Chesterton’s 491 Rotary Seal was specifically designed to fit those pumps with dimensions governed by the DIN 24960 dimensional standard.
The compact component style 491 seal is a high quality device designed to fit the very small seal chambers commonly associated with pumps governed by these standards.
The 491 is designed to offer a vast performance improvement over conventional, single spring OEM seals.
- Easy-to-install sealing device
- Hydraulically balanced to reduce heat generation.
- Springs are isolated from the process fluid to prevent clogging.
- Will not fret shaft or sleeve
- The rotor and stator come as a pair eliminating the need to match units from separate inventory for installation.
