KOOBOOK 1Pcs Ultra Quiet Mini Brushless Motor Submersible Water Pump DC 12V Lift 5M 800L/H Multifunction Threaded Water Pump

Very quiet

I have two of these, both are performing very well. I use them on a hydroponics system. One circulates the water in the main tank, the other pumps the sump back in to the main tank. I have had no problems with either. Both are full time submerged. The only thing I would like to see changed, is for the wire leads to be somewhat longer. The pump comes with 18 inch leads; I would like them to be more like 36 - 48 inches. That would eliminate the need for submerged connections. Overall, an excellent pump for the price.

I didn't like this product for my application returned

I tried it yesterday. I have a 200 liter barrel with water at my garden and the pressure was very low to water plants. But this pump changed it radically! It's not making pressure like in the pipes from the city, but watering plants from the barrel are much more comfortable now.

The pump housing cracked and the water shorted out the pump in 2 days.I live in the Midwest and decided to utilize one of my 12 volt solar panels to circulate through a short section of black garden hose to heat my pool for free. It worked like a charm for exactly 2 days. Somehow, even submerged in the pool, the pump overheated, the housing cracked, and shorted out the unit.While it worked, the flow was slow but it was OK for my purpose as it allowed the water to heat up a bit more and it accomplished my goal. The pool water was 76 degrees F going in but 90 degrees coming out... so that was a win on the design. That may not seem like much but running like this day after day (if it would have lasted) can make a big temp difference, especially when coupled with a solar blanket to insulate at night. It was great because when the sun went down the solar panel stopped supplying power, so it was like a dawn to dusk monitor built in. However the longevity was a joke.I'll be trying out a different brand of 12v motor that hopefully will last.

In addition to being a great little pump for an aquarium it seems that many water makers for boats also use these pumps for booster pumps.Easy to wire and the plumbing connections were a breeze (thankfully!). The install probably took less than 5 minutes.Highly recommended 👍🏽Helpful? 👇🏽

It IS brushless and magnetic drive !I did not check available head height however it works great for me with a 6' head.

It is a nice pump, but there is no information on fitting size to connect it, tried 1/2 " fittings at hardware store but they don't fit (they were NPT threads) I found it takes a 1/2" BSPP connector. After getting the correct fittings I tested it and it does work as described. A little more information on connection fittings in the description would help.
