Elastomer Extrusion Pumps

Extrusion gear pump for elastomers and rubber manufacturing with highest performance – extrex® RV/RB

Extrex⁶ ER

Elastomeric processing requires positive displacement devices that gently convey high viscosity rubber through the system. The specific low-compression tooth design of the extrex⁶ ER extrusion gear pump enables transfer, booster, or metering gear pump applications to achieve both high pressure and low shear.

The rubber compound is conveyed with a constant, precise flow even at high discharge pressures – also for extremely dry or sticky compounds, where previous extrusion pump generations reached their limits due to scorch. Additionally, the constant high efficiency and long life span of the extrex⁶ ER extrusion gear pump are improved even more owing to reduced internal friction and achieve unrivaled high values.
