Dongguan Chengda Launches High-Durability Cloth-Reinforced Diaphragm for Industrial Pump Applications

27 May, 2026

Dongguan Chengda Rubber & Plastic Technology Co., Ltd., a leading manufacturer of precision rubber and silicone sealing components, today announced the launch of its new high-durability cloth-reinforced diaphragm, specifically engineered for demanding industrial pump applications.

 

The newly developed diaphragm combines high-strength fabric reinforcement with advanced rubber compounding technology, delivering exceptional tear resistance, pressure endurance, and extended service life. Unlike conventional rubber diaphragms that may fail under repeated flexing or high-pressure cycles, Chengda’s cloth-reinforced design maintains structural integrity even in harsh operating conditions, including exposure to oils, chemicals, and temperature fluctuations.

 

“Industrial pumps require diaphragms that can withstand millions of cycles without compromising performance. Our new cloth-reinforced diaphragm directly addresses this need,” said a spokesperson from Chengda’s R&D department. “By optimizing both the fabric layer and the rubber formulation, we have achieved a product that offers superior durability while maintaining excellent sealing properties.”

 

Key features of the new cloth-reinforced diaphragm include:

  • High tensile strength and abrasion resistance

  • Excellent compatibility with fuels, hydraulic fluids, and various chemicals

  • Stable performance across a temperature range of -40°C to +120°C

  • Customizable sizes, shapes, and fabric types to suit different pump designs

 

The product is suitable for a wide range of industrial equipment, including air-operated double-diaphragm (AODD) pumps, fuel transfer pumps, chemical dosing pumps, and water treatment systems. In addition to the new diaphragm, Chengda continues to offer its full portfolio of rubber and silicone sealing solutions, including leather bowls, lip seals, gaskets, O-rings, and custom-molded components for the automotive, medical, electronics, and home appliance sectors.

 

Chengda’s strong in-house R&D team can rapidly develop molds and material formulations based on customer specifications, while advanced production equipment and a strict quality control system ensure consistency from raw materials to finished products. The company also supports low-volume prototyping and high-volume mass production with short lead times.
