About HSN/HNBR Diaphragms

Rubber Diaphragms with good elasticity level are reckoned as specially designed membranes that are fitted between two chambers on their circumference. Depending on pressure level, these diaphragms change their position by shifting one chamber slightly upward or downward over another chamber.

The unique flexibility of these diaphragms is useful for inhibiting conveyance of working fluid between two chambers by enabling the effects of pressure to pass the barrier sans interchanging any media. The rubber made diaphragms are of two types. The Static variation of these items is instrumental in isolation of two different fluids and it moves slightly or remains fixed. Their dynamic variant acts as suitable sealing medium between fixed and movable items and has key role in transferring pressure or force.

Diaphragm seal is used to get accurate response during change of pneumatic or hydraulic pressure. These diaphragms are used as essential sealing components for smooth operation of different machinery utilized in automotive, oil and gas refineries, aerospace manufacturing, valve production, medical instruments and pump manufacturing industries.

MREW is involved in manufacturing of wide array of diaphragms that are meant for ensuring trouble free functioning of pressure sensors in pneumatic systems, pumps, control valves for accurate flow controlling purpose, pneumatic diaphragm pumps, wax actuators, high pressure diaphragm pumps, thermal actuators, diaphragm pressure gauges, pneumatic actuators, diaphragm vacuum pumps, actuators, diaphragm air compressors, diaphragm metering pumps and diaphragm fuel pumps. We have expertise in manufacturing of Rubber Diaphragms that have been made by using EPDM, silicon, neoprene, viton,natural, nitrile and other grades of rubber.


Flexible Sealing for Extreme Conditions

HSN/HNBR diaphragms provide robust protection and reliability under harsh environmental conditions involving temperature fluctuations, aggressive chemicals, and exposure to fuels or gases. Their innovative design and material engineering allow them to maintain integrity and sealing performance in automotive and industrial machinery, pumps, valves, and regulators.


Superior Material & Customization

Selection ranges from standard to custom sizes and styles, including reinforced and colored variants to precisely suit design requirements. Compression, injection, or transfer molding delivers optimal shape and performance. Polyester or nylon fabric reinforcement is available for added mechanical strength.

FAQs of HSN/HNBR Diaphragms:


Q: How are HSN/HNBR diaphragms typically installed in equipment?

A: HSN/HNBR diaphragms can be installed using press-fitted, clamped, or as integrated components within assemblies, depending on the specific equipment design and sealing requirements.

Q: What benefits do HSN/HNBR diaphragms offer compared to natural rubber alternatives?

A: These diaphragms deliver higher resistance to oils, fuels, hydrocarbons, ozone, and aging, along with lower gas permeability, increased durability, and extended service life. They outperform natural rubber in harsh operating environments.

Q: Where can HSN/HNBR diaphragms be used?

A: HSN/HNBR diaphragms are used in automotive systems, industrial machinery, pumps, valves, fuel systems, gas regulators, and various control equipment requiring high-performance sealing.

Q: What is the recommended compression ratio for effective sealing?

A: A compression ratio of 1020% is recommended to ensure optimal sealing performance for these diaphragms.

Q: How does reinforcement improve diaphragm performance and when is it needed?

A: Polyester or nylon fabric reinforcement enhances tensile strength and tear resistance, making diaphragms suitable for applications demanding higher mechanical stability or durability in dynamic operations.

Q: What are the customization options available for HSN/HNBR diaphragms?

A: Customization is offered for color, size, thickness (0.3 mm to 6 mm), diameter (12 mm to 600 mm), and style (flat, molded, reinforced), with tolerances as tight as 0.05 mm to 0.1 mm, tailored to customer specifications.
