COSCO protectors (seal sections) provide protection against well bore fluids entering the motor. They also serve as an oil reservoir for the motor and balance the internal pressure of the motor with the well annular pressure, a means of minimizing the possibility of well fluid entering the motor due to high pressure differentials. The thrust bearing carries the load of the pump.

Protectors combine the proven technologies of the labyrinth protector with the positive seal protector and can be supplied in Single, Tandem or Modular form depending on the type of application.

The use of multiple tandem protectors combines labyrinth and positive seal  sections, allowing the operator the flexibility to customize a protector design to a particular application.
