1. A pump for delivering a fluid, the PUMP comprising: an electromagnetic drive; an inlet; an outlet; and a delivery chamber, wherein a suction valve is arranged between the inlet and the delivery chamber, wherein the suction valve has a valve body with a valve seat pointing in a direction toward the outlet, and a valve member interacting with the valve seat, wherein the valve member is loaded under prestressing against the valve seat into a closed position of the suction valve and allows fluid to pass through in a pumping direction by the valve member lifting off the valve seat against the prestressing, wherein the valve body is accommodated in a receptacle in a pump part, wherein the valve body is assigned a flexible damping arrangement which loads the valve body into a starting position, wherein the flexible damping arrangement comprises a damping plate being supported against a calking ring, wherein a piston rod of the electromagnetic drive is axially displaceable in the direction of the valve body, wherein the flexible damping arrangement allows an axial displacement of the valve body, wherein the flexible damping arrangement further comprises an elastomeric ring surrounding the valve body and abutting against a flange of the valve body, and wherein the flexible damping arrangement is arranged in a receptacle of a guide sleeve guiding the piston rod, and wherein the elastomeric ring is supported against an abutment which is mounted in an axially immovable manner with respect to the receptacle.
