HiLetgo 2pcs Water Pump 240L/H DC 12V 4.2W Micro Brushless Pump 3M Pumping Head Ultra Quiet Water Pump for Pool Aquarium Fish Tank

Quiet, pumps well. Picked up a 12V AC/DC wall wart from the bin at goodwill for 5$ to run it, soldered it on, runs great. Uses 1/4" ID hose. I bought it as a miniature sump pump for a problem corner on a patio, and it is driven by a water level sensor, this is where the wall wart plugs in.

Pumpin up pumpin up pumpin up n pooom pin. That is what this pump does. submerged i hear nothing and it pumps water in my cooling system in a 3/8 pipe as expected. speed cannot be controlled by a dc speed controller. on off.

Great little pump! Very happy

I've built an a/c out of a cooler and I'm using this pump to circulate ice-cold water through a computer cpu radiator/fan. It appears to be built well and operates quietly. It has enough water flow to cool down the inside of a small single engine airplane. It has lasted about a year now which is more than I say for other products I purchase. I believe this is a good value.
