Abstract
Plastics recovery and polyolefins compounding systems utilize a gear pump for the pumping function. The gear pump is specially designed to include a free media surrounding substantially the entire gear face with minimum sealing to improve volumetric pump efficiencies and provide pumping capacity insensitivity to viscosity over a wide range. A method of monitoring melt index and production rate for reactor control is also disclosed.
