PULSAblend polymer makedown systems from Pulsafeeder are available in three control options — automatic, manual or dry contact. All systems have a three-step static blending system that provides dilution without harming the polymer chains. With a wide range of dilution using three different water flow rates to choose from (0 to 5, 5 to 10, and 10+ gpm), the system is custom sized to provide activation of all types of polymers, without the sometimes damaging effects of motorized mixing devices. Five polymer pump flow rates ensure the right makedown for any application. Systems include an auto-fill calibration column, an adjustable flowmeter and a polymer back pressure regulator to maintain a consistent, repeatable final product. 800/333-6677; www.pulsatron.com.
