Centrifugal pumps for irrigation: advice on choice and manufacturer feedback

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 your choice. Inside the case is a shaft provided with blades. During rotation, a depression is created in the central part of the rotor due to the centrifugal force, which throws water onto the edges of the blades. The new liquid enters the dilution zone, after which the cycle is repeated.

The technical side should not be interested too deeply, as this will not help in solving such issues as operation and installation. It is important to get acquainted with the cost and feedback, which will allow you to understand which models are the most common and popular.

Customer Reviews

If you are interested in centrifugal pumps for irrigation, you should familiarize yourself with the feedback of customers who have been using this equipment for more than one year. As noted by summer residents, 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 near the well, and only the hose should be immersed in the water. Users note that the maximum maximum depth with which water intake can be carried out is 10 meters. This indicator is enough for watering the territory in the country. Consumers like it that the device has a small weight and size, it facilitates the use of equipment.

Experts advise installing the device on a flat platform, checking in advance whether there are foreign impurities and impurities in the liquid. This is due to the fact that the device is designed exclusively for pure liquid. Some lovers of country holidays say that it is not convenient to hide the device for pumping water from rain. For the operation of surface pumps it is necessary to use a special reinforced hose. It is necessary to exclude the use of rubber, as it is not suitable because of rarefaction. The latter is created during operation, when a soft hose can stop the flow of water at the moment of flattening.

Advice of a specialist

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 it can be smoothened by mounting the device away from home or in a special room. Before you turn on the surface centrifugal pump, it must be filled with water.

Recommendations for selection

If you decide to purchase the described device, which will be used for watering the garden or any other territory, it is initially recommended to deal with some characteristics. This will make it clear whether the equipment is suitable for specific conditions.

The decision on which design to choose (surface or submerged) will depend solely on the depth of the source. If it is a question of deep wells, it is best to choose a submersible model, which will need to be lowered and fixed with the utmost care. If we are talking about a depth that reaches 10 meters, then we can use a superficial centrifugal option.

Selecting the pump by pressure

If you are interested in centrifugal pumps for irrigation, then you need to pay special attention to the head. This indicator is also called the capacity of the unit. He makes it clear to what distance and from what depth the device will be able to transport the liquid. Quite often, consumers do not calculate with pressure, so in the process of 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 the water intake will be made.

If you decide to select a surface centrifugal pump for irrigation, then you need to take into account that for 1 meter of vertical lifting you need the same amount of energy as 10 meters of horizontal pumping. For example, if the depth of the well is 4 meters, then the pump head should be equal to 7 meters. This indicates that the device will be able to lift liquid from a 4-meter depth and pump it for a distance of 30 meters or less. After you can determine at what distance from the well are beds, 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, then it is necessary to exclude the operation of the pump at the maximum depth. If the head indicates a pressure equal to 8 meters, this does not mean that the equipment is suitable for continuous pumping at such a depth. This indicator is the maximum permissible. Experts recommend using equipment whose head is selected with a margin. Otherwise, the unit may not be able to cope with the tasks.

Selecting a pump by material

If you need a centrifugal pump to give, it is important to decide which material will be the basis of the design. The worst solution is plastic, then comes cast iron, and in the first place is stainless steel. If there are abnormal situations, the plastic housing or individual parts of this material may not withstand overloads. The plastic impeller is often damaged due to ingress of foreign impurities. If we are talking about cast-iron elements, then they have a more impressive weight, and are prone to corrosive processes.

Household centrifugal pumps for irrigation are presented in modern stores in a wide range. If you need similar equipment on the farm, it is best to choose a structure, the body of which is made of stainless steel. It is resistant to corrosion, reliability and ease. However, cast-iron housings are cheaper, which is why they are the most popular in the domestic market among consumers.

Selecting a safe pump

The centrifugal pump must necessarily be safe in terms of protection against voltage surges. If you wish to exclude a possible breakdown, it is worth choosing a design that provides protection against overheating, voltage surges and dry running. Domestic pumps, whose body is made of cast iron, are rarely supplemented with such a set of safety elements. In particular, this is relevant for downhole pumps, the dimensions of which are very limited.

If you select a vertical centrifugal pump and the local network is characterized by constant voltage surges, it is best to look at the imported production models that are equipped with the above safety package.

Reviews of manufacturers

If you need a centrifugal pump on the farm, the price of which varies from 2000 to 20,000 rubles, it is especially important to pay attention to the producers. As users note, the most durable products are produced by the following companies: Grundfos, Karcher, Pedrollo, and also Wilo. If you want to choose a quality product, as the summer residents emphasize, it is best to pay close attention to the models presented on the market by Speroni SRL It is one of the largest companies in the manufacture of pumping equipment.

It should be noted and such manufacturers as: Marina, as well as Speroni. They are heard by the modern consumer. No less famous are the companies: Samsung, Vipom, "Belamos", "Gileks". Their products also proved themselves in the market of the corresponding goods, as highly effective and high-quality.

Conclusion

Centrifugal pump, the price of which will be lower, if it is a domestic manufacturer, must necessarily have all the necessary functionality that will be required to perform the tasks assigned to the equipment. However, it is not always worth pursuing low cost, because sometimes it indicates not only poor quality, but also the absence of a security package. This in many cases can be extremely important for the consumer in the conditions of the appropriate conditions.
