Product Description:
These premium replacement diaphragms are specially engineered for use with QBY/K series pneumatic diaphragm pumps. Crafted from robust elastomers and advanced engineering plastics, they offer reliable performance and durability under various operating conditions.
Customers can choose from three distinct material options tailored to specific applications: NBR (nitrile rubber) suitable for general-purpose oil and water handling, F46 (a modified PTFE fluoropolymer) designed to withstand aggressive chemicals, and imported PTFE (polytetrafluoroethylene) which provides exceptional chemical resistance and meets stringent high-purity standards.
These diaphragms are available in multiple sizes, featuring outer diameters ranging between 140 mm and 450 mm. They come with standard bolt hole patterns, such as the 10-hole configuration, as well as plain-edge designs to accommodate diverse pump models. Each diaphragm is precision-molded to guarantee optimal sealing, extended flex life, and consistent, reliable pumping performance.
Ideal for replacing worn or damaged components, these diaphragms are widely used in slurry, chemical, food processing, and mining transfer pumps, ensuring efficient operation even in the most demanding industrial environments.
Features:
Material Options
NBR (Nitrile): This material offers excellent resistance to oil, fuel, and water. It operates effectively within a temperature range of -30°C to +100°C, making it suitable for various demanding environments.
F46 (Fluoropolymer): Known for its outstanding chemical resistance, F46 can withstand exposure to acids, solvents, and strong oxidizers. Its temperature tolerance spans from -20°C to +150°C.
Imported PTFE: Featuring a superior non-stick surface, Imported PTFE is inert to almost all chemicals. This makes it ideal for food and pharmaceutical applications where cleanliness and chemical resistance are critical.
Specifications
Diameter Range: The products are available in diameters ranging from 140 mm to 450 mm, catering to a variety of pump models.
Bolt Hole Configurations: They come equipped with a standard 10-hole pattern for larger sizes or a plain-edge option without holes suitable for clamp-style mounting systems.
Performance Features
High Flexural Fatigue Resistance: These materials are engineered to endure millions of cycles without cracking, ensuring durability and reliability over time.
Precision Molding: The components are precisely molded to guarantee an accurate fit and effective sealing against pump housings.
Interchangeable: Designed as direct replacements for QBY/K10-15, K25-40, K50-65, and K80-100 series pumps, facilitating easy integration.
Cost-Effective: Utilizing these materials can extend the pump’s service life and significantly reduce downtime, offering excellent value.
Color-Coded Options: For special applications such as abrasion resistance, blue polyether (polyurethane) variants are available.
