Rubber diaphragms are fundamental components in various industrial systems, ensuring reliable control of fluids and gases. Engineered to provide optimal sealing and precise flow management under demanding conditions, these diaphragms are essential in applications ranging from air-operated double diaphragm (AODD) pumps to high-performance dosing pumps. Their durability and adaptability make them indispensable for industries requiring efficiency, safety, and longevity.
At Arvico Rubber Industries, we leverage over 50 years of expertise to manufacture rubber diaphragms that meet the most rigorous industrial standards. Our commitment to quality and innovation has positioned us as a trusted leader in providing customized solutions for industries such as chemical processing, automotive, pharmaceutical, and fluid handling.
The Role of Rubber Diaphragms in Industrial Systems
Rubber diaphragms function as barriers that prevent the unintended transfer of fluids and gases between chambers, ensuring smooth and efficient system operation. They flex under varying pressures and environmental conditions, maintaining a secure seal that isolates different chambers within pumps, valves, actuators, and other fluid control devices.
The function of a rubber diaphragm is to provide consistent and leak-proof performance over millions of cycles. Given their flexibility, durability, and chemical resistance, rubber diaphragms play a crucial role in industries including oil and petroleum, food processing, aerospace, and automotive manufacturing. Their ability to withstand high pressure, corrosive environments, and highly viscous materials makes them a cornerstone of reliable fluid and gas control.
Types of Rubber Diaphragms and Their Specific Applications
1. AODD Pump Diaphragms
AODD pumps are designed to handle viscous fluids and challenging substances. Rubber diaphragms in these pumps enable precise fluid transfer by creating a leak-proof seal.Arvico manufactures AODD pump diaphragms in sizes ranging from 15 mm to 80 mm, delivering superior performance in harsh conditions. Their robust construction ensures extended lifespan and efficiency in industries such as mining, waste management, and chemical processing.
2. Rolling/Cup Type Diaphragms
Rolling diaphragms are essential in fluid control systems, particularly those involving cylinders and pistons. Their primary function is to ensure sealing in systems that require a high degree of movement without compromising efficiency.
Constructed with elastomer and fabric reinforcements, these diaphragms offer flexibility while maintaining tight seals. Arvico customizes rolling diaphragms to suit specific applications in hydraulic systems, automotive components, and fluid metering solutions, ensuring precise movement and sealing.
3. Dosing/Metering Pump Diaphragms
Dosing and metering pumps require precise fluid regulation, particularly when handling aggressive chemicals. The rubber diaphragms in these pumps must provide a secure, leak-proof seal to prevent contamination and ensure consistent performance.Arvico manufactures PTFE-laminated diaphragms with embedded inserts, specifically designed for use in dosing pumps. The PTFE layer ensures the diaphragm’s resistance to chemical exposure, extending its lifespan and maintaining secure sealing in applications like chemical processing and pharmaceuticals.
