The Danish company Grundfos does not stop improving its products. Another novelty that pleasantly surprised the consumer was the compact pump station Grundfos Skala 2. This is an ideal option for operation on a suburban area. According to reviews, the pumping station manifests itself in work on the positive side.
Device and principle of operation
The main components of the equipment:
- cumulative membrane tank (hydroaccumulator) with a capacity of 0.65 liters;
- drive and control panel;
- self-priming pump;
- built-in ejector;
- pressure monitoring sensor;
- electric motor;
- check valve.
The station operates according to this principle:
- When the pump is turned on, water enters the accumulator. The pressure in the chamber of the storage tank gradually increases and when it reaches a critical value, the installation engine turns off.
- As soon as the taps of water supply to the sanitary points open in the house, water from the tank enters them. The pressure in the chamber drops, and the pump switches back into operation, replenishing the reserve of fluid in the accumulator.
With enhanced water intake, the working shaft of the unit accelerates its work. With a decrease in fluid intake, it slows down. Thus, Grundfos Scala 2 equipment constantly maintains constant pressure.
The surface installation can be successfully used to organize a cottage water supply system with 1-8 points of water intake, which is a multiple of a room of 1-3 floors and a family of 5-6 people. You can also use the Grundfos Skala 2 station to increase pressure in the mains, supply water from natural sources (wells, ponds). Additionally, the equipment is successfully used for watering garden plots.
Specifications
The Grundfos Skala 2 water station is characterized by the following technical parameters:
- water consumption - 3 900 liters per hour;
- the volume of the accumulator is 0.65 liters;
- optimal head - 46 m;
- height of absorption and water supply - 8 m;
- the maximum allowable pressure for the system is 10 bar;
- power - 550 W;
- noise level at work - 47 dB;
- the maximum allowable temperature of the transported medium is +55 degrees;
- working environment temperature - up to + 45 degrees;
- installation weight - 10 kg;
- the dimensions of the unit are 403 X 193 X 302 mm.
Manufactures equipment Serbia. The station has an insulation class equal to X4D. This allows you to mount it even in the open air.
Features of operation and maintenance
The main distinguishing feature of the station is the maximum ease of installation. The device is sold ready to install. All connections can be docked without using a special tool. Twisting is done simply by hands.
Due to the low noise level and compactness of the installation, it can be mounted even in a living room.
When connecting the equipment for the first time, it is necessary to fill it with water. It is forbidden to run the station dry. Water is poured through a special hole. Start-up is done with a single button on the control panel.
You can also use the keys to adjust the working pressure. They are located on the panel. The buttons make it easy to decrease / increase the operating pressure reading.
Additionally, the panel has indicators of errors of the station:
- problems with electricity (drops, surges);
- leaks;
- high inlet pressure;
- wedge of the working shaft;
- idling;
- inconsistencies in the temperature indicators of the environment or water (transported liquid is too hot, frost in the working room, etc.);
- simultaneous pressing of two or more buttons on the control panel;
- long time crane not closed in the house.
In all these cases, the unit is triggered to stop functioning before troubleshooting. This development allows you to protect equipment from serious damage.
Advantages and disadvantages
An automatic pumping station favorably differs from its own kind in such advantages:
- low noise during operation;
- the presence of many protection systems, which allows the master not only to protect the equipment from combustion, but also to quickly identify the reason for the station to stop;
- the possibility of cooling the working chamber with cold water transported, this ensures the reliability of the installation;
- Grundfos Skala 2 maintains a constant pressure of water in the system, which is especially good for autonomous communications;
- energy saving due to the presence in the installation of a permanent magnet motor and a frequency converter;
- the strength of the housing made of polymer composite material. The station can withstand mechanical loads and point impacts;
- the presence of a built-in ejector in the unit;
- wide area of use of the installation Grundfos Skala 2;
- maximum ease of installation and maintenance;
- low weight of equipment and its compact dimensions.
Some users minus the station consider its cost. However, the cost of purchasing the installation pays off after a year of its use.
The price of the Grundfos Skala 2 pumping station may vary slightly depending on the region of its sale. For the Moscow region, prices start at 27,000 rubles. At some points of sale, the installation may cost about 30,100 rubles.
Customer reviews
Reviews about the pumping station for a private house Grundfos Skala 2 are mostly positive. Difficulties are observed in those who have not fully studied the instructions and did not understand the control panel. But these are extremely rare cases.
Michael, 37 years old: Just last month, I bought a Scala2 installation on my 180 m2 house. I shake water from a well. Mirror of water - 4 m. Installation was easy. The inclusion was smooth and simple. The unit is quiet. Even with three taps simultaneously open (bathtub, sink in the kitchen, toilet bowl) the pressure of the water is uniform. No malfunctions were noticed. The station was set in a heated basement. Satisfied with the purchase.
Yuri, 49 years old: In the summer, I installed Skala-2 pump station on a sand well (6 meters). It delivers water almost silently. It works simply and clearly. I liked the control panel. Everything is extremely simple. Even unlucky will cope. The device pumps water with a constant pressure (since the water level in the well is normal, unchanged). In general, I have no complaints about Grundfos products.
Max, 35 years old: I bought the Grundfos Scala 2 installation for my parents in the house so that the water from the well would not be pulled by hands. The station is so smart that even a father at the age of 57 coped with it. Managed to connect and adjust the pressure buttons. The installation has been working for more than a year. Quiet, uninterrupted, with constant pressure maintenance. The main thing was to warm the pipe from the well to the house, which I did. The station itself is in a small warm dressing room. In general, I am satisfied that I spent on it. Now I’ll probably take this to myself in a new house.
