The ParaDyne liquid polymer activation system from IPM Systems includes a polymer check spring located outside the path of polymer flow to eliminate the polymer from gumming or clogging around the spring. A non-impinging rotor is used to pull polymer through the mixing zone to provide efficiency and eliminate damage to the polymer. There is no need to recirculate the polymer solution through the mixing zone, eliminating the possibility of partially hydrated polymer molecules. The chamber has a flushing valve for the mechanical seal pocket to extend the life of the seal. The standard unit is able to handle 20 gpm through the chamber. An optional post dilution line can be used to provide an additional 20 gpm. 855/328-9200; www.ipm-sys.com.
