EJ Pump

The EJ Series provide precise chemical injection at an economical price. Universal voltage capability enables operation from 100 - 240VAC in virtually all countries. The EJ Series are compact, simple to operate and have outputs to 1.3 GPH (4.8 LPH) and a maximum pressure of 175 PSI (1.2 MPa).

  • 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.
