In fact, the Roy G/MACROY series is an ideal choice for water treatment applications. They can handle pressures up to 175 psi (12 bar) and flow rates up to 310 gph (1181 l/h), and are now NSF/ANSI 61 and 372 certified.
The Milton Roy G Series/MACROY series dosing pumps are perfect for chemical dosing in water and waste treatment facilities, industrial process, agriculture, and many more applications. These pumps reliably inject chemicals such as ferric chloride, aluminum sulfate, polymers, alkalis, sodium hydroxide, acids, anti-scaling and anti-foaming agents and many more for coagulation/flocculation, slurry treatment, pH control and adjustment, and desalination.
