Key factors in all areas of the process industry are production reliability, productivity and performance. These are precisely the areas addressed by the DESMI range of products, systems and services. One of the distinguished features of the ROTAN® ED range is that they are magnetically coupled internal gear pumps specially designed for ultimate protection against leakage. ED pumps require minimal maintenance making them a very economical solution compared with traditionally sealed pumps,especially where the application requires the use of double mechanical shaft seals. Often these applications are very arduous resulting in the seals and support system requiring regular attention and/or replacement. Thus, the life cycle costs for ED pumps are generally much lower than for pumps using two seals. Additionally these pumps are available with 90° angular configuration.
ED pumps are available in Cast iron, carbon steel or stainless steel materials with capacity ranging up to 90 m3/h or 400 gpm and maximum running capacity of upto 1750 rpm. These pumps are designed to handle viscous of upto 10,000 cSt and temperature upto 250oC/500oF. The suction lift for ED pumps is set up to 0.5 bar or 15″ Hg vacuum while priming and up to 0.8 bar / 24″ Hg vacuum while pumping. The pumps are designed to handle differential pressure up to 16 bar / 250 psi. ED pumps are used in typical Applications where no leakage, liquid or gaseous, is allowed like for pumping of Isocyanate, Solvents, Hazardous organic liquids, Printing ink, Resin, Pitch, Alkyd resin, Soya bean oil, Linseed oil, Monomers, Polyol, and Corn syrup.
