Abstract
The present disclosure relates, according to some embodiments, to fluid pump apparatuses. A fluid pump apparatus may comprise a suction compensator, a housing compensator, and a pump. A suction compensator may comprise an ambient fluid compensator, an ambient fluid bladder, and a spring compensator, wherein the spring compensator comprises a first separator partitioning an internal volume of the spring compensator into a first suction fluid chamber and a compensation fluid chamber. A housing compensator may comprise a second separator partitioning an internal volume of the housing compensator into a second suction fluid chamber and a lubrication fluid chamber. The compensation fluid chamber may be in fluid communication with the suction compensator. The first suction fluid chamber may be in fluid communication with the second suction fluid chamber. A pump may comprise a housing defining a lubrication fluid compartment in fluid communication with the lubrication fluid chamber.
