| Your choices are... | |||
| Adjustable Dampener | Dampener can be field modified or tuned to accommodate differing pressure ranges and response rates. | ||
| Automatic Dampener | A valve located in the non-wetted section of the dampener allows for an increase in compressed air pressure to balance an increase in system liquid pressure. As liquid system pressure increases a contact opens the valve and allows compressed air to enter the dampener. | ||
| Chargeable Dampener | The chamber within the dampener is charged with compressed air or nitrogen gas to create a cushion to absorb pressure pulses within the system. | ||
| Liquid Filled Dampener | Fluid within the cavity is used to smooth the system. | ||
| Suction Lift Dampener | A suction lift or stabilizer is mounted on the inlet side of a pump to reduce acceleration head and ensure that the pump is feed evenly. | ||
| Pressure Snubber | Pressure snubbers are devices located before a pressure gauge to guard the gauge against pulsations in the measured media. | ||
| Other | Other unlisted, specialized, or proprietary dampener. | ||

Trade names include Breon® (BP Chemicals), Chemigum® (Goodyear), Hycar® (B F Goodrich), Krynac® (Polysar Ltd.), Nipol® (Zeon Chemicals), Nysyn® NBR, (DSM Elastomers), Paracril® (Uniroyal Chemical), and Perbunan® (Mobay). | ||
| EPDM | Ethylene propylene (EPDM) offers good resistance to sunlight, weathering and ozone. It has poor resistance to petroleum oils and fuel. Good heat and compression set resistance. Suggested operating temperature (-70° to 275° F). Trade names include Nordel® (Dupont Dow Elastomers), Vistalon® (Exxon Mobil Chemical), Epsyn® (DSM Elastomers), Royalene® (Uniroyal Chemical), and Epcar® (B.F. Goodrich). | ||
| Hypalon® (CSM) | Chlorosulfonated polyethylene (CSM) provides excellent ozone, oxidation, sunlight (color degradation), and weather resistance. They are also capable of providing resistance to alkalis and acids. Suggested operating temperature (-60° to 300° F). Hypalon® is a registered trademark of DuPont Dow Elastomers. | ||
| Neoprene | A synthetic rubber that resists degradation from sun, ozone, and weather. It performs well in contact with oils and many chemicals. Neoprene remains useful over a wide temperature range, displays outstanding physical toughness, and resists burning inherently better than exclusively hydrocarbon rubbers. Neoprene also offers resistance to damage caused by flexing and twisting. Suggested operating temperature (-45° to 230° F). DuPont Dow originally engineered neoprene. | ||
| PVC | Polyvinyl chloride (PVC) is a widely used material that has good flexibility, smooth surface, and nontoxic qualities. Some grades are used in food and chemical processes due to the inert nature of PVC. Brand names include: ACP® and Dural® (Alpha Gary), Geon® (Geon), Benvic® (Solvay), Flexalloy® (Teknor Apex). | ||
| PTFE | Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers. | ||
| Santoprene® | Santoprene® thermoplastic rubber is a series of high-performance elastomers that combine the characteristics of vulcanized rubber, such as flexibility and low compression set, with the processing ease of thermoplastics. Santoprene provides oil and heat resistance. Santoprene is a registered trademark of Advanced Elastomer Systems. | ||
| Silicone | Silicones are polymers in which organics groups, such as methyl and phenyl groups are bonded to the silicone atoms in chains of inorganic siloxanes (-Si-O-Si-). Their properties include heat, cold and weather resistance, electrical insulation, release, water repellency and defoaming. | ||
| Viton® | A range of fluoropolymer elastomers whose formulation can be tailored to a reasonable extent to meet the needs of individual end-uses. They are normally black and have high heat, oil and chemical resistance but indifferent low temperature performance. With the exception of Kalrez® (Dow DuPont Elastomers) perfluorinated elastomer, they are about the most highly temperature resistant of all commercially available elastomers. Viton® is a registered trademark of DuPont Dow Elastomers. | ||

| Cast Iron | The term "cast iron" refers not to a single material, but to a family of materials whose major constituent is iron, with important trace amounts of carbon and silicon. Cast irons are natural composite materials whose properties are determined by their microstructures - the stable and metastable phases formed during solidification or subsequent heat treatment. The major microstructural constituents of cast irons are: the chemical and morphological forms taken by carbon, and the continuous metal matrix in which the carbon and/or carbide are dispersed. | ||

| PVDF | Polyvinylidene fluoride (PVDF) is a melt processable fluoropolymer. It is similar in properties to other fluoropolymer, but has better strength and lower creep than the other members of this family. PVDF has good wear resistance, and excellent chemical resistance. But does not perform well at elevated temperatures. Brand names include: Kynar® (Elf AtoChem). | ||
| PTFE | Polytetrafluoroethylene (PTFE) is an insoluble compound that exhibits a high degree of chemical resistance and a low coefficient of friction. It is sometimes marketed in proprietary classes of materials such as Teflon®, a registered trademark of DuPont Dow Elastomers. | ||
