The reliable transfer and booster gear pump for polymer processing
BOOSTER polymer processing pumps are used in the polymerisation process, to boost the pressure of medium to high viscosity media. They transport pre-polymers and polymers, e.g. PET, PBT, PS, ABS any many more, very gently Heating is either by way of heat transfer oil or steam.
The core components like shafts and friction bearings originate from the WITTE building block system.
