Melt pumps are primarily used for conveying, metering, and pressurizing high-viscosity melts. They are widely applied in polymer production fields such as chemicals, plastics, and synthetic fibers. Key applications include:
1. Precise Conveyance and Metering
In production processes like polymerization, pelletizing, and film extrusion, melt pumps deliver high-temperature molten materials (e.g., polymer melts) at a stable flow rate to subsequent stages. This ensures continuous production and precise control over material flow.
2. Pressure Boosting and Stabilization
As positive displacement pumps, melt pumps deliver a fixed volume per revolution. This creates stable pressure, minimizing quality issues like uneven product thickness and surface defects caused by pressure fluctuations in subsequent processing stages.
3. Ensuring Product Quality and Enhancing Production Efficiency
Melt pumps integrate with extruders to reduce screw pressure requirements, lessen extruder load, and lower costs while improving efficiency.
Common Applications:
Plastics Processing: Extrusion molding of films, sheets, and pipes;
Chemical Fiber Production: Melt conveyance in spinning processes for polyester, nylon, etc.;
Rubber Industry: Extrusion calendering of rubber compounds;
Chemical Polymerization: Pressurized melt conveyance after reactor discharge.
