Abstract
A downhole pumping system includes a downhole pump that is coupled to a downhole motor. The downhole motor includes a motor protector that utilizes one or more retractable and extensible pistons, instead of an elastomeric bag, to accommodate motor oil contraction and expansion. The motor protector may also include one or more contamination containment sections for processing contaminants in downhole fluid to reduce contamination of the motor oil.
