How to DIY a 100% Waterproof Water Pump Using 3D Printer (non-contact magnetic coupling type)
Water pump always has a leak issue when long time use. It is caused by not completely sealed the rotation parts with the motor part. I designed this model that separates the motor from the impeller chamber completely. It is 100% waterproof since the rotation part is separated from the motor part. Use a strong magnetic coupling method this water pump can be used in very strict conditions for a long time.
I like to use a 3D printer to make some new and useful things. I also like to do some detailed systematic testing. At the same time, I will share the results with you, so that you can focus on useful things that interest you. This can take your work to the next level. You can also learn a lot of new knowledge and technique.
This is not the first attempt, but I think it is a good example of getting new ideas. I hope someone can get some new ideas from the smallest things. In addition, I hope they can share their experience with us and make the world a better place.
