GMB booster gear pumps are used in the polymerization process to increase the pressure of medium to high viscous media. The hydraulically heated booster pump transports prepolymers and polymers, such as PET, PBT, PS, ABS and many others, in a very gentle manner. The heating is done through heat transfer oil or steam.

The GMD series are discharge pumps designed to gently extract low to medium viscosity melts from reactors or tanks. To meet the requirements of low-viscous polymers, the GMD pump is equipped with a sophisticated sealing system that prevents leakages, even under difficult processing conditions.
