Modular block for electric pump with limited space requirement and associated pump

A modular block for an electric pump for a fluid product, comprising:

• a main body defining a housing extending along a main axis, the main body having a general shape having a discrete rotational symmetry relative to a reversion axis, the main axis of the housing within the housing extending on a first side of a central plane outside the central plane, the reversion axis being included in the central plane, and the main body delimiting at least one fluid reservoir, the at least one fluid reservoir being formed by at least one open volume, each of the at least one open volume having a suction opening and a discharge opening, the at least one fluid reservoir being reversible by rotation relative to the reversion axis, such that the modular block is usable in a first configuration and a second configuration wherein the modular block undergoes a rotation around the reversion axis between the first and second configurations;
• and
• a pumping device extending at least partially in said housing of said main body,
• wherein the modular block in the first configuration is adapted to be superimposed such that the modular block in the first configuration abuts with an identical modular block in the second configuration.
