Whirlwind drainage pumps: design features and range overview

Drainage pumps "Whirlwind" are popular pumping equipment and are widely known to the domestic consumer. The first batch of pumps were released by the company more than 40 years ago. At that time, the production facilities of the enterprise were located in the Novosibirsk region.

Today, production is fully located in China, which allows you to significantly reduce the cost of products and make it the most popular in its segment.

Drainage pumps are widely used in the household, construction and everyday life. With their help, the water is pumped out from the flooded basements, bowls of pools and wells.The most powerful models are designed for the extraction of very dirty liquid with inclusions of large fractions and impurities. Pumps are irreplaceable when cleaning waste holes and construction ditches, cellars, sewer capacities and country toilets. A characteristic feature of the device is the ability of the pump to carry out a rapid pumping of fluid without increasing the pressure. Thus, “Whirlwind” is designed not only for water intake, but can be used when watering, and to ensure uninterrupted water supply for cottages and cottages.

Pump "Whirlwind" is a centrifugal structure consisting of a housing, an engine and a pump. The housing includes a motorized and float-equipped working chamber. The motor starts immediately after the chambers are filled with water, while the impeller is driven by the rotor, and under the influence of centrifugal force pushes the liquid to the diffuser walls. As a result, a discharged area is formed in the area of ​​the inlet valves, which ensures the automatic suction of new portions of fluid. On the diffuser outlet, on the contrary, an increased pressure is formed, which ensures the movement of water.

Excellent pumping capacity, providing a free flow of fluid containing various suspensions, due to the absence of thin tubes, channels and small elements in the design of the pump.

The device is installed at the bottom of the tank, which is why this type of pump is called submersible. Workflow management is carried out thanks to the float mechanismlocated in the working chamber: when the water level reaches the optimum level for operation, the float automatically turns on the motor and, conversely, turns it off when the level drops below the critical point. The device is equipped with a reliable electrical insulation system that prevents water from entering the engine and to the elements of electrical wiring.

A large number of positive reviews and high consumer demand for pumps "Whirlwind" are due to a number of indisputable advantages of these units:

• Compact size and low weight make the device mobile and convenient to use.
• The ideal ratio of price and quality makes it possible to purchase a high-quality and reliable device for little money.This product "Whirlwind" favorably with the pumping equipment of well-known foreign brands, in no way inferior to them in efficiency and durability.
• The robust case tolerates shock and mechanical loads, has high anti-corrosion properties and is characterized by complete tightness. It is allowed to immerse the pump to a depth of 8 to 10 meters.
• A wide range of products allows you to choose a device for any household and technical needs.

• High performance and resistance to extreme temperatures significantly expand the range of application of pumps. The capacity of the apparatus varies from 5 to 15 cubic meters of water per hour and depends on the purpose and power of the device.
• Thanks to the equipment of the pump with the float system, the device is reliably protected from idling the engine. In the case of lowering the water level below a certain mark, the float will turn off the motor, preventing breakage and overheating.

The disadvantages include the mandatory presence of electrical wiring and extension wire when the pump is connected and the impossibility of pumping liquid with large-fractional inclusions,whose size exceeds 35 mm.

Drainage pumps "Whirlwind" are submersible models and are labeled "DN".

According to the degree of contamination of the pumped liquid, they are divided into three groups:

• devices for the supply of clean drinking water;
• devices for liquids with moderate pollution, capable of pumping water with inclusions from 5 to 12 mm;
• pumps for water with a high degree of pollution, designed for pumping out liquids with large fractional suspensions ranging in size from 12 to 35 mm.

Apparatus is classified and by appointment. There are professional and non-professional models. The first ones are distinguished by high productivity and are used for drawing water from construction pits and pools, as well as for professional cleaning of cesspools and septic tanks.

Drainage pumps "Whirlwind" designed just for domestic needs and can pump from 5 to 16 cubic meters of water per hour, while specialized models are able to cope with a volume of from 100 to 700 cubes. According to the mode of operation, there are pumps with continuous operation and units with the possibility of interrupting the workflow.

The model range of the company is represented by a large number of pumps, differing in their purpose, power and cost.

Consider some of them:

• DN 300. This pump is the most low-power of the entire series of products "Whirlwind" and is designed for temporary use in the suburban period. With it, it is possible to pump water from a flooded basement, supply water for irrigation from a natural pond and pump the fluid between two tanks.

Before you begin to purchase a drainage pump, you should decide on the operating conditions of the unit, on the basis of which and select the required power. For seasonal use in country and garden plots, for watering the garden and the vegetable garden, as well as for pumping water into the summer shower and bath tanks, you can opt for low-power household units DN 300. The performance and throughput of these models are designed specifically for this type of operation. With careful use and proper storage, units can last for many years without the need for replacement or repair.

For individual housing and sanitary needs, you should purchase more powerful and productive models DN 900 and DN 1000N, able to pump out very polluted water with abundant inclusions of suspended solids. The bodies of these units are made of stainless steel, which makes the pumps shockproof and resistant to corrosion and any kind of mechanical effects.

Strict compliance with the instructions for use of the device will ensure uninterrupted operation of the pumps and significantly prolong their service life.

It is forbidden to pump and pump water with stones, large tangled fibers, metal elements and solid objects whose size exceeds the maximum permissible norms for each model.

It is not recommended to pump out and pump over liquids containing chemically active substances.. Interaction with aggressive components can adversely affect the design elements of the pump and disable them.

Vortex drainage pumps help solve the problem of draining flooded basements, provide uninterrupted water supply to country houses and help to quickly transfer water from one reservoir to another. The wide model range significantly expands the scope of their application, and the low price distinguishes the products of this company from the pump equipment of other manufacturers.
