extrex⁶ GU

General Use gear pump for thermoplastic applications

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.

The extrex⁶ GU gear pump is a general use design that elevates your process to the next level. With the new x⁶ class design you have additional benefi ts 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).
