A centrifugal pump with body and cover connected with fixation parts in horizontal split plane coinciding with the axis of the rotor placed in respective recesses in the body and the cover resting on slide bearings, with working wheel fixed on shaft, with two-side inlet, with cylindrical throttling groove seals at each side of the inlet. At each side of the inlet of the working wheel with implementation of rotor and stator parts of friction pair end throttling groove seal is installed, this forms with the cylindrical throttling groove seal hydraulic balancing device of rotary type with direction of liquid flow in end slot from periphery to center. Slide bearings are build-in to recesses placed in the joint between the body and the cover with lubrication by liquid being pumped, this is supplied from pressure cavity to inlet to bearing gap with outlet to respective suction cavities of working wheel.
