An electrical coolant drive including a motor housing, which accommodates an electric motor and has a fluid-tight housing intermediate wall forming an electronics housing accommodating a motor electronics system, at least one through-opening is introduced into the housing intermediate wall, via which a phase connection of a stator winding of the electric motor is guided into the electronics housing in a fluid-tight and pressure-tight manner to contact the motor electronics, and a step surrounding the through-opening is introduced into the housing intermediate wall, and a first sealing ring sits in the through-opening, directly in contact with the phase connection.
