Dosing Pumps
Electromagnetic Metering Pump
An electromagnetic metering pump is a precision-dosed pump with a diaphragm vibrated by a solenoid that injects a precise amount of chemical with each stroke. Capacity is adjusted by stroke frequency; it ensures regular and accurate delivery of chemicals such as chlorine, acid, flocculant and corrosion inhibitor.
Available with PTFE diaphragm, PVC or PVDF pump head and IP65 enclosure; on-off, analog and signal (proportional) controlled, level control input models are offered. Suction kit, injection valve, solution tank and stands are also supplied.
