These premium replacement diaphragms are tailor-made for the QBY/K series pneumatic diaphragm pumps. Crafted from robust elastomers and high-grade engineering plastics, they ensure durability and reliable performance in various applications.
Customers can choose from three distinct material types to suit their specific needs: NBR (nitrile rubber), ideal for general oil and water use; F46 (a modified PTFE fluoropolymer), designed to handle aggressive chemical substances; and imported PTFE (polytetrafluoroethylene), which offers superior chemical resistance and meets strict high-purity standards.
These diaphragms are available in a variety of outer diameters, ranging between 140 mm and 450 mm. They feature standard bolt hole arrangements, such as the common 10-hole pattern, as well as versions with plain edges to accommodate different pump models.
Each diaphragm undergoes precision molding to guarantee an impeccable seal, extended flex life, and consistent pumping efficiency even under rigorous industrial conditions. They serve as excellent replacement parts for worn or damaged diaphragms in slurry, chemical, food processing, and mining transfer pumps.
Our products offer a variety of material choices to suit different operational needs. The NBR (Nitrile) material provides excellent resistance to oil, fuel, and water, and can operate efficiently within a temperature range of -30°C to +100°C.
For applications requiring superior chemical resistance, the F46 (Fluoropolymer) option is ideal. It offers outstanding resistance against acids, solvents, and strong oxidizers, functioning well between -20°C and +150°C.
We also supply imported PTFE, which boasts a superior non-stick surface and is inert to nearly all chemicals. This makes it especially suitable for food and pharmaceutical applications.
The diameter range of the components spans from 140 mm up to 450 mm, accommodating a wide variety of pump models. Additionally, the bolt hole configurations include a standard 10-hole pattern for larger sizes, or a plain-edge design without holes for clamp-style mounting.
Our materials are engineered for high flexural fatigue resistance, capable of withstanding millions of cycles without cracking. Precision molding ensures an accurate fit, providing reliable sealing against pump housings.
These parts are designed to be interchangeable as direct replacements for QBY/K10-15, K25-40, K50-65, and K80-100 series pumps.
The cost-effective design helps extend the service life of pumps while reducing downtime. For specialized applications requiring abrasion resistance, blue polyether (polyurethane) options are available, distinguished by color-coding.

Our products are utilized for the transfer and dosing of various chemicals, including acids, caustics, and solvents. This ensures precise handling of hazardous and reactive substances in different industrial environments.
They are widely used in the circulation of paints, inks, and coatings, providing efficient and consistent flow necessary for high-quality finishing processes.
In the mining and mineral processing sectors, these solutions facilitate the handling of slurries and muds, helping to manage abrasive and dense fluids effectively.
Food and beverage processing applications benefit from materials that comply with PTFE and FDA standards, ensuring safety and hygiene during fluid transfer operations.
The products also play a crucial role in wastewater and effluent treatment by enabling the controlled movement and dosing of treatment chemicals and fluids.
For the petroleum industry, these systems are ideal for transferring fuels and other petroleum-based products safely and efficiently.
Ceramic manufacturing and glaze pumping applications rely on these pumps to handle viscous and particulate-laden liquids with accuracy.
The pharmaceutical and bioprocess industries utilize these solutions to ensure sterile and precise fluid transfer, supporting complex manufacturing processes.
Finally, general industrial fluid transfer needs—such as moving water, oils, and emulsions—are met with reliable and adaptable pumping technology suitable for various applications.
