To work with contaminated water (pumping out flooded rooms, watering from nearby natural water bodies, draining ravines), it is better to use a drainage pump. Its design allows the processing of media mixed with fairly large particles of garbage. And this does not affect the performance of the unit. Well proven drainage pumps Whirlwind. Domestic products are in great demand among craftsmen.
Device, principle of operation of drainage pumps Whirlwind
All units Whirlwind drainage type only centrifugal. Devices are surface or submersible. Regardless of the type of device, its main working nodes are repeated:
- working and pump chambers, which are enclosed in one housing;
- a stator motor with two winding layers;
- float fuse (for submersible models);
- end seal;
- impeller with blades;
- a suction port with a strainer (the cell size determines the size of the transmitted particles).
The difference between surface and submersible drainage pumps lies in the principle of their installation. The first are mounted near a pond. The second is immersed directly in the aquatic environment.
The principle of operation of the pumps:
- When the engine is turned on, an electric current sets in motion a rotor with working blades.
- A rotating wheel forms a pressure drop in the chamber. Due to this, water is sucked through the inlet pipe.
- The blades activate the centrifugal force, press the liquid against the walls of the chamber and thereby push it up.
- The pressure in the chamber drops again and a new intake of water occurs. In this case, the pump does not turn off.
The cyclic differential pressure in the system provides a stable pressure and a smooth flow of water.
Advantages and disadvantages
Among the main advantages of vortex drainage pumps, users distinguish the following:
- device reliability;
- long term of operation;
- good performance;
- tightness of the case;
- resistance of work units to corrosion;
- compactness;
- light weight and mobility;
- the presence of a transport ergonomic handle.
The only drawback of the master is the small length of the electric cable and the need to tap it.

How to choose a pump
To select the optimal model of the drainage pump should be guided by such criteria:
- The operating conditions of the device. It is necessary to take into account the permissible size of contaminants in the pumped water.
- The pressure of the device according to the instructions. It is important to know the depth with which the liquid will rise and the horizontal length of the hose to the point of water discharge. It is important to note that every 10 m of the horizontal section of the network is equal to 1 meter of pressure.
- Power unit. For some masters, this criterion is decisive after the main characteristics.
- Performance. It is especially important when pumping dirty water from flooded rooms. If the water will arrive faster, the pump simply can not cope with its functions.
In addition, the masters pay attention to the cost of equipment and the availability of protective options.
Installation Principles
Installation of a submersible drainage pump does not cause difficulties for the master. Work is performed in the following sequence:
- An outlet hose is attached to the outlet pipe with a fitting. It is important that the connection is tight.
- Check the electric cable for integrity, absence of damage.
- The pump is lowered into a pond or flooded room so that it abuts against the bottom. When installing the device in a pond / stream, a solid solid foundation must be placed under it so that the incoming pipe does not pull sand from the bottom.
- It remains to connect the unit to the network.
If the device uninterruptedly pumps out / delivers dirty liquid, then the pump is installed correctly.
Operational Features
Whirlwind submersible drainage pumps do not require complicated maintenance. But the manufacturer recommends the following:
- It is forbidden to distill any chemicals and oils through the working chamber of the pump.
- Particles of metal and fibers should be avoided in pumped water.
- The unit is lowered into the processed environment only not connected to the network. Electricity is supplied after the dive.
- Store the pump preferably in a warm room, and well-dried previously.
Subject to the above recommendations, the unit serves without breakdowns.
Prices for drainage units in Moscow are quite acceptable. Depending on the model, the cost of the device is from 2,200 to 5,500 rubles.
Owner reviews
Judging by the reviews of the Whirlwind drain pump, the units fully justify their cost and the declared technical characteristics.
Roman, 29 years old. At the dacha in the spring often heats the basement. And in the summer rainy season the same trouble. I had to look for an urgently inexpensive drainage pump. Really helps Whirlwind DN-300. I've been using it for two years now. No complaints. He threw it into the water, pumped it out, removed it.I do not lubricate, do not dry additionally. Fully justifies its price.
Ilya, 32 years old. The pump DN-750 Whirlwind was originally taken for irrigation. Pulling water from a nearby pond. The distance from the garden to the reservoir is 30 meters. When immersed 3 meters in the water, the pump pumps normally. In about 1.5-2 hours, completely pour in the heat of 4 hundred plantings. I put a 5 cm thick board flooring under the unit so that the sand does not suck. The second summer will be like a pump to use. Recommend.
Nick, 35 years old. For me, the DN-1100 model was a godsend when I bought a house at the very bottom of the village with a high groundwater location. So as not to build a complex drainage system, I use this pump. When the ravine is completely filled, I throw the unit into it and pump out the water to the end. I dump it in a pond nearby. He laid a special brick platform under the pump. The float always shuts off the pump itself when the water is completely pumped out.
Yura, 42 years old. Recently, the drainage well of the septic tank had to be completely pumped out, since its bottom apparently silted up and the water stopped leaving. The neighbor asked the pump Whirlwind DN-500. I pumped out the whole literally in an hour. I am satisfied. I understand that you yourself need to take this. You never know what else with the well.
