Type 609 Metal Bellows Seals | John Crane Mechanical Seals

Type 609

Garnitures à soufflet métallique rotatifs haute température, à bords soudés

The Type 609 is a high-temperature (to 425°C/800°F) rotating seal head assembly that incorporates all of the rugged features of the Type 604, but is intended for those demanding applications where a dependable, high-strength, rotating seal is preferred. A narrow cross-section design enables the Type 609 to fit in the most popular pumps without expensive and time-consuming seal chamber modifications. This makes it the ideal seal for heat transfer, hydrocarbon and other applications that commonly use pumps with limited seal chamber clearances. Typical applications include hot hydrocarbons, aqueous solutions, aromatic fractionation products, crude oil fractionation products and heat transfer fluids.
