Signal Controlled Solenoid Diaphragm Metering Pump
JLM-S series solenoid diaphragm metering pump is LIGAO newly designed digital pump with an advanced microprocessor control board. The innovative big LED screen display the instant flow rate and the accumulated flow for easy reading. It has the same advantage of JLM manual model. The precise dosing can be controlled by the stroke speed both manually and automatically. The capacity range is from 1.0l/h to 20l/h at a back pressure from 10 bars to 1bar.
