Our rubber diaphragms are engineered with precision, durability, chemical resistance, and long cycle life, specifically tailored for the harsh environments of Sabah, Sarawak, and Brunei.

 

 What is a Rubber Diaphragm? – Deep Technical Explanation

A rubber diaphragm is a flexible elastomeric membrane designed to act as a dynamic sealing interface between two chambers. It provides a controlled barrier that prevents the mixing or contamination of:

• Liquids
• Gases
• Fuels
• Oils
• Air
• Chemicals
• Vapour
• Slurry

Rubber diaphragms operate through pressure-driven displacement, meaning the diaphragm flexes or deforms in response to changes in pressure, vacuum, or hydraulic force while maintaining a fluid-tight and gas-tight seal.

Why RUBASIA’s Rubber Diaphragms Perform Better

• Precision-engineered thickness tolerance
• Reinforced fabric layers for high burst strength
• Excellent rebound memory (returns to shape after flexing)
• Highly resistant to tearing and fatigue
• Stable performance in temperature extremes
• Designed for millions of flex cycles

 

 Materials Used for RUBASIA Rubber Diaphragm (Ultra Technical Breakdown)

We manufacture using the highest grade materials to ensure optimum performance:

1. NBR (Nitrile Rubber) Diaphragm

• Excellent resistance to oils, fuels, diesel, petrol
• Suitable for automotive, fuel metering, chemical plants
• Temperature range: –30°C to +100°C

2. EPDM Diaphragm

• Best for hot water, steam, chemicals, ozone, UV
• Common for water systems, pumps, regulators
• Temperature range: –40°C to +150°C

3. Neoprene (CR) Diaphragm

• Balanced resistance to weather, ozone, moderate oils
• Ideal for outdoor industrial equipment
• Temperature range: –35°C to +110°C

4. Silicone Diaphragm

• High heat tolerance
• Food-grade compatible
• Temperature range: –60°C to +230°C

5. Viton (FKM) Diaphragm

• Ultimate resistance to chemicals, solvents, hydrocarbons
• Ideal for oil & gas, petrochemical, high-temperature systems
• Temperature range: –20°C to +250°C

6. Fabric-Reinforced Diaphragm

• Nylon-insert / Polyester-insert / Canvas-insert
• For extreme pressure applications
• Prevents ballooning or uneven deformation

 

 Key Functions of Rubber Diaphragm (Expanded Engineering Detail)

1. Precision Sealing Function

Creates a 100% leak-proof barrier between chambers, preventing cross-contamination of fluids or gases.

2. Controlled Pressure Regulation

Flexes in response to pressure and vacuum changes, enabling accurate flow control in:

• Control valves
• Pressure regulators
• Dosing pumps
• Air-operated equipment

3. Dynamic Movement (Flexible Control Element)

Works as a dynamic mechanical component, allowing:

• Pump cycling
• Valve opening/closing
• Regulation of flow and pressure

4. Chemical & Thermal Stability

Designed to withstand:

• Hydrocarbons
• Chemical by-products
• High temperature
• High humidity (common in Borneo climate)
• Salt air (marine areas: Kota Kinabalu, Labuan, Sandakan, Bintulu, Miri)

5. Long Flex-Fatigue Life

Engineered to operate for hundreds of thousands to millions of cycles without cracking.
