Building a solar water pump ( including the motor)

Here is a project of mine.
I build a solar water pump wich will be low pressure but high volume per hour.
Im making it from somme old Dacia car alternator where i use only the coil and the housing.
The pump will be submersible and the coil will be sealed by a few layers of silicone.
The rotor i didnt made it iet but it will have neodymium magnets on it and the bearings i chosed somme really long lasting plastic( tephlon) and glass beads bearings.
The pump as i said will be submersible,the motor brushless,will work at 18- ( maybe )5 V.
The controller of the pump is a chinese 30 Amp controler for brushless motors .
Im aiming at a flow of 10 cubic meter per hour at 100Watts power consumption .
This pump will recirculate the water in my trout pond during the day through a 10 cm (5in) wide pipe .

interesting project.

I don't see impellers, the blades which push the water.  does your pump work without impeller blades?  

could you include a simple drawing for the pump you are building?   maybe show how the pump will fit inside or attach to the pipe?   ....or maybe mockup with the items you have to show us how you've intended it to work?

On your request i made a sketch of the pump and the solar pannels.
The impeller will probably be a simple bend stainless steel blade or something verry rudimentary in any case and only the impeller will be mounted directly into the pipe.

Nice! makes it easy to see what you've designed....should work fine as you've described it
