Product Description:
The BSK series pump diaphragms serve as premium replacement membranes specifically engineered 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 provide exceptional chemical resistance, a long flex life, and dependable sealing performance, even in the most demanding industrial environments.
Santoprene is a high-performance thermoplastic elastomer produced by cross-linking EPDM rubber with polypropylene. This unique combination offers the flexibility and elasticity typical of rubber alongside the strength and processability of thermoplastics. Santoprene diaphragms are commonly utilized in fluid-handling systems due to their durability, abrasion resistance, and wide-ranging chemical compatibility. They are available in both beige and blue colors and demonstrate excellent resistance to acids, caustic substances, and abrasive fluids.
PTFE, also known as polytetrafluoroethylene or Teflon, is recognized as the most chemically inert synthetic compound. Diaphragms made from PTFE exhibit outstanding corrosion resistance, capable of enduring exposure to aggressive chemicals and temperatures reaching up to +260°C. Their near-universal chemical compatibility spans the entire pH scale from 0 to 14, making PTFE diaphragms the perfect solution for handling corrosive, hazardous, or high-purity fluids.
Whether utilized as original equipment manufacturer (OEM) replacements or during routine maintenance, BSK series pump diaphragms ensure the precision, reliability, and durability necessary for critical industrial fluid handling applications.
Features:
Premium Material Options
Our diaphragms are available in high-quality Santoprene and PTFE (Teflon) materials to meet a variety of application needs. Santoprene options come in beige and blue colors, allowing for easy identification and selection.
Santoprene Diaphragms
Santoprene diaphragms combine the elasticity of rubber with the durability of thermoplastics. They offer outstanding abrasion resistance, an extended flex life, and are compatible with a wide range of chemicals.
PTFE Diaphragms
PTFE diaphragms provide nearly universal chemical resistance, handling substances across a pH range from 0 to 14. They are capable of withstanding aggressive chemicals and can tolerate temperatures as high as 260°C.
Performance and Durability
Engineered for longevity, our diaphragms deliver superior flex life, capable of enduring millions of strokes in high-cycling environments. The Santoprene material resists acids, caustic substances, and abrasive fluids, while PTFE is inert to almost all chemicals except molten alkali metals and elemental fluorine.
