SHI366 Burgmann mechanical seals

SHI366

Features

  • Robust seal design – especially for demanding crude oil applications
  • Compact cartridge seal for small seal chambers
  • Single unpressurized seal with containment high-pressure throttle design
  • Stationary spring loaded unit
  • Balanced seal faces in materials with high thermal conductivity and strength
  • Inserted seal face
  • Multi-point injection of the flush fluid optional
  • Seal faces can be equipped with lubrication enhancing hydropads and/or also DiamondFace technology

Advantages

Operational Excellence

  • High performance seal design for alternating media properties and operating conditions with high pressures and also sliding velocities
  • Low amount of heat generation, hence minimal temperature rise in the seal faces
  • Seal faces have soft torque transmission
  • Seal faces are shrouded in steel colars so that hey cannot break apart in pieces in an emergency case
  • Resistant to alignment issues between the pump case and also shaft because of stationary springs
  • Atmosphere side high pressure double throttle design suitable for full product pressure
  • Seal face materials are resitant to solids in the pumped fluid
  • Optimized for operation also with sand or particles

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 also smart part inventories

Sustainability Excellence

  • Zero emission seal design for sustainable environmental protection
  • Minimized friction and also energy consumption
