How to choose a household water pump? Expert advice and manufacturer feedback

Water is a vital resource for humans. However, in some cases, it can deliver a lot of hassle.

Need to use a pump

During snowmelt or rain, an excessive amount of water can cause certain harm to all kinds of buildings, washing away the grounds, and also flooding the basement rooms. An irreplaceable assistant in this case becomes a household water pump. With its help, you can get rid of excess moisture, even if it has a certain degree of contamination. That is why such equipment can be considered indispensable in a suburban farm. By means of such a device, it is possible to pump water from reservoirs according to the type of foundation pits and basins. That's why, when buying a pump, you need to think about what functions to pay attention to the use of the unit was the most effective.

Selecting a pump by material

Before you buy a household water pump, you need to think about what material should be in the base of the enclosure. Characteristics can not be called insufficiently important. Depends on it the cost of equipment, reliability and lifetime. According to the material of manufacture, the described devices can be made entirely of plastic. It should be remembered that such models are least durable, but are cheaper in comparison with similar solutions from other materials. From the conveyor and go plastic pumps, the working mechanism of which is made of stainless steel. This indicates that the internal elements of the unit are not subjected to aggressive external environment and corrosion. The third variant assumes a body made of stainless steel or cast iron. Such equipment tops the rating of pumps by the length of service life, due to the stability of the parts to any damage. The domestic water pump can be lobed, while the same components can be made from stainless steel, which is the cheapest option, or from a technopolymer that has greater resistance to wear and corrosion. However, the price of such solutions is much higher.

Classification by installation method

The domestic water pump can assume different installation methods. Among others, one can distinguish a surface variety that pumped out liquid even from a very impressive depth. Such devices are used, as a rule, in the conditions of pumping stations for connection to the well. The device can also be submersible. The housing must be partially in the evacuated liquid. Such models are used for pumping water from small ponds and cellars. With regard to submersible options, they must be completely in the evacuated medium. Use them is most appropriate for draining basements or pools.

The experts' opinion on the length of service life

If you are interested in domestic pumps for pumping water, then it is worth to listen to the opinion of specialists. Professionals claim that during the operation of the equipment, the motor may overheat, which can lead to breakdowns. Negative on the life of the mechanism affects the work at a low level of the pumped liquid. If you do not want to face overheating of the engine during the first hours of using the equipment, then it is necessary to take advantage of the experience of specialists who claim that the pump must have a thermal relay. It switches off the unit when the temperature reaches the maximum permissible level. If the pump has a built-in float, the equipment switches off automatically when the liquid level decreases during the pumping process. This helps to exclude flooding at a time when the owners are absent during the flood. If you choose domestic pumps for pumping water, then you should pay attention to the units that are equipped with aquasensor technology. Due to the presence of the regulator, it is possible to set the liquid level limit for switching off and on the equipment. A minimum mark can be set even by 5 millimeters. Such pumps are used in narrow reservoir conditions where the float switch can not function.

Expert opinion on performance

If you choose domestic submersible pumps for water, then you need to take into account the necessary performance. To do this, the scale of the proposed actions is determined. You need to know how much water will need to be pumped out over a given period of time. Household pumps for a minute help to cope with 180 liters. If you are facing the task of pumping excess fluid from the pool or basement, then this equipment is quite suitable. But you should know that the higher the upper reset point, the more impressive will be the performance losses.

Expert opinion on the head of the device

Considering household submersible pumps for water, you need to know the distance and height from which water is supplied. This data is needed to calculate the head when performing a specific task. The height can be calculated by determining the step between the level of the pump location and the outlet point of the liquid from the nozzle. In this case, it should be noted that there will be a loss of 1 meter of pressure for 10 meters of the pipeline or hose.

How to choose the equipment depending on the pumped out environment

If you are considering household water centrifugal pumps for water in a store of appropriate products, you should be aware that each equipment has a specification that is indicated by the fractionality of the impurities contained in the liquid. It is precisely a certain size of foreign particles that the unit will be able to pass through the mechanism without reducing the operability at the same time. According to experts, if the devices are divided according to these characteristics, the permissible size of foreign impurities will be as follows. Self-priming pumps for domestic water should be chosen for swimming pools and rain tanks in the event that the mechanism is capable of passing particles through itself up to 5 millimeters. In this case, the equipment is considered suitable for slightly contaminated and clean liquids. If the mechanism is capable of passing particles from 5 to 25 millimeters, it is intended for medium-contaminated fluids with impurities. It is advisable to use it for wells or excavations. If you choose domestic pumps for dirty water, then you should prefer those that are able to skip elements from 25 to 38 millimeters. In this case, the equipment can be used for melt and rainwater. If we are talking about household pumps, then they should be used in environments that do not exceed 40 degrees. This is why it is impossible to use such equipment to pump hot liquids. For such tasks it is necessary to prefer industrial units that are able to cope with this.

Selecting a pump to increase pressure

When choosing such equipment, it is necessary to take into account the tasks to be performed. Sometimes there is a need to strengthen the weak pressure, whereas in other cases there is a need for lifting liquid from the first floors to the last. In the first case, you can do with a small in power and size device. Such structures are installed in the pipeline. In the second case, it is necessary to prefer a high-pressure centrifugal pump, which is equipped with a hydraulic accumulator. Household water pumps that increase the pressure, which were described in the second case, assume operation in one of two modes. Among them you can select automatic and manual. In the store you can choose equipment that provides a different method of cooling the case. This task can be realized by means of an impeller of the engine or by means of pumped water. If the cooling is performed with the help of blades on the shaft, the design assumes the presence of a dry rotor. Such engines are characterized by high efficiency and low noise level during operation. Domestic water pumps that increase the pressure can be cooled by means of a pumped liquid. They have a wet rotor, the equipment at the same time works almost silently.

Reviews of manufacturers

If you choose domestic water pumps, the price of this equipment should certainly interest you. It is important to pay attention to the manufacturer. This is an essential criterion. Citizens of Russia primarily pay attention, of course, to the domestic producer. Among others, the "Water meter" model can be singled out. According to consumers, with its help it is possible to pump water from a well or a well. The liquid may contain a certain amount of sand. The lowest cost of such equipment is 6200 rubles. Choosing domestic water pumps, the price of which is presented in the article above, seems high, you can pay attention to less expensive models. Among them, it is impossible not to mention the unit "Kid", which is the fruit of Russian production. It is advisable to use such a pump to supply liquid from the wells. It should be noted that the equipment does not have a high performance, but it is quite cheap. For this design, you will have to pay 2500 rubles. If you are facing the task of supplying a suburban house, you can choose the brand "Brook". This pump can work in shallow water bodies, wells and wells. He is unpretentious to the quality of the pumped liquid, and the average cost of it is even lower - it is 2000 rubles.

Alternative solutions

If you want to purchase a domestic waste water pump, you can pay attention to the brand "Gileks". This manufacturer represents a wide range of equipment for both sewerage and water supply. These units are of high quality, long service life and average cost. If necessary, you can choose a pump for a well or a well, regardless of whether the water of what quality is to be pumped out. The minimum price for such equipment is 3000 rubles.

Reviews of manufacturer Grundfos

Household high pressure pumps for water are manufactured by Grundfos. This company is located in Germany and produces equipment that can work in wells and wells. Each unit is equipped with sensors for dry running, overload, overheating, and voltage variations in the network. This indicates an extended service life. However, one should also count on a higher cost, which is kept within 10,000 rubles. According to consumers, these models are leaders in their field.

The experts' opinion about the dimensions of the equipment

If you are considering domestic high-pressure water pumps, then you need to take into account the parameters. The determining value, according to experts, is the diameter of the pump, which, for the correct operation of the unit, should be 10 millimeters shorter than the diameter of the well. This value is minimal. Thus, equipment, whose diameter is equivalent to 100 millimeters, can be used for a well with corresponding parameters equal to 110 millimeters. When buying, you will see that the diameter of the pump is most often indicated in inches. When determining the final dimensions, one should follow the standard: 1 inch is equal to 2.54 cm.
