Features Type 10T
- California Residents: PROPOSITION 65 WARNING
- A shaft-mounted seal that has all wetted components made from PTFE for high corrosion resistance.
- Seal is mounted outside of the stuffing box.
Recommended Applications Type 10T
- Process pumps
Design Features Type 10T
- Non-pusher bellows feature eliminates sliding contact with the equipment shaft or sleeve during operation
- The outer-end of the seal bellows is clamped to the shaft or sleeve surface, and the bellows convolutions extend to compensate for seal face wear
- All surfaces contacting the liquid being sealed are made of chemically inert materials. Metallic components — springs and clamping ring — are located outside the pump stuffing box, isolated from the process liquid
- The Type 10T face is not replaceable, but the seal has a higher-duty pressure and transient pressure rating than the Type 10R
- The Type 10R seal face is replaceable and can be supplied in hard materials making the seal suitable for abrasive applications
- The seals incorporate visual wear indicators which show the initial seal setting and the amount of face wear while in service
