Rubber Diaphragms
Custom Rubber Diaphragms for Pressure Control & Sealing Applications
Rubber diaphragms are flexible sealing components designed to control fluid flow and maintain reliable sealing in pressure-operated systems. Their elastomer construction allows repeated movement while resisting deformation, ensuring consistent performance under varying pressure, temperature, and operating conditions.
Rubber diaphragms are widely used in pressure regulators, pumps, valves, dosing systems, actuators, and industrial control equipment, where long service life and reliable sealing are essential.
We manufacture custom rubber diaphragms in a variety of materials and designs to meet specific application requirements, providing excellent durability, sealing performance, and operational efficiency.
ATC Rubber manufactures custom rubber diaphragms, PTFE-laminated diaphragms, metal-reinforced diaphragms, and industrial sealing solutions for pumps, valves, regulators, and pressure control systems.
Standard Rubber Diaphragms
Standard rubber diaphragms are flexible sealing elements designed for pressure-operated systems. Manufactured from high-quality elastomer compounds, they provide reliable movement, excellent sealing performance, and long service life across a wide range of industrial applications.
Metal-Reinforced Rubber Diaphragms
Metal-reinforced rubber diaphragms combine the flexibility of elastomers with the strength of integrated metal inserts. They are designed for high-pressure, high-cycle applications requiring superior dimensional stability and long-term mechanical performance.
PTFE-Laminated Rubber Diaphragms
PTFE-laminated rubber diaphragms combine the flexibility of elastomer materials with the outstanding chemical resistance and low-friction properties of PTFE (Teflon®). They are ideal for aggressive chemicals, high-cycle operation, and demanding industrial process applications.
Convoluted Rubber Diaphragms
Convoluted rubber diaphragms feature a molded dome-shaped profile that allows greater movement with lower operating force. Their flexible design improves system efficiency, accommodates larger stroke lengths, and minimizes vibration in pressure-operated equipment.
Rubber Diaphragms and Diaphragm Seals
Rubber diaphragms are flexible elastomer products used to provide fluid control and sealing in systems operating under pressure and movement. Thanks to their ability to accommodate repeated movement, they are used in many industrial applications such as pumps, valves, regulators, and dosing systems.
ATC Rubber manufactures diaphragm seals, metal-reinforced diaphragms, PTFE (Teflon)-reinforced diaphragms, and convoluted diaphragms suited to different operating conditions. Different sizes, materials, hardness levels, and design options can be considered depending on the application.
Types of Rubber Diaphragms
Rubber diaphragms can be manufactured in different constructions depending on the pressure, temperature, movement, and chemical resistance requirements of the system they will be used in. Metal-reinforced diaphragms may be preferred in applications requiring increased mechanical strength, while PTFE-reinforced diaphragms may be preferred in systems requiring chemical resistance and low friction.
Convoluted diaphragms, thanks to their special geometry, provide controlled and flexible movement under pressure and can be used in various industrial applications.
Where Are Rubber Diaphragms Used?
Rubber diaphragms are used in pumps, valves, regulators, dosing systems, pressure control equipment, and various industrial machines. Depending on the application, they are chosen for fluid control, sealing, pressure transmission, and separating moving parts from one another.
Depending on the area of use, the diaphragm’s material, thickness, geometry, and reinforcement structure can be determined to develop solutions suited to the operating conditions.
What Should Be Considered When Selecting a Rubber Diaphragm?
When selecting the right rubber diaphragm, operating pressure, temperature, the amount of movement, the fluid it contacts, the chemical environment, and the mounting method should be taken into account. Determining the right material and geometry for the system the diaphragm will be used in is important for sealing performance and the product’s service life.
In particular, the appropriate elastomer material must be selected for different operating conditions such as oil, water, chemicals, and high temperature.
