Air Operated Double Diaphragm Pumps

Our aim is Customer Satisfaction, Through Quality Products & Prompt Services
Positive Displacement Pumps
  • No electrical motor - non sparking.
  • No mechanical seals or gland packing.
  • The pumps can run dry indefinitely without damage.
  • Safe for use in hazardous/explosive environments.
  • Variable flow - simply regulate the inlet air supply to adjust the pump flow from zero to max.
  • If discharge is clogged or closed pump stops immediately; no power consumed, no wear.
  • By opening discharge, flow starts automatically.
  • Self-priming from a dry start up to 6 meters without a foot valve.
  • Pressure up to 100 PSI (7 bar).
  • Operates submerged or with flooded suction.
  • No close fitting, sliding or rotating parts so can handle a wide range of fluids with high solid content.
  • Gentle non-shearing action.
  • Quick assembly and disassembly with split clamp bands.
  • Pumps are light weight and portable.
