Gas-lubricated, Non-contacting Single Seal For Cryogenic Pumps IS285 Unique Spiral Groove Technology

As the worldwide leader in spiral groove technology, iseal is the first to utilize non-contacting seals in cryogenic applications. The is285 can safely seal the most common industrial liquid gasses, such as liquid nitrogen, oxygen, argon and carbon dioxide. It fits the most popular cryogenic pumps — site-based and road tanker pumps — and meets liquid oxygen (LOX) safety standards. The iseal spiral grooves enable the seal to operate on a gas film by gathering and compressing the vaporized liquid. As the gas is forced towards the closed groove ends, the pressure rises, which creates a cushion to separate the sealing faces. Since the seal faces do not contact, dry-running and face wear problems, which are associated with conventional contacting seals, are virtually eliminated.

Features is285

California Residents: PROPOSITION 65 WARNING
Specially designed stationary edge-welded metal bellows.
Available in flanged, right- and left-hand threaded designs or as a cartridge.
Meets liquid oxygen (LOX) safety standards.
Anti-spark sleeve and retaining ring.
Reduced power consumption with minimal product loss. Since the seal faces do not contact, dry-running and face wear problems, which are associated with conventional contacting seals, are virtually eliminated.
The design and materials of construction meet the industry safety requirements, allowing the is285 to seal all of the common industrial liquid gasses including oxygen, nitrogen and argon.
The is285 is more tolerant to system upsets and increases your mean time between pump maintenance.
