TYPE 8648VRS NON-PUSHER ELASTOMER LIQUID HYDROCARBON PIPELINE SEAL Unique patented NPSS technology prevents wear to the sealing diameter and prevents secondary seal hang-up Available as a single, dual pressuized or non pressurized seal arrangement Balanced design and construction, including anti-extrusion ring, permitting use on higher pressure pipelines Rotating mating ring design enhances cooling and permits use at higher shaft speeds Long distance hydrocarbon pipeline operations with multiple, unmanned and remote pumping stations, means that in certain regions, many pipeline pumps rely on single mechanical seals to prevent leakage. The Type 8648VRS, non-pusher elastomer mechanical seal is now available for crude oil and light hydrocarbon pipeline applications such as ‘products’ and ‘NGLs’. Where a single seal is not suitable, John Crane now offers the Type 8648VRS in either a dual pressurized or non pressurized arrangement with a whole range of NPSS enabled seals. Optimized technical solutions for difficult liquid hydrocarbon pipeline applica

TYPE 8648VRS NON-PUSHER ELASTOMER SEAL FOR CRUDE OIL, FLASHING AND NON FLASHING HYDROCARBONS The Type 8648VRS now enables pipeline operators transporting crude oil, non flashing hydrocarbons such as gasoline and diesel, and flashing hydrocarbons such propane and butane to increase the reliability and operational uptime for between-bearing pumps, so significantly reducing operational costs. By allowing operation without the potential for secondary seal problems the 8648VRS provides longevity and reliability even in the most difficult hydrocarbon pipeline applications. Additionally, it...
