Abstract
A pump includes at least one pump section. The pump section has a center line and comprises at least two pump steps. The pump steps have a center line and each pump step comprising a motor and one or more pump stages. The at least one pump section includes an outer casing enclosing one or more inner casings. The outer casing forms an enclosure round the pump section and has a larger diameter than the inner casings. The inner casings form an enclosure round the at least two pump steps. The center line of the pump section is displaced relative to the center line of the pump steps, thereby forming an annulus between the outer casing and the inner casing.
