Mechanical Diaphragm Pump

Mechanical Diaphragm Pump

A Mechanical Diaphragm Pump is a positive displacement metering pump designed for accurate and reliable chemical dosing in industrial and water treatment applications. It is widely used in ETP, STP, water treatment plants, chemical processing, pharmaceuticals, power plants, cooling towers, and boilers where precise dosing and safe chemical handling are essential.In a mechanical diaphragm pump, the diaphragm is actuated by a mechanical drive mechanism such as a cam or crankshaft. This motion displaces fluid in a controlled manner, ensuring consistent flow rates proportional to the pump speed and stroke length. The diaphragm acts as a barrier between the process fluid and the drive mechanism, providing leak-free operation and enhanced safety when handling hazardous or corrosive chemicals.Mechanical diaphragm pumps are suitable for dosing a wide range of chemicals including acids, alkalis, coagulants, flocculants, biocides, sodium hypochlorite, and specialty chemicals. Their rugged construction allows them to operate reliably under moderate to high-pressure conditions.
