Ran air-operated double-diaphragm pumps are known for their affordability and reliability.
Gisan Machine Co. is one of the few pump companies that manufacture its own pump diaphragms, check valves, seats etc. As a result they have more control over the quality of these components and can supply at more competitive prices. In particular, they are unique in that they have mastered the difficult process of moulding PTFE diaphragms.
All their diaphragms and components are made from the highest quality raw materials sourced from world class suppliers.
Ran aodd pumps are non-stalling and have the following capabilities:

  • Handles a wide variety of fluids with high solids content
  • Self-priming up to 6 m
  • Ability to run dry without damage
  • Variable flowrate and discharge pressure by simply regulating the air supply
  • Portable and simple installation
  • Dead heads against closed discharge
  • Pump shear sensitive fluids e.g. latex
  • Explosion proof, they are intrinsically safe
  • Sealless: no mechanical seals or packing to leak

Operating Limits:

  • Flow up to 55.8 m³/h
  • Head up to 16 bars
  • Max solids handling: 9.5 mm
  • Max temperature: 105° (metallic body) and 60°C (plastic body)
  • Max suction lift: 6 m
