Mini 12V DC Brushless Submersible Water Pump Review and Disassembly

[@cassandranoorman7154]

Thanks! I was worried that it might contain aluminium but I didn't want to open mine up. It was really good that you show that it's just plastic and stainless steel inside.

[@Chrom35kull]

I've just bought one of these as an emergency replacement for my watercooling pumps in my PC, i was that impressed that it 1. did the job and 2. survived up to 55c over 10hours that i bought another. for £10 each delivered and it's already lasted longer than the £50 integrated pumps in my watercooling.

[@leefiles]

wow! that's warm considering these were meant for pond water.

[@A7XstefanA7X]

is it quiet enough to be used in a pc? i ordered one bc the pump in my corsair h100i died, i plan on just splicing it in there

[@jayrcool8256]

It suppose to submerge in water to prevent overheating

[@NOSrommel]

Just ordered this and im goging to use it with a solar pannel, battery and solar controller wich i also ordered for a hydroponics project next year. Nice vid thanks:)

[@leefiles]

cool. I've been playing with my own concoction of hydroponics. The water movement part is the easiest. I just need to get the water chemistry right. Like nutrients and rotting roots.

[@truedesireelements2040]

Thanks so much for everything. I was wondering if I should purchase this or not. BUT after watching this, I know for a fact I want to purchase a few now. I appreciate you explaining everything about it. The pros and cons and explaining why others might have gave the bad reviews that they gave. I love everything I see about this pump.

[@leefiles]

Thanks

[@truedesireelements2040]

No problem at all... Thank you again...

Awesome review on something so inexpensive, been seeing this online but wasnt to sure about getting it. Plan on putting this in a 120mph rc build to liquid the motor. Thanks for putting my mind at ease!!

[@brushlessdcpump]

Pretty good sharing, I think the most advantages of this pump is the portable, low consumption and long life. But it is not self-priming..

[@Synthematix]

These are great little pumps but you have to be careful with the wire, it will break easily next to the pump if you keep bending it and i dont think you can replace the wire if that happens as the pump is thermo sealed. these will actually run on 14.2v pretty well for around 6 months constant, 12v they last about 18 months. with an "L" push on fitting they will fit directly to the back of a watercooling reservoir for cpu cooling, they are also passive meaning you can run two together if one fails the other one still carries on because water flows straight through them when they are not powered.

[@johnlangdon3281]

+Synthematix I bet you could get some silicone goop and slap a big ol'thumb full where the wires meet the housing and it would make it super safe.. Come to think of it, slime up the area it where it comes apart (if you doh't seee yourself taking it apart anytime soon but even then... just re-apply after putting it back together and scrubbing off old layer) and it would really solidify the waterproof-ness :)

I bought this pump and found it has one major issue. In order to work, it has to be submersed. It cannot suck worth a hoot. It does lift water well enough though as long as it's lifting through a hose otherwise its a maximum 8 inch lift.

[@leefiles]

It is not expected to self-prime. Those cost much more.

[@raisagorbachov]

[@ronaldd.1355]

@@leefiles What do you mean for "self prime" and what is that for or needed for? (excuse my ignorance) thanks in advance

[@leefiles]

@@ronaldd.1355 Self-prime is what "Zephod Beeblebrox" originally asked for. The pump will suck water on its own. In non-self-priming pumps, you have to either submerge the pump to get the water flowing or you have to suck the water thru the pipe/hose to get the water started. When you place the pump 's hose in water and turn on the pump, it sucks air. In self-priming pumps, it pulls air as well as water. But they come at a slight cost in terms of money and efficiency.

[@moreirasp]

Thanks so much for everything

[@JoseCarlos-zz7us]

[@LookAroundTravel]

Do you think water can pass through it even if the pump is turned off? I would like the water to pass through the pump on its own, even if it is turned off.

[@leefiles]

Water can still move through the pump even when off if some other source was pulling on it such as siphon by gravity.

[@savetheaspies]

So the metal parts don't get wet? I wonder if this could pump an acidic liquid. Not like battery acid... just like PH 2-3. Like to circulate solution for copper plating / electrolysis.

[@leefiles]

The electronics and coil are not exposed. The magnet and plastic impeller exposed.

[@trelectric3304]

Great demo. I need one to circulate liquid in an etching bath. Looks like 240l/H will paint my walls with dangerous chemicals so I might go for an 80-120 instead. I'm just wondering does the water flow touch any metalic parts inside? Many thanks.

[@leefiles]

It will put a strain on the coil. More heat.

[@lovingtiesto]

I powered mine with a celphone charger of 5 V and 0.5 ampers, is that to low? Can i put one with more ampers or will i burn the pump? Water is not high enough

[@leefiles]

(I have one powered by an old phone charger that supplies 1A) You would need to know how many amps your pump uses. If you have a phone charger that supplies 1A, even better. So if you use a multi-tester (volt meter/amp meter) and measure how many amps your pump uses at 5 volts, you can then decide which power supply to use. So say your multi-tester shows that your pump is using .5 A at 5 volts, then you should use a stronger power supply like a 1A or 2A phone charger. So if your pump uses .5A and 5-12 volts for example: A phone charger that supplies more than .5A at 5 volts will not burn the pump. A phone charger that supplies .1A will burn itself out. If you use a power supply that supplies 24 volts, it will burn out your pump. If your power supply puts out 5 volts and 5 amps, your power source will be fine and your pump will be fine.

[@Diana-xm1dm]

To me at least, it doesn't seem feasible to operated it from a USB charger. Is there a way to attach it to some sort of plug e.g. an appliance plug that would connect to a wall?

[@leefiles]

You can wire it to a wall adapter easily. Any 12 volt AC adapter will do. An old network router's unused AC adapter will do. Wire it with solder. If you don't know how to solder use wire nuts.

[@sirapongweawseetong7995]

Can I use it pump air, use outside water?

[@leefiles]

No. It will burn out. You can buy an air pump in a petshop that sells fish. Or look for it on amazon. If you're looking to go fishing, they make battery powered air pumps.

[@renyeliyap]

Thank you very much.. Can you help me with a project? I have a 5v relay auto shut off overflow switch that runs on a 9v. 1st question: Will that be able to shut off this pump in a event of an overflow? 2nd question: if i run this using a 9v batt, how long will a 9v 900mah li-ion batt last?

[@leefiles]

Wont the 9 volt source burn out or eventually wear out the 5 volt relay, depending on the quality of the relay? 1yes. 2. not very long. Mine uses just over 300mA. So on your battery, it will run about 3 hours. But that's with no load. Once you raise water at a height above grade, it will use much more current. So you may get as little as an hour or less.

[@renyeliyap]

@@leefilesohh ok, so i have to get the same voltage for the relay and the pump?

[@leefiles]

yes, use five volts for the five volt relay. Unless the circuit you called '5v relay auto shut off overflow switch' already regulates ( steps down voltage) down the voltage going to the 5volt relay to 5 volts. See, I haven't see anything of yours yet, so I have nothing ti go on.

Mine goes up to about 80cm before it stops flowing. But it really depends on your model. If you're worried about back-flow, you can get a check valve at a hardware store that carries plumbing supplies.

Does anyone have any experience powering such a pump with a solar panel? I'm using a very similar 12 V DC pump in a shishi-odoshi (sort of a Japanese water fountain see-saw) that I'm building for my backyard garden. The problem is I want to power the pump with a solar panel that produces about 21 volts DC in bright sunlight and a current about 150 mA. Hooking the solar panel up directly to the pump doesn't work because (I assume) the pump needs more amps to run. To solve this problem, should I use a charge controller system and/or a 12 volt rechargeable battery?

[@leefiles]

Alan Falleur Voltage regulator. you can build one or you can buy one on ebay. look for "dc-to-dc buck step down"

[@leefiles]

leefiles It should be a switching type not linear. The LM317T is an example of a linear regulator.

[@alanfalleur6550]

leefiles Thank you very much! What the solar panel enthusiasts call a charge controller is apparently a current and voltage regulator much like the kind you mention. I acquired a nice 8 amp-hour, 12-V battery for very cheap, as the standard thing to do according to the internet is run the pump off the battery and use the solar panel to keep the battery charged. Thus the system will continue to run at night or during very cloudy weather. The charge controller's electronics keep the battery from becoming overcharged.

[@leefiles]

Alan Falleur Sorry, a charge controller would actually work better. You're right. BTW your solar panel measures 21 volts? That would be an open circuit right? You measured the solar panel directly? If so, any GOOD 12 volt charge controller would work. Note that some controllers have terminals for: solar, battery, load. That would work best in your situation. You don't want to kill your battery in a few cloudy days.

[@leefiles]

Alan Falleur I'm guessing you are using an 8AH lead acid battery? I saw some lithium ion batteries that are drop-in replacements for lead acid. But they cost more.

[@milesstarkey123]

leefiles You'll have to excuse my lack of knowledge in the field of electronics: So, are you just using the old cables that you've cut? Would there be a way to build a wireless power transfer system (en.wikipedia.org/wiki/Wireless_power) like what powers a pace maker? (I ask to avoid electrocution by trial) You seem to know electronics pretty well so I thought I'd up the expert factor if you don't mind entertaining a rookies questions.

[@leefiles]

milesstarkey123 Yeah, that would be two coils. Way too complicated for a pump that costs a few dollars. All I added is one of those wall-warts. If you cut the two wires at the other end you have + and -. So if you wired it wrong, just switch the wires.
