1. The axial flow pump with variable pitch of plumbers and containing a set-up mechanism located in the plane perpendicular to the axis of a deflection disc transmitting drive to plungers with reciprocating movement in immovable block. The pump has a valve control and consists in that it has a drive sleeve (1) bearing-mounted (2,3) in the casing (4) into which a flywheel toothed ring is fixed (5) coupled with a driving unit (6) and the deflection disc (8), and in the drive sleeve (1) the set-up mechanism perpendicular to the axis is incorporated (10).<IMAGE>
