  • Convenient to assemble, disassemble, and install.
  • Seal uses spiral groove technology to create a gas film principle between the seal faces. During operation, the inert gas penetrates throught the spiral grooves to generate a lift, and establish a sealing gap. 
  • Non-contacting Seal Faces. Required power consumption is just 10%~15% in compararison to wet seal. Minimized wearable materials, support equipments and maintence costs. 
  • Below normal pressure, utilized rotation speed in influenzing atomospheric pressure as  inert gas to establish sealing gap.   
  • Non-complicated assesory system, convinient to restore, highly dependable.
  • In normal operation, dry gas seal may continously run for years without the need to stop for maintenace.
  • Designed for various rotating equipment, such as pumps, steam turbines, mixers, agitators, blowers, windmills, & other rotating equipment.
