  • No rotating parts：Avoid splashing of chemical liquids
  • Inherently explosion-proof  ： No electronic components, highly safe in chemical environments
  • Self protecting：Automatically shuts down when the outlet is blocked
  • Dry running capability：The pump can operate without liquid without damage. 
  • Strong suction power：No need to pilot water (suction lift up to 5m)
  • Good through-pass performance：conveying liquids with high viscosity, particles.
  • Adjustable flow rate：flow rate can be adjusted easily via air source(between 0.1~0.84 MPa).
  • Simple structure with low maintenance costs：Parts can be replaced quickly and conveniently.
Our Advantages
 

Highlights

  •  High-end imported diaphragm
  •  Low friction pump shaft
     Patent air valve cover
     Pilot type air motor
     large volume flow chamber
     Integrated diaphragm block
     High quality hardware
     Three port design
     

Better sealing and ball life

- The ball is twice grinded by professional machine

- Half-arc ball chamber design

- Reversible and reusable Valve seat
 
Thus assuring better sealing and ball life, reducing maintenance costs.
Large volume flow chamber
- The inner and outer surfaces of are hardened to make the fluid flow smoothly.
- The pump shaft has been grinded and hardened for low friction, high wear and corrosion resistance.
- The diaphragm block is integrated to avoid leakage.
High quality hardware
- Outer hexagon all stainless steel with flange screws, better stability than the inner hexagon screws.
