SHI300

Features

  • Robust seal design - suitable for demanding light hydrocarbon applications
  • Compact cartridge seal - can be fitted in older pumps with small seal chambers
  • Unpressurized inboard seal with a high pressure-non contacting containment seal on the outboard – fully-rated to pipeline pressure
  • Stationary spring loaded unit
  • Balanced primary seal faces - in materials with high thermal conductivity and strength
  • Multi-point injection - uniform heat distribution
  • DiamondFace® technology optional

Advantages

Operational Excellence
  • High Performance seal for single and multi fluid type pipeline services with variable pressures and speeds
  • Low amount of heat generation, hence minimal temperature rise in the seal faces
  • Suitable for flashing and non-flashing light hydrocarbons, even with low vapor pressure margins
  • Seal faces have soft torque transmission
  • Seal faces are shrouded in steel collars so that they cannot break apart in pieces in an emergency case
  • Resistant to alignment issues between the pump case and shaft because of stationary springs
  • Containment seal is rated for full dynamic pressure of primary seal, i.e. high degree of safety and environmental protection
  • Seal face materials are resistant to solids in the pumped fluid

Technical Excellence
  • Simple installation due to pre-assembled cartridge
  • Seal faces are designed with FEA & CFD and qualified & tested in the lab
  • Can be fitted in older pumps with small seal chambers or stuffing boxes
  • High degree of standardization ensures fast deliveries and smart part inventories

Sustainability Excellence
  • Zero emission seal design for sustainable environmental protection in combination with plan 75 or plan 76
  • Minimized friction and energy consumption
