How to choose a pumping station for a private house
More and more people decide to move to live outside the city, at least for the summer season. And accordingly, they immediately face a vital task: how to provide the house with water.
Pumping stations are just coming into use, so the questions are not at all surprising:
- what is a pumping station?
- positive and negative sides: is the game worth the candle?
In this article, we will answer these and other questions in detail.
A pumping station is needed to provide clean water, in cases where there is no centralized water supply system. That is, this device helps to extract water from a well, reservoir, well.
The pumping station consists of two systems: one is responsible for the supply of water, the other for drainage.
That allows using them not only to filter, but also to supply a private house with purified water. The basis of the device is a pump. But in order for the work to be brought to automatism, in addition to it, there are pressure sensors, a water tank, a hose, an adapter fitting, a hydraulic accumulator, and a pressure gauge. Depending on the manufacturer and the tasks set, the equipment may be different. For example, for domestic use, it will be enough to use a station with two pumps, but for industry this is not enough.
Principle of operation
The pumping station pumps water from the well into the tank. The pump filling the tank with water stops automatically when the extreme high pressure is reached. If water is used in small quantities, then without turning on the pump, it comes from the tank. And also the pumping station automatically starts its work as soon as the extreme lower pressure in the tank is reached.
The pumping system has its advantages:
- The most obvious of them is the automatism of work.
- You can combine the provision of water at home and, for example, a garden or farm.
- If there is a power outage, the water collapse will not occur, as the pumping station is "stocked" with water.
- In comparison with other systems - low cost and compactness of the device.
So are the cons:
- Noisy work. There is only one way out of this: installation away from home. Not everyone has such an opportunity.
- Small suction depth: most stations have a limit of up to eight meters.
Kinds
First: pumping stations for a country house can be divided according to the type of their placement:
- submersible: placed in water. Borehole or well.
- Surface: vortex, multi-stage, with a remote ejector.
What characteristics to look for?
- pump power.
- suction depth.
- Performance.
- Water intake height.
- Installation energy consumption.
- Battery: volume.
For a constant supply of water to a house on one floor, a family of two to four people, a hydraulic accumulator is suitable fifteen liters capacity. The pump power, in this case, should be no more than 1.2 kW / h.
For a multi-storey building, a more powerful pump is accordingly needed. Also, the choice of the volume of the accumulator depends on the number of residents, whether there is a farm, a garden, and more.
If the water is located near the surface, it is worth choosing surface pumps operating at a depth of eight meters. In the case when the water "is" deep, a submersible pump with a built-in ejector is more suitable. A pump with an external ejector is less noisy, but it cannot be fixed in wells with a clay bottom, as they quickly become dirty.
It is easy to install a surface pumping station yourself, it is more correct to entrust submersible installation to a specialist.
Price
Pumping stations are very different in price. The reasons lie both in the brand and in the characteristics and materials. A less noisy pumping station will be more expensive. On average, the price of a pumping station varies from ten to twenty.
German devices are considered good home stations: Karcher, Gardena, and Grundfos. They are distinguished by high productivity, safety of work. But they are not cheap either. True, the Germans are also the cheapest. Company pumping stations Metabo can be purchased in the region of six thousand.
Buyers often choose Italian companies: Pedrollo, Marina, Ergus.
Among domestic manufacturers, it is worth highlighting the company "Dzhileks". They are ideally matched in the price-quality category.
Let's take a closer look at a few brands.
Grundfos stations
Advantages of the pumping station of this company:
- precise water supply at the right pressure.
- The main parts are made of high quality metals. Therefore, the device is not subject to corrosion.
- In case of any failures, the automation will turn off the pumping station. After solving the problem, it will start the working mode.
The cost of the pumping station of this company is from 16 thousand rubles.
Pump station Grundfos MQ 3-45. The cost is 24200 rubles.
WILO
The company sells pumping stations for both industry and the private sector.
Their main advantage is the ability to supply water to a great height. The set of such stations includes five or more pumps.
The cost of devices of this company is average - from 10 thousand rubles.
Gilex Jumbo
As we said earlier, this is a Russian product. In comparison with foreign analogues, it is simple. The price is not high - you can find options from 4,000 thousand rubles, while the pumping stations of this company are reliable.
Gilex Jumbo 70/50 P-24.
Caliber
Russian production. The buyer here may be interested not only in the price - from 3,000 thousand for a pumping station. But the volume of the tank is up to 50 liters. At the same time filling 120 liters per minute.
Caliber svd 160
Marina
Production: Italy, China. Positive sides:
- water rise more than 20 meters.
- Reliability, long service life.
- Value for money. You can find models from 8 thousand rubles.
Pumping equipment is presented in a good choice, this has its positive and negative sides. It is not easy to figure out which pumping station is suitable in a particular case. In addition to reliability in use, it must "recoup" the costs of its acquisition, installation and operation.
Causes of breakdowns
Even if you choose the highest quality and most reliable pumping device, over time it may fail. Most of the failures are eliminated without calling the wizard.
- The pump makes noise, but the water does not rise. This is a common problem for stations operating in manual mode. Causes of failure: contamination of parts of the pumping device: filter, check valve. It may also be a lack of water between the well and the pumping station.
Simply clean the filter and pour water into the pipe through the pump opening. In the second case, the pump must be lowered lower.
- Periodically turns on and off on its own. Causes: there is no necessary pressure in the hydraulic tank, the diaphragm that separates air and water is damaged, the pressure switch does not work. The tank should be checked for cracks. Cold welding will eliminate cracks. If the relay or diaphragm is broken, then they must be changed.
- The pump does not turn off. Reason: pressure switch. Remove relay and clean from salt.
- The pump makes noise but does not lift water. Reasons: in the mains - low voltage. The pumping station did not work for a long time, for example, such problems occur after winter. Capacitor failure.
What to watch?
Most reviews on this topic are promotional. Firms offer and analyze only their pumping stations. This Video "selection of a pumping station" also from a construction company, but men in a three-minute video tell the main things about pumping stations: what they consist of, and what criteria should be used to choose a household pumping station for a house. The information is more practical. This video is suitable for people who are faced with the purchase of a pumping station for the first time.
Everything about pumps. How to choose a pump and what pumps are . This video is also short: 4 minutes. It tells more about the types of pumping stations. In addition to conventional pumping stations, they also offer drainage ones. The information in the video is more detailed, but there is little practical information.
In addition to numerous reviews, mostly of an advertising nature, there are many training videos on the network on how to repair the pumping station yourself.
