The Series G Metering Pump is designed for high output applications. Water treatment chemicals, process additives, acids, out-gassing fluids, slurries, and many more applications are all handled with ease by this robust metering pump design. The drive incorporates a variable eccentric design which ensures smooth output and reduces system shock. The mechanically actuated diaphragm reduces the possibility of hydraulic oil contamination of process liquid which makes this an ideal pump for water treatment applications. DC variable speed drives are available for external control and automation.
