To ensure efficient water supply to private houses and country cottages, it is necessary to use self-priming water pumps. This equipment is located at a short distance from the water intake, raising liquid from the very depths, passing through itself. The models on the market differ in many technical characteristics that the consumer should study in the process of choosing such a device for domestic use. A water suction pump quite often comes with a membrane or storage tank in autonomous suburban water supply systems. However, such equipment can be safely called a pumping station.
Varieties of suction pumps
If you decide to choose a suction pump for water, then you can prefer a model that has a remote or built-in injector. In the first case, the initial absorption andthe subsequent rise of the liquid is carried out due to rarefaction. In the process of operation, ejector installations create a lot of noise, therefore, for their placement on the territory, special rooms should be selected, which are located at some distance from the residential building. The main advantage of suction pumps, which are equipped with injectors, is their ability to lift liquid from a very impressive depth, which averages 10 meters. In this case, it will be necessary to lower the supply pipe into the source of water intake, while the equipment itself is installed at a certain distance from it. This arrangement makes it easy to monitor the operation of the equipment, which has a positive effect on the duration of the service life.
Master's Tip
If you decide to choose a water suction pump of the above design, you need to provide protection against dry running, which can cause equipment failure, which happens in most cases.
Suction pump specifications without ejector
The second type of equipment is pumps that lift water without the use of injectors. These models provide liquid suction with a hydraulic device that has a multi-stage design. Hydraulic devices operate completely silently, especially when compared with injector models. However, they are able to takeliquid from shallower depths.
The principle of operation and device
The water suction pump can be centrifugal. In this case, the wheel is located in the housing, which has a spiral shape. The latter is rather rigidly fixed and consists of two discs, which are equipped with blades. They are bent in the opposite direction from the direction of rotation of the wheel. Through pipes of a certain diameter, the pump is connected to the suction and pressure pipelines. Such water suction pumps work according to a certain principle, which is the rotation of the impeller, which occurs after the suction pipe and casing are filled with water. The centrifugal force that occurs at the moment of rotation of the wheel displaces the liquid from the central part, throws it to the surface of the peripheral sections. This creates an increased pressure, so the water is displaced 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 casing, crossing the suction pipeline. This algorithm is used when water is continuously supplied by a centrifugal pump.
What else is important to know about the centrifugal suction pump
The water suction pumps described above may have not one, but several impellers in their design. According to their number, one-stage andmulti-stage installations. The number of wheels does not affect the principle of operation of this equipment. The fluid moves under the action of centrifugal force, which is formed during the operation of the rotating wheels.
Characteristics of the vortex suction pump
If you want to choose a water suction pump, Wilo can be the perfect solution. Air is sucked into the housing due to the vacuum force that occurs as a result of the rotation of the impeller, the latter being the impeller. At the next stage, the air masses are mixed, which enters the pump. Mixing is carried out with the working fluid contained in the body of the device. After the liquid and air mixture have entered the working chamber, these components are separated from each other, this principle is based on the density difference. The separated air is removed through the supply line, while the liquid begins to recirculate inside the working chamber. After air is removed from the suction line, the pump is filled with liquid and begins to work according to the principle of a centrifugal installation. There is a non-return valve on the suction flange, 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 a similar principle of operation and the device of a vortex suction pump, water is lifted from a depth with a filled chamber. In this case, water can be pumped from 8meters without a bottom valve.
What is important for the consumer to know about peripheral pumps
The vortex suction pump for water, the characteristics of which were presented above, can be used to pump not only water, but also a mixture of air and liquid.
Consumer reviews of centrifugal and peripheral pumps
If you decide to install a suction pump for water in the apartment, it is important to initially choose which type to prefer. According to buyers, the centrifugal unit is more massive in size than the vortex suction pump. The latter is chosen by buyers for the reason that it has a very compact size. However, the owners of country houses and apartments like the fact that centrifugal pumps make little noise, because this is very important when used in everyday life. By 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 pressure that can be created using vortex equipment is almost seven times higher than the similar capabilities of suction centrifugal models. If you decide to choose a suction pump for water, it is recommended to consider a photo of this equipment in advance. Experts advise not to be guided solely by cost, since overly cheap products are sometimes not able to ensure the normal functioning of water supply systems. It is advisable to build on the purpose of the device andspecifications. If you correctly approach the choice of model, follow the manufacturer's recommendations during operation, then you can count on a very long functioning of the purchased equipment.
Characteristics of the pump "Agidel-M"
If you decide to choose a suction pump for dirty water, then you can prefer this model, which differs in very small dimensions. Weight reaches six kilograms, and power consumption is 370 watts. The temperature of the water pumped through the pump should not exceed 40 degrees, the device is capable of sucking water from a depth of up to seven meters, while the model can function for a very long time without stopping, because the manufacturer has provided the device with special protection that eliminates the possibility of overheating. If this model is additionally equipped with an injector, it will be possible to use it in wells, the depth of which reaches 15 meters. Using the device, you can pump water not only from wells and wells, but also from pools, as well as artificial reservoirs. In the process of taking water from a reservoir or pool, it is necessary to ensure that a distance of 0.35 meters is maintained from the bottom to the inlet valve. The maximum pressure that the pump can create is 20 meters of water column.
Characteristics of the pump "Agidel-10"
If you decide to purchase a suction pump for dirty water, you can give preference to the above model, which is more powerful than Agidel-M. This unit consumes more than 500 watts during operation. At the same time, the equipment provides a fairly impressive pressure, which is 30 meters. The model weighs nine kilograms and does not require filling with water at startup. It is recommended to use such a device when conducting water supply to a residential building, since due to its impressive power, the equipment supplies water with a fairly good pressure to several points at once at once, for example, to the kitchen and bathroom.
Conclusion
The water suction pump (12 volts) must be installed on a flat hard surface, as the quality of work will depend on this. To provide protection from direct sunlight and precipitation, a special container should be built or equipment should be installed inside the utility room. The first method is more preferable, because due to hoses and long pipes, you may encounter the problem of lowering the water pressure.
