we can offer different types and series seal section to adapt individual well conditions.

Critical Function

1.Prevents well fluids from entering the motor.

2.Provides a reservoir for motor oil expansion and contraction caused by temperature and pressure changes.

3.Equalizes the internal pressure of the motor with the pressure in the well annulus.

4.Absorbs the pump shaft thrust on the seal thrust bearing.

5.The temperature type have 150℃ and l80℃.
