Which pump is better for a well: general requirements for units and tips for choosing

Manufacturers

It is very important to focus not only on purely technical points and general descriptions, but also take into account the characteristics of specific manufacturers. Among Russian firms, it is better to choose products of the Dzhileks brand, which have long established themselves on the positive side

Makita products also occupy significant positions in various ratings. For example, submersible clean water pumps PF0300, 0800.

The body of the two models is made of strong plastic, and a double layer of rubber in the gasket increases the life of the motor. The float is controlled by an adjustable lever. The handle with which you need to carry the pump is not only strong, but also comfortable for people. The liquid outlet pipe is made in size 1 ½.The water ingress protection of the housing complies with the IPX8 standard.

Both pumps are connected via a power cable 10 m long and can pump water containing suspensions no larger than 0.5 cm. The permissible heating of the liquid is a maximum of 35 degrees, the depth of loading into water does not exceed 5 m. a water mirror with a thickness of 2 cm or more. Modification PF0403/1100 differs significantly from the products described above. The difference is already expressed in the fact that the body is made of steel, and the outlet pipe has a diameter of 1 ¼.

Talk about Italian well pumps cannot ignore such a popular brand as Pedrollo. The NK version can feed up to 7.2 cu.

m of water per hour (in other words, 120 liters in 60 seconds). The pressure generated reaches 80 m.

In this case, it must be taken into account that the device cannot be used:

• at a liquid temperature of 41 degrees;
• at a sand concentration of more than 0.05 kg per 1 cu. m;
• if necessary, lower the device 20 m below the water surface;
• for continuous liquid extraction.

The firm is ready to order to complete the pump with various electric cables. Individual reconfiguration to a non-standard mains voltage or to a frequency of 60 Hz is also allowed. By default, the delivery comes with a wire 20 m long, the warranty period is 24 months. Another model of the company - Top Multi-Tech can also supply 120 liters of water in 1 minute, but it creates a pressure of only 42 m. At a pressure in the line of 1.5 bar, a restart occurs.

The mains power cable is 10 m long. An electronic device is built into the system that allows you to automatically open and block the water supply.Pumps of this type can only pump clean water, high efficiency and reliability ensure comfort. It is impossible to immerse the pumping device deeper than 10 m from the highest point of analysis. Permissible presence of solid particles (suspension) no more than 0.13 cm in diameter.

Criterias of choice

Before buying pumping equipment for a well, they are guided by the following technical characteristics:

• power. It is directly related to the performance of the device (the amount of fluid pumped per hour or minute). The optimal indicator is 0.8-1.0 kW;
• head. It should provide a rise in water to a height of about 50 meters;
• performance. It is necessary to select a specific model in accordance with the existing tasks. For watering the garden, a unit up to 0.6 m3 / hour is enough. If the device is used for water supply purposes, a more powerful version will be required;
• manufacturing materials. The main requirements for them are resistance to wear, corrosion and mechanical damage. Practice shows that stainless steel and composite materials are optimal;
• automation. It allows you to timely turn off the unit when there is a threat of overload or when the water runs out;
• type of water intake (upper or lower). The latter option can be chosen if there is no risk of severe siltation during the operation of the well or well. Devices with an upper intake are more reliable, but their disadvantage is that when a certain water level is reached, they turn off.

Consider the main types of well pumps.

Vibrating - the most inexpensive option for a water pump. Budget hydraulic machines have a simple device. The absence of rotating parts makes them reliable to use.The vibration device does not require complex repairs and maintenance. The element that drives the pump is not an electric motor, but an inductor. The armature, which is driven by a magnetic field, transmits momentum to the piston and the elastic membrane. In this case, the piston begins to move back and forth, drawing water into the working chamber, and then pushing it into the pressure water line. Such pumps have low power, are demanding on water quality.

It is important that the device is equipped with automation. Otherwise, you will have to buy it additionally.

Screw. As a well, such devices are used infrequently. The main working element of such a device is a screw mounted on a shaft. It is powered by an electric motor. In this case, the auger captures the input that comes from the inlet and distills it towards the pressure pipe. Advantages of the screw version:

• creating a good fluid pressure;
• minimal noise;
• the possibility of using for dirty water with impurities of large sizes, as well as for viscous media.

Cons - low efficiency and productivity. A large number of friction units leads to rapid wear of parts, which means that frequent repairs and regular maintenance are needed.

Centrifugal. The most common option for a summer residence or a private house. A wheel with curved blades is used as a working element. The latter capture the water in the working chamber. Water is thrown to the walls of the working chamber under the action of centrifugal force. Under the action of excess pressure, water is pushed into the pressure line of the water supply.

Advantages:

• powerful pressure, which allows the use of equipment for drawing water from deep sources and wells;
• high performance;
• minimal noise;
• variety of models of deep equipment.

Of the minuses, they note the high cost, the complexity of the device, and a short service life.

Vortex. According to the principle of operation, vortex devices are in many ways reminiscent of centrifugal ones. Due to the design features, not only centrifugal forces act on the liquid. Additionally, the flow receives turbulent acceleration. Thus, the performance of the vortex device is greater than that of the centrifugal one. There are a number of other benefits as well:

• low cost;
• simple construction. The device does not need complex repairs;
• minimal noise during operation;
• Possibility of efficient pumping of water with low air content.

The main disadvantage of vortex-type devices is the high demands on water quality. There should be no solid inclusions in it. In addition, the operational life of such equipment is relatively short.

Principles and Criteria

Buying equipment without thinking about its parameters is not worth it. It won't give the desired effect.

In order to select the right pump, you should pay attention to the following criteria:

1. Power, wear resistance, reliability in operation. To increase the reliability of equipment, modern manufacturers use various design solutions. For example, reputable brands use innovative materials for these purposes. So, bearings are made of tungsten carbide/ceramic. Of course, the consumer is not always aware of what certain parts are made of.Therefore, you just need to focus on brands and choose products from well-known manufacturers. Cheap pumps break down often, and the cost of repairing them is usually comparable to the cost of a new pump.
2. Energy efficiency of equipment, the value of efficiency (the more - the better). These indicators for different models are indicated in the technical documentation, so you can compare them.
3. Availability of additional options. The most important of these are various protection systems. The best models are equipped with several at once. These are protection systems against idle operation (or dry operation, as they say), from overheating, overload, and also from displacement of the impeller (it should not “float” at start-up).
4. The presence of a soft start function. In practice, this means a reduction in the starting current, so that the pump accelerates smoothly during operation. This ensures optimal operation, reduces the wear of the unit, avoids overloading the network, and prolongs the life of the equipment.
5. The compactness of the pump. This helps to reduce installation costs.

Of course, each user may have additional requirements. And the more equipment they match, the better.

Alternatively, a storage tank.

The best submersible pumps for a well

Deep well devices are distinguished by a smaller body diameter, which makes it possible to conveniently immerse in narrow wells. The equipment is in demand in those regions of the country where underground sources lie much deeper, where it is necessary to drill a deep well. They are equipped with high power, which provides the most powerful pressure for pumping water from a depth of up to 75 m. Submersible pumps for wells consumer reviews, expert opinion chose the two leaders with the best performance.

Experts noted that this model has the largest percentage of positive feedback from consumers. They note reliability, long term stable operation, low cost.

Specifics of submersible pumping equipment

According to the type of device, centrifugal and vibration pumps are distinguished. In the first, a rotating disk with blades is used to supply water, and in the second, a special membrane that transfers water with the help of numerous vibrations.These design features are important because they affect well integrity in different ways.

Vibration pump + well: yes or no?

Is it possible to install a vibration pump in the well? These models are relatively inexpensive, easy to operate, and have performance that is suitable for a significant number of wells.

Many experts categorically object to the use of any vibration technique in the well shaft. However, owner reviews report that pumps of this type are used quite successfully without any damage to the structure. So, which pump - vibration or centrifugal - is better for a well?

The objections of experts are well founded. Prolonged vibration exposure almost always negatively affects the state of surrounding objects. The well is no exception.

Vibrations from the pump located next to the filter affect the condition of the casing and the surrounding soil, which are gradually destroyed. Vibration can cause a significant acceleration of the processes of silting and sanding.

But it doesn't happen right away. Typically, wells successfully resist vibration for some time. Therefore, with the help of such a pump, it is possible to pump the well, and clean it, and successfully operate it without visible damage.

But destruction from vibration still occurs, although not too quickly. The constant use of a vibration pump can significantly reduce the life of the structure.

If necessary, the use of vibration models is quite acceptable, but only as a temporary option. But at the first opportunity, such a pump should be replaced with a safer centrifugal device.

Guidelines for choosing a centrifugal pump

To do this, you need to carefully study the technical passport of the centrifugal device and find out several important points:

• what is the performance of the pump;
• whether its dimensions are suitable for the well;
• from what depth can he raise water;
• what are the features of its installation and operation;
• how and under what conditions warranty service is carried out, etc.

Usually consultants give quite professional recommendations when choosing such equipment. It should be remembered that many manufacturers indicate limiting rather than average characteristics for pumps, so you need to take into account some margin of operational life.

Directly in the marking of a domestic pump or in the technical passport of a foreign one, two numbers that are important for choosing are indicated. The first (in example 55) is the flow in l/min, the second (75) is the maximum head in meters

A few words about popular models

If the decision is made to use a vibration pump, most likely, “Kid” or “Brook” will be bought. These models are distinguished by good performance, resistance to breakdowns and quite affordable price.

They are easy to clean or repair with your own hands. But for permanent use, vibration technology is not suitable, it must be replaced as soon as possible.

Vibration pump "Kid" is a popular, but not very suitable choice for a well, since the vibrations of the device can cause its destruction

Among the popular brands of submersible centrifugal pumps, it is worth noting "Aquarius" and "Vodomet". They are very similar, but according to user reviews, Aquarius noticeably wins in quality and durability, although it costs more.

However, the Water Cannon also has its adherents.If you are lucky enough to get a well-assembled model, it will show quite decent results.

Submersible centrifugal pumps of the Aquarius brand have established themselves as reliable and durable equipment for the well, capable of coping with increased loads

Special well pumps will cost a substantial amount, but such costs will fully justify themselves over time. As an example of such a technique, it is worth noting the 3STM2 and 4STM2 models manufactured by TAIFU.

The best vortex pumps for wells

The operation of such pumps is based on the use of an impeller that pumps liquid from the inside of the channel to the outside. Such models create a lot of pressure, are distinguished by the simplicity of the mechanisms, but are not suitable for use in muddy water containing abrasive particles.

Pump selection by performance and pressure

These include the performance of the device and the output water pressure:

The capacity of a water pump refers to the volume of water that it can pump per unit of time. It is measured in liters / hour, or m³ / hour. This parameter shows how effective this device is, for what period of time it will be able to pump a certain volume of liquid. The head refers to the lifting height to which the liquid can be raised using this pumping device.

For drainage pumps, this figure is small, up to 10 meters
Here it is important to take into account the horizontal pressure of water, namely, the task of such pumps is not only to lift the liquid, but also to divert it to a certain distance from the source of accumulation. The performance of the entire device will depend on these indicators.

It is important to consider these two factors when choosing a product, because the device must be operated without overloads, and it is also important to exclude its unjustified switching on and off.
