DC 12V 1/2" Brushless Magnetic Drive Centrifugal Submersible Water Oil Pump Ultra Quiet 800L/H 5M/16ft for Fish Tank Fountain Pool Pond Aquarium Solar Water Circulation System

Delivery rate at 2 m head through 16mm pex was about 3 lpm. I plumbed 2 pumps in series and realized about 5 lpm at 2 m head. THIS PUMP WILL MOT PRIME, EVEN A LITTLE BIT. All air must be purged before it will operate.

The pump performed as advertised for about 6 weeks, then it died seemingly overnight. Not something I'm willing to buy monthly to keep my fountain running. Buy something with better longevity.

Trying to figure out, real-world, the best small water-pump for hydroponics/aquaponics/etc with low enough current draw to utilize a solar (PV) + battery setup requires a little trial and error. The smaller inlets/outlets can become clogged too easily during algae blooms or late filter changes/cleanings. This is the smallest pump I could find, with enough flow, which LASTS. 1 of 4 was DOA or defective, but it could have also been from a power surge. Love these pumps. They’re my go-tos, for now.

nice little pump. easy to install, works all right. only thing is the pressure output seems to be low, not sure it is up to the specification. other than that, it works.

I dunno. I once bought a "large" bench vise that turned out to be so big I literally LOL'd when I managed to get it out of the box. This pump had the same effect on me, but for the opposite reason. I figured some potential buyers (and my fish) would be curious to see it with something to judge the size. "For scale". You'll have to read other reviews for comments on durability or suitability for your application.

Works beautifully as a seawater pump for the refrigeration on our boat

After installing the pump I was very happy. Space is tight and this pump is small enough to give me more space. Once I got the system filled I noticed the pump was louder then the one I replaced. Did burn in test on PC and all worked great for the first couple of days but I woke up today and the system shut down. Tried to start it up again and the pump was making a high pitched screeching noise. Specs says the pump can take the temp but it failed. It also does not seam to have the a head height of 4m. I was getting a very low flow rate from the pump too only about 50L/H the pump is rated at 800L/H this is quite a drop. Returning pump since it now makes a very loud noise. Pump ratting states good up to 149F.

Wanted to get the fountain going again, this pump has just the right flow for relaxing sounds. Running off a DIY solar setup: Solar fountain setup for better deck zen 🙂 (2) Cheapo 25watt panels for morning/evening charging. (1) Cheapo charge controller & 7Ah LifePO4 (1) Cheapo pump off AMZ, but it does the trick!
