Depac - Model Type 191 -Stationary, Balanced Mechanical Seal
FromDepac
The type 191 is a stationary, balanced mechanical seal for use as an alternative to packings. The stationary design makes a longer service life possible on account of the lower face friction. A mechanical seal with which critical areas of application - for example, hot water or media containing abrasive solids - can be sealed easily and inexpensively.
