Owners of summer cottages and country houses often think about the individual water supply of their possessions. Basically, water is extracted from wells or wells. You can do this manually or by using a pump. The correct choice of the pump often depends on the quality of water and its quantity. So that you do not come across a number of problems in the future, take this seriously seriously. So, how to choose a pump for a well?
Pump Selection Criteria
Pay attention to such factors when choosing a pump:
- Depth of well and water level . This factor is the main one. If you pick the wrong pump, then you get either the wrong amount of water, or the pump is quickly worn out because of the heavy load. You can refer to specialists who are boring the well, so they immediately measured this value. If you did not do this, then a stone and a cable will come to your aid. Tie a rope around the stone and lower it into the hole. On the dry side, you determine the distance to the water. On wet - the required height of the pump column. These measurements will help you choose the most appropriate pump size for your well, which will be listed in the product passport.
- The volume of water . Precisely count the amount is impossible, because in winter you will not water the site, as in the rain. Take into account the number of family members, the individual water flow per person, and the size of your site. Calculate the approximate amount of liters and add to them another 20-30 for the stock. The optimal option for most - a pump that pumps 50 - 70 liters per minute.
- Debit wells . This indicator can vary with the time of year. In spring, water fills the well faster than in winter. You can measure the approximate value yourself. Mark the time for which the well is completely filled and how quickly it is emptied. Divide the filling time for the time of devastation and get the data you need.
- The degree of water pollution . This is a very important criterion, because there are pumps that are very sensitive to sand, clay and other foreign objects that are hidden at the bottom of the well.
Selecting a pump for a well
Surface pumps for wells are installed without immersion, that is, over the ground. But the main barrier is that they are not designed for pumping water from wells, more than eight meters deep.
Submersible pumps for wells are designed for large depths. They will last you much longer than surface pumps.
Consider the types of submersible pumps for wells:
- Screw pump for wells. Drains the water from the depths, but misses a small level of various impurities. It is relatively inexpensive, also reliable. If you need water only for watering the plot, you can buy just such a pump.
- Centrifugal vortex pump for wells. Is the most optimal option. The water that he pumps, is clean enough and suitable for eating. Its internal mechanism due to the shafts and blades creates a centrifugal force, the water rises fast enough. The more powerful the pump, the more expensive it is.
- Vacuum pumps for wells. Such pumps are not designed for pumping water, they are installed in addition to purify water from gas and other chemicals.
- Vibration pumps. This is a more inexpensive option, but has a number of drawbacks. The motor of such a pump
It must be protected from sand and other impurities. If you do not, then soon it will fail and repair of such a device will cost you dearly. In addition, the pump generates radio waves during operation. The more power, the stronger the wave. These vibrations destroy the walls of the well.
After determining which submersible pump is best for the wells, pay attention to the price of the device itself. Do not be stingy, because the quality of the pump depends on the quality of water in your area. Look carefully at every detail and how it is fastened. If you notice rust on the details, then do not take such a device. Carefully read the specifications in the technical passport, if they are as close to your requirements, then buy it safely.
