Suction water pump: specifications and reviews (photo)

To ensure effective water supply of private houses and country cottages it is necessary to use self-priming water pumps . This equipment is located a short distance from the water intake, lifting the liquid from the depths, passing through itself. The models presented on the market are characterized by a multitude of technical characteristics that should be studied by the consumer in the process of choosing such a device for domestic use. A suction pump for water often goes along with a membrane or storage tank in autonomous systems of suburban water supply. However, such equipment can certainly be called a pumping station.

Types of suction pumps

If you decide to choose a suction pump for water, you can prefer a model that has a remote or built-in injector. In the first case, the initial suction and subsequent lifting of the liquid is carried out by vacuum. In the process of operation, the injector plants create a lot of noise, so for their placement in the territory should be selected special rooms, which are located some distance from the house. The main advantage of suction pumps, which are equipped with injectors, is their ability to lift liquid from a very impressive depth, which on average is 10 meters. In the source of water intake, it will be necessary to lower the supply pipe, while the equipment itself is installed at a certain distance from it. Such an arrangement makes it easy to monitor the operation of the equipment, which has a positive effect on the service life.

Council of the master

If you decide to choose a suction pump for water of the above-described design, you need to provide protection against dry running, which can provoke equipment failure, which is what happens in most cases.

Characteristics of suction pumps without an injector

The second type of equipment is pumps that produce water without the use of injectors. These models provide fluid suction by means of a hydraulic device that has a multi-stage design. Hydraulic devices work absolutely silently, especially if you compare with the injector models. However, they are able to take liquid from a shallower depth.

Principle of operation and device

The suction pump for water can be centrifugal. In this case, a wheel is located in the body that has a spiral shape. The latter is quite rigidly fixed and consists of two disks, which are provided with blades. They are bent in the opposite direction from the direction of rotation of the wheel. By means of nozzles of a certain diameter, the pump is connected to a suction and discharge pipeline. Similar suction pumps for water operate on a specific principle, which consists in rotating the impeller, which occurs after the suction pipe and the housing are filled with water. The centrifugal force that arises at the moment of rotation of the wheel, displaces the liquid from the central part, discards it on the surface of the peripheral areas. This creates an increased pressure, so water is forced out from the periphery and enters the pressure pipeline. During this period, in the central part of the impeller, the pressure, on the contrary, decreases, which leads to the fact that the liquid enters the pump body, crossing the suction pipe. This algorithm is used for the continuous supply of water by a centrifugal pump.

What else is important to know about the centrifugal suction pump

The suction pumps described above for water can have in the construction not one but several impellers. Accordingly, their number can be distinguished single-stage and multistage installations. The number of wheels does not affect the principle of operation of this equipment. The fluid moves under the influence of the centrifugal force, which is formed during the operation of the rotating wheels.

Vortex suction pump characteristics

If you want to choose a suction pump for water, Wilo can be an excellent solution. Air is sucked into the body due to the vacuum force that results from the rotation of the impeller, as the latter is the impeller. At the next stage, the air masses are mixed, which gets inside the pump. Mixing is carried out with the working fluid, which is contained in the body of the device. After the liquid and the air mixture have entered the working chamber, these components are separated from each other, this principle is based on the difference in densities. The separated air is discharged through the supply line, while the liquid begins to recirculate inside the working chamber. After the air is removed from the suction line, the pump is filled with liquid and begins to operate on the principle of a centrifugal installation. On the suction flange there is a check valve, designed to exclude the possibility of air entering the pipeline. Among other things, it is necessary to ensure the presence of liquid in the pump chamber. Thanks to this principle of operation and the arrangement of a vortex suction pump, water is lifted from the depth filled with the chamber. At the same time, water can be pumped from 8 meters without a bottom valve.

What is important for a consumer to know about vortex pumps

A vortex suction pump for water, the characteristics of which were presented above, can be used to pump not only water, but also mixtures of air and liquid.

Customer feedback on centrifugal and vortex pumps

If you decide to install a suction pump for water in the apartment, it is important to initially choose which version it is preferable to. According to the buyers, the centrifugal unit is larger in size than the vortex suction pump. The latter is chosen by buyers for the reason that it is characterized by very compact dimensions. However, owners of country houses and apartments have to the liking of the fact that centrifugal pumps produce little noise, because it is very important when used in everyday life. Visiting the store, you can see that the vortex models have a less impressive cost, which, as consumers emphasize, is sometimes a very important factor. The water head, which can be created with the help of vortex equipment, almost seven times exceeds the similar capabilities of suction centrifugal models. If you decide to choose a suction pump for water, a photo of this equipment should be considered well in advance. Experts advise not to be guided exclusively by cost, since excessively cheap products sometimes are not capable of ensuring the normal functioning of water supply systems. It is desirable to start from the purpose of the device and technical characteristics. If you competently approach the choice of the model, follow the manufacturer's recommendations when operating, then you can count on a very long operation of the purchased equipment.

Characteristics of the "Agidel-M" pump

If you decide to choose a suction pump for dirty water, you can prefer this model, which is very small in size. Weight reaches six kilograms, and power consumption is 370 watts. The temperature of the water pumped by the pump should not exceed 40 degrees, the device can suck up water from a depth of up to seven meters, while the model can operate for a very long time without stopping, because the manufacturer provided the device with a special protection that eliminates the possibility of overheating. If this model will be additionally equipped with an injector, it can be used in wells, the depth of which reaches 15 meters. Pumping through the device can be water not only from wells and wells, but also pools, as well as artificial reservoirs. In the process of taking water from a reservoir or pool, it must be ensured that a distance of 0.35 meters is maintained from the bottom to the intake valve. The maximum head that the pump can create is 20 meters of water.

Characteristics of the "Agidel-10" pump

If you decide to purchase a suction pump for dirty water, you can prefer the above model, which is more powerful than the "Agidel-M". This unit consumes more than 500 watts during operation. At the same time, the equipment provides quite impressive head, which is 30 meters. The model weighs nine kilograms and does not require water filling at start-up. It is recommended to use such a device when conducting a water pipe to a residential building, because due to its impressive capacity, the equipment supplies water with a sufficiently good head immediately to several points simultaneously, for example, to the kitchen and bathroom.

Conclusion

The suction pump for water (12 volts) should be installed on a flat solid surface, as this will determine the quality of the work. To ensure protection from direct sunlight and precipitation, a special container should be built or equipment installed inside the utility room. The first method is more preferable, because due to hoses and long pipes one can face the problem of lowering the head of water.
