RS-81 & RS-81T Technical Data

The RS-81 & RS-81T (thin cross section) unbalanced shaft seals are designed for a wide range of process services. O-ring seals come in a variety of materials for handling various types of fluids, including corrosive liquids.

The positive drive from the shaft to the primary sealing ring face protects seals from damage due to slippage and prevents shaft galling. Precision lapped sealing faces provide reliable performance. The thin cross section RS-81T meets ANSI and other pump requirements for limited seal cavity dimensions.

The RS-81 and RS-81T are geometrically and dimensionally equivalent to competitive style seals.

Applications
The RS-81 and RS-81T (this cross-section) come in sizes to fit all types of rotary shaft equipment from centrifugal and rotary pumps, to mixers, agitators and autoclaves.
