The main advantages of centrifugal pumps are efficiency, ease of use and long service life. There are several varieties of such aggregates. If you wish, today you can also purchase equipment such as a centrifugal pump for dirty water. Such models can be used for pumping wells, pits, treatment biostations, etc.
Centrifugal pump
The advantages of this type of equipment, among other things, include the simplicity of the design. Such pumps consist of a sturdy casing and disks with blades located in it. Hoses or pipes are connected to the unit through nozzles.
The principle of operation of this type of equipment is quite simple. When the impeller rotates, the water in the casing is displaced from the center to the peripheral areas. As a result, increased pressure is created, and the liquid begins to be squeezed out into the pipeline.
Types of Centrifugal Pumps
Among other things, the advantage of this modern equipment is that it can be used to work with any liquids (including oils). However, most often, such models are still purchased by the owners of suburban areas. The popularity of this equipment is explained primarily by its low cost and reliability. Centrifugal pumps of the following varieties can be used in country houses:
downhole;
well;
drainage;
fecal.
The first type of pump is included in the water supply scheme of country houses and in most cases can be used to pump only clean water. If there is too much sand in the well, the impeller of the unit will clog, which will lead to engine failure. Centrifugal units can also be classified into conventional and self-priming. The latter variety gives more pressure.
Centrifugal pump for dirty water: design features
Units of this design are usually quite high power. Therefore, they can be used for pumping not only clean, but also dirty water with a certain amount of suspended particles (from basements, pools, etc.). Such centrifugal pumps are called drainage pumps. A feature of their design is that they can pass through themselves, without harm to nodes and mechanisms, rather large particles of dirt - up to 5 mm in diameter.
Fecal pumps
Equipment of this kind is also used for pumping dirty wastewater, but in sewer systems. Such units can be used, for example, in cases where treatment plants are located very far from home. It is also advisable to use a fecal centrifugal pump for dirty water when plumbing equipment is located at a great distance from the riser or below it.
Types of centrifugal fecal and drainage pumps at the installation site
In addition to the scope of use, units of this variety can be classified by the method of water intake. In this regard, the models are distinguished:
Submersible centrifugal pump for dirty water (drainage) is installed directly in the pond or pool. Surface models are mounted next to them.
Dirty wells: expert advice
For pumping such mines, experts recommend using conventional units designed for clean water. But only domestic production. It is known that it is necessary to pump out dirty water from a well in two cases:
Domestic downhole models are not as sensitive to the presence of sand and mud in water as imported ones. Therefore, to pump dirty water from the mine, experts usually advise in addition to powerful imported equipment to purchase a small submersible pump of Russian or Chinese manufacture. Such equipment usually costs only around 1500-1700 rubles.
Of course, you cannot use low-power pumps to provide watering or water supply at home. For short-term pumping, they are just perfect. Subsequently, such equipment can be adapted, for example, for cleaning a hydraulic tank.
The use of drainage pumps in dirty mines
Units of this type can also be used for cleaning silted wells. However, pumping very shallow mines is in most cases all that drainage centrifugal pumps are capable of . For a well (for dirty water) such equipment is rarely used. The fact is that the diameter of the casing of submersible drainage pumps is often quite large. Such equipment simply will not pass into the mine. Surface household models are allowed to be used to raise water from a maximum of 8-10 m.
Conventional and self-priming centrifugal pumps for dirty water (drainage) are most often used to clean sources such as wells. In this case, both a submersible and a surface model can be used.
Reviews about foreign manufacturers
Grundfos is rightly considered the highest quality brand of drainage and fecal centrifugal (as well as borehole) units in our country. Owners of suburban areas about the models of this manufacturer have developed a good opinion mainly due to their compactness, light weight and ease of use.
Pedrollo is another imported brand of drainage pumps that has earned good customer reviews. The pumps of this manufacturer are characterized by a high degree of reliability and the ability to pump even the dirtiest water without harming themselves.
Reviews about Russian models
The main disadvantage of the Grundfos and Pedrollo models is the Russian owners of suburban areas consider the high cost. The price of domestic and Chinese centrifugal drainage units with approximately the same characteristics can be two times lower. According to many owners of country houses, the most reliable brands of Russian budget drainage pumps are:
- "Gileks pitching" 550/14. This submersible centrifugal pump for dirty water is produced (photos of structures of this type are presented on the page) by the same company as the Vodomet well models, well known to Russian summer residents. Its main advantages include high power, the ability to use for pumping water from pits and wells, as well as septic tanks, low noise.
- PRORAB. Pumps of this manufacturer can pump over 12 thousand liters of dirty water per hour. Consumers also relate to the advantages of Prorab aggregates ease of maintenance and small size.
- "Vortex". Another domestic brand, deservedly enjoying popularity among owners of country houses. Models of this manufacturer are very inexpensive, they are distinguished by high power and low noise.
- For the treatment of industrial effluents and in urban sewer systems, similar in design, but much more powerful equipment of this type is used. An example is the centrifugal pump for dirty water CM80-50-200. This fecal aggregate is manufactured by Livhydromash. It can be disassembled without disconnecting the pipelines.
Thus, the choice of equipment such as a centrifugal pump for dirty water depends primarily on where it is supposed to be used, as well as on the financial capabilities of the owners of a suburban area. Of course, when buying such equipment it is important to pay attention to its brand. Of course, you should not buy an aggregate from an unknown manufacturer.
