JLM-S metering pump is a microprocessor controlled solenoid diaphragm pump with changeable frequency. It is capable for all kinds of solutions dosing, including corrosive solutions. It is widely used in petroleum, chemical, food, pharmaceutical, paper, light industry, agriculture, water conservancy and other industrial and technological sectors, in the process solution metering and dosing. Solenoid metering pump is the use of electromagnetic push rod driven diaphragm in the pump head reciprocating movement, causing the pump head chamber volume and pressure changes. Changes in pressure caused by suction valve and discharge valve opening and closing, to achieve quantitative liquid.
JLM-S solenoid metering pump rated flow range is 1 ~ 20 l / h, with corresponding maximum output pressure of 10 ~ 1bar. The pump outlet displacement can be adjusted according to the pulse frequency selection switch. It is a simple structure, low energy consumption, accurate measurement, with a new screen display of electromagnetic diaphragm metering pump.

Power supply in some areas is unstable. Excessive fluctuations in power supply affect the use of equipment, and even cause damage to the pump. JLM-S solenoid metering pump power supply range is ± 10% of the rated voltage(for details, please refer to the relevant technical information). For areas where the supply voltage fluctuates or the surge voltage exceeds the allowable range, please install an AC regulated power supply. Equipment loss due to over voltage of power supply, our company does not assume the responsibility of quality assurance.
