Types of pumps for wells

Downhole pumps come in two main types: surface and submersible. Both of them have a number of design differences and are used in different conditions.

Surface

This type of pumping equipment is of four types:

1. Hand pumps. They do not have a motorized drive, they are driven by human muscle power. Indispensable where there are problems with electricity, but not applicable for wells deeper than 8 m.
2. Self-priming pumps. These hydraulic machines for pumping liquid do not come into direct contact with the aquatic environment. A simple electric centrifugal pump is placed on the surface, and a special water intake hose is lowered into the well. Such pumps have a habit of overheating, so it is necessary to monitor the temperature of their casing.
3. Household pumping stations. They are a self-priming pump, which is equipped with a special hydraulic accumulator. This accumulator allows the system to maintain a constant water pressure. Such pumping stations can already be used to organize autonomous water supply at home. However, they can work at well depths up to 10 m.
4. Pump stations with injection elements. Thanks to the built-in injectors, they increase the water pressure. But such hydraulic machines are more expensive.

Submersible

It often happens that the wells from which water is taken are of great depth.Surface pumping equipment is not suitable here. For such purposes, submersible pumps are used. They are also divided into four types:

1. vibration models. Inexpensive devices that allow you to raise the liquid to a height of about 20 m. By virtue of their design, they work due to vibration, which negatively affects the walls of the well. Also, such hydraulic machines can deteriorate due to water with mechanical inclusions.
2. Centrifugal pump units. They are quite expensive, but they allow you to create a high pressure of a liquid that rises to a height of up to 100 m. Due to the absence of vibration waves, they do not destroy the walls of the wells and are not sensitive to mechanical impurities in the water.
3. Screw pumps. They were built according to the classical scheme used by Archimedes. The liquid is pumped into them using a special screw, so such hydraulic devices pump not only clean water, but also viscous liquids. These pumps require constant maintenance and often fail. In domestic conditions, they are practically not used.
4. vortex pumps. This is a modification of centrifugal hydraulic machines. Due to the presence of special grooves on the walls of the working chamber, the liquid is pumped out with a very high pressure. The pumps also cope with gas bubbles in the hydraulic environment, they do not harm them.

What do you pay attention to when buying a surface pump?

In the field of domestic use, vortex and centrifugal models are most widely used, which differ from each other in the principle of operation and in the design of the impeller. In a centrifugal product, the impeller is located on a shaft, the rotation of which is carried out using special bearings. Today on sale you can find products that are a rather complex system that includes several impellers at once - the more there are, the more pressure can be obtained at the outlet of the apparatus.

The impeller of the vortex unit is equipped with inclined or radial blades. Other things being the same parameters, such pumps are capable of delivering significantly more pressure than centrifugal equipment. However, there is one important nuance: such products are able to function normally only in clean water, as they are subject to significant abrasive wear. This means that before entering the pump, a special filter will have to be installed, on which particles of various sizes will settle.

There are designs of surface pumps that are able to take water only if the pumping part and the riser pipe are preliminarily filled with water. Such products are called normal suction pumps. They are filled with a special hand pump. Before proceeding with filling the system, a special plug is unscrewed in the upper part of the device to nullify the action of the check valve, as it will prevent the filling of both the pump itself and the suction pipe.

Self-priming pumps are equipped with a special ejector, which during operation creates an area of ​​​​low pressure, due to which water is drawn. This allows you to significantly increase the efficiency of the equipment. Recently, pumping stations have become widespread. If they are planned to be used year-round, then it is necessary to consider their installation in such a way that the equipment is warm at optimal air humidity. The design itself includes four main elements: the pump itself, a hydraulic accumulator, a mechanical type pressure switch and a pressure gauge. In such equipment, completely different types of pumps can be used, but it is better to give preference to a self-priming apparatus, which greatly facilitates the operation of the system.

The best screw pumps for wells

The principle of operation of such models is based on the action of a screw mechanism. The simplicity of the design determines the low cost and unpretentiousness of such pumps. A feature of their functioning is the creation of high pressure at low productivity. Screw pumps are used in shallow wells with low flow rates.

What are the parameters for choosing a pump for a well

As a rule, the owner must know to what depth the well was drilled and its diameter, the selection of the pump largely depends on this. If the owner decided to drill a well on his own, then it is recommended to determine these criteria in advance, but when the work was carried out by a specialized organization, these data are indicated in the well's passport.

Installation of a deep well pump.

Most pumps are designed for wells with a diameter of 3 or 4 inches (1 inch equals 2.54 cm), with the choice of the latter being much larger.

Based on the parameters of your source, we determine the following criteria:

1. Water level.

What pumps are best for a well? The characteristics of the pumps must indicate the immersion depth of the unit, there are devices that operate only at a depth of up to 9 meters, and there are those that raise water from 50 meters.

If you do not know the height of the water column of your well, then you can determine it yourself using a rope with a load at the end, lowering the device into the hole to the bottom. Then it remains only to measure the dry and wet parts of the rope: the first number will show the distance from the surface to the water table, and the second - the height of the water column.

If the depth of the well is known, then it will be enough for the load to submerge a little in the water. Then it is enough to subtract the footage of the dry part of the rope from the total depth to get the height of the post.

1. Well flow rate.

Each well produces a characteristic amount of water only for a certain period. This mass is called debit. The desired parameter is determined as follows: the time is recorded for which the water will be completely pumped out of the well, and then the recovery time of the water column. Dividing the second number obtained by the first, we obtain the desired characteristic.

I must say that the data calculated in this way are quite approximate, but they will be enough to select a pump.

1. Performance.

Performance is an important factor when choosing a pump.

If you have not yet decided which pump to choose for the well, then pay attention to the performance of the unit. This factor directly depends on the owner's water consumption.

It is necessary to determine what functions the device will perform - serve only for home use or also for watering the site

This factor directly depends on the water consumption of the owner. It is necessary to determine what functions the device will perform - serve only for home use or also for watering the site.

The gradation of water delivery from modern pumps is wide: from 20 to 200 liters per minute. It is estimated that one person consumes about 200 liters per day, then for an average family of 4 people a pump with a capacity of 30–50 l / min will be enough.

If it is planned to water the site (and this is approximately plus another 2000 liters per day), then the unit should, accordingly, produce more water. So you need to choose a pump with a capacity of 70-100 l / min, of course, the price of such a device will be an order of magnitude higher.

Table for determining the flow

1. Head.

Not only should a properly selected pump uninterruptedly deliver the right amount of water, but also the pressure should be such that the liquid does not flow in a thin stream, but in a normal stream, which will water the garden and serve household appliances.

The calculation of this parameter is easy to do with your own hands: the depth of the well is taken in meters, 30 meters are added to this number, it turns out the height of the water column, which the unit must master. For safety net, another 10% of the amount received is usually added.

For example, the depth of the well is 20 m, add 30 m and get 50 m, adding another 5 m (10%), we find the estimated height of the column - 55 m. So, to the question "Which one to choose a well pump with these parameters?", We answer: optimal an option would be to purchase a unit with a head of at least 60 m.

These are the main technical characteristics necessary for choosing a pump for a well

In addition to these, there are several other factors that you should also pay attention to.
