This is basically a just a homemade water pump made from some things you might have around the house. Its useful for many things. This isn't my idea, so give credit to junits15.

What you need:

water bottle with cap
aluminum can or other metals you can cut
motor (one that spins fast?)
tubing (copper or other source...)
wire
plexiglas
power source (3 - 9 volts)

Tools:

hot glue gun
scissors
hacksaw
drill

Step 1: Prepare the bottle cap

We only need the neck of the bottle. Cut the bottle near the top and sand it down.

Drill a hole in the middle of the bottle cap making sure its centered about the same size of the middle of the motor so it fits in. Drill a hole in the side big enough for the tubing going out. Don't forget to drill a hole in the bottle cap so the tubing can flow out.

Step 2: Motor and impeller

To make the impeller cut a strip of medal about 2 1/2 in. The height of your strip should be a little lower than height of your bottle cap/neck. Then fold your piece of metal in halve, then bend it at a 90 degrees angle where your motor is going to be. Bend all the sides until you have a plus sign.

Hot Glue your motor onto the bottle cap and make sure it spins by hooking it up to a power supply. (It doesn't need to be water proof...) If you haven't screwed the neck off yet do so now. (It'll make things a lot easier.) Hot glue your impeller to your motors shaft and let it cool. Screw your bottles neck back on and your done with this step..

Dude this was just what I needed

1. What is the exact location of the impeller ? Is it exactly alongside the side tube / outlet tube or above it or below it ? Does it churn the water as one of its functions ?

2. How high should the side / outlet tube be from the bottom / inlet tube ?

This is exactly what I was looking for.

What are some substitutes for plexi glass?

Did you by any chance salvage that motor from a Playstation analog controller?

How do I waterproof the shaft/bearings of the motor to prevent the water running inside the motor?

i was just looking for that
its nice really good like it

is it water proof?

If you make everything airtight you wont have to submerge it in water. You might have to have no air bubbles in it to work well though.

no video showing an operation?
Anyway ... I will do to test, I need it to send air to an aquarium or simply form a water circulator for him.

(just to tell people who read this) IT IS NOT A SUBMERSIBLE PUMP!!!!!!!!! i learned the hard way... I made a pump like this on solidworks and had it printed out. I needed a pump for an aquarium. how does the rotor stay on the shaft of the motor.
XDleader555 (author)  sageserver4 years ago
This pump wont work unless its underwater. it will work under water just make sure your power supply isn't under water... the impeller or rotor stays on by hot glue or you can try soldering it on.
you can add a longer input hose, you just need mor water pressure the longer the hose...
Is your motor certified waterproof? Otherwise, you could damage your power supply and your body. You could probably use this as a non-submersible pump if you primed it beforehand.
XDleader555 (author)  mattthegamer4634 years ago
It wont work cuz water leaks out and makes a mess. but sealing the leaks would do. the power supply is low and wont do damage to your body..... i think....
Its all about current... if theres a path through your body, its dangerous. Seriously, be careful.
ONLY 9 VOLTS!!! DANGEROUS??? NOOOOOOOOOOOOOOOOOOOO
well lets say I had 9 volts with 20 amps, that is very dangerous, even more so if it is DC voltage.
Think: 9V x 20A = 180 WATTS = It`s impossible for this motor.

well i didn't mean using it to power the motor, it was just an example. :)
9 volts with millions of amps= DANGEROUS. i dont think that motor is water proof. To check if it is just let it run for like a day till the battries run out and you see that the motor wont turn nemore.
almost every motor is waterproof. all of the motors I have I've tested underwater and the only problem was that they slowed down a little bit when the water got inside them beacause water is more dense then air.
use JB weld to attach it to the motor, it makes for a nice strong bond.  Just remember to sand the parts beforehand to make for an even stronger bond.

 about how far can it shoot water vertically is you used a fast motor and a 9v battery?

zack247 razhang3 years ago
depends on how long the "output" tube is
zack2473 years ago
hey this works nice. and you can unsubmerge it if you add a piece of tubing that is a little longer to the top, i did and it still works. a little less effectively, but it works

cool.... must try it :D

Thanks for this! It's very cool. ;) I made one too. :) Pics and video are on http://jan.klementa.cz/mleko-cd-rom-mechanika-vodni-cerpadlo-d :)

how much can it pump??
tzaq934 years ago
i made this thing and works great!! anyone know any other simple and fun tutorial like this one? :D
arihant4 years ago
i guess water will go inside the motor through  inpeller!what can i do in that case?????
zack247 arihant4 years ago
you could put a sponge around the motor to absorb the water, it would take months to rust the motor
zack2474 years ago
thanks! just made it. i couldnt make the impeller, so i used a premade one instead.
zack247 zack2474 years ago
i just tested it, and i have to say it works great for a homemade pump! i completely covered mine in hot glue because i couldn't pinpoint the leak. i noticed the seal area of the cap was leaking, i think it was because the cap wouldn't go on tightly because i took it off after i drilled the hole. how did your seal hold up so well? can you show me more pics of yours?

less diameter tube for output than input will increase height of water that comes out. Big impeller and faster motor rotation will do the same.

 if the motor is submerged, it will not last for long
