Chemical metering pumps
Walchem Corp., of Holliston, Mass., introduces the EHE Chemical Metering Pumps, which are the most powerful electronic metering pumps available. The pumps have outputs up to 20 gph and pressures up to 150 psi—the perfect choice for water and wastewater chemical feed applications. A variety of liquid end options are available for disinfection, pH adjustment, corrosion control, coagulation/flocculation and fluoridation, among others. Tightly guided check valves and up to 360 strokes per minute ensure faster priming.
