PEP-II series gear pumps serve as a pressure booster/stabilizer on the discharge end of an extruder and for precise additive injection into the extruder barrel. Constructed of through-hardened, high-speed tool steels or 400-series stainless for corrosion and wear resistance.

PEP-II gear technology utilizes low-aspect-ratio crowned-root gears. With L/D ratio of 0.75 vs. industry standard of 1.0 for helical gears, PEP-II ensures polymers have less distance to travel, thereby reducing tooth pulsations. Crowned roots are parabolic-shaped undercuts, which offer less resistance to tooth evacuation flow and further tooth-pulse reduction. Company reports that the combination of crowned root and low-aspect ratio gearing provide superior extrusion performance, superior mechanical integrity, and greater efficiency than conventional designs.
