SHI300 | best price mechanical seal shi300 burgmann

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

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
