‌Electro-magnetic Fluorine-lined Diaphragm Pump‌ is a diaphragm pump driven by an electric motor, with core components including the pump housing, diaphragm, drive mechanism, and inlets and outlets with one-way valves. The pump housing serves as the outer shell of the entire unit, providing support and protection for the internal parts. Common materials include cast iron, stainless steel, aluminum alloy, and various engineering plastics.

Working Principle

The working principle of the electric fluorine-lined diaphragm pump is to drive the diaphragm to reciprocate by an electric motor, thereby altering the flow rate of the fluid medium. When the diaphragm moves to one side, a vacuum is formed inside the pump cylinder, drawing in the liquid; when it moves to the other side, it discharges the liquid. This design ensures that the fluid being conveyed only contacts the internal side of the pump cylinder, inlet valve, outlet valve, and diaphragm, effectively protecting the critical components.
