EK series metering pumps from Walchem are solenoid-driven and feature capacities up to 6.7 GPH (25.4 l/h) and a maximum pressure of 150 PSI (10 bar). Engineered for indoor and outdoor applications, the EK series offers an 1800:1 turndown ratio that will reduce slug feeding, according to the manufacturer. The pumps’ membrane switches and stroke control are mounted opposite the liquid end, under a protective, clear cover.
