Core Function and Application Advantages of Hot Melt Adhesive Melt Pumps

Hot melt adhesive melt pumps serve as the core equipment for conveying and metering hot melt adhesives. They are primarily used to reliably transport high-temperature molten adhesive from melting tanks or extruders to end processes such as coating and laminating.

Key Advantages of Hot Melt Adhesive Pumps

Precise Flow Rate: As a positive displacement pump, output flow is linearly correlated with rotational speed. Metering accuracy is maintained within ±1%, preventing uneven application or waste.

Stable Pressure: Effectively suppresses pressure fluctuations during adhesive transfer, ensuring consistent coating thickness and enhancing product quality.

Versatility: Withstands hot melt adhesive temperatures ranging from 150-250°C and is compatible with various adhesive materials including EVA, PU, and PA, meeting diverse industry requirements.
