Note:  On water lubricated pumps, the length of column sections (B1) is limited to 1.22 metres, to allow for inclusion of a Centre Bearing Holder (A5) between each flange.  Bearings are required at each column flange, except the lowest, which is adjacent to the bottom assembly.  If the topmost column section is shorter than 1.22 metres, a bearing will not be required under the Discharge Head.
