Polymer processes require pumps that gently process both high and low viscosity plastic melt through the system.
Specially designed low-compression teeth allow the thermorex®-x⁶ class transfer, booster or metering gear pump to achieve both high pressure and low shear. The plastic melt is conveyed with a constant, precise flow even at high discharge pressures — and this also for low viscosity products like prepolymers, where former pump generations reached their limits. Additionally, their high efficiency and long service life will enhance the capacity of any given production plant.
Suitable for Resin & Virgin Polymer Production
Configure your own product according to your requirements and needs. If you are unsure of the configuration, provide us in the notes the necessary information about the existing sensor or product, even a competitor. We will be happy to help you find an alternative MAAG products. If your request is urgent, let us know. We will do our best to help you resolve this situation to your satisfaction as quickly as possible. If we have all the information, we are able to offer a model with minor differences.

Seal with buffer fluid for chemical pumps and chemical transfer pumps in industrial applications
The Double Mechanical Seal is a MAAG brand for industrial application and chemical pumps. It has a robust design with buffer fluid. Therefore, it is suitable for corrosive and abrasive applications. The sealing rings are available in carbon and SSiC (sintered silicon carbide ceramic) for chemical transfer pumps.
Together with the extrex6 we can also provide the drive unit as a package. For optimum performance it is important the drive units are calculated to the application requirements and as accurately as possible. Maag has both the experts and high level modeling programs to assure just the right combination of torque, speed and efficiency.
Newly introduced is our Dual Drive unit designed for high abrasive, recycling and Fluoro polymer applications. The Dual drive unit is a Maag own development to bring up an economical and effective solution for processes requiring minimum gear toothand loading.
Packing glands in various executions for polymer gear pumps and chemical pumps. Without adaptions to modern sealing technology, these components are no longer widely used. Packing glands are available in a buffered model for polymer applications.
ViscosealAvailable for high viscous fluids
The viscoseals are available for highly viscous fluids which are used for extrusion gear pump systems. The seal is contactless and dynamic. It has a simple design and has only one sealing part. A cooled model is available for the polymer extrusion industry is available and it is virtually maintenance free.
