FIELD: machine building.
SUBSTANCE: invention relates to machine building, in particular to shaftless pump units, and is intended for recuperation of hydraulic power and removal of gas-air mixture. Shaftless pump unit for removing the gas phase by installing a hydraulic turbine, the working fluid of which is oil, supplied to the transport tanks of the oil tanker, driven by said turbine of the shaftless pump, provides for forced removal of gas-air mixture from gas space of tanker and its transportation to vapour recovery unit.
EFFECT: reduction of losses from evaporation of light fractions of hydrocarbons and reduction of power consumption.
