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.
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.
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.
