GRACO Diaphragms for Double Diaphragm Pumps - Grainger Industrial Supply

316 Stainless Steel is more corrosion and abrasion resistant than cast iron and aluminum. 316 stainless steel is highly resistant to chemicals. It's suited for outdoor applications where it may be exposed to sunlight, rain, and debris that would damage plastic-based pumps.
Acetal is a durable plastic that resists abrasion better than most metals. Acetal is highly resistant to solvents and prevents static discharge from occurring during operation; however, these pumps should not be used in applications transferring bases or acids.
Buna-N is suited for handling petroleum liquids such as crude oil and natural gas, some solvents, and mildly corrosive chemicals.
Hytrel is highly abrasion resistant.
Neoprene is suited to handling petroleum, greases, and vegetable and animal-based oils. Neoprene can also be used in applications that manufacture alcoholic beverages such as beer and wine. It should not be used with oxidizing acids.
Polypropylene is a lightweight plastic that is compatible with a wide range of chemicals and can be easily transported in applications that require the pump to be relocated often.
PTFE (polytetrafluoroethylene) is highly resistant to chemicals. It is heat-resistant plastic with a low friction coefficient.
Santoprene is moderately resistant to chemicals, abrasives, and heat.
Viton is moderately resistant to corrosives and handles a narrow range of solvents. It can be used in applications involving animal, vegetable, and petroleum-based oils.
