The EW Series Digital Metering Pumps utilize an IP65 (NEMA 4X) construction for superior performance in wet and humid environments.

The EW Series are solenoid-driven, diaphragm metering pumps with capacities up to 6.7 GPH (25.4 l/h) and a maximum pressure of 150 PSI (10 bar).

At 360 strokes per minute, the EW Series provides an outstanding 1800:1 turndown ratio and will reduce the slug feeding found in most competitive pumps. The EW Series includes a variety of controls including feed verification, totalization, easy calibration, pulse/analog input and quick-prime features. The membrane switches and stroke control of the pump are mounted opposite the liquid end, under a protective, clear cover. The display utilizes a high temperature LCD that provides extra protection from sunlight in outdoor applications. The high compression ratio of the EW's liquid end combined with the double check valves result in the ability to prime quickly and maintain prime. The EW is backed with a complete 2-year warranty including the liquid end and diaphragm.
