thermorex® TRO/TRP

Transfer pump for oligomers and prepolymers

Polymer processes and polymer applications require polymer transfer pumps which will constantly and reliably feed oligomers and prepolymers through the system. The liquid polymer pump design is highly suitable for low viscosity. Thanks to thermorex® TRP and TRO, reactors no longer have to be pressurized. The good efficiency and long service life increase the efficiency of your production plant with polymer transfer pumps from MAAG.
