Product Description:
These premium replacement diaphragms are specially engineered for QBY/K series pneumatic diaphragm pumps. Crafted from robust elastomers and engineered plastics, they offer reliable performance and durability for various pumping needs.
Customers can choose from three distinct material options to suit different application requirements. The NBR (nitrile rubber) variant is suitable for general-purpose use involving oil and water. The F46 diaphragm, made from modified PTFE fluoropolymer, is designed to handle aggressive chemical substances. For applications demanding maximum chemical resistance and high purity, the imported PTFE (polytetrafluoroethylene) version is available.
These diaphragms are manufactured in a range of outer diameters, spanning from 140 mm to 450 mm. They come with standard bolt hole patterns, such as the 10-hole configuration, as well as plain-edge versions to accommodate various pump models. Each diaphragm undergoes precision molding to guarantee a perfect seal, extended flex life, and reliable pumping performance, even in the most demanding industrial environments.
Ideal for replacing worn or damaged diaphragms, these components are perfectly suited for use in slurry pumps, chemical transfer systems, food processing equipment, and mining operations. Their robust construction ensures consistent operation and reduced downtime across diverse industrial applications.
Features:
Material Options
NBR (Nitrile) is a highly durable material known for its 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, a type of fluoropolymer, offers outstanding chemical resistance, especially against acids, solvents, and strong oxidizers. This material performs reliably between -20°C and +150°C, ensuring versatility in harsh chemical settings.
Imported PTFE features a superior non-stick surface and is inert to nearly all chemicals. Its properties make it an ideal choice for applications in food and pharmaceutical industries, where hygiene and chemical inertness are critical.
Product Specifications
The products are available in diameters ranging from 140 mm up to 450 mm, providing compatibility with a wide variety of pump models.
Regarding bolt hole configurations, options include a standard 10-hole pattern for larger sizes, as well as plain-edge versions without holes designed for clamp-style mounting.
Performance and Compatibility
These materials and designs boast high flexural fatigue resistance, allowing them to endure millions of cycles without cracking, thus ensuring long-term reliability.
Precision molding techniques guarantee an accurate fit and effective sealing against pump housings, minimizing leakage and enhancing operational efficiency.
The components are interchangeable and serve as direct replacements for QBY/K10-15, K25-40, K50-65, and K80-100 series pumps, simplifying maintenance and part sourcing.
Additional Benefits
Cost-effectiveness is achieved through extended pump service life and reduced downtime, offering economic advantages to users.
Furthermore, color-coded options such as blue polyether (polyurethane) variants are available for special applications, including enhanced abrasion resistance.

Applications:
The transfer and dosing of various chemicals such as acids, caustics, and solvents are essential processes in many industrial settings. These operations require precise handling to ensure safety and efficiency.
Circulation systems for paints, inks, and coatings play a crucial role in maintaining consistency and quality in manufacturing processes. Proper circulation ensures uniform distribution and stability of these materials.
In the mining and mineral processing industries, the handling of slurries and muds is a critical task. Efficient transfer systems help in managing abrasive and dense mixtures that are common in these environments.
The food and beverage sector demands materials that comply with PTFE and FDA standards to guarantee product safety. Pumps and transfer equipment designed with these compliant materials ensure hygienic processing conditions.
Treatment of wastewater and effluents involves the careful management of various fluids. Effective pumping solutions assist in environmental protection by facilitating proper treatment and disposal.
The petroleum industry requires reliable transfer systems for fuels and related petroleum products. These systems must withstand harsh conditions and maintain integrity to prevent leaks and contamination.
Pumping ceramics and glazes is a specialized application requiring equipment able to handle viscous and abrasive fluids without compromising product quality.
Pharmaceutical and bioprocess industries depend on sanitary and precise fluid handling solutions. Equipment used in these sectors must meet stringent regulatory standards to ensure product purity and process reliability.
Finally, general industrial fluid transfer covers a wide range of applications involving water, oils, and emulsions. Versatile pumping solutions are needed to accommodate the diverse properties of these fluids.
