Type of review

When replacing dead pumps, the warranty each time started counting from zero (the pump is new!). So with this in mind, I got myself almost perpetuum mobile - 9 years warranty :)! With its pros: - Of course, noise (more precisely, its absence) - Compactness - Simplicity (works out of the box) - 5-year (!) warranty - Customer Service Cons: Early models (before 2022) had a problem - one and a half to two years - and died. Exchanged two pumps under warranty. Scala releases after 2022 are said to…

I bought a Scala 2 and We forgot what noise is, We forgot that the pressure increases and then drops, that the pump turns on and builds up pressure and then turns off - it's all in the past. Now there are no questions about water, pressure, water pressure at all. I bought a second rock for production for electroplating. Silence, pressure, pressure - all at the highest level. Employees sit next to him and do not realize that this plastic box is working at this time. Recently, the pump went into…

Pros
  • The best pump and Grundfos - a worthy brand manufacturer
Cons
  • Previously, there was a station at home. Model P10510 - stainless steel - makes noise when it works. But damn 15 years has been noisy. Drove to production - 4 floors supply water. Even now, when I type this text, it still works.

Temporary rescue, pumps normally for 1 tap, from the central water supply. 2 taps is good, 3 taps is already so-so. But I have 1 filter. Although pipes uponor 25! In general, if there are 2 bathrooms (flushed the toilet, wash your hands, washes the washing machine, pours in the bathroom, and the second bathroom also has 4 children, the wife cooks in the kitchen and the dishwasher works) and the kitchen, then there is no point in this pump! Of course, water does not flow around the clock, but…

Pros
  • Pumps water, just connect.
Cons
  • Noisy like a microwave! Pumps on 2 cranes !

Good kid. It stands on the well, from the first water it pumped water immediately, I didn’t have to bother with filling, pumping, there is protection against dry running, some other lotions, we haven’t figured it out yet. For us, the main thing is that it pumps without interruption, the pressure is stable and at the same time it takes up very little space, it does not rumble like a tractor. Happy with their choice.

Pros
  • Good quality, compact, not noisy, there is protection against dry running.
Cons
  • not revealed yet

Excellent product, the best quality.

It works well on the Abyssinian well 7m at 2 atm. The pressure does not jump, it is very quiet, it can be installed in the house, it is easy to install, you can set up automation and forget about it. There is an auto-shutoff that can be set to run for more than 30 minutes. Most importantly, a 5 year warranty! Departure of the service literally the next day. Average price 24-25t.

Pros
  • Quiet, reliable, super smart.
Cons
  • did not notice.

Matches the description completely, very satisfied.

Shows a leak error. Houses installed "reverse osmosis" Although this is not even a minus! Initially, the pump was in the boiler room and from the barrel it built up pressure from 0 to 3 bar for the whole house, it made a decent noise. After he removed it to the underground room in the 1.5 bar system, the pump raises to 3 bar, the noise disappeared. Quieter than a refrigerator. Convenient and clear control.

Pros
  • Super pump!
Cons
  • No

Product is disappointing, not what it promises.

This is my first NS, all the previous ones were ordinary pumps with a flow sensor, even without HA. I use it to increase the pressure in the city, i. E. minimum pressure (2-3 bar) and the availability of water is guaranteed. Immediately alarmed two points. First: the product periodically turns off for 3 seconds (the first time after 20-25 seconds after the start and then every few minutes), then it turns on again as if nothing had happened, while the indicators show the normal operation mode…

Pros
  • 1) Relatively quiet, although at full speed the noise is still noticeable. 2) Cool protection, you don't have to worry that a decorative small animal will find a loophole or accidentally stick its tail into any hole. 3) The pressure is what you need. 4) Compact and lightweight! 5) All iron and plastic, both inside and outside, are perfectly fitted to each other, everything is in its place, there is almost nothing to "improve" except .
Cons
  • 1) Stupid, very stupid firmware running the whole thing. Thanks to this, all the qualities and advantages that distinguish this product from others are reduced to nothing, become ordinary or even worse than those of competitors. 2) The alleged reason for the flaw 1 (see comments): the comrades spent a lot of time and money on the development of hardware, and then 1 day (literally!) To write the microprogram. Meaning - the NS has a Renesas RL78 series control microcontroller, and so Renesas has its own feature for its microcontrollers - a convenient visual tool for "programming", Applilet is called - you drag the blocks, connect them, and voila - the "program" is ready. Here in Grundfos, some smart guy decided to save money - he put a student in or even sat down himself, not having special skills and understanding in this matter, he took as a basis some appnote from the same Renesas, without thinking twice, slightly edited it. Everything is the result. And THIS works in your NS, exactly THIS is the "feature" of this NS, when it does not work as it should with a well or city water supply, in a word, it works through one place . 3) More than half a year of use - the flight is normal (almost resigned to stupidity). Then they switched it to the "Stop" mode for several days, then back to normal mode and . There was a loud extraneous sound, like the rattling of a diesel engine, and it began to leak a little from the hole from the bottom in the middle, although it did not become worse functionally. Dismantled, pulled out a rosette with a shaft - inside everything is wet and covered with a touch of rust, incl. and bearings. I took out the lubricant as indicated in the Service instructions, washed it, lubricated it, dried it, all the rubber bands were like new. The result - it leaks and rumbles all the same, I no longer need such feces. I tried to carefully add rubber bands to the stuffing box, the leak decreased, but it still rumbles. It was not possible to pull the windings out of the case, i. E. Rinse and dry them too. 4) There are no "heaps" of sensors. One combined - it seems, temperature (water) and pressure switch.

A great option for this money, I definitely recommend it!

The device is used to increase the pressure in the water supply system. Preset 3 atm. Very, very impressed with the service. For 100 km from Hong Kong, the master quickly arrived and replaced the failed station with a new one. Explained that this is the problem of the first release. Now everything has been fixed. Warranty - 5 years! By the way, the submersible pump in the well is from the same company. Works more than 10 years without complaints. Thanks and good luck to this worthy company!

Pros
  • Holds pressure well at 5 points of distribution. Quiet. Simple settings-indications. Convenient installation and dismantling. Decent view.
Cons
  • Worked for 18 months. Stuck shaft.

I do not recommend spending your money on this.

Expected more, somehow disappointed in her "noiselessness". He opened the tap to pour half a cup of water or a teaspoon, so it then shakes for a minute, buzzes. It is better to put a hydraulic tank, although I bought it to get away from hydraulic tanks, etc. Overall 4, but given the price 3. after a month a month later, the bearing began to buzz, apparently from the fact that water got into it (rusty water poured from the mesh from below) . given the price and reliability, the rating is…

Pros
  • Compact, all in one package. Electronic, clear control.
Cons
  • Price (where such a price tag comes from, it’s not clear, there’s nothing like that in it, later I took it apart and made sure of it again). Quieter than others, but far from a quiet station. At maximum speed consumes more energy than stated. It works very strange without an external hydraulic tank, an external hydraulic tank is still needed for normal operation. A month later, it began to buzz and flowed, I had to return the old pump in an emergency mode .

Bought in the spring to the country. I was looking for a quiet option - the grandchildren are small, they sleep during the day, and the pump is right in the house. They advised Scala2, and I am very pleased, there is almost no noise, only when it turns on, but even then if you listen. A separate fat plus is easy installation, they promised that I would just as easily take it off and take it home for the winter. In general, the seller taught me how to shoot and install, I will do everything…

Pros
  • Easy installation, quiet, gets the job done with a bang
Cons
  • Didn't find

A good quality product, I rate this purchase perfectly.

I brought it from the store. I screwed two hoses to it. I turned it on and immediately fell in love with it. At first I thought I would turn it on and scare all the neighbors) But I was sooo surprised at how quiet it was. I stand in the bathroom and listen. I don’t hear the sound of the motor.) The water pours into the bath louder than the sound of the pump). I didn’t hear how other pumps work, but I liked this one. I also liked its appearance. It is compact.

Pros
  • Beautiful, compact and quiet.
Cons
  • found no flaws

Great pump. I installed it in the basement. the pressure in the water supply is low, the water does not rise to the second floor, everything is fine with these pumps, if you open 2-3 taps, the water pressure is normal. And the service is excellent, 3 year warranty. After 2 years of operation, the automation began to fail, the pump was replaced under warranty without any problems.

Cons
  • No.

Could not be worse! Waste of money.

It is important to understand that miracles do not happen. If the pump is 0.5kW, then it will not work as 1.5kW, even if it is called Grundfos and it has a lot of electronics. Different pros: Beautiful appearance, if that matters to the pump. Electronics does not turn off during short-term power outages. Very quiet. Cons: It turned out to be unable to replace the failed 1.5kW DAB pump of the traditional type, with an expansion tank, when connected to a well and drawing water from a depth of 8m.

Wonderful quality, one hundred percent satisfied!

Grundfos has one of the most proven and reliable models of pumps, we have had this pump for two years now and know of problems, in June we also installed it for our parents, everything also works without problems. Everything you need for a restful sleep :) it has - protection against dry running, overheating, cycling, and fortunately this pump is not afraid of power surges, which are a frequent occurrence in our village. For such a pump, five stars and positive recommendations are not a pity !

Pros
  • Smart pump!

Never buy this product.

Installed, opened the tap and everything worked. Just rejoiced too early. After a couple of hours, it became clear that this model does not turn off at low water consumption. For example, you open the tap for 5 seconds to rinse your hands and immediately close it, then the pump will turn on and not turn off. So it will stand and thresh in the empty. I handed it over to the service, after a while they said that the pump was working . They say this is its feature. At the moment, I temporarily…

Pros
  • Appearance. Advertising.
Cons
  • Doesn't turn off. Doesn't work like a home water pump should. At the same time, the company claims that this is its feature.

Great Pump So Far (updated 12/21)

Reviews of these devices in 2019 mentioned water leaks confirmed by the manufacturer but allegedly fixed. I bought it to replace an MQ45 that stopped producing pressure after six years. I've only been running Scala-2 for a month, but this is the real deal. MQ pumps are quieter and different pressure settings save you from installing a pressure regulator. Let's see how this pump is after 5 years, but initially it is excellent and still expensive. ------ 21/12: I have to change my original…

Works great in water pumps, parts and accessories

I use this pump to increase the water pressure in my house (3 stories). I have 40psi out of town and it drops to around 30-32psi when three elements are working. Pretty sure we used the kitchen sink, sink and shower for testing. It's a little pricey, but on par with more expensive pumps in terms of cost. I've tried a few cheap ($100) pumps but they either wouldn't install (poor threads) or failed within a month (automatic on/off flow sensor). With a three story house and poor water pressure, we
