Cartridge Mechanical Shaft Seals
 |
Install these seals faster and with less technical expertise than other mechanical shaft seals that come in two pieces. They come with their seal and seat already assembled. All have a carbon washer that is self-lubricating. However, this means their washer is too soft to be used with abrasive liquids and liquids with harsh additives.
Fluoroelastomer Diaphragm—Seals with a fluoroelastomer diaphragm can be used with a wider range of chemicals than EPDM diaphragms, including benzene, butyl alcohol, and fuels.
EPDM Diaphragm—Seals with an EPDM diaphragm won’t break down from exposure to water and steam. However, they are for use with fewer chemicals.
