Type 8648VRS
Garniture en élastomère sans ressort
8648VRS is a standardized non-pusher elastomer mechanical seal using patented technology, designed specifically for difficult hydrocarbon oil pipeline applications. It is designed specifically with a focus on meeting the demanding requirements of pipeline pumping station duties. Available as a single, dual pressurized or dual unpressurized arrangement, without outboard seals also incorporating the same non-pusher technology, the seal can be configured to suit both the operator and pipeline needs.

Caractéristiques
- California Residents: PROPOSITION 65 WARNING
- Unique patented secondary seal technology prevents wear to the sealing diameter and prevents secondary seal hang up
- Non-compressible flexible elastomer bellows avoids fretting under pump shuttling
- Robust Ear drive — primary ring incorporates optimized ear drive design for increased drive torque capability
- Balanced design – balanced construction, including anti-extrusion ring, permits use in the most demanding high-pressure pipeline duties
- Rotating mating ring design — enhances cooling and permits use at higher shaft speeds
- Premium seal face materials — permits sealing of difficult services at high operating pressures
- High-shore elastomer for lack of deformation and robust construction
- Axially compact and easy to install seal head assembly
- Static reverse pressure capability on the inboard seal of the dual pressurized configuration
- Laser face grooved mating ring for use on flashing hydrocarbons
