• rural irrigation;
• pumping waste from different systems and electrical engineering;
• neutralization of the consequences of accidents.

The design of the pumps "Gnome" is made of two parts - pump and motor department, which are harmoniously combined into one unit. The engine is cooled directly when pumping fluid, and its seal on the shaft is provided by the end seal. Inside is filled with oil, which cools and lubricates the bearings of the device, ensuring their full working condition.

It must be remembered that immediately before switching on the unit must be in the liquid at a level of at least 50 cm. After starting the device, the pumped out fluid is sucked through the additional mesh into the inside of the case, from where it is pushed out of the pump compartment under pressure.

All Gnome pumps are available in four varieties:

• Household. Submersible device, which is characterized by an average level of power and performance. Mainly used at home for pumping dirty water. Their productivity does not exceed 10-25 m3 / hour.
• High pressure. They belong to the category of industrial machinery, as they differ in impressive performance, which can reach 50 m3 / hour. The power of such models is up to 45 kW.
• Explosion proof. Professional devices that are marked with the EX marking. Actively used in industrial production and large objects. In comparison with a mud copy, it is characterized by higher cost and power.
• Self-cooled. Used not only for full, but also for partial immersion. Such a drainage unit is equipped with a special cooling jacket, which is responsible for the level of cooling in the process of pumping out dirt or other aqueous liquid. Technical characteristics of this device allow to operate it in those places where there is no possibility to immerse the product in water.

It is worth noting that all types of pumps "Dwarf" are very simple and quick disassembly of the main components. This feature makes the process of cleaning and repair as easy and affordable as possible. In the bearing shield there is a special plug in which the oil is poured. The manufacturer recommends careful monitoring of the quality and level of oil used, since the full functionality of these mechanisms depends on this. Its timely topping up and replacement will allow the device to maintain its excellent working condition during the entire period of operation.

Devices that can be operated not only separately, but also in conjunction with other units, are pumps "Gnome" 25/20. They are a portable system of the submersible type with the presence of an electric motor. The tightness of the internal part of the electric motor is ensured by the assembly on which the mechanical seal is located. Such models are used for pumping groundwater, drainage of ditches, swamps, basements, as well as are an integral technique at construction sites and hazardous production.

The vibration type of the “Gnome” pumps remains quite relevant. In relation to other options, such devices are considered to be much more economical in terms of energy consumption and are distinguished by affordable pricing policies. Their range allows you to choose the best option that will best meet the requirements.

The fecal type of pumps “Dwarf” is in wide demand, which is used not only for pumping fecal effluents, but also for irrigation in agriculture or for pumping water from pools. These units are characterized by increased resistance to negative impact factors and perfectly retain their original qualities throughout the entire period of operation.

Pumping water mixtures with high density of solid particles, the level of which is about 2500 kg / m3, is capable of providing a “Gnome” slurry pump. Technical characteristics of these models fully contribute to this.

Pumps "Gnome" are represented on the world market in the form of monoblocks, consisting of two parts: an electric motor and a pump part. The unit is driven by a starting device, which is located on the cord. For maximum convenience, the Gnome products are equipped with special capacitors and circuit breakers that serve as protection against engine overheating. Immediately before turning on the device, it is completely or partially immersed in water. Without water it is allowed to operate the unit no more than 15 minutes.

When preparing the “Dwarf” pump for operation, it is necessary to inspect the device for the presence of body damage.that may occur not only on the case, but also on the power cable. Be sure to check the presence of oil in the appropriate chamber. After that, you need to remove the cap from the nozzle, connect the device to a flexible hose, which is fixed on both sides with special clamps.The size of the hose is chosen individually for each model of the pump, taking into account the parameters of its discharge port.

In the process of immersion of the pump “Dwarf” with the help of a cable into the pit, it must have an exclusively vertical position with a tolerance of no more than 10 degrees. It is necessary to provide a full discharge from the hose, preventing the appearance of bends and fractures on it. Installing the unit on a sandy or muddy bottom, it is necessary to lay the substrate in the form of a rubberized mat at the installation site. Such a measure will allow you to create a stable and anti-slip base on the installation of the device. After adjustment of the pump and compliance with all rules of operation, you can start.

It should be noted that all types of Gnome pumps are easily repaired due to the simplicity of their design.

The main causes of problems and their solutions are:
