A containment structure for an actuation unit for immersion pumps, particularly for compact immersion pumps for wells, comprising a box-like casing, which is fitted over an electric actuation motor for pumps, which it encloses hermetically, a cartridge, which accommodates a driving device of the motor and has a radial space occupation that is substantially smaller than, or equal to, the radial space occupation of the casing, quick-coupling connectors provided at a head of the cartridge and at a bottom of the casing, adapted for the quick and reversible connection of the cartridge to the casing. The connectors comprise at least one power supply connector, adapted to electrically connect the driving device to an electric power supply, with which the casing is equipped, at least one control connector, which is adapted for the functional connection of the driving device to the motor for driving it.
