FIELD: engines and pumps.
SUBSTANCE: invention relates to submerged centrifugal pumps intended for pumping over aggressive media, including those containing abrasive particles and can be used for hydrocarbon production at oil fields. The submerged centrifugal pump stage consists of a disk and a guide device incorporating a hub, a vane and outer rim. The disk and guide device flow-through section is made up of several segments made from wear-resistant material. The segments are attached to the hub by outer rings arranged with interference fit.
EFFECT: pump longer life.
