Super Pressure gear pump solution for thermoplastic applications

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.
