Every year, suburban construction is gaining momentum. With it, you can solve the housing problem, providing a beautiful view from the window. However, as a rule, there are big problems with the infrastructure in cottage villages. One of the most important tasks is water supply. Of course, the well is able to partially solve this issue, but the townspeople who are used to comfort are not always ready to put up with such a decision.
Solution
At each site today, an autonomous functional water supply system is installed. In some cases, it is based on a well, while in others it’s a well. In the first embodiment, you can use a surface water pump. This type of pump will be able to provide water to the whole family. Such equipment is easy to maintain and also affordable.
general description
If we are talking about a surface pump, then it does not involve immersion in water, only a water intake hose is lowered there. The maximum depth that this unit will be able to handle is nine meters. Therefore, such a pump is not suitable for working in tandem with a well, while just right for a spring or a shallow well. If you choose water pumps for a well, a surface pump will not work, keep this in mind.
The equipment copes well with pumping water from the basement, with its help it will be possible to water the personal plot. Surface pumps are excellent for wells that are located on quicksand.
Varieties
So, you have decided to choose a water pump. A surface pump of this type can be centrifugal, vortex or have an external ejector. Swirling its variety is the most compact, as well as the most affordable. The equipment will be able to create a pressure that is a maximum of seven times greater than that of a centrifugal device. However, the efficiency in this case is 45%.
If you choose surface water pumps for cottages, then you should not use vortex pumps to pump liquid, which may contain a significant amount of various impurities and sand. This is due to the fact that the wheels in this case quickly become unusable. Such a device is able to raise water with the help of a wheel and a rotating shaft, on the first of which there are peculiar spatulas. The latter are designed to give the liquid energy that comes from the working axis.
Should I choose centrifugal equipment and a device with an external ejector?
Today, in a country house, a water pump is very common. A centrifugal type surface pump should not be selected if it is intended to pump heavily contaminated water. However, such an aggregate perfectly copes with a liquid that contains plugs and bubbles.
Such equipment is more expensive than a vortex, as it has a large number of steps. This design functions due to the presence of wheels that pump pressure. They are driven by a working shaft, which is supported by bearing systems. If you decide to prefer a pump that is equipped with an external ejector, then it is worth considering that this equipment is practically not used today. He was replaced by submersible pumps, whose performance is much higher.
Positive reviews
A water pump is quite popular today among summer residents. This type of surface pump has many advantages. According to customers, they like the moment that the equipment is compact, as well as low weight. Among other things, consumers indicate affordability and ease of installation.
The unit is also easy to maintain and operate. Even a master who does not have certain skills, knowledge and experience can install a surface pump. Surface water pumps for summer cottages, as users emphasize, are distinguished by the possibility of functioning with a water layer whose thickness is eighty centimeters. Submersible pumps in such conditions are not able to work.
Consumers especially note another positive feature, which is expressed in air-cooled cooling. For submersible pumps, this function is provided by water.
Reliability Reviews
Such devices have an impressive efficiency, and when connected, there is no need to supply electricity to the water intake. Experts advise to choose surface pumps also for the reason that they differ in durability and reliability. Even with air congestion in the system, units of this type are able to guarantee stable operation.
Negative reviews
When choosing water pumps for a well, you may not even consider a surface one. However, for domestic needs, it will fit perfectly.
Before going to the store, you must also familiarize yourself with negative reviews. Among the negative aspects, one can single out sensitivity to the presence of all kinds of contaminants, impurities, including sand.
It is better for consumers to refuse to purchase such equipment when the depth with which to collect water exceeds 9 meters. When using an ejector, the performance and reliability of the system are significantly reduced.
Fans of suburban recreation quite often make a choice in favor of other varieties of pumping systems, due to the noise that accompanies the operation of a surface-type device.
Surface water pumps, the price of which can start from 15,000 rubles, should be installed in a separate room. Another negative feature is the need to fill the suction line with water.
Selection tips
Surface water pumps, the price of which will depend on the quality characteristics, should be selected depending on the goals that you pursue. If you plan to use the equipment for watering a personal plot, it is important to pay attention to several basic parameters. Among them, we can single out performance.
Thus, one cubic meter per hour will be sufficient for watering the garden. The future owner of the device must also take into account the suction depth at which the equipment is supposed to be used. Given that the maximum water intake depth is 9 meters, you need to remember the horizontal to vertical ratio, which is 4 to 1.
If you will use equipment that is tasked with water intake from a two-meter depth, then the pump should be removed from the well by 8 meters. If you increase the suction depth to 4 meters, you need to increase the lumen of the pipe to an indicator equal to 1/4 inch. This statement is also true with a significant length of the supply line, which can be more than 12 meters.
If you are considering surface water pumps for summer cottages, the prices of which are considered acceptable today, it is important to pay special attention to pressure. When choosing this option, you need to focus on the most distant point at which consumption will be made.
How to choose a pump for a country house
Surface water pumps for summer cottages, prices for which can reach 25-30 thousand rubles, are often selected for country houses. In this case, one should focus on the volume of fluid consumed, the necessary pressure in the system, as well as the number of consumption points.
In order to facilitate the calculation, you can use the values presented below. If 4 people will temporarily live in the house, then the consumption per hour is 3 cubic meters. For a two-family house, 5 cubic meters per hour will be needed. If the house has 4 families, then it will take 6 cubic meters per hour. For a personal plot you need to count on 1 cubic meter per hour.
If you decide to purchase an electric surface water pump, it is important to consider that you may have to use it in dry times. At the same time, water consumption increases significantly. Watering on hot days takes up 55% more fluid than usual.
The choice of the pump on the accumulator
If you choose a water pump for surface irrigation, it is important to consider the parameters of the accumulator. With a set value of 3.5 atmospheres, the most impressive head in the system should be greater than the total vertical and horizontal pressure compared to the supply line. At the same time, the distance to the water should be +50 meters. The step, the length of which is ten meters vertically or one hundred horizontally, must be equated to a pressure equal to one atmosphere.
Conclusion
Before you purchase a device, it is important to learn how to install. The surface water pump involves installation work using the outlet and supply hoses, a hydraulic accumulator, a connecting fitting, a check valve, a pressure gauge, and a pressure switch. The life of the equipment will depend on how correctly you make the connection. The unit must be installed on a flat, solid surface, on the basis of which the device will need to be well fixed. Among the most popular brands are Karcher, Eco, Patriot, IBO, Diold and Aquareobot.
