For the device of an autonomous water supply system in a suburban area, it is more convenient to make your own sources - wells or wells. It is better to supply water from them to the house using pumping equipment. One of the most popular is the Kalibr water supply station. The unit easily copes not only with the supply of liquid to the system, but also with maintaining a constant pressure in the pipeline.
The device and principle of operation of the stations
Equipment in the form of injection units is marked with the letters SVD, which stands for water supply station. In total, the model range of Caliber units includes about 22 modifications. However, each of them has a similar structure and principle of operation. Main elements:
- storage membrane tank (also known as a hydraulic accumulator) made of stainless steel;
- self-priming centrifugal pump, additionally equipped with an asynchronous motor;
- pressure switch.
Additionally, in some models of installations there is an ejector designed to increase the suction force. Thanks to this, the equipment can be used to supply water from the Abyssinian well.
The principle of operation of the installations:
- The unit is mounted on the surface, filled with water.
- Lower the suction hose into the source and turn on the equipment.
- The tank is completely filled with water until the pressure rises to the set limit value. As soon as this happens, the pump turns off.
- When you open a tap in a cottage, water flows from the accumulator into the system. At the same time, the pressure in the chamber drops. The pump starts up again.
These cycles are repeated in an unchanged order, which ensures a constant water pressure in the water supply system.
Model range and technical characteristics
Pumping stations Kalibr have proven themselves well when arranging irrigation systems for garden plots and when installing an autonomous water supply system. Technical characteristics differ only in final values:
- power - from 160 to 2,500 W;
- working head - 28-70 meters;
- water rise depth without an ejector - up to 8 meters;
- lifting depth with an ejector - up to 40 meters;
- productivity - from 1.8 to 4.5 m3 / hour;
- storage tank volume - 20-100 liters;
- body material - steel, cast iron, plastic.
The cost of pumping stations Caliber in the Moscow region varies between 2,500-7,500 rubles. depending on the model.
In total, there are four types of water supply installations Caliber. Moreover, each of them has its own lineup.
Caliber SVD P
The most affordable stations in terms of prices. The unit body is made of polymer. The main features of the equipment:
- small weight - about 10 kg;
- low noise level (it is muffled by plastic);
- corrosion resistance.
Caliber stations marked "P" have a capacity of up to 3.6 m3 / hour; head - up to 46 meters; the height of the water rise - up to 8 m. The temperature of the pumped medium for such an installation is up to +40 degrees.
Caliber SVD ECHK
This is the most powerful pumping equipment of all SVD Caliber. The units are equipped with a remote ejector. Thanks to him, the units are able to supply water from great depths - up to 40-60 m. However, the ejector somewhat reduces the productivity of ECHK stations to 1.7-1.75 m3 / h, while improving the pressure. The average cost of an installation in Moscow is within 6-7 thousand rubles.
Caliber SVD N
The body of these units is made of robust stainless steel. Metal prevents bacteria from growing on the walls, unlike porous cast iron.Steel stations are distinguished by the following operating parameters:
- head - up to 55 m;
- productivity - up to 7.7 m3 / hour.
To buy a station with a storage tank of 50 liters or more, you will have to make an individual order in the store. The average cost of Kalibr SVD N stations is about 8,000 rubles.
Caliber SVD CHK
This series of stations is made in a cast-iron casing and equipped with an auto-control unit for fluid flow. He is responsible for turning on the pump when the water decreases from the reservoir. For CHK installations, the following parameters are characteristic:
- productivity - 30-48 l / min;
- water rise height - up to 8 meters;
- head - 20-60 m.
More often, such stations are used on landscape irrigation systems or car washes.
How to choose a station
To buy the best option for installing SVD Caliber, it is important to pay attention to the following points:
- Performance. It is calculated by the number of residents in the house. If the station cannot cope with the supply of the required volume of water, it will be useless. As well as the excessive performance of the unit for a family of two will be inappropriate, costly.
- Storage tank volume. Also selected depending on the needs of the family.
- Power. This parameter allows you to determine the optimal energy consumption when performing the assigned tasks.
- Height of water rise. Especially if the length of the pipeline along the section is solid. For transporting fluid from an Abyssinian well, it is advisable to look at a model with an ejector.
You need to pay attention to the material of the case. If the station will be located in a warm, well-arranged room, you can buy a polymer model. For more severe operating conditions, it is advisable to take steel or cast iron. However, the latter is prone to corrosion over time.
Features of operation and maintenance
Caliber pumping stations are sold ready-to-use. You just need to connect the inlet / outlet hoses to the nozzles, fill the system with water and start the unit.
With the help of installations, only clean water can be pumped, without debris and impurities. Therefore, it is best to install a filter on the inlet hose. It is desirable to mount the station as close as possible to the water intake source. You can arrange a special insulated caisson under the unit. The stability of the equipment is ensured by the fixing legs. They also prevent strong vibration of the station.
Advantages and disadvantages of pumping stations Caliber
All installations for supplying clean water have the following advantages:
- light weight and modest dimensions;
- optimal technical characteristics for a suburban area;
- stable head in the system and the same pressure;
- ease of installation, unit control;
- the ability to keep a constant supply of water;
- protection of the system from water hammer due to the presence of a membrane tank;
- full automation of the system;
- the presence of protection against dry running, leaks, overheating, reverse flow of water.
The cost of SVD Caliber installations is quite acceptable for an ordinary master.
Customer Reviews
According to reviews of the Kalibr pumping station, all installations fully justify the characteristics declared by the manufacturer.
Anton, 31 years old: About two years ago I bought and installed an SVD-160 / 1.5 at my dacha. I mainly use it for watering. I pump water from a well from a depth of 5.5 meters. The installation works, it happens, for 3-4 hours continuously and everything is in order with it. Of course, I'm not talking about work all year round, but it is during the watering season that the unit works 100%. In winter, I remove the station, lubricate it and clean it up until the next spring-summer application. For that kind of money (something about 2.5 thousand rubles) I am quite happy with the purchase.
Sasha, 34 years old: I have an SVD-150 station on my parents' site for six months. The pump easily copes with the rise of water from a depth of 6 meters in 1.5-2 minutes. And this is at an optimal power consumption of 150 watts. The noise level is extremely low. Even a child in the garden in a stroller slept without problems in the fall. The station was equipped with a 24-liter tank. In summer, the pump works for watering and at the same time providing water for the house (kitchen, shower, toilet, washing machine).
Miron, 39 years old: I chose between Goundfos and Caliber. It is clear that the pricing policy is categorically different. But I didn't want to overpay for the brand with almost the same technical characteristics. As a result, hesitating and worrying, he nevertheless bought an SVD-160. And he made the right decision. I pump water from a sand well for home and for irrigation. No malfunctions were found. I set aside a platform in the basement for the equipment. The station does not make much noise. On the first floor, you can hardly hear it. Only a slight hum. I easily coped with the installation and connection according to the instructions. Maintenance is not a problem. Satisfied.
