Unique Spiral Groove Technology
The Type HX-J285 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 John Crane 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
●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 Type HX-J285 to seal all of the common industrial liquid gasses including oxygen, nitrogen and argon.
●The Type HX-J285 is more tolerant to system upsets and increases your mean time between pump maintenance.
