External-gear pump DuroTec® DT

for chemicalsindustrialtransfer

DuroTec® Gear Pumps DT for abrasive and poor lubricating fluids. The limit of applications of Gear Pumps has been reached when the transfer medium does not have the required lubricity for a proper function of the pump and a high working pressure is needed at the same time. Such problematic fluids are for example silicates (sodium silicate), isocyanates and polyols with hard fillers as can be found in the PUR-technology. Under air or humidity influence, crystallisation of these fluids occurs and agrivates the lack of lubricity. The gear (gear wheel and shafts) is surrounded by SIC bearing bush. The gear is high-rigid protected against wear, taken the requirements regarding material, heat treatment, surface geometry into consideration when using this coating technology. Highest demands have been fulfilled by our own manufacturing quality and the involved coating specialists. polyols with hard fillers as can be found in the PUR-technology.
