The NASH EnduraSeal eliminates traditional packing leakage at a lower cost than mechanical seals and includes a load assist feature that provides temporary shaft support in the unlikely event of bearing failure, thereby reducing the likelihood of a catastrophic failure. Available exclusively from Gardner Denver Nash, the EnduraSeal is an upgrade for NASH CL2000 - CL14000 and 904L - 904U liquid ring vacuum pumps.
Constructed of a proprietary polymer sleeve, the EnduraSeal offers a cleaner, more reliable operation by replacing traditional stuffing box packing. The sleeve offers additional shaft support in the unlikely event of bearing failure and enhances the support during high load conditions associated with process upsets.
Benefits of the EnduraSeal upgrade include:
• Reduced shaft leakage found with traditional packing • Reduced water migration to the bearing housing • Reduced environmental and housekeeping issues associated with shaft leakage • Proprietary sleeve provides supplemental running time if primary bearing fails • No grease required
