FEATURES:
• Dry running mechanical seal rotates with the shaft, providing for a vacuum and pressure-tight seal.
• Unlike conventional PTFE bearings, Chemglass’ mechanical seal stir bearing will not “flake”, contaminating your reaction.
• All seals are made using perfluorinated o-rings providing
outstanding resistance to the most aggressive chemicals.
• Bearing seals are rated up to 2,000rpm* with the seal life being
3,000 hours.
*Max RPM will depend on shaft and/or agitator type, along with alignment of motor and coupling. Chemglass recommends a max of 500rpm with used with any glass vessel, lid or shaft. Longer length stirrer shafts are required for use with CG-2077-M mechanical seal stir bearings.
