MAAG Gear Pumps Polymer Extraction and Transfer Pumps for Polymer Applications - VISCOREX VR

Polymer processing in the polymer industry requires systems for the gentle discharge of low-viscosity and 

high-viscosity plastic melts from reactors and vacuum degassing systems. MAAG polymer extraction pump 

systems and VISCOREX transfer gear pumps, with their excellent filling performance and short residence times, 

are the ideal solution for these polymer applications. Higher efficiency and a longer service life increase the 

capacity and utilization of polymer production lines. VISCOREX transfer gear pumps efficiently convey plastic 

melts at a constant, precise flow rate.
