A hydraulic pump with an integrated buffer tank, comprising a path for the liquid from at least one suction inlet of the liquid into the pump to a discharge outlet of the liquid from the pump and, along said path,- downstream of said inlet, a pressure section configured to increase the pressure of the liquid,- downstream of said pressure section, a buffer tank of pressurized liquid comprising an elastically variable storage volume and an elastic opposing system of the expansion of the said storage volume, so that an increase in the pressure of the liquid in said tank corresponds to an expansion of the storage volume overcoming the opposition of said opposing system, while a decrease in the pressure of the liquid in the tank corresponds to a contraction of said storage volume,characterized in that said buffer tank comprises a plurality of distinct liquid storage chambers, each at least partly elastically expansible, all at the same discharge pressure of the liquid, said chambers being subject to said opposing system adapted to oppose their expansion
