment depend on:
- volume of pumped wastewater;
- their lifting heights;
- diameter and length of the pressure sector;
- depth of placement of the supply sector.
Production of pumping stations
The FloTenk company produces SOPs using the machine winding method, which can be radial or cross. In addition to this, to distinctive features It is worth mentioning the presence of an insulated hatch, an internal pressure pipeline with control valves, a spherical bottom, a fiberglass ladder and a folding platform for servicing the station. In other words, you can order a complete high-quality pump station from our company.
Advantageous features of CNS
- Significant space savings for placing a pumping station. There is no need to order reinforced concrete containers with ventilation. Compared to old 12-meter structures, modern pumping stations are manufactured with a diameter of 1.5 meters.
- An excellent energy saving option. When operating such a pumping station, a constant pressure is ensured, while energy consumption is reduced several times.
- Maintenance of a pumping station does not require much expenditure, and this concerns not only money, but also effort. At emergency situations the dispatcher immediately receives the signal. The cost of CNS is quite reasonable, so you can save on this parameter.
How does CNS work?
First, the effluent through the pipeline from the septic tank enters the lower compartment of the station. When the pumping station is operating, the valves on the pipeline remain open. Each pipe has its own check valve, which prevents waste from entering the pump again.
The operation of the pumping station is carried out without the release of unpleasant odors in environment. This feature is ensured by the presence of a hermetically sealed hatch. This structural element is located at the top of the pumping station. Some equipment models are equipped with ventilation pipes to ensure air exchange.
The SPS is controlled using float sensors. If they are triggered, then on the remote control automatic control The corresponding LEDs light up. Some equipment models provide for notification of the dispatcher via a phone call or SMS.
All KNS pumping stations are equipped with an electronic control panel, which is located in the technical room or on metal stands located on the surface.
Design of pump station
When ordering sewage pumping stations of a certain type and quantity, you need to familiarize yourself with the features of the site’s landscape. You also need to answer performance questions:
- in what mode the equipment should operate;
- what volume and type of wastewater will be pumped.
An important parameter is the performance of the pumping station and the availability of additional equipment to improve the quality of service of the unit.
SPS for domestic wastewater must be selected very carefully, since incorrect selection of pumping units affects the reduction in the operating life and productivity of SPS.
Complete sewer pumping stations can be equipped with the following elements:
- float switch that automatically operates when the container is filled or emptied;
- pumps with automatic redundant activation, in this case the operator receives a corresponding signal;
- working and spare pumps, which are activated by separate float switches. If one pump fails, the backup unit is automatically activated.
Sewage pumping stations (SPS) are also equipped with devices that record water consumption.
Operation of pumping stations (PS)
It is important that the KNS sewerage station is installed correctly, since its service life depends on this. Flotenk specialists will help not only design underground structure, but also install it taking into account all the requirements and rules.
Installation of pumping equipment is carried out only according to the strict recommendations of the manufacturer, therefore, when working independently, it is important to act in accordance with the installation manual.
If there is a need to install a good sewerage station, then it is recommended to buy it at the KNS production facility in the Flotenk company, which guarantees the high quality of its products. In addition, it is possible to separately purchase pumps for pumping stations for a particular station model.
KNS - sewage pumping stations produced by NPO Industrial Water Treatment. Their purpose of operation is to pump out domestic, stormwater or industrial liquid waste when independent outflow is impossible. Due to its high productivity, the sewer station can pump from 1 to 10,000 cubic meters per hour. Pumping water is possible in any conditions. SPS are suitable for use in private houses with an individual sewerage system, or for large residential areas, as well as for use on the scale of large industrial organizations or small businesses.
Sewage pumping station: internal technical structure
The design of the SPS is the following device: the so-called working body (a certain container) inside which specialized equipment is placed:
Submersible pumps;
Internal pipeline;
Shut-off valves;
Pipes.
The body of the sewage pumping station must be made of high-strength, completely inert materials (due to the presence of highly aggressive environments inside the sewage pumping station).
Since the KNS assumes remote control, during its installation a control cabinet must also be installed, in which a set of necessary automation is located. Such a control cabinet can be placed for operation outside (climatic version) or inside technical rooms (indoor version).
Will your pumping station last? Its service life is not eternal, but its duration depends on two factors:
Quality of materials of the working body;
Quality of components.
NPO Industrial Water Treatment is a Russian leader in the industry of production of water purification equipment. The company cooperates with the world leader in the supply of equipment for pumping stations, automation and control cabinets - the manufacturer Grundfos.
The quality of engineering technologies, combined with the high strength and corrosion resistance characteristics of sewer pumping station casings, guarantees unrivaled long-term operation of sewage pumping stations. The manufacturer provides a guarantee for the equipment sold:
Warranty for pumping stations – 5 years;
The warranty on pumping equipment is 3 years.
Complete pumping stations have the possibility of lack of human control. Such CNSs operate completely in automatic mode.
The Scientific and Production Association “Industrial Water Treatment” offers a colossal range of pumping stations for operation in any conditions. You can buy a water treatment system with a guarantee from a leading manufacturer of water treatment systems in our company. We offer competitive prices and convenient delivery.
The wishes of each of our customers are important to us, and therefore we can offer a standard pumping station produced by Grundfos, or unique system water treatment of our own production, taking into account all individual wishes and features. Each station is manufactured at the factory to order, and the design of the pumping station is agreed upon with the customer at the design stage.
Tanks for pumping stations from the manufacturer
Gravity sewer networks are more economical, but their installation is not possible at all sites. In such cases, systems with forced discharge are installed, equipped with sewage pumping stations.
Manufacturers of pumping equipment offer ready-made solutions, but a typical pumping station is not always able to fully cope with the tasks facing it at a specific facility. In such cases, a CPS station is designed to order.
The Eurolos company produces reliable plastic containers for pumping stations of all types. You can order any container from us, regardless of its volume or complexity. We manufacture both standard products and tanks for pumping stations based on the customer’s individual project.
We produce plastic containers for sewerage from monolithic sheet polypropylene. Welding is carried out on automatic machines, as well as using professional Liester manual equipment. Modern equipment allows us to obtain high-quality seams, guarantee the strength of welded joints and absolute tightness of the entire container.
Advantages
Sewage pumping stations are used to drain stormwater and wastewater, as well as transport wastewater to treatment plants in networks with forced discharge. Sewage systems with sewage pumping stations have advantages over gravity networks:
- High system reliability, minimizing the risk of soil contamination and groundwater;
- Reducing the cost of transporting wastewater to treatment plants;
- Simplifying the maintenance of the sewer network, saving on the services of sewer trucks.
A sewage pumping station can be installed on new utilities, designing it in accordance with the features of the facility. They are also suitable for the repair and modernization of old utility networks that have reached the end of their service life or have become ineffective.
Structurally, a pumping station is a cylindrical container, horizontal or vertical, inside which all the necessary equipment is placed: pumps, pipelines, fittings, etc. For control, the station is equipped with an automatic cabinet. The housing can be made of various materials.
The Eurolos company offers polypropylene tanks for sewage, as this material has a number of advantages over HDPE, stainless steel, and traditional reinforced concrete. The advantages of polypropylene containers for pumping stations are:
- Resistance to corrosion and rotting;
- High strength;
- Good thermal insulation;
- Light weight;
- Long service life.
A polypropylene sewer container can serve for 50 years or more, reliably protecting moisture-sensitive pumping equipment, providing the conditions necessary for its normal operation. Inside the polypropylene casing, you can place additional elements to facilitate station maintenance (stairs, lifts, platforms, walkways, etc.).
Installation of pump pump stations is mainly carried out in a pit, so the most stringent requirements are imposed on the strength of the casing. Plastic containers made of sheet polypropylene fully meet all necessary standards and easily withstand soil pressure. To install SPS in areas with high static and dynamic loads, for example, under roads, containers with a reinforced body and additional stiffeners are manufactured.
The introduction of plastic containers for pumping stations made it possible to abandon large concrete and metal structures. For comparison, the KNS polypropylene pumping station, with similar performance, has a smaller diameter compared to traditional tanks made of reinforced concrete rings.
The low weight of polypropylene water pumping station tanks facilitates their transportation and installation. However, to prevent squeezing out by ground or flood waters, anchoring is mandatory. Those. After the sewage pumping station is finally installed in its place, it is securely fastened with anchor bolts in reinforced concrete slab base.
Typical pump stations
Depending on the purpose and tasks to be solved, the following types of sewage pumping stations are distinguished:
Drainage
Used in drainage systems to drain excess groundwater on the site.
Stormwater
Login to systems storm sewer and serve to drain rain and melt water.
Sewage
Designed for the removal of domestic and black wastewater.
Production
Installed on industrial facilities for transportation of highly polluted industrial wastewater to treatment plants.
In some cases, complex solutions can be developed, but this approach to the arrangement of sewer networks is not always advisable.
Principle of operation
Sewage pumping stations are designed in such a way as to minimize human intervention in their operation, as well as to minimize the time workers spend inside the tank. The operation of the pumping station is controlled automatically. Sensor signals are displayed on the control panel, which allows you to monitor the operation of the system and promptly intervene in it in the event of an emergency.
Wastewater enters the pumping station through a supply pipeline. Their further pumping and transportation is provided by pumps installed in the lower part of the station. The number and performance of pumps is calculated individually. In typical projects, as a rule, main and backup are used submersible pumps with the required power. The pipes have check valves to prevent waste from flowing back into the pump. Transportation of wastewater is carried out through a discharge pipeline.
The body of the KNS tank is closed with a tight, hermetically sealed hatch, which prevents the appearance of unpleasant odors at the installation site. To ensure air exchange, a ventilation pipe is installed in the upper part of the housing.
Production of pumping stations
At the Eurolos company you can buy a reliable and durable tank for the KNS pumping station. We are a manufacturer of polypropylene containers for sewer networks and can offer our clients the implementation of solutions of any complexity at an affordable price.
Custom-made tanks for pumping stations will allow you to create a system that fully meets the needs of the facility. Ready standard projects, despite their diversity, are almost always a compromise. By ordering a container from our company, you will not have to make a difficult choice and look for a suitable option.
Two main types of Sewage Pumping Stations (abbreviated as SPS):
1. Complete (modular) sewage pumping station (SPS)
is a system assembled in a single housing and equipped with all the necessary devices and equipment. It looks like a large vertical barrel or vertical tank. Modular pump stations most popular today. Today they are used almost everywhere. This is due to the significant speed of installation and commissioning and large savings compared to constructed construction pumping stations. About this view KNS we'll talk about it below.
2. Sump station as a free-standing building structure
- this is a separate structure of a special configuration that performs the task of pumping wastewater to the required distances. As a rule, the pumping station pumps wastewater to treatment facilities, or to the next section of the pumping station. The body of such pumping stations is made of standard general construction materials - brick, concrete, finishing and building equipment - steel. The design differences from the modular (complete) pump station are significant. There are no fundamental differences in operation and functionality. For this type of pumping station, our company offers reconstruction of the pumping system, shut-off valves, automation and protection of pumps, monitoring and dispatching of the entire pumping station.
Materials used for the manufacture of the case
modular complete Sewage Pumping Station (SPS)
Fiberglass composite
fiberglass reinforced polyester fiberglass
Fiberglass– a composite material consisting of glass filler and a synthetic polymer binder. The filler is mainly glass fibers in the form of threads, strands (rovings), fabrics, mats, chopped fibers, and the binder is mainly polyester, vinyl ester and epoxy resins. Just as steel reinforcement gives high strength to concrete in building structures, and fiberglass increases the strength of the resin of the plastic material. Thus, glass fillers give strength to fiberglass, and resins bind the fibers of glass fillers to each other and impart tightness to the structure and mainly determine its properties. Fiberglass, like other composite materials, has been developed and used for a long time.
Fiberglass products are a worthy alternative to metal. Fiberglass is much cheaper than metal, does not rust, can withstand any temperature, does not crack in the sun and does not change shape. Some structures that meet special technical requirements can only be constructed from fiberglass. Products made of fiberglass have become widespread in areas associated with extreme operating conditions: aircraft, rocket and space technology, shipbuilding, petrochemical industry, etc.
The advantages of using products based on chemically resistant fiberglass include:
- high resistance to aggressive environments and increased service life,
- significant reduction in product weight (fiberglass density 1.7-1.8 g/cc), which is important for transport containers,
- high specific strength,
- high specific impact strength,
- fire resistance,
- low operating costs and ease of maintenance,
- possibility of on-site repairs (without dismantling),
- wide possibilities for product configuration.
Production of fiberglass products
|
An important advantage of fiberglass production technology is the short cycle of mastering and preparing production, which is two weeks. The technology for the production of fiberglass products makes it possible to produce structures of any complexity, which means that a fiberglass plant can begin production of any structures in a short time. Fiberglass plastics are produced various methods, such as: impregnation, winding, drawing and direct pressing. In the manufacture of composite products the following is used: |
For reference:
Data on fiberglass taken from the official website of the FloTenk company!
Polyethylene (HDPE) KNS
Polyethylene (HDPE) is a high-quality product, which is used, among other things, for the production of oil and food containers. The material is frost- and shock-resistant. UV resistant. The wall structure is stronger than when using polypropylene. This technology has proven itself well in the market of polymer KNS. The strength of the structure is sufficient to bury the container to a significant depth of the well.
Polypropylene KNS
The material of the products is polypropylene, which allows the containers to be frost- and shock-resistant. The material is UV resistant. The strength of the structure is not high enough, so for deeply buried containers it is recommended to strengthen the walls with longitudinal or transverse stiffening ribs.
There were complaints from users about the divergence of the seams of the structure after 3-4 years of operation. The data on complaints suggests a question of the quality of the material, or the quality of the workmanship. assembly work. However, negative experiences must be taken into account!
Steel pump stations are mainly developed industrial enterprises related to metallurgy. A high-quality manufacturer uses carbon steel with a double anti-corrosion coating (ZINOTANE + POLYTON-UR, ZINOTANE + FERROTANE). They are also made to order from stainless steel.
Depending on the location where the tanks are used, there are also different production features: tanks are made of St3 steel for use in temperate climates and of 09G2S steel for northern regions.
If it is still chosen steel, then you should only choose high-quality metal with a multi-layer anti-corrosion coating to protect the container from corrosion. IN otherwise choose fiberglass or polypropylene KNS.
Concrete pump station
economy option
Concrete pump stations do not have a strictly designated production group. They are a hybrid economy version of the production of a modular pumping station. On the one hand, this is no longer a modular complete pumping station, and on the other hand, it is not yet an industrial construction-type pumping station. There are a number of inconveniences and difficulties with this type of CNS:
- It is not possible to immediately install and test all equipment in production
- Specialists for each type of production need to be kept on the construction site - this increases the cost
- The tightness of SPS made of concrete rings is always lower than its modular counterparts
- Unfortunately, the quality of concrete does not always correspond to what is declared.
- When installing equipment inside, technical difficulties arise, since all work has to be done in a deep vertical pipe (it is necessary to organize an air flow into the container with working specialists, etc.)
- The installation of a concrete pumping station is not economical due to the above-mentioned difficulties
The production of concrete pumping stations can be chosen only if other analogues are not suitable for some reason!
