Diaphragm Pumps and Parts

As the professional manufacturer, Xiafeng would like to provide you high quality Diaphragm Pumps and Parts, it also known as reciprocating displacement pumps, operate through the reciprocating deformation of a diaphragm to change the chamber volume and transfer liquid. They are a type of actuator widely used in industries such as chemical processing, ceramics, and wastewater treatment. The main structure consists of a drive mechanism and a diaphragm head, with motion driven by hydraulic, pneumatic, or electric systems.

Key Features and Structure:

Working Principle: The diaphragm isolates the working medium from the driving mechanism, preventing contamination and leakage. This makes it suitable for handling corrosive, toxic, or high-purity fluids.

Material Composition: The diaphragm is typically made from corrosion-resistant materials such as fluoroelastomer (FKM) or polytetrafluoroethylene (PTFE).

Pneumatic Diaphragm Pumps: Operated by compressed air, they can self-prime up to 7 meters, handle particles up to 10 mm in diameter, and withstand temperatures up to 150°C. They are suitable for flammable, toxic, or high-temperature media and can automatically stop when blocked or running dry.

Electric Diaphragm Pumps: Provide a lifting head up to 30 meters, offering stable flow and energy-efficient operation for continuous use in industrial systems.
