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.

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

This was used for circulating water from a hot tub through solar heating panels. I actually used two of these pumps (one feeding the other) because the solar panels were on a roof approximately 16ft higher than the pump location. The pumps were also controlled by a solar panel so they automatically turned on and off.

Moves water, but not with any pressure. Useless on my fountain.

pump stopped working less than a month. only on 2 - 4 hours a day. bad quality. Do not recommend.

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.

I ordered this pump to replace an over-priced March pump used for cooling the compressor for my sail boat's refrigeration system, which had quit working. This little pump is doing great so far at 1/10th of the cost of the March pump. I ordered a second pump as a backup, in case this one has a limited operational life, but am still well ahead on replacement cost for the March pump.

I used these pumps in my hydroponic greenhouse all year with now problems.Lots of lift with with low power consumption.

well it worked, a bit, a tiny bit. may be okay for water feature circulating a few feet. that's it.

Still tested it out though, and works well. Ill find a use for it. The pump requires flow from the inlet - if you're going to install this above your supply look for a 12v RV pump

Was surprised by how well this little pump works.

Good pressure for small pump but only lasted one spring and summer. It circulated water in a fountain.
