A dialysis unit (1) having at least two piston pumps (12, 13), which act on dialysis fluid in a first conduit (3) and a second conduit (10) respectively; the at least two piston pumps (12, 13) being activated by at least one electric motor (14) via at least one universal joint (17, 18); and the unit (1) also having means (26) for varying at least one angle ( alpha , beta ) defined by the longitudinal axis of symmetry (19) of the electric motor (14) intersecting the longitudinal axis of symmetry (20) of a first piston pump (20) or, respectively, the longitudinal axis of symmetry (21) of a second piston pump (13). <IMAGE> |
