How to choose a pump for the well - the main parts that

It is no secret that the reliability of the entire system depends on the performance and durability of the pumping unit. At the same time there is no single option for all sources, you have to decide on the situation, what pump to choose - for a well of 20 meters and a well of 10 meters the equipment can vary greatly.

In fact, the depth indicator is a very important factor when choosing a specific option, so let's consider which modifications are suitable for certain conditions.

Main selection criteria

We strongly recommend that you do not purchase equipment before obtaining a well passport.. With it, you need to select a specific option. This way you will protect yourself from the wrong choice, and if the actual figures do not correspond to reality, the manufacturer must refund you the cost of the equipment.

Voltage and live parts

Units can operate from standard lines as well as from a 380-volt mains, although this is the exception rather than the rule. In addition, it is necessary to check the performance of the optimal voltage because imported models may have other standards that are poorly adapted to our conditions.

Even when deciding which pump to choose for a well of 60 meters or, for example, 55 meters, do not forget to take into account the cable length, because if you do not have 5 or 10 meters, you will have to change the entire cord, connections and extenders in the well are extremely undesirable. Also pay attention to the quality of the shell; sometimes, in order to save, manufacturers use too shaky, and therefore short-lived insulation.

Design features

This is also an important factor, since there are several types of equipment:

• Ground modifications. How to choose a well pump, if the depth of the source is only 7-8 meters? Of course, the ground version of the pump is located on the surface of the earth in a room or in a caisson. Its power allows you to lift water from a depth of not more than 9 meters, this is its main limitation.
• Vibration units will be an excellent option for the suburban area. If you can not decide which pump to choose for a well of 15 meters - the price of deep-seated options is high, and the source is used several months a year, then it is best to pay attention to membrane modifications like “Trickle” or “Baby”. For home, their use is not very justified due to low productivity.
• Vortex pumps are used for deeper wells. The main driving mechanism is a wheel with blades. A feature of this type of design is the ability to use a multi-stage mechanism, so when choosing an option, which pump to choose for a well of 50 meters or more, you need to keep in mind that one step raises water by 50 meters, and each additional step adds another 5 meters.
• Centrifugal pumps at the moment are the most common type of design, they raise the water even from the greatest height. The design is fairly simple and reliable, but it is better to choose products from European manufacturers, as practice shows, they are much safer than Asian counterparts.

Tip! Remember that vortex pumps are very demanding on the quality of water and the content of impurities in it, it is advisable to use them only in sources with very clean water.

Performance

Another very important factor that should not be forgotten in any case. This indicator makes the use of certain types unjustified. For example, equipment such as “Streamlet” has a capacity of about 0.5 cubic meters per hour, which is very small for a house — such a mechanism cannot provide two open cranes.

You can calculate the performance you need with your own hands.

It does not require complex instructions and clever calculations, everything is quite simple:

• Calculate how many taps will be supplied from the well. In this case, do not forget about street watering taps, bath and gazebo, if any. Otherwise, you run the risk of facing a problem of insufficient pump power after the completion of the erection of all buildings.
• The number of end points is multiplied by 0.5, since so much in an hour can pour out of one tap. This value should be taken as a basis when purchasing equipment.

Well depth

As noted above, some types of pumps have a depth limit, so this factor should in no way be overlooked.

All equipment can be divided into the following groups:

• Ground pumping units. They are used in the smallest wells, the depth of which does not exceed 9 meters.
• Vibrating pumps for wells can operate at different depths. And the decision of which pump to choose for a well 30 meters, 20 meters, 10 meters depends on the features of operation and the required power. For one crane, the vibration pump is an excellent solution, especially since the price of this option is much lower than the others.

Tip! Vibrating pump in the process of working very hard against the walls of the well, because of what can break the filter. It is not recommended to use it constantly to avoid structural damage.

• Vortex units are able to lift water from a depth of 50 meters. If this value is greater, additional stages are added to the pumps at the rate of 1 section for every 5 meters.
• Centrifugal variants are different in breadth of configurations and power characteristics, so you can choose an option even to great depths - 100 meters or more.

Conclusion

Which submersible pump to choose for a well is an important question that can be answered correctly only taking into account many factors. This is the only way to ensure that the equipment will last for a long time without breakdowns. The video in this article will help to understand this topic even better.
