We extrude fluoropolymers and would like to decrease the amount of set-up time and material. Melt pumps will add to your setup time. I have found that a melt pump is a bandaide for a poor process, most usually poorly designed screw, poor drive (like using a DC drive geared for 100 RPM at 5 RPM), or poorly maintained equipment. I have worked with close tolerance FEP tubing over the years, and have never had to use a gear pump (down to 28 gauge). IP: Logged
