EWN Series Metering Pumps

The EWN Series electronic metering pumps offer superior high speed dosing capability with more standard features. The flexibility of the EWN pump enable it 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 pump for the most demanding applications.

• 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.
