A maximum-pressure plunger plump has, coaxial with its longitudinal axis, a compression valve and a suction valve. It has a sleeve that floats on a plunger. The sleeve rests on the end facing the head of the pump on an inset. the inset is provided with a seat area for the body of the suction valve and with suction channels. The sleeve has a bushing. The suction valve is in a form of a disk. It has a spring-loaded annular body that rests on the valve-seat area that the suction channels open out of in the insert in the pump head. The plunger\s bushing (9) extends to th eend of the sleeve (7) that faces the head (2) of the pump with its face against the insert (12) and in that a sealing sleeve (15) that overlaps the area or seam of impact between the insert and the sleeve is accommodated in the flow channel between the bushing and the insert.

Maximum-pressure plunger pump with, coaxial with its longitudinal axis, a compression valve and a suction valve, with a sleeve that floats on a plunger and rests on the end facing the head of the pump on an inset provided with a seat area for the body of the suction valve and with suction channels, whereby the sleeve has a sliding bushing and the suction valve is in the form of a disk with a spring-loaded annular body that rests on the valve-seat area that the suction channels open out of in the insert in the pump head, characterized in that the plunger\s sliding bushing (9) extends to the end of the sleeve (7) that faces the head (2) of the pump with its face against the insert (12) and in that a sealing sleeve (15) that overlaps the area or seam of impact between the insert and the sleeve is accommodated in the flow channel demarcated by the bushing and the insert.
