Neptune Chemical Pump Co. Inc. has introduced a new explosion-proof polymer makedown system for preparation, activation and injection of liquid polymers in water and wastewater treatment applications. The system can produce dilute solution (0.1%-2.0%) at capacities from 20GPH to 3000GPH of total makedown solution. Neptune’s explosion-proof polymer makedown system features all stainless steel construction. This new polymer makedown system uses the patented “Gatlin Mixer” for mechanical mixing and blending of polymer material. The Gatlin is a motorized mixing chamber that segments the polymer into ultra-thin film for maximum activation. There’s no need for booster pumps, and materials are mixed and blended without blades to damage fragile polymer chains. The Gatlin system is unique in that it maintains maximum activation regardless of fluctuating flow rate or water pressure. An interlock prevents polymer feed if water flow is insufficient. Standard systems include manual or automatic electronic metering pumps for polymer injection; larger models use motor-driven metering pumps or progressing cavity pumps. Available accessories include a desiccant breather, a calibration column kit and a drum mixer.
