Rubber melt gear pumps have widespread applications in the rubber industry, primarily used in the rubber production process, particularly for the extrusion and transportation of rubber melt. They are typically installed between the extruder outlet and the die head, serving as melt metering pumps.
The key features of rubber melt gear pumps are as follows:
1. Rubber melt gear pumps feature built-in cooling channels, enabling more precise and rapid temperature control. Additionally, they incorporate specially designed lubrication channels, making them highly suitable for rubber and elastomer materials. The channel design has been optimized to minimize dead zones and enhance conveying efficiency.
2. Materials and Processes: The rubber melt gear pump uses wear-resistant bearings, enhancing load capacity and increasing the pressure differential during conveying. It also employs shaft-end cooling technology to enhance process safety. The application of dynamic lubrication improves resistance to contaminants, ensuring reliable operational uptime.
3. Performance Advantages The rubber melt gear pump can stably pressurize and convey high-viscosity materials such as rubber. It optimizes gear design to achieve low shear stress on the melt under high pressure while conveying and pressurizing. Even under high discharge pressure, the rubber melt can be conveyed at a constant and precise flow rate.
Additionally, this melt pump reduces internal friction, resulting in unmatched high efficiency and long service life.
Rubber melt gear pump specifications: Mooney viscosity ≤120, operating temperature ≤130°C, cleaning temperature ≤350°C, discharge pressure ≤50 MPa. Features include a shaft seal spiral external heating system, thermal fluid heating and cooling system, and shaft end cooling system. Available in sizes from 50 cc to 2500 cc.
