COMPRESSED AIR DIAPHRAGM PUMPS

Rain for Rent‘s Compressed Air Diaphragm Pumps offer high reliability, low air consumption and maximum performance. They are available
in three different versions: stainless steel, polypropylene or aluminium. The technically advanced pumps have smooth, reproducible flow properties, even for difficult jobs. A fast-acting, non-clogging air control valve eliminates air waste. All of the compressed air is used to move the liquid, reducing the total compressed air consumption for a given flow rate and therefore reducing energy costs. The ATEX air-operated diaphragm pumps are used in a wide range of industrial applications and projects where liquids up to 34 m³/h need to be pumped.

FEATURES & BENEFITS

  • High resistance to many chemicals
  • Zone 1 (gas) ATEX tested
  • Easy transport thanks to mobile frame
  • Dead center-free control valve
  • Easy installation and operation
  • Maintenance
  • Self-priming and dry-running proof
  • Oil-free air for environmentally friendly operation

EXAMPLES

Projects that require the pumping of liquids up to 34 m³/h. Possible applications in many industrial applications that require high demands on flow rate and safety:

  • Conveying liquids at high temperatures
  • Conveying liquids of high viscosity, e.g. sludge
  • Conveying aggressive and corrosive chemicals
