The Air Operated Double Diaphragm Pump from Sotera Systems is a positive displacement pump with two diaphragms and a ceramic air valve. Sotera is the most efficient air operated diaphragm pump on the market, providing the highest flow in the industry, as well as the lowest pulsation and leak-free operation.

Ideal for a variety of tasks and circumstances, the Air Operated Diaphragm Pump is suitable for:

  • Pumping liquids with considerable amount of solid particles (concrete, cement, agricultural, chemicals, china clay)
  • Pumping abrasive liquids (sludge, slurries, waste)
  • Pumping viscous fluids (paint, resins, rubber, oil and lubes)
  • Emptying a vessel (drum, barrel, sump) and placing a pump in an awkward place including inside the vessel itself
  • Pollution-free operation with no oil consumed and no oil mist vented by the oil free compressor operating the pump

With the highest flow rate in the industry at 17.5gpm and the lowest pulsation, the Air Operated Diaphragm Pump offers quickly and efficient transfer of fluid without the splash and mess. Patented Air Valve design provides the low pulsation (low pressure drop) and the patented ring construction provides the lowest turnaround time in maintenance.

The Air Operated Double Diaphragm Pump is the most advanced pump on the market, offering the following features:

  • 66% reduction in pulsation and 15% higher flow rate thanks to a fast tip-over of ceramic air valve
  • 67% fewer parts and 50% less time to repair
  • Long lasting diaphragm construction for consistent performance and longer operating life
  • Made in the USA with 5 years warranty

The Air Operated Double Diaphragm Pump is fast and offers user-friendly maintenance together with rugged construction and reliability

  • Simple, with very few moving parts and wear-prone components
  • Easy to maintain and service
  • Minimal machine downtime for increased productivity
  • ½”, 1” models are available with a 2” model expected soon

The SP100 Series Air-Operated Double Diaphragm Pump can be configured in materials that are resistant to industrial chemicals and proven to provide complete compatibility coverage for a wide range of fluids.

When choosing the pump, seek help from the experts to choose the most suitable diaphragm for your product/application. Correct sizing will also affect maintenance costs, and it may be economically viable to get a slightly bigger pump and run it at lower speed.
