JLM series solenoid diaphragm metering pump is effective and reliable digital pump for nearly all chemical dosing. The solenoid shaft is sucked by the magnetic wire and pushed back by the spring, which makes the diaphragm in the dosing head suck and discharge. The check valves which with double balls prevent backflow when pumping.The precise dosing can be controlled both by the stroke length and stroke speed manually. The capacity range is from 1.0l/h to 20l/h at a back pressure from 10 bars to 1bar. All most any chemical with low viscosity can be dosed with JLM solenoid diaphragm metering pump.It is an economical meterng pump widely used in dosing applicaitons.
