An electric submersible pump (ESP) assembly. The ESP assembly comprises a seal section that comprises a housing and at least one sacrificial anode assembly. The at least one sacrificial anode assembly comprises a sacrificial material suitable to attenuate the corrosive effect of HS fluid (hydrogen sulfide) and comprises a containment disposed inside the housing. The containment defines an annulus between an outside of the containment and an inside of the housing. The containment is disposed around the sacrificial material. The containment defines interiorly an initially void space downhole of the sacrificial material. The at least one sacrificial anode assembly defines a folded fluid flow path through the sacrificial material.

A bellows motor expansion chamber for electric submersible pumps (ESP). An ESP assembly includes an electric submersible motor between a thrust chamber and a motor expansion chamber, the motor expansion chamber including a bellows coupled to a releasable bellows anti-movement system including a heat-activated release and alterable between an immobilizing position, wherein the releasable anti-movement system prevents concertinaed movement of the bellows in the immobilizing position, and a released position, wherein the bellows is concertinaedly moveable in the released position, and wherein the releasable bellows anti-movement system is in the immobilizing position below a release temperature and in the released position above the release temperature. A filter section within a well fluid inlet of the bellows motor expansion chamber includes a least two concentric filters of varying porosity, and a housing surrounding the filters including angled ribs and flow holes.
