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
