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 tailored to various industrial needs.
Available in three distinct material variants, the diaphragms cater to different application requirements. The NBR (nitrile rubber) option is suited for general-purpose uses involving oil and water. For handling aggressive chemicals, the F46 (modified PTFE/fluoropolymer) version provides enhanced resistance. Additionally, the imported PTFE (polytetrafluoroethylene) model delivers superior chemical resistance and meets stringent high-purity standards.
The diaphragms come in multiple sizes, with outer diameters ranging from 140 mm up to 450 mm. They feature standard bolt hole patterns, such as the 10-hole configuration, as well as plain-edge styles to fit various pump models. Each diaphragm is precision-molded to ensure an exact seal, extended flex life, and consistent operation under the harshest industrial conditions.
Ideal for replacing worn or damaged components, these diaphragms serve a wide range of applications including slurry handling, chemical processing, food production, and mining transfer pumping. By choosing these high-quality replacements, users can maintain optimal pump performance and minimize downtime.
NBR (Nitrile): This material offers excellent resistance to oil, fuel, and water. It performs effectively within a temperature range of -30°C to +100°C, making it suitable for various industrial applications.
F46 (Fluoropolymer): Known for its outstanding chemical resistance, F46 withstands exposure to acids, solvents, and strong oxidizers. It operates reliably in temperatures from -20°C up to +150°C.
Imported PTFE: Featuring a superior non-stick surface, this material is inert to almost all chemicals. Its properties make it ideal for use in food and pharmaceutical industries.
Diameter Range: The products are available in sizes ranging from 140 mm to 450 mm, enabling compatibility with a variety of pump models.
Bolt Hole Configurations: For larger sizes, a standard 10-hole pattern is supplied, while a plain-edge design with no holes is available for clamp-style mounting options.
High Flexural Fatigue Resistance: Engineered to endure millions of cycles without cracking, ensuring long-lasting durability.
Precision Molding: This process guarantees an accurate fit and effective sealing against pump housings, enhancing performance.
Interchangeability: These components serve as direct replacements for the QBY/K10-15, K25-40, K50-65, and K80-100 series pumps, simplifying maintenance.
Cost-Effective: Designed to extend the service life of pumps and reduce downtime, providing economic benefits.
Color-Coded Options: Blue polyether (polyurethane) versions are available for special applications that require abrasion resistance.

These pumps are highly suitable for the transfer and dosing of various chemicals, including acids, caustics, and solvents. Their design ensures safe and efficient handling of aggressive fluids in industrial environments.
They are also widely used in the circulation of paints, inks, and coatings, providing consistent flow and maintaining the quality of the fluids involved in these manufacturing processes.
In the mining and mineral processing sectors, these pumps excel at managing slurries and mud, offering reliable performance even when dealing with abrasive materials.
Food and beverage industries benefit from these pumps as well, thanks to their construction with PTFE and FDA-compliant materials that meet strict hygiene and safety standards.
These pumps play a crucial role in wastewater and effluent treatment, ensuring effective fluid transfer and contributing to environmental protection efforts.
In the petroleum industry, they are employed for the transfer of fuel and other petroleum products, combining durability with precision.
Additionally, they are ideal for pumping ceramics and glazes, supporting manufacturing processes in the ceramics sector.
The pharmaceutical and bioprocess industries also rely on these pumps for their ability to handle sensitive fluids while maintaining sterility and compliance with industry regulations.
Finally, these pumps serve general industrial fluid transfer needs, effectively managing a variety of substances such as water, oils, and emulsions.
