Description

Technical Field

[0001] This application relates to an easy-to-clean pneumatic diaphragm pump, belonging to the field of pneumatic diaphragm pump technology. Background Technology

[0002] Pneumatic diaphragm pumps are a new type of conveying machinery that uses compressed air as a power source. They can pump out all kinds of corrosive liquids, liquids containing particles, and liquids that are highly viscous, volatile, flammable, or highly toxic.

[0003] A serious problem with existing pneumatic diaphragm pumps is their inability to effectively rinse away contaminants after cleaning. Waiting until all cleaning is complete before rinsing causes the contaminants to re-adhere to the diaphragm surface, making them difficult to remove and reducing cleaning efficiency. Furthermore, when pumping liquids, impurities in the liquid can easily accumulate inside the pump, eventually causing blockages, affecting normal operation, shortening the pump's lifespan, and requiring significant time and manpower for disassembly and repair.

[0004] Therefore, there is a need to provide a pneumatic diaphragm pump that is easy to clean, improves cleaning efficiency, and reduces the manpower and material costs associated with cleaning the diaphragm pump. Utility Model Content
