Pros

Cons

Good pump, quality
30 March 2019 
The pump has a convenient control unit with light indication. It lifts water well from a depth of 4 meters. It works quietly, effortlessly, everything is automated, there is even a small tank in the pump design. It happened that the water in the well disappeared, the protection was triggered, and it turned itself off. This is a plus for reliability. There are no leaks or glitches. It’s been working smoothly for a year now, I want to install a second grounfos to water the garden, but it’s already closer to summer.
convenient control, has protection, will not work dry
everything is great
use Grundfos MQ3-45 few months
I will never buy this brand again
21 May 2017 
I contacted the service center, ordered a new end seal, replaced it, and a day later it leaked again. The pump has been disassembled and reassembled several times, but the leak continues. I don’t know, maybe the service is weak or the pump is defective. In the store they shrug their shoulders and can’t help.
Only design, works quietly
Less than a month has passed, the entire boiler room is in water, the seal is leaking.
use Grundfos MQ3-45 month or more i recommend it don't buy
