UST
The UST is a general purpose mechanical seal. It is designed to work with water solutions, not very aggressive chemicals and other liquids contaminated with particulate solids.
V
It is a general purpose mechanical seal with a wide range of applications for clean media. It is designed for use with petrochemicals, not very aggressive chemicals and refrigerants.
VB
It is a general purpose mechanical seal with a wide range of applications for clean media. It is designed for use with petrochemicals, not very aggressive chemicals and refrigerants.
VBT
It is a general purpose mechanical seal with a wide range of applications and increased chemical resistance (PTFE secondary seal). It is designed for use with petrochemicals, not very aggressive chemicals and refrigerants.
VD
It is a general purpose mechanical seal with a wide range of applications. These seals are reliably operated in media which do not form lubricating films, and in toxic, flammable and explosive media. Use of the barrier liquid system assures seal lubrication and cooling, and prevents deposit formation on the seal sliding surfaces, to increase its reliability and durability.
VS
It is a general purpose mechanical seal with a wide range of applications for clean media. It is designed for use with petrochemicals, not very aggressive chemicals and refrigerants.
VSK
It is a general purpose mechanical seal with a wide range of applications for clean media and those containing small amounts of abrasives. It is designed for use with petrochemicals, not very aggressive chemicals and refrigerants.
VT
It is a general purpose mechanical seal with a wide range of applications and increased chemical resistance (PTFE secondary seal). It is designed for use with petrochemicals, not very aggressive chemicals and refrigerants.
W
It is an outside mounted mechanical seal. It is designed to operate with not very aggressive chemicals and liquids contaminated with solid particles. Used in impeller pumps in the chemical industry, waste water treatment plants, pulp & paper mills and sugar factories.
