Heatable corrosion-resistant chemical transfer gear pump

The use of prepolymer pumps

Polymer processes and polymer applications require polymer transfer pumps which will constantly and reliably feed oligomers and prepolymers through the system. The polymer pump design is well suited for low viscosity. Thanks to thermorex® TRP and TRO, reactors no longer have to be pressurized. The MAAG thermorex® TRO/TRP gear pump can be flanged directly as a transfer pump under the reactor or mounted in-line.

The high volumetric efficiency and long service life increase the efficiency of your production plant with polymer transfer pumps from MAAG.

Advantages of prepolymer pumps

  • Excellent fill behavior due to optimized inlet geometries
  • Optimized flow channels
  • Completely heated
  • High overall efficiency, minimized friction thanks to pioneering gear and bearing technology
  • Low pulsation pumping even at high differential pressures
  • Compact design
