Grundfos pumping station - quick water supply for private buildings without hassle

Today, pumping stations are used everywhere, they are gradually replacing ordinary pumps from the Russian market, because they are able to automatically provide consumers with a continuous volume of water. Among the large assortment, the Grundfos pumping station stands out - it is it that is considered the best-selling among all the analogues on the domestic market of Russia.

To equip a private water supply system with such a station is a reliable and cost-effective solution. To find out all the technical parameters, advantages and minor flaws of the product, as well as get acquainted with the best models of this manufacturer, you just need to carefully read this article.

About the manufacturer

He founded the Danish company Grundfos Paul Due Jensen in the first post-war year, the main office is located in the city of Bjerringbro, Central Jutland, Denmark. The famous concern produces 16 million different pumps per year, the main groups are:

1. Circulation products UP.
2. Submersible devices SP.
3. Centrifugal Pumps CR.

In addition to the equipment listed, GRUNDFOS also produces electric motors for pumps and similar stations, as well as all components for them.

Today, the concern includes just over 80 subsidiaries and companies located in 46 countries around the world. Official representative offices have been opened in 56 countries, and some of them have production facilities: for example, in 2005, the Grundfos-Istra plant was opened near Moscow in Russia, and in 2010 the construction of the second stage of the industrial complex with its storage facilities was completed.

Instrument Features

Grundfos pumping station is a well-thought-out arrangement of all the nodes that make up a single system. A fairly robust case made of special steel reliably protects all parts from mechanical stress, so the complex can pump water from open reservoirs, from wells or wells. All parts of the station are immune to small components, for example, particles of sand or other small debris dissolved in water, so filtering of water supply disappears.

The device includes a CR class centrifugal pump and a hydraulic accumulator, but there is also a distinguishing feature from other analogues - a special ejector that works according to the Bernoulli principle. This detail allows you to increase the depth of water intake: in its absence, the station will pump water from a depth of not more than 10 meters, and if available, up to 50 m. Constant and uniform pressure is another advantage of such equipment, which is why the products are so popular in arranging water supply for private home.

The complete set is complete: a pump, a strainer, a sleeve that falls into a well or a natural reservoir, a pressure switch, a pressure gauge and fittings for connection. The automatic control system consists of a relay and a manometer, the first turns the device on and off when the pressure rises or falls, and the second monitors the internal pressure in the water supply system. The relay has two springs: a large one responds to low pressure and turns on the pump, while a small one responds to increased pressure by turning off the unit.

Advantages and disadvantages

Like any equipment, pumping stations have advantages and disadvantages, first we consider the positive qualities:

• no need for constant supervision and frequent maintenance;
• unique durability of the case and all details;
• energy efficiency;
• units with an ejector work almost silently;
• excellent pressure, high volumetric feed from a great depth;
• safe operation;
• simple assembly and disassembly;
• low financial costs when using and maintaining;
• anticorrosive coatings of parts and assemblies;
• high mobility and reliability of operation;
• increased service life.

The only drawback of the stations is the level of noise exposure when used without an ejector, but given the fact that they are located in separate caissons near a private building or cottage, it cannot be considered significant.

The model is considered one of the most reliable units for water supply of private buildings, as well as irrigation of the garden and infield. In case of overheating or lack of water, the product switches itself off. Malfunctions are only possible with improper installation or poor use.

findings

The rationality of the use of pumping stations must be calculated in each case, its power must fully correspond to the flow of water in the well or well. The product should be mounted by certified specialists, and not by “craftsmen,” who often work in a state of “partial undernutrition.”

With professional installation, equipment maintenance is minimized, only regular preventive measures and monitoring of pressure readings are needed.
