✦ Synopsis


A pressure balance and temperature compensation chamber for the shaft seal on a submersible electric motor is described. A chamber between two shaft seals has a flexible element for temperature compensation. A non-return valve allows fluid to be expelled from the chamber but not enter. A compensating element compensates pressure across the second shaft seal. Redundant seal components are also included.
