1) When securing the inlet port with bolts 1) When securing the inlet port with bolts
Refer to Table 4.2 for torque in pump abnormality and recommended
securing bolts. Secure the inlet port flange with all of the boltholes of
the size specified in the Inlet Port Flange Standard Reduced diameter
shank bolts (R.D.S.B.) listed on Table 4.2 are more reinforced bolts over
standard bolts by smoothing the portion to attach flange securing bolts to
the respective face at the equipment side. Refer to Figure 4.6 for Shape
of R.D.S.B. Secure the base with all 8 screw-holes for legs or all 8
attached legs. Follow "CAUTION" on page 4-9 about legs and bolts for
securing the base. Make sure that the recommended securing bolt may
be different depending on the method of securing the base.
