viscorex VR

Discharge gear pump for polymer production

Manufacturer: MAAG
Category: For polymer production

viscorex VR is a transfer gear pump for the gentle discharge of low- and high-viscosity polymer melts from reactors and devolatilizers. It stands out for excellent filling and short residence time and conveys the melt at a constant, precise flow rate.

Benefits

Excellent filling thanks to optimized inlet geometry
Optimized flow channels
Gentle handling of the polymer melt thanks to special low-compression gearing
High overall efficiency and thus minimized friction thanks to pioneering gearing and bearing technology
Low-pulsation pumping even at high differential pressures
Compact design

Applications:

Virgin polymer production
