Type DS-GNZ mechanical seal is designed for media containing solids or with high viscosity e.g. sugar, paper, sewage, and waste water industry. The wave springs are product protected. There is no sticking or clogging making the design rugged and reliable.

Applications

 For use in pumps, mixers, blenders, agitators, compressors and other rotary shaft equipment.

 For pulp and paper, petrochemical, food processing, wastewater treatment and other demanding apllications.

Operating Conditions

•  Max. Operating Pressure : 25 kg/cm2 *

•  Temperature Range : -15 to 200 *

•  Max. Rubbing Speed : 20 m/s

*(Depend on combination of materials)

Design Features/Benefits

  The wave spring designed for install in the shallow seal chamber.

 Independent of shaft rotating direction.

 Springs are isolated from liquid rich in solid impurity.

 Setting-length of spring can be held in position by build in set-ring.
