Choosing a pump for a deep well. How to choose a pump for a well: recommendations for choosing pumping equipment A well of 30 meters, what power does Aquarius need?

The operation of a well is impossible without the use of a mandatory component of its arrangement - a pump. After all, a bucket is absolutely not suitable for collecting water from a narrow trunk. In addition, lifting from the depths and transporting water manually would take too much effort and time. I don’t want to waste either one or the other, do you agree?

Properly selected pumping equipment will fill containers in a bathhouse, home, or garden in a matter of minutes. Now it is possible to purchase equipment to service an object of any size. On its basis, you can easily build an automatic water supply system that does not depend on centralized supplies and the participation of owners in the pumping process.

We will tell you in great detail how to choose a pump for a well, what the future owner of the device needs to take into account and provide. A scrupulous explanation of important points for the user is supplemented with photos and video guides.

Before purchasing a suitable pump for a well, you need to clarify a number of indicators of your structure:

  • static level;
  • dynamic level;
  • flow rate;
  • bottom base mark;
  • pipe diameter.

Which pump to choose for a 30 meter well

Today we will pay special attention to wells with a depth of 30 meters, which are quite common, and will select the best well pump according to its characteristics. Exactly the one you need.

You can read the general article on pumps, perhaps there you will learn something new and interesting for yourself.

And all our articles on pumps are waiting for you, the collection is constantly growing and expanding, there will be even more of them soon. In the meantime, we move on to choosing a pump.

How to choose a pump for a 30 meter well

Having completed the drilling work, the team of workers left you a 30-meter well, and among a huge variety of submersible pumps, you need to choose the one that suits your parameters. It's not as difficult as it might seem. The drillers should have given you a passport for the well and there are recommendations on the correct selection of the pump. Following the directions in the data sheet, choose what suits you and everything will work well.
You weren't given these recommendations?
Then we will now select a deep-well pump for a 30-meter well according to the data you have.
Let's find out the diameter of the pump; for this it is important to know the diameter of your casing.


Here is a small plate that will help you decide on the diameter of the pump:

Note! 4" submersible pumps can have different diameters, ranging from 98 to 105 mm. To save money, workers sometimes install narrow 98 mm pumps in a 117 mm plastic casing. The internal diameter of this pipe is 101-102 mm, which means this pump can be squeezed in there. Plastic has the ability to bend, contract and expand, change shape, in other words. This leads to the fact that, in the event of a breakdown, a 4-inch pump made of HDPE 117 mm pipes you won't be able to get it. It will work for 5-10 years, during which time you will lose the warranty and will have to drill again.

We’ve decided on this, let’s look further.
Most water pumps are labeled with two characteristics: pressure and performance. For example, the popular Grundfos SQ 2-70 tells us that its productivity is 2 m 3 / hour and it can produce these 2 cubic meters from a depth of 70 meters, 70 is its pressure. Knowledge of these parameters will help us choose the right pump for a 30-meter well.
It is important to understand that the performance of your pump should not be more than 90-95% of the well's flow rate.

Water pump for a 30 meter well for irrigation

Not everyone needs to bring water into their house; for many summer residents, a simple summer arrangement is enough to water the site and water outside. Such wells do not need powerful and expensive pumps; a completely ordinary one will suffice.
Now we will find out what kind of pump is needed for a 30-meter well for irrigation.
You should know that a submersible pump is selected not by depth, but by dynamic water level in the well. This is the lowest possible water level during pumping.
We don't know your dynamic level, we will take it as 23 meters. You should know the exact level or just look at the well's passport.
If you have dynamic level about 15 meters, then take the pumps from this article.
At dynamics of 10 meters or less, this material will help you.
So, let's say you need to lift water from a depth of 23 meters. This means that the required pressure must be 23 meters for the water to rise to ground level. Plus, we need a pressure of at least 2 atmospheres to make it comfortable to use (1 atm = 10 meters of pressure).
In total, the required head is 43 meters. We select...

Well flow rate is 1.5 m 3 /hour.
It is very likely that you have a sand well, the following models will suit you:

  • Aquarius 0.32-40U
  • Gilex Vodomet 40/75
  • SPERONI STS 0519 or SPS 0521
  • Grundfos SQ 1-50 (3 inches)

Well flow rate is 2 m 3 /hour.
For a 30-meter well with slightly higher productivity, these models are suitable:

  • UNIPUMP ECO 1
  • SPERONI SQS 2-45 (3 inches)

Well flow rate is 2.5 m 3 /hour.
A small capacity limestone well goes well with the following pumps:

  • Aquarius 0.5-50U
  • Gilex Vodomet 55/75
  • SPERONI STS 1010
  • UNIPUMP MINI ECO 2 (3 inches)
  • Aquario ASP 1C-60-90 (3.5 inches)

Well flow rate is 3 m 3 /hour.
This is a typical flow rate of an artesian well in the Moscow region. Here are the optimal pumps for it:

We calculate the pressure: we need to raise water from a depth of 23 meters to ground level, this is equal to a pressure of 23 meters, the height of the tap from the floor is another 1 meter, already 24 meters. The water pressure in the tap should be 3 atm, as we know, 1 atm. = 10 meters of pressure. 24 + 30 = 54 meters. And we will add 20 meters as a reserve so that the pump does not work at its limit and is less strained. Also, these 20 meters include various losses. Total, 54+20 = 74 meters- this is our pressure for a 1-story house.
If you have a two-story house, then you need to add another 3 meters to raise the water to the 2nd floor.
Pressure for The 2-storey house will be 77 meters.
The difference is small, so the same models will fit.

If your home is located in SNT, then there is a high probability that you have voltage problems. This does not allow the pump to develop the required power and an additional 20 meters of reserve will be very useful!

Below we have collected the best pumps for a well 30 meters deep. In our experience, they have the highest quality in their price range.

Well flow rate is 2 m 3 /hour.

Well flow rate is 2.5 m 3 /hour.
This is a well with low productivity and the following models are suitable for you:
It is very common to use a vibration pump like Malysh in a well 30 meters deep. Unlike the centrifugal pumps that we wrote about above, they cost only 2000-3000 rubles. Therefore, after reading the theorists, summer residents often buy a Malysh pump for the first time. Due to its vibration, it constantly muddies the water, slowly breaks the well, or completely breaks away and falls. We periodically receive calls asking us to get a vibration pump out of a well, but we have to pay 30,000 rubles. Few people want to pay for moving equipment...

You should not use an external pump in a 30-meter well, or in any other one either. Its price is not much lower than the Aquarius BTsPE or Vodomet, and the noise, capriciousness and limitation in dynamic level make the pumping station a useless purchase. If your dynamic level is more than 6-7 meters, then your surface pump will physically not be able to lift water from the well.
Choose an inexpensive but proven submersible water pump. Above we described all the best models.

Pump for depth 30 meters

You can gain independence from tap water if you drill a well on your property. However, aquifers can be located at different levels, so deep-well pumps for them are selected individually. Traditionally, at home, drilling limits are 20, 30 or 50 m. Less often, specialists “go” to lower horizons.

After the water hole is formed, based on its parameters, hydraulic equipment is selected. For popular depth ranges, domestic and foreign manufacturers produce a wide range of modern pumps, so the question of which pump is best for a well remains relevant.

Selection by technical parameters

From a depth of up to 10 m, pumping can be carried out using a surface water pump. At great depths, the following types of deep water pumps are used:

  • vibration;
  • centrifugal;
  • screw;
  • vortex.

Due to the fact that the device is located below the liquid extraction level, the housing is not subject to overheating. An increase in temperature is a disadvantage that characterizes a surface well pump. This factor has a significant impact on the overall period of operation.

When choosing equipment, take into account the following parameters:

  1. Water level and shaft depth to the mirror

This indicator is one of the first indicated in the technical passport. If you don’t know what depth you need to purchase equipment for, you can measure it yourself. To do this, you will need a rope (preferably twine, it gets less wet), on which knots are tied every meter. A weight is tied to the end of the rope and lowered into the pipe until it sinks. Next, simply measure the distance from the edge to the surface of the water.

In exactly the same way, the water level in the source is determined, this time by measuring the wet part of the rope.

  1. Water requirement - average

This parameter depends on how often the liquid is used in the house. If only for the personal needs of people, it is assumed that a person on average consumes 180-200 liters per day. A family of 4 people will consume, respectively, 1000 liters per day, which means the pump power must be at least 30 liters per minute. Even such a simple model as Malysh and others like him can cope with this task. If for irrigation, then another 2000 liters are added to this indicator (for a plot of 6 acres), accordingly, the power increases to 80-100 liters per minute.

  1. Well debit

These readings are also obtained experimentally. To do this, they first determine how long it takes to empty the entire source, and then how long it will take for it to fill to the maximum. Divide the second by the first indicator among themselves and receive a debit.

  1. Pressure (water column height)

The devices are selected according to their dimensions and technical characteristics, because if you take a pump for a 20-meter well, which operates in relatively gentle conditions, then it should produce a pressure close to 2 atm. for water supply. The calculations also take into account the error associated with losses in the pipeline, taking it at the level of 10%.

  1. Shaft diameter

If water was extracted by drilling with a professional installation, the diameter was indicated in the passport. If this is the result of your work, measure with a ruler and determine the distance between the edges of the casing in inches.

Most domestic equipment is designed for 4 inches (10.16 cm) diameter. If possible, a casing string of exactly this diameter is installed in the mine.

This includes not only the cost of the equipment itself, but also components - cables, automatic machines, etc.

VIDEO: About choosing a deep-well pump

How to correctly calculate the pressure

As a result, we calculate the required pressure that a potential pump must have.

  1. The mine is 20 m deep.
  2. The required pressure is 2 atm, which is comparable to 20 m of pressure.
  3. The device is installed at a level that is 4 m above the bottom.
  4. The working pipeline is 40 m long.

From the calculations we get the result: (20-4)+(20)+(40*0.1)=40 m.

The range of devices with pressures up to 50 m includes the following popular models:

  • Unipump (Russia, China) - up to 10 thousand rubles.
  • Belamos and Vodomet (Belarus, Russia) - interval 12-16 thousand.
  • Aqario (Italy) - more than 20 thousand rubles.

For a well 30 meters deep, the pressure is calculated using a similar method. Let's give an example based on the most common input data. We will suspend the pump for a 30-meter well in such a way that there is about 5 m of depth left to the bottom.

  • Working depth 25 m.
  • Pipeline to the sampling point 40 m
  • The pressure is 3 atm, which is comparable to a head of 30 m.
  • The difference in levels is 5 m.

We carry out calculations: (30-5)+(40*0.1)+30+25=54 m.

In such conditions, for wells 30 meters deep, it is necessary to focus on models capable of delivering a pressure of at least 54 m. At the same time, the devices should not operate at the limit of their capabilities, but they are selected with a power reserve of 15-20%.

The best pump models for a 30 meter well

Based on the internal diameter of the casing pipe, which is usually in the range of 100-125 mm, it is worth paying attention to the following specimens:

Grundfos

The Danish brand offers products with small diameters and high performance. The price tag for popular models will be about 40-50 thousand rubles, which significantly exceeds the cost of Chinese analogues. However, the costs are offset by high reliability. The three-inch model SQ2-85 is capable of delivering a head of a little more than 100 m (you can even use such a pump for a 50-meter well), with a flow rate of 2 m 3 per hour. It is easy to select a pressure of 70-75 m, where SQE 2-70 or S3-55 dominate.

Pedrollo

Well pump Pedrollo 4BLOCKm 6/4

The Italian brand is represented on the domestic market by units over 100 mm in diameter, which allows them to be used in most 5-inch wells. One of the popular models is Pedrollo 4SR4m/14-P. You can find it in stores for 25-26 thousand rubles. The design includes a check valve and automatic shutdown during dry running. It works not only at 30 m. Thanks to a pressure of 88 m, this pump for a 50-meter well will also “pull” with the correct calculations. The liquid flow rate will correspond to 4 m 3 per hour.

ZDS

The Italian manufacturer offers high-quality four-inch devices at affordable prices. One of them is QS4P.2-12, equipped with a control panel. The retail price is about 15 thousand rubles. Italian well pumps are highly resistant to abrasive particles and are also equipped with protection against overheating. The average pressure is 77 m, which, with a flow rate of 2.4 m 3, allows the unit to be installed on water levels of about 30 m without exceeding the load.

The best pump models for great depths

Water horizons greater than 30 m require special parameters for devices. For those who do not know which pump to choose for a 50-meter well, it is recommended to pay attention to the additional characteristics specified by the manufacturer. It will be necessary to ensure a minimum content of solid particles in the water. The acceptable parameter is indicated in the instructions or data sheet from the manufacturer.

Lowara

Italian well pumps are equipped with reversing valves. The permissible maximum abrasive content is 100 g/m 3 . The current series are Z6 and ZN6. The outer casing is made of stainless steel. Their cost is 25-28 thousand rubles.

TWU

The German manufacturer presents a multi-stage submersible pump for a 50-meter well. It is recommended to use for conditions not exceeding the abrasive parameter of 50 g/m3. The design has a built-in thermal relay. The devices have radial or semi-axial impellers in a sectional design. The corrosion-resistant motor has a high degree of protection against liquid penetration. The stator is completely sealed and impregnated with a special resin. The device is cooled by the pumped liquid. The motor can only be operated while immersed.

SPRUT

Models of this brand pump out liquid from wells with minimal contamination. The diameter of the casing pipe must exceed 100 mm. The devices are used to irrigate the site and supply water to the house. A popular unit is the 4S QGD 1.8-50-0.5kW, which has an outer diameter of 4 inches. At the end there is a dirt filter that does not allow particles larger than 1 mm in diameter to pass through. Its cost does not exceed 5-6 thousand.

Taking water from depths of 100 m requires the use of more demanding equipment. In this case, the savings will be ineffective, so you should not use budget models from Chinese or Russian manufacturers. The most popular are Pedroll and Grandfos. They are capable of working for a long time in such conditions, delivering a pressure of more than 150 m.

Optimal diameter

To expand your options for selecting pumping hydraulics, you must pre-drill a hole for depths greater than 20-25 m with a diameter of at least 5 inches (125 mm). A casing pipe with a wall thickness of 5 mm will be lowered inside. Accordingly, for these parameters, a pump with external dimensions of 4 inches will be relevant.

VIDEO: Review - Which submersible pump for a well

To create a year-round water supply for a country house, wells are most often used. Water is pumped out of them using pumps. Equipment is selected depending on the depth and nature of the source. So, sand often requires a pump for a 30-meter well.

Water in the soil is located in layers, the location of which is determined by the placement of rocks. Groundwater and perched water are closest to the surface. Typically, it is these water reserves that are used by wells and Abyssinian wells. The purity of such water is questionable. It is better not to use it as drinking water in densely populated areas, when agricultural complexes are located nearby, and in some other cases.

Rice. 1 Location of aquifers

The next layer is the sand horizon. It is located much deeper, usually at a depth of thirty to fifty meters. While water seeps from the surface, it is purified. Sand wells can be used as drinking sources, but the supply of water in them is not always large.

Even lower, at a depth of fifty meters, there is an artesian layer. It passes through limestone rocks and is usually the purest.

Types of pumps for wells

All pumping equipment is divided into surface and submersible. Surface installations are not sealed, so they are located in rooms, caissons and other protected places. These pump options lift water from a depth of up to ten meters. Ejectors help increase this parameter.

Another large group of units are submersible pumps. They are immersed directly in water. Such devices have a sealed housing, high performance and can lift water from significant depths. Their main disadvantage is sensitivity to contamination and difficulty in maintenance.


 Rice. 2 Downhole devices

Submersible well pumps usually come in the following types:

Centrifugal

Are the most popular. The movement of water is carried out due to the rotation of the paddle wheel. It creates a centrifugal current, throwing liquid towards the walls. As a result, it leaves the working chamber under pressure. To create the necessary pressure that lifts water from a depth of tens of meters, one wheel is not enough, unless it has a significant diameter. That is why a centrifugal pump contains several working chambers at once, which successively increase the pressure.

When choosing a pump for a 30-meter well, you must be aware that your main task is to achieve a correct and uninterrupted water supply. That is why, when choosing a pump option, it is very important to take into account the depth of the aqua well. Each depth has its own recommendations for choosing equipment and you need to listen to them.

Which pump is best for a 30 meter well? The above depth parameters are suitable for the use of both surface and submersible pump options, with manual or fully automatic equipment mode. Each of these options has its own characteristics and has a number of advantages.

Submersible water pump for a 30 meter well and its advantages

This equipment option has high power ratings. During its operation, it can be completely or partially submerged under water. With its help, you can establish water supply for both domestic and agricultural purposes, irrigate the area, and water it. These pump options have a reliable protective housing that eliminates the possibility of water getting inside the device. Effective motor cooling is the key to their long operation.

Based on how clean it is and how much sand it contains, you can choose the vortex, screw or center options.

Vortex pump options are distinguished by a minimum performance indicator.

A screw pump for a 30 m well can be used to supply water not only from an aqua well, but also directly from an open reservoir. What is attractive about this option is its affordable price.

If we are talking about a method for extracting water from a well that has a lot of sand, or it is necessary to pump water from other water wells, then it is better to use a centrifugal pump for a well for this purpose (for a depth of 30 meters, this is the best option).

Surface pump for a well 30 meters deep

The design features of this equipment option suggest the possibility of placing its body at a distance from the place where water is pumped. Initially, models of such pumps are not designed for use in deep water wells.

Determining the best pump for a well 30 meters deep

Having familiarized yourself with the characteristics of different types of equipment and learned about their advantages, it will be easy to make a choice in favor of one option or another. And if in the question of how to choose a pump for a 30-meter well, you will also pay attention to two important parameters of the pump’s operation, such as:

  • declared performance,
  • force and intensity of pressure,

then you won’t think long about what kind of pump you need for a well 30 meters deep.
