MAAG introduces the vacorex®-x⁶ class gear pump. vacorex⁶ fulfills ideally modern polymer production processes which require pumps that can discharge at high pressure despite very low fill level and high vacuum conditions in the reactor/devolatilization vessel.
MAAG vacorex⁶ process a wide range of different polymer grades without affecting their quality. Reliable, requiring little maintenance, and robust enough to withstand the rigors of years of operation is vacorex⁶ gear pump the ideal solution for such applications.
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.

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.
Seal for polymer gear pumps and polymer pump systems and applications
High reliability and functionality are crucial for a seal in the polymer application discharging process for guaranteeing optimized product quality and line availability. The vispac® shaft seal is known for its robustness and reliability and especially for its easy handling. This low-maintenance seal is a proven combination of the viscoseal system and sealed packing glands for polymer pump systems.
