Multi voltage, High-speed operation, Multifunctional controller The high-end electromagnetic metering pump GFRPP type PVDF type The EWN-R is the diaphragm type electromagnetic metering pump with a built-in multifunctional digital controller. Our technology makes the high-speed operation of 360spm available. The built-in controller that handles both digital and analogue signals controls operation in various ways. PVC, GFRPP, PVDF or SUS316 pump head is selectable. Also, special pump types for particular purposes are lined up. The user-friendly EWN-R will meet a wide variety of demands for...

IWAKI ELECTROMAGNETIC METERING PUMPS High resolution The stroke rate can be set with 1spm increments in between 1 and 360spm. The stroke length adjustment further assists fine adjustment that the stroke rate adjustment cannot reach. Contentious precise chemical feeding is now available. Rotating a standard air vent valve, the remained gas can be easily expelled from the pump head. Multi voltage The use of the multi voltage circuit design allows the pump to work anywhere in the world. Multi hose connection In addition to the standard type of PVC, GFRPP, PVDF or SUS316 pump head, B- or C-type...
