Available in two motor driven models – the SD and the SG – the Series G Metering Pumps feature rugged aluminum construction specifically engineered to handle higher output applications in harsh environments. Certified with NSF / ANSI 61 and 372 for municipal compliance and safety assurance, the Series G is the right choice when choosing a pump for water treatment applications, like coagulation and flocculation. By combining a heavy-duty industrial drive with state-of-the-art design, the Series G offers a mechanicallyactuated diaphragm that provides smooth output with reduced potential for system shock and hydraulic oilcontamination.
