At Exactseal, our commitment to precision engineering is exemplified in our comprehensive diaphragm manufacturing capabilities, offering versatile solutions tailored to diverse industry needs. Our fabric-reinforced diaphragms seamlessly combine the flexibility of rubber with reinforced strength, providing enhanced durability for applications demanding increased tensile strength and resistance to wear and tear.

Leveraging the unique properties of Polytetrafluoroethylene (PTFE), our PTFE-coated diaphragms stand out for their exceptional chemical resistance and temperature stability, making them well-suited for environments with aggressive chemicals and extreme temperatures and pressure. This ensures reliable performance in demanding applications.

The versatility of our diaphragm solutions extends to rolling diaphragms, designed for optimal flexibility and longevity. With applications spanning industries such as automotive, aerospace, and medical, our rolling diaphragms showcase efficient and reliable movement, making them suitable for dynamic systems.

Specifically engineered for precise control of fluid flow in pumps and valves, our pump and valve diaphragms are crafted with materials ensuring resilience, chemical resistance, and longevity. These diaphragms play a crucial role in fluid-handling systems, contributing to their efficiency and reliability. Our customers in different industry sectors and OEMs rely on us for their mission-critical Rubber diaphragm needs including:

• Pumps and valve manufacturers: leverage our diaphragms to act as seals in pumps and valves to regulate the flow of liquids and gases.
• Pharmaceutical manufacturers: They are used to regulate the flow of fluid/API delivery during injectables and oral suspension manufacturing.
• Actuators: They convert pneumatic or hydraulic pressure into mechanical movement in actuators while ensuring a consistent pressure differential between the media.
• Automotive industry: They are used in various automotive components, such as fuel injectors and vacuum pumps.
• Aerospace industry: They are used in aircraft and spacecraft components for various sealing and actuation purposes.

We have years of experience in manufacturing rubber diaphragms in all shapes and sizes, from tiny discs to sheets spanning meters. Furthermore, We manufacture them in different hardness durometers (softer diaphragms with Shore A 40-50 Duro for delicate tasks and harder ones with Shore A 70-80 Duro for high-pressure applications like in case of oil refinery, gas pipes, or beverage bottling).

Common types of rubber diaphragms we manufacture to serve our customer and their diverse range of applications include:

• Flat Diaphragms: These workhorses are thin sheets, perfect for basic sealing and separating functions. Think check valves or pump membranes.
• Convoluted Diaphragms: Imagine an accordion made of rubber. These boast folds and bellows, increasing surface area and flexibility for pumping, metering, and regulating fluids.
• Dish-Shaped Diaphragms: Picture a shallow bowl. These diaphragm cup liquids, ideal for applications like dispensing or pressure relief valves.
• Rolling Diaphragms: Think of a top hat-shaped rubber diaphragm that combines the properties and function of both Bellows and Diaphragms. These diaphragms continuously move fluids or gases, often used in hygienic applications like food and pharmaceutical processing among others.

Lastly, we have proven expertise in manufacturing these diaphragms from a variety of rubber compounds while reinforcing them with a variety of meshes/fabrics like nylon, dacron, nomex, kevlar, cotton, and steel to name a few. In a quick summary, here are a select few materials that we use to manufacture our diaphragms for your reference to help select the ideal rubber compound based on your diaphragm operating condition:

• EPDM (Ethylene Propylene Diene Monomer): A champion against water, steam, and ozone, EPDM excels in outdoor and plumbing applications.
• Nitrile (NBR), FKM (Viton), FFKM (Kalrez): Oil and fuel are no match for these elastomers, making it a go-to for automotive and industrial pumps while FDA compounds of these rubbers are used widely in Pharmaceutical applications for their chemical resistant properties.
• Silicone: Biocompatible and heat-resistant, silicone is ideal choice of material in medical devices and food processing equipment.
• Neoprene: Weatherproof and abrasion-resistant, neoprene tackles harsh environments like construction and mining.
