QBY80-100 NBR&F46&PTFE Chemical Processing Pulse Valve Diaphragm Outer Diameter 400mm To 450mm Temperature 100°C

Product Description:

These premium replacement diaphragms are engineered specifically for QBY/K series pneumatic diaphragm pumps. Constructed from high-quality elastomers and engineering plastics, they ensure durability and reliable performance.

Customers can choose from three different material options to suit various applications. The NBR (nitrile rubber) variant is suitable for general-purpose use involving oil and water. For handling aggressive chemicals, the F46 material, a modified PTFE fluoropolymer, is an excellent choice. Additionally, imported PTFE (polytetrafluoroethylene) diaphragms offer superior chemical resistance and meet stringent high-purity standards.

The diaphragms are available in multiple outer diameters, ranging from 140 mm to 450 mm. They come with standard bolt hole patterns, such as the 10-hole configuration, or as plain-edge versions to fit different pump models. Each diaphragm undergoes precision molding to guarantee an optimal seal, extended flex life, and stable pumping efficiency, even in the most demanding industrial conditions.

These replacement diaphragms are ideal for restoring the performance of worn or damaged components in slurry, chemical, food, and mining transfer pumps, helping maintain smooth and reliable pump operation.

Features:

The available materials cater to a range of application needs. NBR (Nitrile) offers excellent resistance to oil, fuel, and water, performing reliably within a temperature span from -30°C to +100°C. For environments requiring higher chemical resistance, F46 (Fluoropolymer) stands out due to its outstanding ability to withstand acids, solvents, and strong oxidizers, with a broader temperature range of -20°C to +150°C.

Another option is Imported PTFE , which features a superior non-stick surface and remains inert to nearly all chemicals. This makes it particularly suitable for use in food and pharmaceutical applications, ensuring safety and hygiene.

The product is available in diameters ranging from 140 mm up to 450 mm, making it compatible with various pump models. Regarding mounting options, it comes with a standard 10-hole bolt pattern for larger sizes, while a plain-edge design without holes is provided for clamp-style mounting systems.

These materials boast high flexural fatigue resistance, engineered to withstand millions of cycles without developing cracks. The precision molding process ensures an accurate fit and reliable sealing against pump housings, contributing to improved performance and longevity.

The components are directly interchangeable with models such as QBY/K10-15, K25-40, K50-65, and K80-100 series pumps. This compatibility, coupled with their durable construction, leads to extended pump service life and a reduction in downtime, thus providing a cost-effective solution.

For specific applications requiring enhanced abrasion resistance, blue polyether (polyurethane) options are available. These color-coded materials help users quickly identify parts designed for special purposes.
