how to choose, types- Review + Photos and Videos The well itself is preferred by most of the owners of agricultural areas as a source of water for equipment and independent organization of water supply. Which type of pump is most suitable in this case and according to which aspects to make a choice - this is the only major problem that we have to solve! We will select an option and find out what is the best surface pump for a well.

First, we need to understand the specifics of using this view equipment, and it is also necessary to point out certain useful characteristics of such products.

How to connect a surface pump to a well - characteristics and various models

Water is pumped by suction through a hose absorbed into the water, with further supply to the place of water intake. The operation of these devices is different from each other.

Common features: versatility in use.

how to choose, types- Review + Photos and Videos When selecting a pump, the well diameter is not a determining parameter. For example, surface submersible pump for well . This is tremendous efficiency. According to this characteristic, they exceed submerged counterparts, as well as their efficiency values.

The limitation in use is determined by the fact that the deepest water intake does not exceed six to nine meters (they do not have enough capacity).

On the Internet it is possible to find articles that describe that such models cannot work with a well. But this is not entirely correct. For the purpose of artesian keys, they are practically useless. However, in a private house, sandstone wells are of prime importance, the depth of which is within the boundaries of six to twelve meters.

Thus, for such moisture keys, shallow pumps are completely suitable. The first is to make the right calculations and choose the right model.

Complete enclosure isolation does not occur. As a result, during installation, you should consider such a question as the protection of the pump from rain. When operating in the process for more than a year, either a caisson (with insulation) is equipped, or the device is introduced in one of the auxiliary rooms (underground, shed, outbuilding).

Small in weight and size. However, for the purposes of almost all owners, the most tempting thing is that the pump is installed on a plane near the well. how to choose, types- Review + Photos and Videos

Firstly, it greatly simplifies visual supervision of the functioning, periodic services (in some models it is taken into account) and, if necessary - service. Secondly, if the product is identified at a place where year-round water supply is not required (for example, a summer cottage), in this case it is not difficult to dismantle it and move it into the house, until the next year. Also, we will not offer any type of shallow pumps or distribute certain models.

Each person decides for himself, in accordance with the criteria for using the product. However, in order for the selection to be correct, you need to understand something about such devices. But still, let's clarify - for a horizontal pump well, only vertical ones are used, since the direction of water movement is upward.

Types of pumps. Well construction with surface pump

Centrifugal surface pump

how to choose, types- Review + Photos and Videos Advantages: are ready to work without failure, even if there was a "airing" in the work, the formation of a "plug".

Disadvantages: in case of strong clogging of water, they quickly leave the mode. As a result of this, the filter of water arriving through the suction nozzle must be supplied in a strict manner. The noise level is the highest than that of analogs.

Self-priming

These are centrifugal, but they have an ejector in their personnel. This helps to increase the efficiency of the product.

If the dumper is internal, in this case it is allowed to raise the water by approximately five to six meters. With its external location, this coefficient increases up to twenty-five to thirty meters. Although such models are not used so often due to the fact that mostly personal buildings do not often happen in more than two floors. The presence of the ejector increases the depth of the water intake.

Vortex

how to choose, types- Review + Photos and Videos Benefits: are able to form the greatest pressure in the system than previous models (from three to seven times), since it is stronger than centrifugal ones.

It is reasonable to operate if the length is quite long. Much less noise. Disadvantages: as a rule, efficiency is less than forty-five percent. They terribly dislike the suspensions contained in the liquid, as a result of this, they thoroughly work only with the absolutely purest water. In this regard, they are the most "harmful".

For this reason, an especially effective filter must be provided. From this it follows that it is necessary to endlessly monitor the state of the well and more often to clean it from siltation provisions. The choice does not have the ability to do only with the selection of established industrial characteristics. In addition, it is necessary to aim at the characteristic features of the implementation of a particular model and the specifics of operation.

Installing the surface pump on the well

Body base

how to choose, types- Review + Photos and Videos Perhaps it is still plastic, stainless steel or cast iron.

Obviously, initially, this safety of manufacturing is not significantly comparable, however, when the pump is determined according to all the rules and instructions, then such manufacturing is more correct, since it weighs less and the cost is lower, the temperature of the pumping water (for plastics, the maximum is up to fifty degrees Celsius), since warm water from wells does not work.

Productivity

The calculation must be made "to the maximum". That is, is a certain pump capable of supplying water at the same time to all points of water intake (in a situation that all taps are open) without a sudden decrease in its pressure.

The created head

This was partially stated earlier. Consideration should be given to the specific configuration of the water main.

Choosing a location for installation

Surface pumps are permanently installed on land - under no circumstances should water get into the unit housing. Perfectly, the pump should be installed as close to the well or to the well as possible. Accommodation must be dry, relatively hot (with a positive temperature) and well ventilated.

It is likely that a pumping station will be installed in the basement, but in this case it is necessary to accept the continuous hum. To place the apparatus close to the well, not very large structures are built or equipment is placed in caissons located underground - concrete, plastic or iron insulated buildings with ventilation, equipped around the casing of the well.

Caissons are built below the freezing level of the soil. In this case, water pipes to the dwelling are laid in a trench, in addition to the earth dug in non-freezing layers.

Connecting a surface pump to a well

how to choose, types- Review + Photos and Videos Before connecting a shallow pump to the water supply, it is fixed on an immovable formation supported by bolts. In order to neutralize pulsations, it is recommended to use a rubber mat or specialized foot nozzles as a pad. A hydraulic hose is connected to the outlet, to the other side of which an opposite valve and a special filter for hard cleaning are connected, sealing the assemblies with a special tape or linen.

Outgoing pipes, the main ones to the water supply, are connected to another outlet, located in the upper part of the body. The opposite valve is immersed in some water, providing a small slope in the direction of the pipe or hose coming from the valve to the pump.

In the next step, the system is filled with water through the emerging holes or through the filling plug. Significantly free all airspace from the system! Then connect the pressure head with wiring through the housing. At this stage, the filler hole is closed and the pressure in the tank is checked.

If the pressure innumerable corresponds to the one confirmed in the instructions, pump it up with a pump or lower it. Specifically, having done all the steps, the equipment is inserted into an outlet and started. The introduced pump must start working and fill the system and hydrophore with water. Turning off the motor indicates that the pressure in the system has reached a maximum (from one and a half to three atmospheres). how to choose, types- Review + Photos and Videos

Now it is allowed to open the crane and make sure that the structure is working.

When, when the valve is open, the pressure does not meet the characteristics written in the instructions, the relay operation should be adjusted.

Installation features for other water supply structures

Even after reading the advice about this, how to correctly determine a shallow self-priming pump into a well or well, difficulties may arise when turning on the equipment to other keys. These recommendations will be needed for the one who exactly plans to automate the supply of water from a column or a storage barrel.

Connecting an electric pump to a column, it is worth thinking about how to connect a shallow pump to a column, not too late, including in consequence of the design of the hand pump. It is recommended not to disassemble the manual control, but to replace it with automation.

In order for both devices to function, it is necessary to cut under the rear valve of the dispenser, identify the part with the revolving valve and connect the pump through an iron pipe. It is more correct to change the opposite valve on the column, or install one on the tee to prevent air from sucking in from the edge of the column. A spherical rectifier is cut in between the hand pump and the nozzle.

how to choose, types- Review + Photos and Videos The rule of operation of the combined column is elementary: first, a column is raised with a hand pump larger than the ball valve, then it is blocked off and the pump is started. It is essential that there is always water in the "glass" of the column; if necessary, it must be added without fail.

The gap is assumed for which the pump will lag behind the well. The depth of the water intake is reduced by approximately two and a half to three percent based on one meter of the gap. In other words, the greater the length of the line, the more the pump will be able to draw water from the smallest depth, and vice versa.
