The Walchem EJ Series metering pumps provide precise chemical injection while being compact and simple to operate. It operates 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.
The EJ Series have both digital input and Stop/Start inputs built into the pump, enabling either proportional or On/Off control. They also have IP65 equivalent protection with a robust housing, protecting 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.
