Is the gear pump suitable for all extrusion processes?

From the technical point of view there is basically no extrusion process where the melt pump cannot be installed. It is commonly used in sheet extrusion (PET, PP, PE, PS, HIPS), compounding, pelletizing (strand and underwater), coating, pipe, profile, blown film and cast film extrusion. Melt pumps can also be found in the production of wires, cables, textiles (fibers, filament and non-woven), EVA, hot melt adhesives and PSA.
