Built to operate in extreme downhole environments

Defender seal extends operational life of motors used with ESPs by equalizing downhole pressure and preventing wellbore fluid migration to the motor.


Case Study: Laramie County, Wyoming

Slimline ESP system

Achieves 400% increase in pressure drawdown compared to gas lift

Defender® seals extend ESP operational life

  • Exit ports on top of the seal utilize the swirling effect of fluids to remove solids and abrasive materials, protecting shaft seals and radial bearings
  • Specially designed, high-capacity expansion chambers reduce motor oil loss due to downhole thermal cycling 
  • Premium ultra-high load thrust bearings in both unidirectional and bidirectional configurations increase run life 
  • Tungsten carbide bearings and premium mechanical seals maximize run-life performance
