The invention relates to split-chamber pressure exchangers. Split-chamber
pressure exchangers are characterized in that the pressure exchange
chambers and the pistons thereof are split in two. Each fluid passes
through the corresponding chamber thereof, such that said fluids cannot
be mixed. The cross sections of the chambers can be varied in order to
vary the transmitted pressure. The reverse line operation can be
established and synchronized using a U-shaped tube with telescopic sides
and a fixed base filled with fluid or diametrically opposed curved lines,
and multiple arrangements can be used. Split-chamber pressure exchangers
can be used as surface or well pumping systems and the pumping fluid used
can differ from the fluid to be pumped. Different levels of any material
can be exploited at any storage site using a chamber with elastic walls
filled with fluid and attached to the bottom. Electric power can be
generated by centrifuging the pre-pumped fluid.
