Drainage pumps are in demand because they allow you to raise clean water from wells to the surface and pump out dirty liquids. They are popular among Russian consumers, due to the versatility of use. The brand of drainage pumps Gnome has received many flattering reviews even from experts in this field.
Device and principle of operation
A gnome is a submersible pumping station, which is most often used to pump dirty water from tanks, ponds, etc. The market has a wide range of models with different configurations. There are units designed to work with cold and hot liquids, models with different electric motors.
The design of the electric pumps is a monoblock, which includes two important parts: an electric motor and a pumping station.
Parts of the pumping station:
- housing;
- Working wheel;
- challenge.
For pumping water with a high concentration of solid impurities, as well as clay or cement suspension, a filter mesh is installed in the lower part of the unit body.
Gnome drain pumps are equipped with an asynchronous type electric motor with a stator, a cover, a rotor and a bearing system. The engine cavity is filled with oil, which provides high-quality lubrication and cooling of rotating parts.
The upper part of the casing is equipped with a rubber cuff of high elasticity, which compensates for the expansion of the cooling medium in case of overheating of the installation. The motor itself is cooled during the pumping of water by the water itself.
The rotor speed for all Gnome models is 3000 rpm. The stator is equipped with built-in thermal fuses that automatically turn off the station in case of overheating. It is recommended to disconnect it from the power supply until it cools completely.
The start-up of the equipment is carried out by the launching apparatus, which is located on the power cord. Also, the unit is additionally equipped with a capacitor and an automatic machine, which automatically switches off the pump when overloaded.
Before starting, immerse the unit in liquid. The idle time should not exceed 15 minutes.
The principle of operation is based on centrifugal force, which is formed when the impeller rotates.
Application area
A dirty submersible drainage pump is the most common type of pumping equipment. It is used for pumping liquids with a low concentration of solid particles.
Like other types of submersible pumps, the Gnome is used in all industries and for domestic purposes for pumping and cleaning:
- industrial fluids;
- water from swampy or contaminated water bodies;
- domestic wastewater with the exception of fecal matter (due to technical limitations, the equipment is not intended for pumping liquids with a high concentration of dense impurities);
- groundwater.
Pumping drainage station is widely used in the following areas of human activity:
- in personal plots;
- at utilities;
- in rural industry.
In order for the equipment to realize its tasks, it is necessary to choose the right pump based on the required criteria.
Types of pumps and their technical characteristics
The production of submersible pumps Gnome is engaged in three Russian production and one Belarusian. The highest quality is equipment manufactured at the Odintsovo Pumping Plant.It is characterized by high build quality and materials used, low concentration of marriage. The disadvantages of the products include only a high cost in comparison with analogues and expensive repairs, replacement of parts.
Models are divided into four large groups:
- Domestic pumping stations used for pumping water on household plots or private homes. If you need equipment for water supply and sewerage in a country house, you need to choose a model from this group.
- Powerful units that are used in utilities, construction and industry. Performance indicators reach 600 m3 / h. control the equipment using the control panel, which is purchased separately or installed during installation.
- Explosion-proof equipment is used in the oil and refining industries, energy and chemical enterprises. The price of such models is very high.
- Self-cooled pumps are used for full and partial immersion in water. A feature of the group is the design characteristics of the case, they are called "cooling shirt".
The most common models are Gnome 10/10 and Gnome 10 / 10J. They are designed for work in cottages, country houses, in the field of private construction. Work from a single-phase network.
Gnome 10 / 10_380
The model is a mud-water monoblock single-stage pump. Designed for pumping clean or contaminated liquids with a maximum size of solid impurities of 10 mm, a concentration of not more than 1.1 t / m3.
It works with liquids whose temperature does not exceed 40 degrees. The system is mobile, which is an advantage. Models are equipped with a handle for transportation.
Specifications:
- The impeller, housing and flow part are made of aluminum.
- The motor is asynchronous, there is a built-in thermal protection.
- E - protection class, degree of IP X8.
- 220 W models are equipped with a float switch.
- The length of the network cable is 10 m.
- There is a double shaft seal on the end of the pump station.
- The maximum water supply is 16 cubic meters per hour.
- The weight of the pumping station is 11.5 kg.
- The pressure at the outlet is 50 m3 / h.
The cost in the Russian market starts at 7,000 rubles. In order not to purchase a fake of dubious quality, you need to contact official representatives or large specialized stores.
When making a purchase, it is important to check the availability of a passport and operating instructions, as well as a standard warranty card with a detailed description of the characteristics.
Advantages and disadvantages of Gnome submersible pumps in comparison with analogues
The gnome is in great demand among domestic consumers, because it combines high quality, power and performance with an acceptable cost. But the advantages of submersible pumps do not end there:
- The unit is equipped with a cleaning filter, which significantly extends the life of the device. As it becomes dirty, it can be removed and cleaned.
- A high degree of maintainability, as well as the ability to purchase the necessary spare parts at an affordable price.
- A wide range of products that allows you to purchase a model of the desired configuration.
- The device is equipped with a circuit breaker that protects the entire mechanism from overload and short circuit. Due to this design feature, the owner does not need to regularly monitor the operation of the unit.
- The user has the opportunity to refuse to install check valves or valves.
- Ease of use, installation and regular maintenance. To work with an electric water station, special knowledge is not required.
If you use the drainage pumps Gnome exclusively for pumping contaminated water, such equipment has practically no analogues.
