Diaphragm pumps are a type of positive displacement pump that pumps liquid or gas by the up and down movement of the diaphragms. They are generally used in chemical transfer, wastewater treatment, dosing and similar applications. Some main features are:
Functioning of Diaphragms: The operation of pumps occurs by expansion of one side of the diaphragm under pressure and then compression or stretching of the other side. This pumps the liquid or gas.
Chemical Resistance: Diaphragm pumps made of chemically resistant materials are generally used to transfer aggressive or corrosive substances.
Self-Priming Feature: Some models may have the ability to absorb liquid, which can offer a more effective and efficient operation.
Ability to Transport Solid Particles: Certain models may have the ability to transport solid particles or high viscosity liquids.
Safety Valves: There may be integrated valves for safety in overpressure situations.
Diaphragm pumps are widely used in various industries due to their functionality and chemical resistance. They find use in areas such as the chemical industry, pharmaceutical industry, agriculture, automotive, water treatment plants and food processing.
