A high-pressure piston pump has a cylindrical housing where is installed a piston with formation of a front and a back working chambers, suction, back and pump-in valves, and eccentric-con-rod mechanism of the piston drive. Additional cylindrical housing with a piston is placed symmetrically to the first one at the opposite side of the driving shaft to which are placed two eccentrics, and on those there are installed roller bearings connected to the rods hinged to the pistons of both cylinders; at that the pressure cavity of the additional, and the back working chamber of the first cylinder are connected by a hydro-line.
