Features & Benefits
Summary of Key Benefits
  • 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.

  • Universal Voltage The Universal Voltage Function enables the EJ Series to operate at any AC voltage. The EJ Series also conform to global Standards.

  • External Control The EJ Series have both digital input and Stop/Start inputs built into the pump, enabling either proportional or On/Off 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.
