Hot melt adhesive melt pump is the core metering and conveying equipment specially designed for hot melt adhesive systems. It steadily transports high-temperature molten hot melt adhesive from melter or extruder to coating, laminating and other finishing processes, guaranteeing continuous, uniform production and consistent finished product quality.
Key Benefits
Precise Flow Control
As a positive displacement pump, its output flow has a linear relationship with rotating speed. The metering error can be controlled within ±1%. It effectively prevents uneven glue coating and raw material waste.
Stable Pressure Output
The hot melt gear melt pump greatly reduces pressure fluctuation during glue delivery. Constant pressure ensures uniform coating thickness and improves finished product qualification rate.
Wide Material & Temperature Compatibility
Working temperature range: 150℃ – 250℃. Compatible with EVA, PU, PA and other common hot melt adhesives, suitable for multiple industrial production scenarios.
