Product Description:
The diaphragms in the BSK series are premium replacement membranes tailored specifically for use with BSK-25, BSK-40, BSK-50, and BSK-80 metering pumps. Crafted from high-quality materials such as Santoprene and PTFE (Teflon), these diaphragms ensure excellent chemical resistance, extended flex lifetime, and dependable sealing performance, even in the most demanding industrial environments.
Santoprene is a top-tier thermoplastic elastomer formed by cross-linking EPDM rubber with polypropylene. This unique combination provides the rubber-like flexibility and elasticity along with the robustness and ease of processing typical of thermoplastics. Due to its long flex life, abrasion resistance, and broad chemical compatibility, Santoprene diaphragms are extensively employed in fluid-handling systems. They come in beige and blue color options, delivering outstanding resistance against acids, caustic substances, and abrasive fluids.
PTFE, also known as Teflon and formally called polytetrafluoroethylene, stands as the most chemically inert synthetic material available. Diaphragms made from PTFE offer exceptional corrosion resistance and can endure exposure to aggressive chemicals and temperatures as high as +260°C. Their virtually universal compatibility with chemicals across the entire pH spectrum from 0 to 14 makes them an excellent choice for managing corrosive, hazardous, and ultra-pure media.
Whether utilized as original equipment manufacturer (OEM) replacements or during routine maintenance, BSK series pump diaphragms provide the precision, reliability, and durability essential for critical industrial fluid handling operations.
Features:
Our diaphragm options are crafted from premium materials, including Santoprene, available in beige and blue, as well as PTFE (Teflon), to meet a variety of application needs. These materials are selected to provide optimal performance and durability under different operating conditions.
Santoprene diaphragms offer a unique combination of rubber-like elasticity and the toughness of thermoplastics. This blend results in excellent abrasion resistance, an extended flex life, and a wide chemical tolerance, making them suitable for demanding environments.
On the other hand, PTFE diaphragms deliver almost universal chemical resistance, effectively handling substances across the entire pH spectrum from 0 to 14. They can endure exposure to aggressive chemicals and operate at temperatures as high as 260°C, ensuring reliability in harsh conditions.
Engineered for longevity, these diaphragms boast a superior flex life that supports millions of cycles, making them ideal for applications requiring high-frequency operation. Their durable construction guarantees a long service life even in the most challenging industrial settings.
Regarding chemical compatibility, Santoprene is resistant to acids, caustics, and abrasive fluids, while PTFE remains inert to nearly all chemicals except molten alkali metals and elemental fluorine. This versatility ensures that the right material can be chosen for your specific chemical environment.
Each diaphragm is manufactured with precision to perfectly fit BSK-25, BSK-40, BSK-50, and BSK-80 pump models. Additionally, the availability of multiple color options for Santoprene diaphragms—beige and blue—allows for easy identification and differentiation in various applications.
