Abstract
An apparatus (10) for the vibration control of a rising pipe (3) of a vertical pump is presented which riser pump is excited to vibrations in operation and which has a longitudinal direction. The apparatus (10) is outwardly positionable at the rising pipe and includes a vibration element (7.1, 7.2), one or more spring elements (8.1-8.4) and a guide, wherein the vibration element has an opening to surround the rising pipe (3) and is movably and elastically held by the spring element or elements (8.1-8.4), and wherein the vibration element (7.1, 7.2) is guided by guide such that the movements of the vibration element in operation are restricted to movements in a plane perpendicular to the longitudinal direction of the rising pipe.
