Extrex® RV/RB
When it comes to manufacturing profiles and dealing with strainers, high requirements are placed on pumping consistency and extrusion lines. The new gear pump series extrex⁶ RV/RB from MAAG raises the performance of gear pumps for elastomer extrusion to new levels in terms of both economy and processing technology. Product quality is guaranteed by a stable discharge, the lowest tolerance deviations and achieving process stability in quick time.

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.
The PC automation system is particularly suitable for stand alone or retrofitting of gear pumps in extrusion lines. Operation, control, regulation and monitoring of the operating parameters are simplified. Production data are displayed transparently and operation is simple and intuitive. Process and production safety of the line are increased.
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.
Support cart - Support cart for multifunctional applications
Together with the extrex6 we can also provide the support cart as a package. The new multifunctional support cart can be mounted in 2 different directions and is also adjustable in the height.
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.
The PFC automation system modular confi gurable solution for integrating melt pumps and
screen changer into complex extrusion process.
Operation, control, regulation and adjustment of the operating parameters. This guarantees optimum protection and operation of
the gear pump and screen changer. Process and operational reliability of the entire system is increased.
Twin outlet gear pump for complex extrusion applications
The extrex⁶ Y-Adaptor unites two extrex x⁶ class gear pumps to ensure optimum efficiency and cost-effectiveness in extrusion systems.
