It is quite difficult to imagine modern housing without water supply, and it does not matter at all whether the building is located outside the city or within its boundaries. Many owners of suburban real estate and summer cottages are increasingly choosing an autonomous system that can provide a house with water. Immediately after completion of well drilling, the question arises as to which pump is best for the well to choose.
Key selection criteria
The pump acts as the heart of the system. The supply of water at home will depend on how correctly it is possible to choose this equipment. When visiting a store, you should be guided by several criteria that will make the right choice. And if you can’t decide now which pump is best for a 20 meter well, then after reading this article you will be able to determine for yourself. Among other factors, attention must be paid to the total depth of the well and the level of groundwater. These characteristics are most often key when buying a device. The pump data sheet should contain information about the depth for which the unit is intended. If this value is unknown, then you can independently measure. For this, a dry rope is used, at the end of which a load must be fixed.
After the rope is placed at the bottom of the well, it will be necessary to measure the remaining dry part, which will determine the distance to the water. As for the wet part, it will allow you to calculate the height of the water column. If you are thinking about which pump is best for the well, then it is important to consider the need for water. The selection of such equipment will be impossible without determining the value, which will vary from twenty to two hundred liters per minute. If we take into account the fact that one person spends about 200 liters of water during the day, then a family of four will have to purchase a pump, the power of which varies from thirty to fifty liters per minute. You can choose a device that involves a certain power reserve, but you should take into account the moment that this factor can seriously affect the cost.
If in addition to house maintenance there is a need for watering the site, then you need to calculate the power, taking into account weather conditions and the size of the territory. For irrigation, as a rule, there is a need to use 200 liters of water per day. This indicates that it is necessary to choose a pump taking into account the power, which will be 50 liters per minute more than the above.
Flow rate selection
If you are faced with the question of which pump is best for the well, it is important to consider the flow rate of the well. It is almost impossible to measure the value as accurately as possible. This parameter is estimated only approximately. It is important to carry out some actions that involve determining the time for pumping a well. After that, you need to fill the well with water, and then divide the second number into the first. The result will be the flow rate of the well. However, this option will not be enough to select equipment.
Pressure pump selection
If you are considering the question of which pump is best for the well, it is important to pay special attention to the pressure. To calculate this value, add 30 to the depth of the well, expressed in meters. This will allow you to get the height of the water column. As a rule, the resulting value increases by 10%. This will select the device correctly. Thus, if the well depth is 45 meters, then the calculated column height will be 75 meters. If you increase this figure by 10%, you will be able to get a figure equivalent to 83 meters. Thus, the most suitable option would be a model with a pressure of 90 meters.
Determination of the model of the pump by the diameter of the well
If you are considering pumps for wells, which is better, you need to determine in advance. The diameter of the well is the value that is necessary to determine the power of the equipment. This parameter is taken from the passport of the well if drilling was carried out by a specialized company. If such documentation is not available, the owner of the site can make measurements on his own. It is important to consider that one inch is equivalent to an indicator of 2.54 centimeters. The largest number of devices on the market today is for wells with a diameter of 4 inches. In some cases, there is a need to order a device model from a catalog. If you have the opportunity to choose the diameter of the well, then it is best to be exactly 4 inches.
Characteristics of the pump of the brand Aquario ASP 1,5-40-75
If you are faced with the task of which centrifugal pump is best for the well to choose, then you can pay attention to ASP 1.5-40-75. It is used to pump clean water from wells and wells. It can be used in private water supply systems for domestic use, irrigation and irrigation. The nominal pressure of this equipment is 40 meters, and the flow rate is 1.5 m 3 / h. The case is made of stainless steel and the diameter of the pump part is 75 mm (3 "). Brass is used for the equipment head. An oil-filled single-phase motor is installed inside. It is important to note that such equipment cannot be used at a water temperature that exceeds +35 degrees. an hour the maximum number of starts is 20. Water should not contain sand and excessive impurities, but the maximum permissible value of foreign matter is 1120 g / m 3 .
Description of the pump brand Aquario ASP3B-100
You can independently purchase pumps for wells. Submersible (which one is better , you should choose before visiting the store) is represented by manufacturers in a wide assortment. Among others, the ASP3B-100 model can be distinguished. The nominal pressure of this equipment is 100 meters, the flow rate is equivalent to a limit of 3.0 m 3 / h. The diameter of the pump part is 100 mm (4 "). The impellers and diffusers are made of high-strength technopolymer, and the body of the device is made of stainless steel.
Description of borehole pumps of the Grundfos brand
If you choose which pump is best for a well, then you may prefer equipment of the aforementioned brand. These submersible devices are manufactured in a monoblock design, and are also equipped with the necessary accessories for connecting the unit. The case diameter is 3 inches, which is 76 millimeters. The equipment can work in wells, the diameter of which is equivalent to this indicator, characteristic of the equipment body. If we consider the design in more detail, the device is multistage, centrifugal. Impellers are located on the drive shaft, each of which increases pressure, and its maximum value can be 200 meters. If you cannot decide which vibration pump is best for the well, then you need to first decide what tasks will be assigned to it. Thus, if there is a need to supply water to private farms or a small enterprise, Grundfos brand equipment can be chosen by you, since it is specially designed to solve such problems.
Description of ESPA brand pumps
If you are faced with the question of which pump is better to choose for a well, then you can purchase ESPA equipment that has managed to establish itself in the market for relevant products. If there is a need to pump water with sand content, the volume of which reaches an indicator of 185 g / m 3 , then this equipment is the best suited. The hydraulic part is made in such a way that it has the properties of resistance to clogging and abrasion. The impellers have a floating free wheel, which allows to reduce the wear of the impellers with an impressive sand content in the liquid. These design features allow you to prevent blocking of the working elements, providing soft functioning and long service life of the device.
If you are considering borehole pumps in the store, which is better, it is important to decide before you purchase. Choosing the equipment of the manufacturer ESPA, you get a device that has the function of internal engine cooling, which ensures reliable operation of the unit in continuous operation. In this case, the equipment can be immersed in water, either completely or partially. If there is a need to purchase a device with internal engine cooling, it is best to prefer this manufacturer, as it produces pumps whose diameter is 4 inches, which in this case is very rare.
Conclusion
If you can’t decide which pump is best for the well, you can consider each of the manufacturers presented. Speaking of the above, they have proven themselves in the pumping equipment market.
