Low temperature seals
Y12, Y13, Y33, Y17, Y18, Y37
Features
- Rotating bellows seal
- Balanced
- No dynamic O-Ring, no hang-up, no shaft sleeve damage
- Uniform seal face loading
- Independent of direction of rotation
- Ideally suited for highly corrosive and abrasive media
- Compact design
Advantages
- Over 35 years of running reference in the field
- Narrow cross-section allows the seal fitment in narrow stuffing boxes
- Self cleaning, non-clogging design
- Cost effective solution for corrosive and abrasive media
- Long seal life
