Diaphragm pumps are crucial in various industries, providing reliable fluid transfer. The choice of materials in their construction plays a pivotal role in their performance, durability, and compatibility with different applications.
The heart of a diaphragm pump lies in its diaphragm, typically made from materials such as rubber, thermoplastics, or metal. Each material offers distinct advantages, influencing the pump's efficiency and lifespan. Rubber diaphragms, for example, provide excellent flexibility and chemical resistance, making them ideal for certain applications.
The pump casing and valves are commonly crafted from materials like stainless steel, plastic, or aluminum. These materials ensure corrosion resistance and structural integrity. Stainless steel is often preferred for its robustness, preventing rust and corrosion even in challenging environments.
