- Material Composition:
- Elastomeric Compounds: Available in various compounds tailored to specific applications:
- Natural Rubber (NR/SBR): Offers excellent dynamic properties for general-purpose applications, operational within a temperature range of -40°C to +70°C.
- Nitrile Rubber (NBR): Provides superior resistance to oils, fuels, and outdoor conditions, functional from -25°C to +110°C.
- Ethylene Propylene Diene Monomer (EPDM): Excellent for high-temperature environments with outstanding resistance to ozone and weathering, operational from -20°C to +115°C.
- Chloroprene Rubber (CR): Balances good weather resistance with moderate oil resistance, suitable for temperatures ranging from -20°C to +110°C.
- Elastomeric Compounds: Available in various compounds tailored to specific applications:
- Reinforcement Layers: The D Series air bellows feature multiple fabric plies integrated between the inner and outer rubber layers, providing enhanced durability and allowing the bellows to withstand higher pressures and dynamic loads.
- End Closures: The D Series bellows are available with various closure types for easy integration into different systems:
- Standard Bead Ring Design: Facilitates straightforward assembly to machinery.
- Enhanced Closure Designs: Available for applications requiring higher pressure and load capacities, ensuring secure and stable installation.
- Metallic Components: Standard metallic parts are manufactured from electro-galvanized steel, offering corrosion resistance. For environments with aggressive chemicals or high corrosion potential, stainless steel options (AISI-304 or AISI-316L) are available.
