Type 5840 is a single cartridge seal that includes many of the advantages associated with heavy duty seal design assembled into a cost effective package for the volume requirements associated with general mineral processing duties. It is manufactured from materials resistant to abrasive and/or chemical attack, to provide long service life in hostile environments. The absence of dynamic secondary seals means that there is no shaft fretting or damage and no hang-up of primary seal faces.

Type HTC high-temperature,corrosion-resistant, welded metal bellows seal is a unique advanced technology for reliably sealing fluids in harsh high temperature corrosive environments. It also provides superior face stability at elevated temperatures. Available with double-ply bellows for higher pressure applications.

Non-contacting, nonelastomer dual gas seal for high temperature applications. API 682 qualified. Piping Plan 74 is used to supply an inert gas to the seal for zero emissions. The seal is pressure balanced to ensure full reverse pressure containment capability. Metal bellows technology with inert graphite stationary secondary seals.

Dry-running metal bellows seal used for emission containment and for safety/ back-up of the primary seal. Available in low and high temperature versions. It is supplied in the outboard position of a dual/tandem cartridge assembly.

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.
