confirmed 12 volt power supply was working.
Tried an alternative 12 volt power supply pump still will not operate.

Highly recommended to makers that need a cheap brushless pump that isn't fazed by PWM voltage control (500hz and 8000hz tested) for altering pressure. I did not test flow rates as that wasn't a concern for my application.
I'm using it to recirculate water for a liquid cooled LED grow light system. The pump is easily strong enough to push water through a small radiator and several yards of piping and tubing to the LED system, even when only operating at 5V DC! I gave it 4 stars instead of 5 because the necks to the threaded connections are very weak without anywhere to place a tool, and the high-pitched whine when running at the full 12V. If you want to use it for short durations or in a non-living space, this should not be an issue. If you want to have it on continuously in a living space like I did, consider whether or not you can use it at reduced power or somehow block the sound before buying. The pump body gets a little warm when running, so you won't want to pad it too tightly if you do opt to try to block the sound. Overall, good pump, does what it is supposed to do. I'll update my review if it starts to act up.
I think I wrote bad review first but I need to correct it. First thanks to Joy and Emma for their responses and Amazon Prime for their help.
I bought two of these items, one with the plug and the other without. These little monsters work well. My problem was that one pump wire terminal went bad, my handy man cleaned them, stripped the wire and the pump quickly went into service. There are no installation suggestions anywhere nor a troubleshooting page. They just tell you to return them, no question asked, and you are good. It is true, you are good.
New installation, on the roof, connect solar panel 30W to charge controller and on to 12v battery. The pump will feed a steady charge from the battery (protects the pump from irregular flow caused by clouds, birds, shades ) and the battery will continuously charge from the panel. This way the pump does not suffer from highs and lows, any motor appreciates this. Bought three more. Why not 5 stars, I believe in accompanying well writen instructions and trouble shooting notes.
We have hard freezes here, so it is drained and kept out of water for the winter.
The later in the summer, the more algae, the more susceptible to failure....
I connected it directly to a 20V, 5amp 100W solar panel, and it works great!
+ At least 6ft head with good flow
+ Easy to connect wires to (I used liquid electrical tape to make the connection waterproof)
+ Well built/ sturdy, lots of fins on the impeller
- The wire that comes with it is pretty small in diameter (smaller than 16AWG), and not as long as I would have hoped (max around 3ft)
- Would like to know the max Amps and voltage it is rated for (handles 20V, 5 Amps with no problem)
Great little DC pump with a decent amount of power/lift/flow
The second time I used the pump, it wouldn't start. I had to take it apart and clean it again before it would get going. I thought maybe I didn't clean it well enough after the previous use. At the end of that brew day, I cleaned the pump and decided to leave it disassembled until I needed it again.
On the third use, I reassembled the pump, connected all my hoses, plugged the pump in, and it wouldn't work. I had to disassemble, turn the impeller a few times to get it going, then it took off.
So, for what it is, it does a decent job. Its super quite and has no issues with wort break material and smaller bits of pellet hops. I recommend a hop spider just to keep larger hop particles from clogging the pump. If you're looking for a homebrew pump, this is a good entry level unit to get you going. Just be sure to clean it well, and check rotation before connecting everything.
The negative side is that the input/output necks are too weak and can be snapped off when plumbing in the pumps. There needs to be a wrench fitting immediately between the threaded portion and the neck to protect these weaknesses. You need to be very careful plumbing these into your system.
Don't have a flow meter so can't estimate flow, but discharge piping on two 1 x 2 meter thermal panels stay barely warm to the touch when the pump is running so it's moving some heat. If I shut the pump off for a few minutes the pipes can get very hot.
Even though I don't have it installed yet I did a test..... the unit was submerged in approximately 24 inches of water. It pumped up to the water level @ 24 inches.. and then an additional 24 inches above that for a total of 48 inches above the pump.. timed at 1 gallon in 32 seconds
That is more than adequate for my intended application.
