Pump for the well: submersible on water, how and what to choose for 30 meters, which brand to choose a water

A well pump is the main component on which all the work of the drilled depends. Which options should I pay attention to when choosing a pump for a drilling well?The price of the equipment for the well is not low, so it is necessary to select it with special attention. How to choose the pump for the well is correct, more below.

Characteristics of surface pumps for a well for water

A well pump is one of the main components of a systemWater supply. Types of pumps for wells can be very different - surface( top), submersible, vacuum, etc. It is necessary to consider the types of pumps a little more so that any consumer, even if he will equip the well with the help of professionals.

It is necessary that the buyer not blindly trust them, but also in general understand what options are better to be considered as suitable for the prepared well equipment.

Since it is necessary for the owner of the well to spend money, it is necessary that the finances spent be maximally effective. Below is an overview of the equipment that has been used for many years and received positive reviews.

There are several types of well pumps

In addition, surface equipment:

• Not convenient;
• Very noisy;
• Moody at work.

An external pump for full and serious water supply of housing is not suitable, and there is no point in describing them in detail. Surface pumps for the well have a noticeable minus, because of which they are not suitable for many wells in a large number of cases, because the equipment is installed on the surface near the drilling site, and the suction height of the water must not be less than 8 m even with the pump running( dynamic level)That is, the initial level, not disturbed by pumping or pouring the level, should be even greater. And not every well has such data.

Types of submersible pumps for wells

Submersible well pumps can be vibratory, vortex, screw( screw), centrifugal. Water vibrating pumps( such as "Malysh", "Rucheyek") are of low price, the most economical option. Using the equipment is not difficult, but to supply the house, it is not suitable for a number of reasons. Used mainly by gardeners, truck farmers, as a borehole pump for watering landings.

Vibration, based on the functioning of this type of equipment, adversely affects the very well.

In addition, such moments as the primitive connection of a hose with pumping equipment with a clamp creates serious accidents in the well, if an interruption occurs. Such accidents occur when pumps are used in the construction phase of the house, as temporary supplies of water for construction purposes. Departure drilling crew to eliminate the accident will be expensive. So are the risks justified?Conclusion one, to apply the vibrating pump is rational only in 2 cases: for pumping water from the basements that flooded, and when building foundations or digging wells to reduce the level of groundwater, and to pump water from a water body.

For housing, it is better to supply one of the remaining types of equipment:

• Vortex;
• Screw;
• Centrifugal.

Let's figure out which devices are best to choose which pump has the highest rating. Vortex equipment has no complex structure and is quite cheap. The principle of its work is as follows: the impeller during rotation creates a "tornado" from the water. The speed and power of the fluid in the vortex is several times higher than that of centrifugal pumps with roughly similar impellers. The design of the impeller of this type of equipment is such that it creates the strongest head, because the number of stages of the vortex pump is only 1-2, so the gap between the body and the impeller is at a minimum.

It's easy to use the submersible pump

This feature makes this equipment very sensitive to even minor mechanical impurities in the liquid, and where they are not. As a result of the clog, the impeller breaks down, and in order to do it, it is necessary to dismantle the pump, this causes discomfort and money costs for the work of the masters, so in practice this type of pumps is not used.

Screw equipment functions as follows: auger( screw), rotates in the profile cage. Between the screws and the clip there are special chambers filled with water, they move when the auger rotates along the screw axis and the cage - so the water moves. The pump can be made of metal or polymer materials. Such equipment can be used in the industry for pumping chemicals and viscous solutions, as well as in construction for pumping very dirty water( when pumping groundwater and supplying special solutions).

The screw equipment has rather low efficiency. The use of equipment to pump water from the well is entirely acceptable, but there are the most efficient downhole devices - submersible centrifugal pumps. The deep centrifugal pump for sampling wells is best suited for home and garden areas. Such equipment has the highest performance characteristics. The device has several steps of impellers, which are located on one shaft. During operation, water flows from the outlet of one step to the inlet of the other. So, the head depends on the number of steps of the device. The main parameters, when choosing a pump, is the head and efficiency of the device. If you choose a smart and efficient pump yourself, it's more appropriate to contact a professional, he will help you choose the equipment of a suitable brand.

Description of the centrifugal pump for the Grundfos

Well, if such an aggregate is required that would not cause problems to the owner, and to live in the house was comfortable, then for such purposes a Danish pump "GRUNDFOS" is needed. This pump received a maximum of positive feedback. The first thing to be divided into 2 categories of consumers: those who will use the equipment all year round and those who will simply water the garden in the summer.

The first unit is required:

• Durable;
• Durable;
• Reliable.

Grundfos has a number of protective devices, as well as a check valve, which is needed for water supply systems. Because the diameter of the device is small, it can be used in small diameter boreholes.

The centrifugal pump for the Grundfos well received the most positive feedback

But despite all the advantages, experts say that the check valve works on the pump is not so good, therefore they recommend not to carry out unnecessary work, Immediately install another check valve, despite the fact that the price of equipment will be higher.

As practice has shown - it still has to be done, but it will be necessary to dismantle the equipment, which will cost much more. And another relative disadvantage is the high price of equipment, therefore, when choosing a pump to pump water, you need to calculate the costs, weigh the pros and cons.

How to choose a pump for a well:

brands Now you should consider what equipment is better to purchase, from which manufacturers, what to look at based on the experience of specialists. Today in the market you can see many models from different manufacturers and it's wonderful.

It is important to understand that many popular brands are imported from China, but it is necessary to fence oneself from products and components made in an artisanal way.

There is always a choice - pumps are economical, unknown brands collected in China, and there are well-known and expensive models. It is necessary to carefully approach the selection of criteria and brands, otherwise the budget and water supply on the site will suffer.

Well pump must be of high quality

Products from China can be:

• Defective;
• Resistant;
• Unreliable;
• Short-lived.

If a person does not want to conduct experiments and check the rating of unknown devices, then it's better to pay attention to submersible pumps "Grundfos", "Speroni", "Speroni SPS".Of the budget options, the "Aquarius", "Vodomet" and "AQUARIO" pumps have proved themselves well.

Which pump to choose for the well 30 meters and other depth

Which equipment is suitable for the well 30 m?It is difficult to pump water from such a depth, which requires mounting no less than 2 check valves. To pump the liquid from a serious depth, the equipment is mounted directly into the drilled well. Depth pumps have a small size, but it's enough. A submersible centrifugal pump is suitable for a well. It's good to buy a deep pump.

For a well, it is best to choose a submersible centrifugal pump

If a pumping station is used, it should include:

• Hydraulic vessel that operates under pressure;
• Self-priming pump;
• Original relay.

For a 30 m well, it is necessary to calculate in advance the power of the device needed to supply liquid from a given depth. For this it is necessary to take the depth of the well in meters, to add to it 30. This will be the height of the column of water. To the received figure it is necessary to add a stock of 10%.For a well of 20 m, it is necessary to choose a submersible equipment, better than a centrifugal type.
