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.

I ran mineral spirits through this pump into a clogged A/C condenser. Powered the pump via a bench power supply. I ran the pump for about 10 hours stopping every couple hours to blow the condenser out with compressed scuba air. Even back blew through the pump several times. After about 10 hours of use it quit pumping. Removal of the 4 screws on the pump face revealed biological material in the impeller which was easily removed and pump easily reassembled. Pump functions as new after removing debris from impeller.

Surprisingly durable. I am using these to pump water for my cabbing machine for lapidary work. The water frequently has small rock particles and such in it and the pump keeps working! I have had to clean the impeller once but it immediately started working again.

These pumps do not work at all. They could not even pump water on a horizontal surface I can’t believe any reviews on these things Absolutely terrible

Great little pumos for the price but quit working in less than a year. They are cheap enough that I just bought a other set to replace the dead ones.

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.

These seem to be decent little pumps, but quite small. They may work out to slowly circulate water in a solar hot water still. Reviews were pretty decent, and most were running a fountain of types. Hope they work out, just wanted a slow circulation from the coils back to the barrel, will have some gravity to help this along. Power being supplied by 12vdc battery being charged via a solar panel system and actuated by a small DC thermostat and probe set for temperature on and off.

They work very well, I put a fine mesh at the suction end to preventing pebble from stopping the moto

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.

Best value fountain pumps 2 4 1 $

Great little pump! Very happy

This pump is great. It's small a in size but powerful in its pumping. I am using it to pump dehumidifire condensate to drain.

These pumps can run off Molex and work pretty good for PC water cooling.
