Features mechanical seal sh300

  • Robust seal design – suitable for demanding light hydrocarbon applications
  • Compact cartridge seal for small seal chambers
  • Single unpressurized seal with a high pressure-non contacting containment seal
  • Stationary spring loaded unit
  • Balanced primary seal faces in materials with high thermal conductivity and strength
  • Multi-point injection of the flush fluid optional
  • Seal faces can be equipped with lubrication enhancing grooves and/or DiamondFace technology

Advantages mechanical seal sh300

  • 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
