Features of EJ series
High Speed Performance
The EJ Series operate at 360 strokes-per-minute, providing high resolution chemical feed and high turndown capability. Most competitive products operate at slower speeds, resulting in slug feeding, accelerated diaphragm wear and poor feed control.
IP65 Equivalent Protection
A robust housing protects the pump from normal wear. Mounting the Digital Display and Key Pad control within the drive housing creates a highly water resistant design. A clear cover further protects the pump from liquids.
Universal Voltage
The Universal Voltage Function enables the EJ Series to operate at any AC voltage. The EJ Series also conform to global standards.

*1 The maximum applied voltage from the EJ to an external contact is 15 V at 3 mA. When using a mechanical relay, the minimum application load should be 3 mA or below.
*2 When the external pulse signal is entered to run the pump over the max. spm, the signal is cancelled.
*3 Observe the allowable voltage range of 90 to 264 VAC. Otherwise failure may result.
