Gear Pumps KP 1 DuroTec® DuroTec® Gear Pumps KP 1 Description DuroTec® gear pumps KP 1 for abrasive and poor lubricating fluids. The limit of applications of transfer 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 PU-technology. Under air or humidity influence, crystallisation of these fluids occurs and agrivates the lack of lubricity....
