OP242CD (2:1 ratio)

Air Operated Fluid Pump which is specially designed for corrosive materials. Commonly used for low ceiling applications.


  • Fully air operated
  • 2 ball piston design provides uniform positive displacement
  • Extremely durable pump with long life packing
  • Specially designed piston seals do not come into contact with material pumped. Hence, a longer life span as it is able to handle highly problematic fluids like Isocyanates which crystallizes on piston rods upon contact with moisture in air and rupture seals.

Typical Applications

  • For 55 gallons steel drum
  • This pump is designed for the convenience of operator to take out/shaft in the pump when working inside the truck, due to smaller diameter at the bottom of the pump
  • For fluid transfer and feed
  • Mobile air spray machines

Typical Fluids Handled

  • Polyurethanes (Isocyanate or Polyol)
  • All kinds of paints
  • Coatings
  • Mold release
  • Stains
  • Varnishes
  • Lacqueurs
  • Lubricants
  • Water
