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 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 |

Compact and quiet station for home water supply
The key advantages of the Grundfos MQ3-45 pump are its compactness and quiet operation. The manufacturer managed to achieve small sizes by installing a small water pressure tank (with a volume of only 1 liter, that is, it is, in fact, just an expansion tank). Therefore, when estimating your expenses for organizing water supply, it is worth adding to the price of the station itself (already quite high) the cost of a water pressure tank with a volume of 75 – 100 liters, necessary for its operation.
"Pros and cons"
The pump is fully equipped with automation that ensures reliable and safe operation of the equipment. The station has thermal protection and protection against dry running. The engine turns on very smoothly and does not overload the network at the time of starting. The motor is cooled by pumped water. Thus, the station can even be placed in a non-ventilated pit or underground, and it will work there without overheating. The pump is self-priming, so there should be no problems connecting or turning on after a long period of inactivity.
The disadvantage of the Grundfos station is its "capriciousness". It is sensitive to the quality of the current (in a dacha cooperative, the voltage can “jump”, and therefore you will have to connect the pump through a stabilizer with the appropriate power). No less "finicky" device and the quality of water. There should not be any inclusions in the liquid, therefore, grids, filters and check valves recommended by the manufacturer must be installed at the inlet to the system.
Great choice for a private home
Grundfos pumping stations work great if installed according to the instructions in compliance with all rules and regulations. The quietness of the equipment and the reliable operation of automation will make the presence of the pump in your home almost invisible.
