Iwaki's New EWN-Y Series Electromagnetic metering pump with the revolutionary EFS Flow Sensor provides precise flow monitoring, feedback and control.

The new EWN-Y electromagnetic pump combined with EFS flow sensor provides accurate real-time control and display of dosing rate.

Set point control allows the desired flow rate to be simply programmed into the pump. Through feedback from the EFS sensor, the pump constantly adjusts its speed to maintain the set dosing rate - even under changing temperature, viscosity or suction and discharge pressure conditions.

The EFS is mounted directly on the pump for accurate dosing rate measurement - ALL WITHOUT ANY TIME-CONSUMING CALIBRATION.

The EWN-Y provides a clear display of actual dosing rate and a 4-20 mA output signal proportional to the flow rate.

An optional Auto Air Vent Valve (NAE) can be mounted in-line with the EFS sensor to eliminate gas-lock conditions quickly with continuous venting.

Operating history such as total flow return and power-on time are stored in memory and can be used for diagnostic troubleshooting.

  • The EWN-Y pump automatically recognizes the EFS sensor when connected and powered.

  • An injection check valve is required when discharge-line length is less than 10 feet. An in-line check valve (purchased separately) is required when discharge-line length is over 10 feet.

  • The EFS sensor requires a minimum conductivity of 10 mS/cm to measure flow accurately. Presence of non-conductive media (i.e. oil) in the flow may generate erroneous readings.

The addition of the larger EFS-10 sensor allows the EWN-Y Pump + EFS sensor combination to expand the full range of EWN pumps.  All the features and benefits of the EFS sensor and EWN-Y pump are now available from the 0.6 GPH to 6.7 GPH!
