Abstract

According to one or more aspects of the present disclosure, a motor protector comprises a housing defining a compensator chamber; a compensator disposed in the housing having a motor fluid end in fluid communication with a motor fluid and a well fluid end, the compensator axially moveable relative to the housing in response to the expansion and contraction of the motor fluid; and a port formed through the housing to provide fluid communication from exterior of the housing to the well fluid end of the compensator. The compensator may be one selected from the group of a bellows and a plunger.
