Product Description:

The G series metering pump, also known as the MACROY® pump, is an ideal pump for water treatment applications.  It is capable of handling pressures up to 175 psi (12 bar) and flow rates up to 310 gph (1181 l/h).  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.


The G-Series or MACROY metering 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.
