Apparatus and pumping systems including the apparatus are described, the apparatus including a protector body comprising a material allowing expansion and contraction of an internal fluid, the body serving as a barrier between fluids external of the body and the internal fluid. The body has first and second ends, at least one end adapted to connect the body to other components, the protector body further comprising structural features permitting facile cleanout and reuse of the protector body. Methods of use of the apparatus and systems are described, particularly in oilfield exploration, testing, and production. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It will not be used to interpret or limit the scope or meaning of the claims.
