  • Applying Plan 74 with only N2 auxiliary system, and without a cooling system. Achieving a clean operating condition and environment. 
  • In coordination with the N2 auxiliary system, a stable and clean gas source can be maintained to achieve zero VOC leakage. 
  • No discarded lubricating oil or cooling fluid. Reduced consumption of oil & water resources. Obseved co-existence with the environment.
  • Non-contacting seal faces, minimized wearable materials, support equipments and maintence costs.  
  • Reduced cost, power and vibration due to the non-contacting seal faces. Required power consumption is just 10%~15% in compararison to wet seal. 
  • The patented cartridge design features innovative drop-proove springs, thereby speeding installation and maintenance.
  • Uncontaminated springs, less stress, no corrosion or hang-up condition.



  • High-purity, clean and pollution-free processes, such as pharmaceuticals, fermentation, chemistry, electronics, etc.
  • Process substances compatible with nitrogen.
  • Impurity-free, volatile and dry fluid process.
  • Stirring equipment with high and low speed, low and medium pressure.
  • Double-sealed rotating equipment with VOC volatilization control requirements.
