FIELD: engines and pumps.
SUBSTANCE: pump contains a central bodies, united among themselves and within the elastic bodies, which, in turn, are within hydraulic chambers. Electromagnets are located along the axis of the pump. Anchor electromagnets are associated with piston mounted on hydraulic fluid filled chambers. Electromagnets are mounted with their axes along the axis of the central body.
EFFECT: increasing the power of electromagnets in the pump in small diameter wells.
