What is the pumping station Grundfos Skala 2

The Danish company Grundfos never ceases to improve its products. Another novelty that pleasantly surprised the consumer was the compact pumping station Grundfos Skala 2. This is an ideal option for operation on a suburban area. According to reviews, the pumping station manifests itself in a positive way.

Device and principle of operation

The main components of the equipment:

• storage membrane tank (accumulator) with a capacity of 0.65 liters;
• drive and control panel;
• self-priming pump;
• built-in ejector;
• pressure control sensor;
• electric motor;
• check valve.

The station works according to the following principle:

• When the pump is turned on, water enters the accumulator. The pressure in the storage tank chamber gradually increases and when its critical value is reached, the engine of the installation turns off.
• As soon as the water supply taps to the plumbing points are opened in the house, water from the tank enters them. The pressure in the chamber drops, and the pump turns on again, replenishing the fluid reserve in the accumulator.

With a reinforced water intake, the working shaft of the unit accelerates its work. With a decrease in fluid intake, it slows down. In this way, the Grundfos Scala 2 equipment maintains a constant head at all times.

A surface installation can be successfully used to organize a water supply system for a cottage 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 station Grundfos Skala 2 to increase the pressure in the mains, supply water from natural sources (well, pond). Additionally, the equipment is successfully used for watering garden plots.

Specifications

For the water station Grundfos Skala 2, the following technical parameters are characteristic:

• water consumption - 3,900 liters per hour;
• accumulator volume - 0.65 liters;
• optimal head - 46 m;
• suction and water supply height - 8 m;
• the maximum allowable pressure for the system is 10 bar;
• power - 550 W;
• noise level in operation - 47 dB;
• the maximum allowable temperature of the transported medium is +55 degrees;
• operating temperature of the environment - up to + 45 degrees;
• installation weight - 10 kg;
• unit dimensions - 403 X 193 X 302 mm.

Serbia manufactures equipment. The station has an insulation class equal to X4D. This allows it to be mounted even outdoors.

Features of operation and maintenance

The main distinguishing feature of the station is the maximum ease of installation. The device is sold ready for installation. All connections can be connected without the use of a special tool. Twisting is done simply by hand.

Due to the low noise level and compactness of the unit, it can be installed even in a residential area.

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 is done with one 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 contains indicators of station operation errors:

• problems with electricity (drops, surges);
• leaks;
• high inlet pressure;
• working shaft wedge;
• idling;
• inconsistencies in the temperature indicators of the environment or water (too hot transported liquid, frost in the working room, etc.);
• simultaneous pressing of two or more buttons on the control panel;
• a tap not closed for a long time in the house.

In all these cases, the unit is triggered to stop functioning until the malfunctions are eliminated. This development allows you to protect the equipment from serious damage.

Advantages and disadvantages

An automatic pumping station compares favorably with similar ones with such advantages:

• low noise level during operation;
• the presence of many protection systems, which allows the foreman not only to protect the equipment from combustion, but also to quickly identify the reason for the station shutdown;
• the possibility of cooling the working chamber with transported cold water, this ensures the reliability of the installation;
• Grundfos Skala 2 maintains a constant water pressure in the system, which is especially good for autonomous communications;
• energy savings due to the presence of a permanent magnet motor and a frequency converter in the installation;
• the strength of the case, made of polymer composite material. The station can withstand mechanical loads and point shocks;
• the unit has a built-in ejector;
• wide area of ​​application of the installation Grundfos Skala 2;
• maximum ease of installation and maintenance;
• low weight of the equipment and its compact dimensions.

Some users consider the station's disadvantage its cost. However, the cost of purchasing the installation pays off within a year of its use.

The price of the pumping station Grundfos Skala 2 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, installation can 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 have not figured out the control panel. But these are extremely rare cases.

Mikhail, 37 years old: Just last month I bought myself a 180 m2 Scala2 installation. I pump water from the well. Water mirror - 4 m. Installation was easy. Turning on was smooth and easy. The unit works quietly. Even with three taps open at the same time (bath, kitchen sink, toilet), the water pressure is uniform. No malfunctions were noticed. I put the station in a heated basement floor. Satisfied with the purchase.

Yuri, 49 years old: Pumping station Skala-2 installed in the summer on a well on the sand (6 meters). It delivers water almost silently. It works in a simple and straightforward manner. Liked the control panel. Everything is extremely simple. Even a clumsy man can cope. The device pumps water with a constant pressure (fortunately, the water level in the well is normal, unchanged). In general, I have no complaints about Grundfos products.

Max, 35 years old: I bought a Grundfos Scala 2 installation for my parents in the house, so that water from the well would not be dragged by hands. The station is so smart that even a father, at the age of 57, mastered it. I managed to connect and adjust the pressure with the buttons myself. The installation has been in operation for over a year. Quiet, uninterrupted, with constant pressure. The main thing was that the pipe from the well to the house was well insulated, which I did. The station itself is in a small warm dressing room. In general, I'm happy that I spent on it. Now, I’ll probably take one to my new home.
