spunbond machine 50cc extruder hot melt dosing pump

The 50cc extruder hot melt dosing pump is a vital component for spunbond nonwoven production lines, delivering unmatched precision and stability for high-viscosity polymer processing. As the core of spunbond machines, it ensures consistent melt delivery, directly boosting product quality and production efficiency across automotive, agriculture, medical, and other key industries.

Engineered for extreme working conditions, this 50cc model handles temperatures up to 400℃ (750℉) and viscosities reaching 40,000 Pa.s, compatible with PP, PET, PVC, PA, and other common polymers. Its low-pulsation design—powered by cam curve compensation an electronic suppression—eliminates flow fluctuations, guaranteeing uniform fiber formation in spunbond webs. Microprocessor control and multi-point calibration enable accurate dosing even at variable flow rates.

Constructed with high-temperature tool steel and nitrided gears, the pump offers exceptional durability and wear resistance, minimizing maintenance downtime. It features electric rod heating for consistent temperature distribution and spiral sealing for leak-proof operation. Compatibl with 220V/380V power supplies and supporting OEM/ODM customization, it seamlessly integrates with most spunbond extruders. For manufacturers, this pump reduces material waste, enhances line productivity, and supports 24/7 continuous operation, backed by a one-year warranty.
