Tips: Working principle of electric operated double diaphragm pump
The electric motor drives the diaphragm on the plunger son left and right ends through the reducer to make reciprocating motions from left to right. Inside the left and right pump cavities, there are four upper and lower non-return ball valves making motions to change volumes of the working cavities and drive the four non-return ball valves to open and close alternately, thus sucking and discharging the liquid continually.
