UPDATE ● Tough Little 12volt Water Pump from a Toyota Prius
Вставка
- Опубліковано 5 жов 2024
- ● found this powerful little12v water pump at the wreckers in a Toyota Prius and I tested it on a 12volt source and then tried it on a 12v solar panel. It's called an inverter coolant pump. It's from a 2004 to 2009 Prius.This little 12v pump is located just behind the drivers side headlight under the hood. I connected it to a meter to get an actual amperage reading while it was pumping water connected to a solar panel and then to a 12v battery charger power source. It's a very quiet little water pump you can barely hear and has good output. Would be good for indoor hydroponics, outdoor hydroponics, pond pump or anywhere you need quiet constant water circulation.

Specs when connected to 11.2V source
● Creates 4 psi of pressure
● Head pressure: approx. 8ft. (2.4m)
● Volume:
6ft. (1.8m) .9 us gal (3.6L)/MIN.
4ft. (1.2m) 1.6 us gal (6.0L)/MIN.
2ft. (.6m) 2 us gal (7.8L)/MIN.
● Inlet and outlet pipe size is 5/8".
● It will not run in reverse. It will spark if connected wrong but will survive.
● Runs quite nicely up to 15V (I had it connected to 17v and still ran fine but to be safe, stick to max.15V).
● With the female terminal socket at the bottom, while holding it in your hand, the right side is positive and the left is negative.
● Rubber mounts are easily pulled off of the pump.
● It is a brushless dc motor.
● Runs very quietly.
● When at the wreckers, look under the hood behind the left front headlight, that is where you'll find this little pump.

did you even see how many gallons a minute this lil guy is pumping?
When my uncle was a mechanic at a Toyota dealership, he gave me a few of these pumps 6 yrs ago because they were recalled in a Toyota prius model (that i cant remember) so he gave me a few of them and still have them and they work great!
Using one to cool my Exhaust outlet on a cummins 6bt which is keel cooled ..It actually has been pumping raw sea water for more than 500 hours and never missed a beat ...Sweet device
That's cool! Good to hear.
I want one to water a 2 tennis court garden using a half inch hose. As long as i can get 4 gallons per minute it would work. but it would have to be 50 foot hose.
@@HealthSupercharger Did you get your solution?
Thanks for the additional information! FYI, the "thin film" around the shaft is called a fluid bearing. It's the same concept as the oil in your car's engine around your crankshaft bearings. The flow of the fluid creates a boundary layer at the surface of each bearing and allows the metal of the crankshaft / cams / turbocharger shaft to float without contacting the bearing material.
Exactly. Thanks for the good explanation.
Is this at all related to capillary action/ and or surface tension?
Surface tension is a product of polarity of molecules. There's more intra molecular attraction, so they pull together. Being that the pump is submerged, I don't think that surface tension is going to have much of an effect.
Capillary action is the ability for liquids to crawl up between surfaces due to the intermolecular forces of the medium. It's not the same thing as surface tension, but they're related to each other.
The Boundary layer has to do with fluid viscosity and fluid flow. It's a subject matter taught in fluid dynamics in mechanical and aerospace engineering. It's essentially the drag from a theoretically non-moving layer of fluid on each surface causing drag on the fluid as you move away from the surface as a product of shear and/or viscosity of the fluid medium.
Water (as a liquid) has a relatively low viscosity (as such, it's quite the poor lubricant) so to maximize the effectiveness of a fluid bearing, you would want the tolerances between the shaft and wall to be relatively tight.
The higher the viscosity of the fluid medium, the more lose you can have the tolerances between the bearings. That is why with modern performance oils, you can have tighter and tighter bearing tolerances increasing efficiency of the engine and longevity of its working life.
Thanks for note. Nice job.
Thanks to your original video I've been using one as a saltwater pump to cool a diesel engine on a sailboat. 2 years now I think. Thanks, it works great on the 75hp NA volvo penta. No corrosion noted at this time
Wow. That's great. Others have asked it would be a good coolant pump for an engine and I said yes. That proves it. Thanks.
Thanks for mentioning that. I'm considering using it for a raw water cooled Yanmar 8 HP lump in my sailboat. It may pump more than I need so I'll add a ball shut off valve up stream of the pump to control water flow volume.
Hiya mate going the same roots you what size pipe is it please ?
@@stevepottercanveyislandess6223 I believe it fit 5/8 heater core hose
Thanks for posting this. Going to use one for an intercooler water pump. OEM quality at Junkyard prices. Love it. So quiet too.
Good luck!
@@chrisnotap I blew it. But also discovered the gen3 will work good ^^
Did you find the flow drops off if you put your thumb over the outlet does the flow drop a lot? I killed my gen1 and the gen3 have 2 extra wires for control... seems like it runs full tilt (hoping full tilt..part of why I'm asking) without a signal. It also stops when it doesn't have water going through and restarts after like 30sec.. it is a lot fatter in the motor/controller area though.
Also did you measure flow at all? My gen3 sucked down a gallon in under 7sec with no head. But once I put my thumb in front of the outlet flow dropped off a lot.. hoping running 2 helps.. might have to get another gen1 and test side by side and double check about the control wires but if it did a gallon jug in under 10sec that's over 360gph which seems like a good amount.
I'm using one for my turbo and waist gate. There water cooled. And it's own rad
This video helped me a bunch because I have a simular auxiliary cooling pump from a VW that I can get to spin when I apply 12 volt but I couldn't figure out why it wouldn't pump water out of a bucket , so I need to put water into it to prime it , Thanks for the video
Hi Chris, I think you are just the right person to help me, since youtube suggested you to me. haha . The toyota agent replaced this same inverter water pump of my Prius 2007. When I collected the car, I heard this humming when I started the Prius Hybrid. Nothing else is turned on at that time, and usually it is dead quiet ( for the last 10 years ). I thought it was odd and brought it back to the agent. They check it again and told me all is well and that the noise is indeed coming from the water pump and it is normal. I am perplex since I drove for 10 years or more without hearing it and now after replacing this new one, it was loud enough to hear it. So now I no longer have the same quietness as before.
I am not convinced with their explanation that this pump is meant to be working all the time and therefore it is on the minute the hybrid system is turned on without having to have the engine running. I thought it was odd to be so since it will be drawing and draining the battery power if that's the case even on park mode. Could you please advice and put my mind at ease.
Am I supposed to hear any noise from this pump from inside the vehicle? I noticed you stated in your intro above that it is a very quiet pump. And should it be running even when the vehicle is at park mode? Look forward to your expert opinion. Thank you very much.
The humming noise is your aunty in the back seat, she was tricking you with with hum ventriloquism.
love this little known idea. currently setting it to pump water/coolant thru my "water to air" intercooler setup.
I assume it's plenty strong to run an A2W intercooler on a small car?
Haha found this video looking for a pump for my intercooler setup as well!
What is the inlet/outlet diameter?
Just got the answer fom OP, it's 5/8" (16mm)
My pump has similar aspirations! When it comes time to dial boost from 12 to 20... gonna need that flow...and a big ice chest ;)
Partial to meth injection too. Clean and safe with plenty of benefits and few downsides, save the tank going dry/needing to fill said tank OR the controlling equipment failing catastrophically. :) The benefits of adding alcohol to the chamber helps control knock. The water also draws heat preventing knock and adds a steam engine effect during the combustion event through to BDC. Doesn't hurt that it steam cleans your intake, ports, upper/lower chamber and the piston tops either. :D
Will this work as a water to air cool pump on a supercharge
Fantastic Chris, this is how things should work " SIMPLE "
So pleased I came across this great little pump - huge thanks for the videos! I am currently using the pump to run an artificial stream in my garden. It lifts water about 2 feet up from a pond which then cascades down a small wterfall before running back into the pond. I power it using a 50 watt solar power and a 12 volt car battery. It runs constantly during the summer months (ie. when there is enough sun). Hope this helps others to make use of this brilliant little pump!
Have you done any tests where you use the pump to generate any kind of pressure? I'd love to see what kind of pressure it's capable of and how the amperage reacts to an increase in pressure.
Looks like the perfect pump to cool my dual controllers on my electric small block Chevy crate motor I am prototyping.
thats awesome i want to use a solor panel to circulate water for a cooling project i want to do and this seems PERFECT
Great videos! Super informative, WITH PROOF AND EXAMPLES! can't beat that.
Great video including the current draw was nice too.
Thanks for the update, really good additional info. Just an FYI, I had problems viewing this video for some reason. I tried to view it on my phone (with full network connectivity) with no luck and on my WIFI Samsung tablet with no luck. Was finally able to view the video on my laptop (on the same wifi as my tablet with no changes in signal or settings). Not sure what's going on, I've never experienced anything like this before on UA-cam.
Thank you!
great video
Ideal for aquaponics hands free, with solar panel
It's a brushless motor. If you get some of that magnetic film you will be able to find out how many poles are in it.
Thanks found it interesting may try that at brother camp see if it will pump up hill about 20 ft lake-barrel for outside shower.
Have a look in the description. Unfortunately it pump that high. Only about 8 ft of head.
Amazing video, thanks for the info !!
Thanks for the specs! Good job
Any chance you could tell us the number of the connector?
What would you need to regulate speed of the pump? I want a circulating pump to use with an engine heater, if you could run that at about 20% of the amps and still get some flow it would be perfect.
Does it work in hot water?? Thinking of using this in a camper-van hot water heating system. Cheers
Bit late to answer but it is designed to work in a cars coolant system so hot water will be a breeze for this
Nice video, but I would like to know the flow rate. (Flow rate is not in description as it needs to have units of time somewhere to know the rate). Thanks.
Sorry. I forgot to add that. It is per minute.
Just info....
I just bought new one Prius EWP (but second grade made in ch*n*) and try measure flow rate of that EWP, flow rate about 19L / 1.4min ..or.. 13L / min.
Amazing...😁
Okay, so I f'd up and reverse pol'd my gen1 pump (white is ground? black is 12v? wtf) anyway, my only other j/y option currently was a gen3 pump. Has two more wires for the ECU to control pump duty and watch rpm, from my testing, it will simply run at full duty without a signal on these wires. +12v to blue and gnd to wht/black. Should give people a few extra options to get these pumps. The gen3 pump does look better and is likely improved in some ways. I'm not 100% positive it's running at a full 100% duty but it seems to flow as much as the gen1 did this way; I didn't measure, just observed, but, WOOP
Did u ever find out if the gen-3 will hold up running just the Blue+ and white/black Neg wires?
@Kirk Frith yeah seems to run fine like that, just don't reverse polarity. Pump will stop after 30 sec or so if there's not enough flow. Use a low amp fuse (like 2.5a or something) to verify polarity if you want i can't guarantee what I said was 100% accurate with regards to pos/neg. I may still swap it out with a better pump for intercooler tho not sure.
I would like to see how much power would be generated by spraying water to the back side of solar panels ? They say cooled solar panels generate more energy. Improving the efficiency of your solar panels is a desired effect. I just wonder if something like this pump could spray water to the back side of the panels where the water would trickle back to the pool and be reused again to cool the panels.
Check the specs in the description. It may give you a better idea. Sounds interesting.
If you cover the back of the solar panels with some find of close fitting cloth, glued onto the surface say, you then only need to supply just enough water to keep it slightly wet. Then give it an air draught from wind, or fan, and the evaporation of the water from the cloth will cool the surface way better than sprayed water. Depending on the water quantity required to keep the cloth wet, you can use small peristaltic pumps from air conditioning systems or wherever. The advantage of these are they can self prime a fair few feet, and can pump. To a head of tens or twenties of feet.and also for a given rpm supply an exact quantity of water.
Experiment with this evaporative cooling!
To get an idea of it's effectiveness, put on a thin cotton clove, wet it, then stick your hand in the draught of a household fan. It will get bloody cold.

What is the pull and pay price ?
I see DIY lawn fertilizer boom sprayer designs - tank/tote in a tow-behind wagon for lawn tractor - with a new (roughly) $100 pump and relief valve recirculating system. Wonder how well this would work in such an application.
Hello, Thanks fr all info. you have an idea of the flow rate?
8ft of head is pretty excellent for a pump that size😮
Im thinking of putting one of these on a small tractor I have.
And of course he can put it back together!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Would it be hard on this little pump to be operating at full speed and let the thermostat open and close to circulate coolant?
Is this pump still running 6 years later?
Have new pump ohms at 9k I think, old one seems to zero......Failed indication?
Can you please post the part number on the connector? I have look and look and looked some more but cannot find a matching connector online.
Great video! could you possibly give it less power to reduce to flow a little? wanted to use this for a project and do not need that much flow. Maybe have it rigged to something with a knob to control the power/flow rate?
+mike frontuto Yes. It seemed to work quite nicely at lower voltage and flow was reduced. The only thing is getting it to start on low voltage. it won't. Needs a bit higher to get going then reduce after going.
so could be it possible to make something so that it starts on 12 volts, but then regulates the power down to the volts needed to get the desired flow rate? Thanks for the reply.
Can this water pump be slowed down for lower pressure?
Sorry ....already informed at desc.. 😅
(Your video inspire me to use this EWP to replace my mecanic WP. Plz inform wiring (+ / -) this EWP ?)
+ / - That info is in the video
@@chrisnotapok. Thanks, chris
What do you do if sand or leaves get into the water?
cry
I recommend a water filter or even just a mesh wire thing you can get out of window frames
Hi Chris, I am a subscriber and would like to know how to get the connectors for the water pump. Thanks.
Had bit of misfortune with the original pump from the wreckers. Seems like it was already stuffed because the fishes got really freaked out when i turned it on. Did not last long before it completely died, so i bought a Chinese knock off instead, but it only last 2 years before the internals began to disiterngrate and jam it!. I pulled it apart and found the fragments jamming it and washed them out and the magnet started spinning freely again. Only prob was I used a chisel to break it open and warped the suface/s so there was no way of successfully reassembling it. However, since then i've experimented with some other brushless pumps which according to my test/s use less Amps as per the Prius Pump. By various tests i mean, like Min voltage 10.5vdc to Max 14.8vdc
I will be making a video soon about it. the pros/cons, costs etc...so i hope anyone keen about pond pumps, maybe interested. :)
Cheers! MIck
Interesting . I will watch for that video. Thanks.
Hey! Sorry to comment on such an old video. Is there an easy 12v wall source that works for these? I am not electrically savvy and don't want to burn my house down lol
Would this pump be able to handle hot water/coolant from a small 7 HP diesel generator?
It should handle that quite well.
@@chrisnotap awesome! Thanks.
Just info....

Oops. Just realized you saw the update video too. Stats are in the description.
the water pumps out of the middle tube ?
That's the intake side.
I'd like to hook up a 12v bilge pump to a solar panel to run my solar pool heater. Can you recommend the best way to hook it up? Can it be direct ot through a battery that is being charged by the panel or is it more involved? Thanks
Do you know how many meters the pump can raise water?
Lots of info in the description.
@@chrisnotap ah thanks very much, I didn’t see that 👍
Can this be used on an aquarium or sump will it need a good cleaning so it don’t kill the fish or not worth the risk
Sorry. I don’t know the answer to that.
Can i get electric shock if i touch water
No. It is only 12V DC.

I literally tried searching for anything on amazon to buy that might beat this and well lets just say this wins all the way plus it already does what i want it for, move coolant.
Every aquarium pump one ebay is better than this pump and is cheaper and will work longer and there ajustable so prius pump vs aquarium pumps the aquarium pump would win everytime Lol for 1 this prius pump is like 30 - 60.00 also its not self priming it's also an inline pump so its not supose to be submerged under water so it wont work longer than a year or so unlike my aquarium pump that is 1200 GPH ajustable flow rate was only 22.00 and has been running for 24hrs a day 7 days a week for 12 years now thats a good pump and there only 22 bucks lol so a prius pump is only good if you have no mo ey and a junk prius laying around lol
Does the pump have to be submerged? I'd like it to suck water from a tank and shoot it out for a shower.
Must be submerged. Will not self prime.
Hiya mate du know what pipe sizes are please
They are 5/8". I added it to the specs in the description. Thanks.
If you connected an air tight hose fitting to the pump and put the hose in the water... would it suck water through the hose to the pump? Or do you have to submerge the pump?
noted you said wouldn't lift water which is a shame as I would like to lift water from a river to a water butt any thoughts on a solution? as I need 12 volts, no power available
mark williams try a ram pump. Google it
My Bad, I know what it's called, sorry.. Will this handle HOT water,,,, say up to 120 degrees F ?
no problem.
Is this 12 volt water pump the highest flow rate or is there another brand/ version that outputs more water per minute ? Ty
That's a good question. I really don't know.
How's the Prius run without the water pump?
Starts vibrating just like the pump w/o water.
Cool.
Here is the $64 question.... What is the head height?
Description.
@@chrisnotap8'..... Gotcha. Ty
I connected mine to a computer power supply adopter 12V , 2.5 A
Sadly it burnt out in like 30 secs
Any chance you ran it with no water in it?
@@BuffMyRadius I think his amp test showed 17 A? Ur 2.5 A source have done it.
I mean 1.7 A
Is this thing safe for fishes?
That is something I can't answer because I don't know.
+Chris Notap how much did you get it from the wreckers?? Usd??

mid 2000 bmw suvs have that as well its not quite as big as that one so its probably not as powerful
Interesting. Yes, this one really puts out the water plus it has the Toyota reliability.
Have you happened to measure gallons per minute?
In the description.
about 3. should be at the 8 ft, but I don't think this will do that,

Hom much Watts does it draw?
12V x 1.7A = 20 W
AFTER replacing the INv Pump, it runs when I am driving around! the Old one was running and while driving as well and finally failed! Does anyone knows about this?
it should be running its part of the hybrid system and the inverter is constantly being used to drive the motors.
How many GPM it puts out, for many using in in a high banker

I tried. I see some information about head pressure, and various 'feet' dimensions, but can't translate that to gallons per hour. I'd take liters if you have that. I'm not trying to be lazy or difficult. Others have asked, too. I'm very happy that you posted the video. If I'm missing something, please help me to understand.
Thank you. That pump looks like it is pumping way more than that per hour. Maybe GPM? I'm not sure why he's resisting clarifying, but...it's his video, I guess.

Thanks a lot! :) I'm considering this pump for the intercooler on a custom supercharger setup si it's a usefull info so I know what adapters to buy as my other componants will have 3/4" ports.
I.D? O.D?
I was asking of inlet and outlet ports of the pump so I believe he answered the O.D, that would make more sense.
I needed 3/4" inlets and outlets for my project so I chose a Bosh pump ref 0392020077, used in many Mercedes Benz cars as auxiliary water pumps, you can find used ones for super cheap anywhere!
