    • 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.

    • A spherical magnet is formed as a hollow sphere having a fluid tight outer surface of a first magnetic pole and an inner surface having a second magnetic pole that is magnetically opposite the first pole. A plurality of individual thin flexible rectangular plate magnets are arranged as a continuous outer layer of the spherical magnet. Each individual plate magnet has four sides, an inner magnetic portion and an outer non-magnetic portion that extends around all four sides of the magnetic portion. Each inner magnetic portion includes a first face disposed on the outer surface and having the first pole and a second face opposite the first face, disposed on the inner surface and having the second pole.
    • 形成具有第一磁极的流体密封外表面的空心球体和具有与第一极磁性相对的第二磁极的内表面的球形磁体。 多个单独的薄柔性矩形板磁体被布置为球形磁体的连续外层。 每个单独的板状磁体具有四个侧面,内部磁性部分和外部非磁性部分,其围绕磁性部分的所有四个侧面延伸。 每个内磁性部分包括设置在外表面上并且具有第一极和与第一面相对的第二面的第一面,设置在内表面上并具有第二极。
