HygienicDiaphragm Pumps

Air Operated Hygienic DiaphragmPumps
POLISHED STAINLESS STEEL SIS 2343

This series of Dominator pumps is manufactured inSweden and has been designed to meet the strict hygienicrequirements of the food and pharmaceutical industry.

The inlet and outlet pipes are equipped with clamp bands and wingnuts for rapid disassembly, cleaning and reassembly.

All wetted parts are in polished stainless steel SIS 2343 and thenon-wetted parts in chem-nickled aluminum. Diaphragms and valveballs are available in various materials.

The pumps are equipped with dairy connections according to SMS, DINor 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 theyare equipped with suitable diaphragms and valve balls.

The discharge capacity is proportional to the stroking speed andcan be infinitely varied from 0-100 % by regulating the compressedair supply with a pressure regulator, or with a valve on thedischarge pipe.

The pumps are equipped with our patented air valve system. Withthis unique valve there is no risk that the valve will stall in thecentricity, and cause production break-down.

  Performance curves. For pumps type P3 fitted with teflon diaphragms reduce waterdischarge figures by 15 %.
NOTE: Max temperature may, a short time,during cleaning phase reach +130 oC, providing that thepump is equipped with diaphragms and valve balls in EPDM. 
We recommend the use of an air regulator on the air supply. Thesepump types are also available with two inlets and two outlets, typeT, e.g. T18-SBT.
