Headline

EZ Series

EZ Series electronic metering pumps offer precise chemicalinjection at a low cost. The compact size and simple controlmake them ideal for water treatment and OEM applications.EZ Series have outputs to 6.3 GPH (24 l/h) and a maximumpressure of 150 PSI (10 bar). Advanced microprocessorcontrol and a turndown ratio of 360:1 make this series anexceptional value. The pumps are simple to operate withonly three pushbutton keys and the unmatched turndownratio provides both versatility and high resolution chemicalfeed which eliminates slug-feeding effects.
