Our rubber diaphragms are precision-engineered flexible membranes designed to separate, control, or transfer fluids and gases in a wide range of industrial applications. Made from high-quality rubber materials including NBR, EPDM, silicone, and FKM, these diaphragms are engineered to provide excellent durability, flexibility, and chemical resistance, ensuring reliable performance in pumps, valves, regulators, and actuators.
Key features of our rubber diaphragms include a thin, uniform thickness (0.1mm to 10mm) that allows for precise movement and control, excellent resistance to extreme temperatures (-50°C to 250°C), and low compression set, ensuring long-lasting flexibility and sealing performance. NBR diaphragms are ideal for oil and fuel applications, offering superior resistance to hydrocarbons. EPDM diaphragms provide excellent weather and chemical resistance, suitable for water and wastewater treatment systems. Silicone diaphragms are non-toxic and compliant with FDA standards, making them a top choice for food & beverage and medical applications. FKM diaphragms excel in high-temperature and aggressive chemical environments, suitable for chemical processing and aerospace industries.
These diaphragms are available in various shapes (circular, rectangular, custom) and sizes, to meet the unique needs of different equipment. They are widely used in positive displacement pumps, control valves, pressure regulators, and hydraulic actuators, where they play a critical role in controlling flow rates, pressures, and fluid separation. Their primary advantages include a long service life (up to 5 years under normal operating conditions), high tear resistance (≥30 kN/m), and easy replacement, reducing downtime and maintenance costs. We offer custom diaphragm solutions, including special materials, coatings, and reinforced layers, to meet OEM/ODM requirements. All our diaphragms comply with international standards such as ISO 9001, RoHS, and REACH, ensuring quality and safety. With a MOQ of 100 pieces and competitive pricing, we are a trusted supplier of rubber diaphragms to global industries.
