About this 3D model

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. https://youtu.be/BdqtM83uNWY
