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