NRG's NM720-CS Non-metalic Collector Chain is ideal for the harsh, unpredictable conditions found in sewage treatment plants. It is precision molded from glass reinforced polyester that resists elongation, wear and corrosion like no other thermoplastic.

During the injection molding process, the unique thin walled design of the chain mold ensures glass fiber alignment, keeping each link linearly strong and lightweight (1/5th the wt. of metal chain). Without any special tools, the NM720-CS chain can be easily assembled with a rubber mallet, as snap type T-head nylon pins fit snuggly in the barrel, preventing rotation and keeping grit out. NRG's NM720-CS chain lasts twice as long, is easier to maintain and install, and is much more energy efficient than metal 720 series chains. Available with our special "Grit Slayer" Teflon impregnated pins for tank conditions where sand and grit are prevalent.
