MLS SERIES

PULSE/4-20mA CONTROL SOLENOID DRIVEN DOSING PUMP

MLS 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 4 valve and discharge valve opening and closing, to achieve quantitative liquid suction and discharge. MLS 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.

What is the difference with ML Series?

The main difference between ML and MLS Series is the option to control remotely. The MLS Series has an additional signal connection for 4-20mA signal or pulse connection. While ML Series does not have this option. Other than that, all parameters perform the same.
