    Abstract: The invention relates to an installation for pumping liquid at the bottom of a well, particularly of an oil well, comprising a linear electric motor (24) and a flap-valve pump (26) whose piston (40) is driven in a reciprocating motion by the moving element of the electric motor, this moving element and the piston (40) of the pump being guided in a cylindrical sleeve (36) axially extending inside the stator of the electric motor and of the pump body, this sleeve and the components of the motor and of the pump it contains can be raised to the surface by means of a hoisting cable attached to the upper end of the moving element of the motor (24).
