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.
The main risk of seal failure in these applications is due to the numerous problems associated with the secondary dynamic O-ring, potentially resulting in hang up, fretting or stub sleeve wear. The design of the 8648VRS completely eliminates these common problems.
By allowing operation without the potential for secondary seal problems, the 8648VRS provides longevity and reliability even in the most difficult pipeline applications.
