Automatic flow adjustment: Pneumatic diaphragm pumps use air as a power source, and their flow rate will automatically adjust with the change of back pressure (outlet resistance), which is particularly suitable for medium and high viscosity fluids. In contrast, centrifugal pumps and gear pumps require additional equipment such as reducers or frequency converters in the transportation of fluids with slightly higher viscosity, which is more expensive.
Wide applicability: Diaphragm pumps are suitable for a variety of complex fluid transportation tasks, including flammable, explosive, corrosive, viscous or solid-containing media. Its design is simple and efficient, and can cope with various harsh working environments, such as flammable and explosive environments, harsh construction sites, etc.
Environmental protection and energy saving: Pneumatic diaphragm pumps use compressed air as a power source, and will not generate sparks or overheating during operation, which is particularly suitable for use in flammable and explosive environments. In addition, the diaphragm materials of pneumatic diaphragm pumps are diverse, and suitable materials and sealing materials can be selected according to different liquid media to ensure the durability and stability of the pump.
Easy maintenance: The diaphragm pump has a simple structure, few wearing parts, and is easy to install and repair. Due to its design, the transported medium will not contact the moving parts such as the gas distribution valve and connecting rod, reducing the performance degradation caused by component wear.
Self-protection function: The diaphragm pump has a self-protection function. Once it is overloaded, the pump will automatically shut down and automatically start again after the load returns to normal, ensuring the safe operation of the equipment.
