Robust low temperature edge-welded metal bellows seals. Available in various metallurgy including alloy C-276 in Type 670 for corrosive applications.

Type 285 seal is the first noncontacting, specially designed welded metal bellows seal to be applied to the toughest cryogenic applications. Type 285’s compact design fits the most popular cryogenic pumps without modification: both site-based and road tanker pumps. It is available in various seal cartridge arrangements: flanged and left- or right-hand threaded. The design and construction material meet the industry，safety requirements, allowing.Type 285 to seal common industrial liquid gases including oxygen, nitrogen and argon.

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.

Type 3740 Series is a fully split, outside-mounted, balanced, ODpressurized, O-ring pusher seal designed for use on pumps, mixers, agitators and various other equipment. A fully split design allows installation or repair of the seal without disassembly of the equipment. The incorporation of preassembled rotating and stationary sub-assembly halves simplifies installation.

Type 37FS and 37FSB (balanced) fully split seals provide easy mounting and reduced maintenance downtime for sealing equipment. Type 37FS is recommended primarily for use in heavy duty equipment and equipment with vibration or axial run-out. Type 37FSB is recommended for higher pressure applications.
