Electrical centrifugal pumps with articulated joints for oil well production

The two designs are presented for electric immersible centrifugal pumps with articulated joints for oil well production or water pumping-out from drift-directed and curved wells. The pumps units assembly of the both designs can be performed in workshop conditions or at the well mouth by technology accepted for mounting of the usual immersible centrifugal pumps. These designs allow one to pass wells bending or crooking parts without sealing break or pump seizing in an exploitation column.
