This pump is a workhorse!
Excellent product. Super quiet, very easy to install, perfect fit for my setup, very well made. It comes with a rubber base to absorb vibrations which makes it quieter than it already is. I’ve been using it daily for about a week now without any issues. My daily use is basically to water my garden which takers about 30 minutes of continuous use and supply a toilet and a sink that are off grid. Suction head of my setup is about 2 feet and the other end head is about 10 feet, no issues at all, pressure is great and the auto shut off works flawlessly. Mine is powered by a small battery bank of about 50amps that is connected to a wind generator so is completely off grid. If you want a quiet, powerful, easy to install, great quality 12 volts pump; look no further this is the one you need!!!

Abusing this pump and its still going
I work in a quarry and have this for dust suppression on a crusher, been using it the past month now it's dry and it's running 8-12hrs a day 5 days a week. Most it's pumped in 1 day is about 4k litres with the bypass and pressure screwed to the max. It's running 1-4 nozzles (2 sprinkler and 2 hand type. the sprinkler in the picture is giving more water than it looks as its windy and hard to see where its that fine a spray) depending on how dry it is and sucking water out of dusty ibcs. Not much else you can ask of it when the pump it's replaced was 7 grand. The spray from the hand type in the picture is with 3 nozzles turned on at once on a flat setting.

Die beste und leiseste Pumpe die ich je besessen habe, hoffentlich hält sie auch länger.
