Abstract The present invention relates to a method and apparatus for pumping high consistency pulp, which invention is especially suitable for pumping high consistency fiber suspensions in the pulp and paper industry. One of the problems in the prior art techniques has been the difficulty of bringing high consistency pulp to the impeller of the pump or like, because high consistency pulp tends to form strong fiber network, which stops the pulp flow. A method has been developed as a solution to the problem, in which liquid is discharged from pulp during the pumping process and the liquid is fed back to the pulp to be pumped upstream of the pumping. This method is enabled by an apparatus, in which at least part of the surfaces of the pump (1) are arranged with filter surfaces (6, 7, 8, 9, 10), through which the liquid separated from pulp is returned either directly in front of the suction opening (11) of the pump (1) or to some other suitable place in the mass tower.
