Type 8600 high duty seal range is available in single and dual arrangements for the most extreme pressures and speeds. Unique patented seal face design ensures stable and predictable operation across a wide pressure range, including resistance to high reverse pressure scenarios. Ideally suited for pipeline and injection duties. Can be supplied to international standards such as NACE MR-01-075.

Type 1648, 2648 and 3648 are API 682, 4th edition qualified Family A seals for use in general petroleum services. These are dependable, engineered mechanical seals developed typically to control emissions of light hydrocarbons and VOCs to less than 1,000 ppm. Type 1648 is a single cartridge seal designed to provide low emissions/leakage for most refinery applications. Type 2648 is a dual unpressurized cartridge seal designed to provide additional safety for hazardous applications and those where the sealing environment needs to be controlled. Type 3648 is a dual pressurized cartridge seal designed for maximum containment of hazardous fluids and light hydrocarbons. The inboard seal is double balanced to provide a positive A seal with pressure from either direction.

Type 8648VRS is a standardized non-pusher elastomer mechanical seal which uses unique secondary seal technology, designed specifically for difficult crude oil pipeline applications, with a focus on meeting the demanding requirements of pipeline pumping station duties.
