CHAPTER 1
SUCTION TUBE & SUCTION TUBE SEALING RING
Removing and Refitting
To remove the suction tube, undo the union nuts at each end of the priming suction pipe
and take off the pipe.
Remove the eight bolts and sealing washers securing the suction tube to the volute body
and take off the suction tube. This will reveal the suction tube sealing ring which has four
holes tapped ½” UNC to allow jacking bolts to be used.
Joint washers are fitted between the volute body and the sealing ring, and between the
sealing ring and the suction tube.
When refitting the suction tube sealing ring and the suction tube, ensure that the flanges
are clean. Fit new joint washers with a smear of jointing compound.
CHAPTER 2
SUCTION TUBE SEALING RING
Maintenance Attention
Check diameter ‘A’ of the suction tube sealing ring (see Fig. 1). If it exceeds 207.3mm
(8.163”) the suction tube sealing ring should be renewed.
