Why Choose the CX-GWMP-12?

The CX-GWMP-12 gear metering pump is engineered to handle highly viscous, filled silicone rubber with exceptional precision. Its robust construction withstands high outlet pressures up to 8 MPa and temperatures approaching 200°C, making it ideal for vulcanization processes requiring consistent volumetric output.

With a displacement of 12 CC per revolution and superior material compatibility, this pump ensures uniform flow and reliable metering—even when processing abrasive fillers such as aluminum hydroxide and fumed silica with particle sizes below 25 microns.

Typical Applications

• Silicone rubber vulcanization lines

• High-viscosity fluid metering

• Filled polymer processing

• Precision dosing in demanding industrial environments
