Motor seal protects the inflow of wellbore fluid to submersible oil-filled electrical motor and equalize the pressure between the inner part of the motor and the wellbore fluid.
It compensates oil thermal expansion working as an expansion chamber, absorbs the thrust load from the pump shaft and provides for oil cooling.
Basing on individual well conditions we offer .
- one or more bag type positive seals
- labyrinth protector designs
- protectors with thrust bearings to carry the axial thrust
