QBY50-65 NBR&F46&PTFE Chemical Processing Pulse Valve Diaphragm Outer Diameter 300mm To 340mm

Product Description:

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

Customers can choose from three distinct material options based on their operational needs. The NBR (nitrile rubber) variant is suitable for general-purpose uses involving oil and water. For handling aggressive chemicals, the F46 (modified PTFE/fluoropolymer) option provides enhanced chemical resistance. Additionally, an imported PTFE (polytetrafluoroethylene) version is available for situations demanding maximum chemical resistance and high purity standards.

The diaphragms come in a variety of 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 designs to accommodate different pump models. Each diaphragm is precision-molded to achieve excellent sealing capabilities, extended flex life, and consistent pumping efficiency, even in challenging industrial conditions.

These replacement diaphragms are ideal for servicing slurry, chemical, food, and mining transfer pumps. They provide a dependable solution for replacing worn or damaged diaphragms, helping to maintain optimal pump functionality and extend equipment lifespan.

Features:

NBR (Nitrile): This material offers excellent resistance to oil, fuel, and water. It operates efficiently within a temperature range from -30°C to +100°C, making it suitable for many industrial applications.

F46 (Fluoropolymer): Known for its outstanding chemical resistance, F46 can withstand exposure to acids, solvents, and strong oxidizers. It performs well in temperatures ranging from -20°C to +150°C.

Imported PTFE: With a superior non-stick surface, imported PTFE is inert to nearly all chemicals. This makes it especially suitable for food and pharmaceutical applications where hygiene and chemical inertness are crucial.

The product is available in a diameter range from 140 mm up to 450 mm, which fits various pump models. For mounting, it comes with either a standard 10-hole bolt pattern for larger sizes or a plain edge without holes for clamp-style attachment.

Engineered for durability, the material exhibits high flexural fatigue resistance, allowing for millions of cycles without cracking. The precision molding process ensures an accurate fit and reliable sealing against pump housings.

This component is designed to be interchangeable as a direct replacement for QBY/K10-15, K25-40, K50-65, and K80-100 series pumps. Additionally, it is a cost-effective solution that helps extend the service life of pumps and reduces downtime.

For special applications, such as enhanced abrasion resistance, blue polyether (polyurethane) options are available and clearly color-coded for easy identification.

Technical Parameters:

This Pulse Valve Diaphragm is an essential component in diaphragm repair kits and diaphragm repair accessories, making it ideal for use in a pulse valve repair kit to ensure optimal performance and durability.

Applications:

Chemical transfer and precise dosing are essential in many industries, involving substances such as acids, caustics, and various solvents. These processes ensure safe and accurate handling of potentially hazardous materials.

In addition, the circulation of paints, inks, and coatings plays a crucial role in maintaining consistency and quality during manufacturing operations. Effective pumping systems are used to keep these materials in motion and ready for application.

Handling slurries and muds is commonly required in the mining and mineral processing sectors. Specialized equipment is designed to manage these dense and abrasive mixtures efficiently.

The food and beverage industry demands equipment made with PTFE and FDA-compliant materials to guarantee hygiene and safety. These materials are vital for processing consumables while adhering to strict regulatory standards.

Wastewater and effluent treatment processes rely on robust fluid transfer systems to manage and treat liquids before they are released or recycled. These systems help to protect the environment and comply with legal requirements.

Transferring petroleum products and fuels requires pumps that can safely handle flammable and volatile liquids. The design considerations focus on safety, reliability, and preventing leaks or contamination.

Ceramic manufacturing and glaze application involve pumping systems that handle thick, viscous fluids. These systems ensure smooth delivery and uniform coating results for high-quality finished products.

The pharmaceutical and bioprocessing industries depend on sanitary and precise fluid transfer equipment. These systems support the manufacture of medicines and biologics with strict control over contamination and dosing accuracy.

Finally, general industrial fluid transfer covers a wide range of liquids such as water, oils, and emulsions. Versatile pumping solutions are utilized across multiple sectors to move these fluids efficiently and reliably.

Support and Services:

Our Pulse Valve Diaphragm is designed for durability and reliable performance in demanding industrial environments. To ensure optimal operation, regular inspection and maintenance of the diaphragm are recommended. Replace the diaphragm if any signs of wear, cracking, or deformation are observed.

When installing the diaphragm, make sure the sealing surfaces are clean and free from debris. Proper alignment is crucial to prevent air leakage and ensure efficient pulse valve operation. Use compatible lubricants if specified, avoiding any substances that may degrade the diaphragm material.

If you encounter any operational issues such as inconsistent pulsing or air leakage, check the diaphragm for damage and verify that all valve components are correctly assembled. For troubleshooting guidance, refer to the product manual or technical datasheet provided with the valve.

We offer comprehensive technical support to assist with installation, maintenance, and troubleshooting. Our team can provide detailed instructions and recommendations tailored to your specific application requirements.

For replacement parts and servicing, ensure that only genuine Pulse Valve Diaphragms are used to maintain product integrity and warranty coverage. Proper storage of spare diaphragms in a cool, dry place away from direct sunlight will help preserve their material properties.

Packing and Shipping:

Product Packaging and Shipping for Pulse Valve Diaphragm

The Pulse Valve Diaphragm is carefully packaged to ensure safe delivery and maintain product integrity. Each diaphragm is individually wrapped in protective material to prevent damage during transit. The wrapped diaphragms are then placed in sturdy, cushioned boxes designed to absorb shocks and vibrations.

For bulk orders, the diaphragms are organized systematically within larger cartons, with adequate padding between items to avoid any abrasion or deformation. All packaging materials used are environmentally friendly and comply with international shipping standards.

Shipping options include air freight, sea freight, and express courier services, depending on customer requirements and destination. Each shipment is clearly labeled with product details, handling instructions, and tracking information to ensure timely and accurate delivery.

We recommend inspecting the packaging upon receipt to confirm that there is no visible damage. In case of any issues, please contact our customer service immediately for assistance.
