If you are interested in centrifugal pumps for irrigation, then initially you should familiarize yourself with the design features of this device. This will allow you to understand which model to choose. Inside the body is a shaft equipped with blades. During rotation, a vacuum is created in the central part of the rotor due to centrifugal force, which throws water to the edges of the blades. A new liquid enters the rarefaction zone, after which the cycle repeats.
The technical side should not be too deeply interested, as this will not help in solving issues such as operation and installation. It is important to familiarize yourself with the cost and reviews, which will allow you to understand which models are the most common and popular.
Consumer Reviews
If you are interested in centrifugal pumps for irrigation, then you should read the reviews of customers who have been using this equipment for more than a year. As summer residents note, the convenience of the device lies in the fact that it does not need to be lowered to the bottom of the reservoir. The installation should be located close to the well, and only the hose itself should be immersed in water. Users note that the maximum maximum depth with which water can be drawn is 10 meters. This indicator is enough for watering the territory in the country. Consumers like the device to be lightweight and small, making it easier to use equipment.
Experts advise installing the device on a flat platform, checking first whether there are any foreign impurities or impurities in the liquid. This is because the device is designed exclusively for clean liquid. Some lovers of rural recreation note that the need to shelter a device for pumping water from precipitation cannot be called convenient. For the operation of surface pumps, it is necessary to use a special reinforced hose. It is necessary to exclude the use of rubber, since it is not suitable due to rarefaction. The latter is created during operation, when a soft hose can stop the flow of water at the time of flattening.
Specialist advice
If in the store you are considering centrifugal pumps for irrigation, you should know that after installation the device will create a lot of noise. If you are not ready to put up with this disadvantage, then you can smooth it out by installing the device away from home or in a special room. Before you turn on the surface centrifugal pump, it is necessary to fill in water.
Selection recommendations
If you decide to purchase the described device, which will be used to irrigate the garden or any other territory, then it is initially recommended to deal with some characteristics. This will help to understand whether the equipment is suitable for specific conditions.
The solution to the question of which design to choose (surface or submersible) will depend solely on the depth of the source. If we are talking about deep wells, it is best to choose a submersible model, which will need to be lowered and fixed with utmost care. If we are talking about a depth that reaches 10 meters, then you can use the surface centrifugal option.
Pressure pump selection
If you are interested in centrifugal pumps for irrigation, then you need to pay special attention to the pressure. This indicator is also called the power of the unit. It makes it clear at what distance and from what depth the apparatus will be able to transport liquid. Quite often, consumers do not count with the pressure, therefore, during operation, they are faced with the fact that the equipment is characterized by insufficient pumping intensity. Before choosing, you should know that the head is indicated in meters, while it is important to know the depth of the source from which water will be drawn.
If you decide to choose a surface centrifugal pump for irrigation, then you need to take into account that for 1 meter of vertical lift you will need as much energy as for 10 meters of horizontal pumping. For example, if the well is 4 meters deep, then the pump head should be 7 meters. This indicates that the device will be able to pick up liquid from a 4-meter depth and pump it a distance of 30 meters or less. After you manage to determine at what distance from the well the beds are located, you can find out if there will be enough aggregate with similar indicators. Otherwise, you can find something more powerful.
What else you need to know about power
If you decide to purchase a surface centrifugal pump for irrigation, it is necessary to exclude the operation of the pump at the maximum depth. If a pressure equal to 8 meters is indicated in the characteristics of the device, this does not mean at all that the equipment is suitable for constant pumping at such a depth. This indicator is the maximum permissible. Experts recommend the use of equipment whose pressure is selected with a margin. Otherwise, the unit may not cope with the tasks.
Pump selection by material
If you need a centrifugal pump to give, then it is important to decide what material will be the basis of the design. The worst solution is plastic, followed by cast iron, and stainless steel comes first. If abnormal situations arise , the plastic case or individual parts of this material may not withstand overloads. A plastic impeller is often damaged due to the ingress of foreign impurities. If we are talking about cast-iron elements, then they have a more impressive weight, and are also subject to corrosive processes.
Household centrifugal pumps for irrigation are presented in modern stores in a wide range. If you need such equipment in the household, it is best to choose a design whose body is made of stainless steel. It is corrosion resistant, reliable and lightweight. However, cast-iron housings are cheaper, which is why they are the most popular in the domestic market among consumers.
Choosing a Safe Pump
A centrifugal pump must be safe in terms of protection against power surges. If you want to exclude a possible breakdown, then you should choose a design that provides protection against overheating, power surges and dry running. Domestic pumps, the housing of which is made of cast iron, are rarely supplemented with such a set of safety elements. This is especially true for borehole pumps, the dimensions of which are very limited.
If you choose a vertical centrifugal pump, and the local network is characterized by constant power surges, then it is best to look at imported models that are equipped with the safety package described above.
Manufacturer's Reviews
If you need a centrifugal pump in the farm, the price of which varies from 2000 to 20,000 rubles, then it is especially important to pay attention to manufacturers. According to users, the most durable products are produced by the following companies: Grundfos, Karcher, Pedrollo, as well as Wilo. If you want to choose a quality product, as summer residents emphasize, it is best to pay close attention to the models on the market by Speroni SRL. It is one of the largest pumping equipment manufacturing companies.
It should be noted and such manufacturers as: Marina, as well as Speroni. They are heard by a modern consumer. No less famous are the companies: Samsung, Vipom, Belamos, Gileks. Their products have also established themselves in the market of relevant products as highly efficient and high-quality.
Conclusion
A centrifugal pump, the price of which will be lower, if we are talking about a domestic manufacturer, must have all the necessary functionality that will be required to fulfill the tasks assigned to the equipment. However, it is not always worth chasing a low cost, because it sometimes indicates not only poor quality, but also the lack of a security package. This in many cases can be extremely important for the consumer in the conditions of the relevant conditions.
