Product Description:
The Skylink SK Series pump diaphragms are premium replacement membranes crafted specifically for Skylink SK Series air-operated double diaphragm pumps. These diaphragms are compatible with models SK15, SK25, SK40, SK50, and SK80. Manufactured using high-quality materials such as Blue Santoprene, PTFE (Teflon), and NBR (Buna-N), they deliver superior chemical resistance, extended flex life, and dependable sealing performance even under the most challenging industrial conditions.
Santoprene is a high-performance thermoplastic elastomer that blends the flexibility and elasticity of rubber with the toughness and manufacturability of thermoplastics. The blue version boasts excellent abrasion resistance, wide chemical compatibility, and a long flex cycle life, making it well-suited for handling abrasive slurries and moderate chemical environments. It operates efficiently within a temperature range from -40°C to +130°C. PTFE, also known as Teflon, stands out as the most chemically inert material, offering virtually universal resistance to chemicals across a pH spectrum of 0 to 14. It withstands aggressive substances and high temperatures, up to +260°C. NBR, or Buna-N, provides excellent elasticity, robust oil resistance, wear durability, and mechanical resilience against solid and abrasive particles, making it ideal for general-purpose uses involving oils, water, and mild chemicals.
Skylink diaphragms are constructed with durability and adaptability in mind, using top-tier materials to handle a variety of fluid types. Whether employed as original equipment manufacturer (OEM) replacements or for regular maintenance routines, Skylink SK Series pump diaphragms ensure precision, reliability, and longevity that are essential in critical industrial fluid management applications. Additionally, components such as the air motor, diaphragm, valve ball, and pilot valve are designed for in-line servicing and replacement, enhancing maintenance convenience and uptime.
Features:
Our premium diaphragm materials are available in Blue Santoprene, PTFE (Teflon), and NBR (Buna-N), each tailored to meet specific application demands. This variety ensures optimal performance across diverse industrial scenarios.
The Blue Santoprene diaphragms combine the elasticity of rubber with the durability of thermoplastics. They exhibit excellent resistance to abrasion, boast a long flex life, and can tolerate a wide range of chemicals. These diaphragms operate efficiently within a temperature range from -40°C up to +130°C.
PTFE diaphragms stand out for their nearly universal chemical resistance, effectively handling substances across a pH range of 0 to 14. They are capable of withstanding aggressive chemicals and can operate reliably at elevated temperatures reaching +260°C.
For general-purpose applications, NBR (Buna-N) diaphragms offer exceptional elasticity alongside good resistance to oils, wear, and mechanical stress caused by solids and abrasive particles. This makes them suitable for a variety of demanding environments.
Engineered for exceptional durability, these diaphragms deliver a superior flex life, capable of enduring millions of cycles in high-frequency use. They come in a wide size range, from 1/2" (140mm) to 3" (400mm), ensuring compatibility with various pump models.
The construction is designed for longevity, making them reliable components within harsh industrial settings. Each diaphragm is manufactured to precise specifications to ensure a perfect fit for Skylink pumps, including models SK15, SK25, SK40, SK50, and SK80.
Maintenance is straightforward and efficient; critical parts such as the air motor, diaphragm, valve ball, and pilot valve can be serviced or replaced directly online. Additionally, these diaphragms require no air lubrication, which lowers upkeep costs and simplifies operational procedures.
