    do you have distributor in USA?
    as far as i know, the diaphragm pump could offer constant Stable pressure , much better performance than piston pump, am i correct?
    so if i want to spray cabinet door or furniture , the diaphragm pump paint sprayer would be my 1st choice?

      Hi stanley,

      We got distributor in USA but not for the diaphragm pump.
      It’s ture that the diaphragm pump offer constant Stable pressure, and it doesn’t mean it will be suitable for the cabinet door or furniture, actually the airless system with high pressure won’t be your 1st choice.

      You may need the air-assit airless with low pressure for fine finish, such as the DP-637G40 gun.
      And the whole system will be more expensive than the airless. and mainly be used in factory for large volume spraying.

      For the small project or hobby use, the traditional air spray gun should be your 1st choice then.

      Please feel free to contact us if any questions
