Units: Force (F) in kN (lbf); Moments (M) in kNm (lbf·ft)
1.
Forces and moments shown for TF head are for the discharge flange. For the suction flange, use the values for the next large size
head.
Loads shown are maximum allowable for standard construction. Contact Flowserve if higher values are
required or temperatures are higher than ambient
