The extrex⁶ SP gear pump is a high pressure gear pump for applications dictating high pressures and loads. With the new x⁶ class design you have additional benefits compared to the classic gear pump designs.
All Pumps are available with ST design (flow optimized) and with the 5R design (Retrofit flange design classic pump).
Extrusion operations require extremely reliable gear pump systems with high output consistency and a configuration to suit each application. The modular design of extrex® gear pumps easily meets the requirements for these diverse applications.
Suitable for Extrusion
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.
If you need more information do not hesitate to contact us.

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.
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.
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.
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.
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.
