Non-Metallic Construction 

Blagdon Air-Operated Double Diaphragm (AODD) Pumps provide high performance, reliable solutions for your pumping needs. They specialise in extreme condition environments and applications...keeping your process moving both above and below ground. Their AODD pumps have long been recognised as the "workhorse" of the industry for handling difficult liquids at relatively low pressures and flows. The range of applications is virtually limitless!
 
The pump chambers are alternately filled and emptied by drawing fluid in through a common (suction) inlet, and out through a common (discharge) outlet. The diaphragms in each chamber are linked by a common shaft so that they move backwards and forwards in unison. Compressed air is directed by the air valve alternatively, behind each diaphragm, to power discharge strokes. Pump speed, fluid output and pressure (or head) is controlled by increasing or decreasing the flow of compressed air to the pump.
 
Thomson Process Equipment & Engineering Ltd. supply Blagdon pumps into the markets of Ireland and Northern Ireland.
 

Common applications:

  • For corrosive liquids and chemicals
  • When metallic contact is not acceptable
  • Low cost, straight forward construction
  • When electrical power is not available
  • Noise sensitive areas
