Walchem Chemical Metering Pumps

Walchem Chemical Metering Pumps are precision-engineered positive displacement pumps specifically designed for accurate chemical dosing in water treatment, industrial processes, and agricultural applications. They are designed to handle various chemicals and fluids into water and wastewater treatment, agriculture, and many other industries, working on the principle of positive displacement, meaning the pumps will displace a fixed amount of fluid with every pump stroke. Walchem is a leading manufacturer of on-line electronic metering pumps, integrating sensor, pump and electronic technologies for chemical control. The company's product line includes the EWN Series electronic metering pumps that offer superior high speed dosing capability with more standard features and the robust LK Series metering pump which features a motor-driven, mechanically actuated diaphragm design with a maximum capacity of 114 GPH (432 l/h) and a maximum pressure of 225 PSI (1.5 MPa). Designed to withstand abusive conditions in process applications, Walchem pumps offer high-speed dosing capability, making them the preferred choice for precise chemical feed applications where accuracy, reliability, and durability are essential.
