Product Introduction
Industrial rubber diaphragms for water‑system equipment are flexible elastomer sealing partition components manufactured by compression vulcanization. Main materials include water‑resistant EPDM, NBR and optional fabric‑reinforced structures with polyester fabric. Flat‑type and corrugated‑wave structures are available. Featuring excellent water‑resistance, anti‑aging performance and outstanding flex‑fatigue resistance under repeated deformation. Operating temperature‑40℃‑120℃ depending on rubber compound. The diaphragm isolates water medium and driving‑pressure chambers, transmits pressure‑driven displacement while preventing medium mixing and leakage. Widely applied in water solenoid valves, pressure regulators, diaphragm pumps and water‑treatment control valves for municipal water‑supply, water‑treatment and fluid‑control systems. Standard sizes for mainstream water‑control components are in stock. Custom dimension, thickness, corrugation structure, rubber hardness and OEM marking are supported per drawings or samples for water‑equipment OEM assembly and aftermarket replacement projects.
