The G series metering pump, also known as the MACROY® pump, is now NSF/ANSI 61 and 372 certified for municipal compliance and safety assurance.  Capable of handling pressures up to 175 psi (12 bar) and flow rates up to 310 gph (1181 l/h) it is an ideal pump for water treatment applications.  Combining heavy-duty industrial drive technology with state-of-the art design and manufacturing processes, this mechanically-actuated diaphragm pump eliminates flow restrictions, reduces the possibility of hydraulic oil contamination of process liquid, and ensures smooth output.
