Features mechanical seal type 285

  • 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.

Features mechanical seal type 285

  • The design and materials of construction meet the industry safety requirements, allowing the Type 285 to seal all of the common industrial liquid gasses including oxygen, nitrogen and argon.
  • The Type 285 is more tolerant to system upsets and increases your mean time between pump maintenance.

About Mechanical seal type 285

Process pumps Other rotating equipment With its proven track record of exceptional performance, the Type 1 elastomer bellows seal is widely recognized as the industry’s workhorse. Suitable for a wide range of service conditions ranging from water and steam to chemicals and corrosive materials, the Type 1 mechanical seal is ideal for use in pumps, mixers, blenders, agitators, air compressors, blowers, fans and other rotary shaft equipment.

It is frequently used by the pulp and paper, petrochemical, food processing, wastewater treatment, chemical processing and power generation industries.
