Triton 3:1 150 SeriesAir-Operated Double Diaphragm Pumps

More suction power than a standard diaphragm pump to handle higher viscosity materials

Where to BuyRequest Info

Triton 3:1 150 Series double diaphragm pump provides extra power, longer pump life and superior finish quality.

  • 30% more suction power than a standard diaphragm pump to handle higher viscosity materials
  • Rugged stainless steel or aluminum construction requires less maintenance than a plastic pump
  • Twice the output per stroke
  • High output per stroke means less pump wear
  • Low pulsation output provides smooth pump changeover
