Rubber melt gear pumps play a critical role in rubber production, particularly in melt extrusion and conveying. Their structural features include integrated cooling channels, specialized lubrication channels, and optimized flow path design to enhance conveying efficiency.
The use of wear-resistant bearings and shaft-end cooling technology enhances load capacity and process safety. Performance advantages include stable, pressurized delivery of high-viscosity materials, low shear stress, and high efficiency. Suitable for Mooney viscosities ≤120, operating temperatures ≤130°C, and outlet pressures ≤50 MPa, these pumps are widely used in polymer extrusion systems.
Rubber melt gear pumps find extensive application in the rubber industry, primarily within production processes—particularly for extruding and conveying rubber melts. Typically installed between the extruder outlet and die head, they function as melt metering pumps. Key characteristics include:
Materials and Processes Rubber melt gear pumps utilize wear-resistant bearings, enhancing load capacity and thereby increasing the pressure differential during conveyance. They also incorporate shaft end cooling technology, improving process safety. The application of dynamic lubrication enhances tolerance to contaminants, ensuring extended uptime.
Performance Advantages
The rubber melt gear pump delivers stable pressure-boosted conveyance of high-viscosity materials like rubber. Its optimized gear design achieves low melt shear stress under high pressure during conveyance and pressurization. Even at elevated discharge pressures, rubber melt flows with consistent, precise volume.
