Nitrile (NBR or Buna-N) Diaphragms

About Nitrile (NBR or Buna-N) 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.

High-Performance Sealing Solutions

Nitrile rubber diaphragms deliver outstanding oil and fuel resistance, a crucial feature in automotive, fuel handling, and industrial applications. Their impressive elasticity ensures reliable performance in dynamic sealing environments where flexibility is essential. Adaptable to a range of temperatures and pressures, these diaphragms withstand challenging operating conditions, providing long service life and minimizing maintenance downtime. Their popularity stems from both their robust construction and their customizable dimensions.


Versatile Customization for Your Needs

Our NBR diaphragms are available in a variety of widths, diameters (up to 1000mm), thicknesses (0.5mm to 5mm), and surface finishes (smooth, matte, or textured). Custom and standard sizes are easily accommodated. Reinforcement types such as nylon, polyester, or cotton can be added, or bonded metal inserts for specialized applications. This flexibility ensures optimal fit and function in automotive, chemical, pumping, and hydraulic systems.
