to Fig. 5-4).
When you fix the pump, use of the bolts regulated grade, size, number and tightening torque
(Refer to Table 5-2 and Table 5-3). And use all the bolt-holes of the inlet flange of the pump. Refer
to Fig. 5-5 about usage of the bolt.
The sets of half-thread bolt and nut should be used to fix the inlet flange of the pump. Make
