For the construction 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 with the help of pumping equipment. One of the most popular is the Caliber water supply station. The unit can easily cope not only with the supply of fluid to the system, but also with maintaining a constant pressure in the pipeline.
Device and principle of operation of stations
Equipment in the form of injection units is marked with the letters SVD, which stands for water supply station. In total, in the model range of Caliber aggregates, there are about 22 modifications. However, each of them has a similar device and principle of operation. Main elements:
- storage membrane tank (also known as a hydraulic accumulator) made of stainless steel;
- self-priming centrifugal pump, equipped with an additional induction motor;
- pressure switch.
Additionally, some plant models have 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 the faucet in the cottage, the water leaves the accumulator in the system. In this case, the pressure in the chamber drops. The pump starts up again.
These cycles are repeated in the same order, which ensures a constant pressure of water in the water supply system.
Lineup and Specifications
Caliber pumping stations have proven themselves in the installation of irrigation systems for garden plots and in the installation of an autonomous water supply. Technical characteristics differ only in final values:
- power - from 160 to 2,500 watts;
- working head - 28-70 meters;
- depth of water rise without an ejector - up to 8 meters;
- lifting depth with ejector - up to 40 meters;
- productivity - from 1.8 to 4.5 m3 / hour;
- the volume of the storage tank is 20-100 liters;
- case material - steel, cast iron, plastic.
The cost of pumping stations Caliber in the Moscow region varies in the range of 2,500-7,500 rubles. depending on the model.
In total, four varieties of water-supplying units Caliber are distinguished. In addition, each of them has its own model range.
Caliber SVD P
The most affordable stations in terms of prices. The casing of the installation is made of polymer. The main features of the equipment:
- light weight - about 10 kg;
- low noise level (it is muffled by plastic);
- resistance to corrosion.
Caliber stations marked “P” have a capacity of up to 3.6 m3 / hour; pressure - up to 46 meters; the height of the water rise is 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 it, 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 pressure. The average cost of installation in Moscow in the range of 6-7 thousand rubles.
Caliber SVD N
The case of these units is made of durable stainless steel. Metal does not allow bacteria to multiply on the walls, unlike porous cast iron. Steel stations differ in such operating parameters:
- head - up to 55 m;
- productivity - up to 7.7 m3 / hour.
To purchase a station with a storage tank of 50 or more liters, you will have to make an individual order in the store. The average cost of the stations Caliber SVD N is about 8,000 rubles.
Caliber SVD CHK
This series of stations is made in a cast-iron case and is equipped with a unit for automatic control of fluid flow. He is responsible for turning on the pump when water drops from the drive. For settings of the Cheka, 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 installation option SVD Caliber, it is important to pay attention to such 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 people will be inappropriate, costly.
- The volume of the storage tank. It is also selected depending on the needs of the family.
- Power. This parameter allows you to determine the optimal energy consumption when performing tasks.
- The height of the water. Especially if the length of the pipeline in the section is solid. To transport fluid from an Abyssinian well, it is advisable to look at a model with an ejector.
It is necessary to pay attention to the body material. If the station will stand in a warm, arranged room, you can buy a model in the polymer version. 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 fully operational. It is only necessary to connect the inlet / outlet hoses to the nozzles, fill the system with water and start the unit.
With the help of installations you can pump only clean water, without debris and impurities. Therefore, it is better to install a filter on the inlet hose. It is advisable to mount the station as close to the intake source as possible. You can arrange a special insulated caisson for the unit. Stability of the equipment is provided by the fixing legs. They prevent strong vibration of the station.
Advantages and disadvantages of pumping stations Caliber
All installations for supplying pure water have the following advantages:
- light weight and modest dimensions;
- optimal specifications for a suburban area;
- stable pressure in the system and the same pressure;
- ease of installation, control of the unit;
- the ability to keep a constant supply of water;
- system protection against 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 water flow.
The cost of the SVD Caliber installations is quite acceptable for the ordinary master.
Customer reviews
According to reviews of the Caliber pumping station, all installations fully justify the characteristics declared by the manufacturer.
Anton, 31 years old: About two years ago I bought and installed SVD-160 / 1.5 in the country. I use mainly 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 at 100%. In winter, I remove, lubricate and clean the station until the next spring-summer application. For that kind of money (something about 2.5 thousand rubles), I’m quite happy with the purchase.
Sasha, 34 years old: For six months I have been at the site of my parents station SVD-150. The pump can easily cope with the rise of water from a depth of 6 meters in 1.5-2 minutes. And this is with an optimal energy consumption of 150 watts. The noise level is extremely low. Even a child in the garden in a stroller slept in the fall without any problems. The station was equipped with a 24-liter tank. In the summer, the pump works for watering and at the same time for providing water at home (kitchen, shower, toilet, washing machine).
Miron, 39 years old: Choose between Goundfos and Caliber.It is clear that pricing is categorically different. But I did not want to overpay for the brand with almost the same technical specifications. As a result, hesitating and worried, still bought the SVD-160. And did not lose. I pump water from a sand well for home and watering. No malfunctions were detected. Under the equipment he took the platform in the basement. The station is not very noisy. On the ground floor it is almost inaudible. Just a slight buzz. With the installation and connection according to the instructions, I coped easily. Service does not cause problems. Satisfied.
