Diaphragm Pumps Ltd

Dellmeco Air Operated Double Diaphragm (AODD) Pumps are becoming the most common pumps for use when Only Air is available or when pumping solid laden liquids or slurries. Dellmeco Diaphragm Pumps have no seals as the diaphragm acts as the barrier between the Liquid side and the drive side of the pump. When the liquid pressure reaches the air pressure, the Dellmeco pump reaches a point of balance and stalls without the need for bypasses or overload protection.Dellmeco Diaphragm Pumps pump can run dry indefinately and have the ability to self prime to 7 metres or more in some cases. They can handle viscosities up to 20000 Centipoise as standard and some Dellmeco models can handle cPs into the 100's of 1000's. Dellmeco Pumps are some of the most reliable AOD's in the marketplace, Self Priming, Dry running, Intrinsically safe, these are just a few of the features of Dellmeco Diaphragm Pumps. Models include pumps for pumping hygienic products, aggressive chemicals aswell as standard industrial duties. High pressure models are also available for filter press applications or for pumping into closed systems. ATEX regulated Dellmeco pumps are offered for Zone 1 environments. Dellmeco Pumps and spares are available from Diaphragm Pumps Ltd, Stoke On Trent, England. As one of the largest stockists of pumps and spares in Europe, we hope we can supply all your Dellmeco Pump needs.

  • Seal less - are environmentally friendly, no seals or packing to leak
  • Safe in hazardous areas - air driven - non sparking
  • Can run dry without damage
  • Self-priming to over 8 meters
  • Variable flow - simply regulate the inlet air supply to adjust the pump flow from zero to max flow
