EWN Series

The EWN Series electronic metering pumps offer superior high-speed dosing capability with more standard features. The flexibility of the EWN pump enables it to be integrated into virtually any chemical feed application using a universal-voltage, digital controller with an expanded set of control features. Superb valve performance and advanced solenoid engineering combine to make a highly precise dosing pump for the most demanding applications.

Features of integrating the EFS Sensor with the EWN-Y Pump:

• The EWN-Y Series pump combined with EFS flow sensor provides accurate real-time control and display of the dosing rate.
• Set point control allows the desired flow rate to be simply programmed into the pump.  The pump will change rate to achieve the target flow rate – ALL WITHOUT ANY TIME-CONSUMING CALIBRATION.
• The EFS is easily mounted directly to the pump discharge, connects to the control unit with supplied connector, and self recognizes and initializes the sensor.
• The EWN-Y provides a clear display of actual measured dosing rate and provides a 4-20 mA output signal proportional to the flow rate.
• The optional Auto Air Vent Valve (ADV) can be mounted in-line with the EFS sensor for a combination to eliminate gas-lock conditions quickly with continuous venting.
• Operating history such as total volume, number of strokes, power cycles and power-on time are stored in memory and can be viewed for validation.
