Gear pump for abrasive liquid
150 - 250 cm³/r, max 100 bar | DuroTec® DT 5 series
KRACHT
In the year 1990, KRACHT initiated the development of Gear Pumps for abrasive and poor lubricating fluids. Since then, this development has been subsequently improved. 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 operating 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 sleeve bearing. 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
