High pressure pumps for UAV spraying

Hello everyone,

There is a need for a light high pressure pump for UAV spraying, what is out there in the market has not been designed for this application and are heavy and bulky, so I was thinking about the possibility of using a low Kv outrunner motor for this high torque application, here is a design I found:


If anyone here has any input, it would be greatly appreciated.

  • Looks like a good design. I also sent you a PM.

  • Well its all about the performance/weight, the more power, the more efficient the spraying would be as it would cover more area so less flying time and more area gets covered..
    That is the purpose of it
    • Designing an impeller pump that can be attached to a brushless motor seems like a great idea.

  • Do you really need high pressure?
