These robust seals are designed for use on difficult applications, including oil pipeline pumping, water injection and boiler feed duties.

• High speeds – Stationary multi-spring designfor even face loading
• High pressures – Robust seal-faces minimize the effects of pressure distortion 
• Monolithic seal-faces – maintain flatness under temperature fluctuations
• Axial displacement capacity to accommodate machine build tolerance and differential thermal expansions
• Seal face design optimized using FEA and hydrodynamic algorithms
• Seal-face loading factory set and statically tested prior to despatch
• Sculpted lug drive for improved torque transmission
• Compact and robust design allows seal to be fitted on close bearing centre pumps
