pressing order
1.Air piston pump adopts the theory that "pressure" applying force on various areas and can produce various "acting force", the pump takes the origin that the compressed air is compressed energy, and transforms the pressure of compressed air into more fluid pressure, pressing fluid move in order to achieve the aim of high viscosity and ultra-viscosity fluid.
