Dominator 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. Dominator 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 Dominator pump reaches a point of balance and stalls without the need for bypasses or overload protection.Dominator 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 Dominator models can handle cPs into the 100's of 1000's.

The inlet and outlet pipes are equipped with clamp bands and wing nuts for rapid disassembly, cleaning and reassembly.
All wetted parts are in polished stainless steel SIS 2343 and the non-wetted parts in chem-nickled aluminum. Diaphragms and valve balls are available in various materials.
The pumps are equipped with dairy connections according to SMS, DIN or Tri-clamp, except for the smallest pump which have ½” male threads or Tri-clamp.
The pumps can be sterilized by autoclave or “CIP”-cleaned up to +130°C, providing that they are equipped with suitable diaphragms and valve balls.
The discharge capacity is proportional to the stroking speed and can be infinitely varied from 0-100 % by regulating the compressed air supply with a pressure regulator, or with a valve on the discharge pipe.
The pumps are equipped with our patented air valve system. With this unique valve there is no risk that the valve will stall in the centricity, and cause production break-down.
