As the pump works under the same mechanism as a syringe, finer mist can be produced by increasing the inner pressure or changing the nozzle type. Depending on the viscosity of the contents, there are limitations to the inner pressure.
Additionally, when increasing the pressure in the tank within the pump, the spray load increases (in this case, consumers usually feel heavy action) and the tank wall has to be thicker. This is why there are limitations to the increase of the inner pressure.
Generally, finer mist is made by changing the nozzle type without increasing the inner pressure too much. We have various nozzles and you can evaluate our nozzles by yourself whether they make mist fine enough for you. Please let us know the details of your planned product and required spray particle size. We will suggest a solution.
We would like to have finer mist.
