MELT GEAR PUMP

Melt pumps are volumetric pumps which meter polymer through a set of intermeshing gears. It can be used as feeding and metering.

WORKING PRINCIPLE

The processing industry is indeed under increasing pressure to evolve towards more sustainable and efficient practices. Process intensification, cleaner production, and continuous optimization are key strategies that address these challenges by aiming to make industrial processes more effective and environmentally friendly.

MAIN DESIGN FEATURES

Effective self-cleaning to minimize dead zones, product accumulation and product degradation
