The invention relates to a pump comprising: a housing (1); a drum (2) having cylinders in which pistons (3) are mounted, which pistons are supported by supporting shoes (32) on a fixed inclined plate (4); and first and second fluid-distributing plates (5a, 5b) having openings (51, 52) for alternately establishing the connection between first mouths (23) of the cylinders (22) and a first inlet (11) and first outlet (12) of primary liquid, and between second mouths (24) and a second inlet (13) and outlet (14) of secondary liquid. The pump also comprises first and second strips (6a, 6b) disposed between the drum (2) and the distributing plates (5a, 5b), said strips being movable in a longitudinal direction and permitting the drum to tilt to a certain extent, forming a sealed closure between the ends of the drum (2) and the distributing plates (5a, 5b). |
