RAM-GJ units are equipped standard with Viton™ O-rings, but for steam applications or special chemical processing two elastomer upgrades are available for special order:
- Viton™ – Type A Viton O-rings (Durometer 75) are standard on RAM-GJ units. Viton™ fluoroelastomer performs at a wide range of temperatures, with oil and chemical resistance being unaffected by elevated temperatures. It also provides resistance to degradation by a wide variety of fluids and chemicals, including excellent resistance to oils, fuels, lubricants, and most mineral acids.
- Aflas® – Aflas O-rings are suited for steam applications. TFE/P is a copolymer of tetrafluoroethylene and propylene with a fluorine content of approximately 54%. A unique material due to its resistance to petroleum products, steam, and phosphate-esters, TFE/P is ideal for heat transfer media, amines, acids and bases, as well as hot water and steam up to +170°C (+340°F). Service temperatures are (25°F) to +204°C (+400°F); The compression set resistance at high temperatures is inferior to standard fluorocarbons.
- Kalrez® – DuPont™ Kalrez® perfluoroelastomer (FFKM/FFPM) parts resist over 1,800 different chemicals, while offering the high temperature stability of PTFE (327°C). They’re used in highly aggressive chemical processing, semiconductor wafer fabrication, pharmaceutical, oil and gas recovery, and aerospace applications.
In addition to upgrading the seal elastomer, additional steps can be taken to protect your unit in demanding applications. pdblowers can coat the wetted components of your blower with Electrolysis Nickel, Armoloy® TDC, Gullon, or Gullite depending on your specific need.
