When constructing an autonomous water supply system using a well, you need a good submersible pump. With its help, it is possible to supply fluid to the line and maintain a constant pressure in the pipeline. Among the popular devices, Belamos well submersible (deep) pumps have proven themselves well.
Scope of a submersible pump
The device is widely used to organize such systems in a suburban area:
- clean water intake;
- its transportation to the highway;
- watering and irrigation of the site;
- filling storage tanks;
- small household options (car wash, etc.).
Belamos pumps are in demand among craftsmen for unpretentious installation, high performance.
Device and principle of operation
All Belamos pumps are structurally divided into the following types:
- Centrifugal. They are considered the most powerful. They have an impeller with blades. They work on the principle of centrifugal force. When turned on, the shaft starts to rotate. Due to this, the pressure drops in the chamber and water enters through the inlet pipe. The blades strongly press the liquid against the walls of the chamber, thereby pushing it up to the outlet. Work cycles are continuous. The maximum lifting height for the Belamos centrifugal unit is 120 meters.
- Screw (they are also screw). The most simple and low-performance modifications of Belamos devices. They work from a worm rotor (an analog of the Archimedes screw) located inside the bulb. The shaft is made of durable polypropylene. The engine of such devices is single-phase. The starting winding is powered through a capacitor. For shallow sand wells, these models are most suitable. These types of Belamos pumps can be installed in wells with a cross section of 80-140 mm. Using a screw pump, it is permissible to pump water with impurities in an amount of 300 g / m3.
- Vortex pumps Belamos. They work by creating a water vortex in the working chamber. They are considered the most optimal in terms of maintaining a stable pressure in the system. The impeller of the vortex apparatus is brass. The engine is single-phase. Pumps are intended only for clean water and wells with a diameter of 110 mm and more.
All Belamos devices are equipped with a ceramic-graphite mechanical seal, a non-return valve and a stainless steel body. Engine cooling is done by using environmentally friendly liquid paraffin oil.
Advantages and disadvantages
Among the main positive aspects of Belamos pumps, users distinguish:
- reasonable cost of devices;
- long term of operation;
- optimal performance;
- factory warranty for all models;
- the ability to understaff the pump with automation, which is always available;
- reasonable power consumption.
Of the minuses noted are:
- lack of soft start;
- the presence of only one protection - from overheating;
- inaccessibility of the speed adjustment option.
It is important to remember that even the most expensive pump can fail without proper maintenance and proper operation.
Overview of Belamos models
Belamos submersible aggregates are available in several major series. Each of them has its own line. In one variety, then several models of units are produced that differ in technical characteristics (productivity, pressure, power, depth of water rise).
- TF Series. Units are equipped with a floating working polymer wheel. The pressure of these devices varies in the range 42-195 m. Productivity - 2.7-5 m3 / h.The diameter of the flask is 3 and 4 inches (96-110 mm). The temperature of the pumped water is 0- + 40 degrees. For pumps of the TF series, the content of sand impurities in water is not more than 150 g / m3. The most popular models of the series are TF-60, TF-80, TF-150. The narrowest of the presented modifications is the TF3 pump. Its body has a diameter of only 75 mm. Moreover, he is able to pump water with a small amount of impurities - 180 g / m3. Of the model range, TF 3 40, TF 3 60, TF 3 110 devices are especially distinguished.
- SP Series. These submersible units have an Archimedes screw as impeller. Productivity of installations - 1.7-2.5 m3 / hour. Case diameter - 3 and 4 inches.
- TM Series. The diameter of the flask is 96 mm. Productivity - 1.9-2.5 m3 / hour. The optimum pressure is 55-100 m. Power is 900-1300 watts.
- TS Series. These are the most productive devices for the well. They are capable of delivering from 11 to 18 m3 / hour. Head - 100-260 m. Three-phase power supply requires consumption of 7.5 kW / h. Impeller blades are made of stainless steel.
Regardless of the type of series selected, you should pay attention to the labeling of the device. It shows the nominal head (first digits) and pump capacity in m3 (second numerical value).
How to choose a pump
To buy the optimal model of the deep well, it is important to know the following parameters of the well:
- Performance. When buying a pump, it should not be lower than indicated in the technical specifications for the device. Otherwise, the device will quickly drain the source, which leads to the risk of its idling.
- The diameter of the well shaft. It is important as the pump sleeve may not enter the barrel. It is desirable that the cross-section of the flask be at least 5-10 mm smaller than the diameter of the source. Then it is possible to put on it a dense rubber ring that protects the casing from the mechanical effects of the steel casing.
- Depth of water mirror and well shaft. It is necessary in order to calculate the necessary pressure for the purchased equipment. It is important to note that every 10 m of the horizontal section of the pipeline is equal to 1 m of pressure. That, in turn, is calculated from the point of the intended immersion to the farthest plumbing fixture in the house. It is necessary to add all the vertical and horizontal sections of the highway in meters.
- Power. Here, each of the masters selects a device according to its capabilities. Someone can afford a more productive unit. And someone can afford modest models.
Be sure to consider the performance of the device per hour. To do this, you need to summarize the amount of water consumed per family over a period of time. And on all sanitary points of the house.
Installation and connection
The connection and installation of the Belamos pump is almost no different from the installation of other downhole devices. The work is carried out in several stages:
- Installation of a coarse filter on the inlet pipe (if desired).
- A hose is attached to the outlet using fittings and is equipped with a check valve. Approximately 1 m above the pump housing.
- All connections are sealed.
- A safety cable is attached to the eye on the device case. Preferably nylon is durable, not steel. The latter may rust and break.
- In parallel with the cable on the ground, they lay the required footage of the electric cable and hose for lifting water.
- So that they do not hang randomly in the well, it is advisable to fasten all three elements with ordinary construction clamps with a step of 1 m. The fastening pins should be cut as much as possible. It is important to ensure that there is no strong cable tension, cable or excessive sagging.
- Now you can lower the pump to a predetermined depth. As soon as it reaches the desired mark, the safety cable is fixed to the frame in the head of the well.
It remains to connect the device to the network. If the water is supplied without interruption, then everything is done correctly.
Cost
Prices for submersible pumps for the Belamos well vary depending on the series and technical characteristics of the unit. On average, in Moscow for pumps you can give such sums:
- from 5000 rub. and higher for SP series models;
- from 8000 rub.for devices of the TF series;
- from 6000 rub. for pumps from the TM line;
- from 13000 rub. for centrifugal devices of the TS series.
Prices may vary slightly depending on the region and point of sale.
