INTRODUCTION
These installation, operation and maintenance instructions cover your electronic metering pump. Refer to the pump
nameplate to determine the actual model.
M M PRINCIPLE OF OPERATION
Diaphragm metering pumps are used to dispense chemicals or fluids. This is achieved by an electromagnetic
drive mechanism (solenoid) which is connected to a diaphragm. When the solenoid is pulsed by the control
circuit, it displaces the diaphragm which, through the use of check valves, moves the fluid out the discharge
under pressure. When the solenoid is deenergized it returns the diaphragm and pulls more fluid into the
pumphead and the cycle repeats.
The stroke rate of the pumps is controlled via the touchpad and present status is indicated by the LCD display.
The stroke length is controlled via the stroke length knob.
