External gear pump can be used for most all thermoplastics: nylons, polyolefins, polystyrene, etc. It is not used for PVC due to its degradation characteristics. This may be resolved by formulating with more or different lubricants or more stabilizer, or both, but those things raise material costs and may take away from the economic justification for using the pump in the first place. Pumps have been made with other lubrication systems, but before using one with PVC details about what was the material and speed (as faster = less residence time = less degradation) must be sought, and get a trial if possible with the formulation that would be used with the melt pump for reactor in chemical industry.
