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
