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 chemical feeding.
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.
The use of the multi voltage circuit design allows the pump to work anywhere in the world.
A wide variation
In addition to the standard type of PVC, GFRPP, PVDF or SUS316 pump head, B- or C-type drive unit and each diaphragm size, the high compression type for gaseous liquid transfer (sodium hypochlorite, etc), the high pressure type for power injection (boiler compounds, etc) and the high viscosity type for viscous liquid transfer (polymer liquid. etc) are available.
The EWN-R has the mode of 1:1 operation, multiplier/divider programming control (digital signal) and proportional control (analogue signal) and can dedicate itself to a particular purpose by selecting a suitable mode. Also, the flow rate indication can be converted from spm to L/H or GPH.
The use of the integrated controller reduces a sealing area, so that the water-/dust-proof design of IP65 is attained. Also, a plastic cover protects the control panel under an adverse environment.
Air vent valve
Rotating a standard air vent valve, the remained gas can be easily expelled from the pump head.
Multi hose connection
The use of a new hose stopper eliminates a twist in tube connection.
