extrex6 ER

Booster pump for the elastomeric processing industry

Elastomeric processing requires positive displacement devices that gentle convey high viscosity rubber through the system. Specifically designed, low compression tooth design allow the extrex6 ER transfer, booster or metering gear pump to achieve both high pressure and low shear. The rubber compound is conveyed with a constant, precise flow even at high discharge pressures – and this also for extremely dry or sticky compounds, where former pump generations reached their limits due to scorch. Additionally, their anyway high efficiency and long life span will extend unrivaled due to reduced internal friction.
