FIGURE A.3.2.2（B）Anchor Bolt and Sizing Block
3.2.3 Concreting
Loosen the adjusting bolt and remove the sizing block before concreting into the base. The
base is mounted on a steel plate. After re-checking alignment, concrete the anchor bolts. Be
sure to tighten the anchor bolts after the concrete has solidified. After fastening the bolt, it is
necessary to check the height and flange alignment size. Any error should be compensated
by re-alignment. After aligning, start pouring the base. Note that there are no bubbles
forming under the base, in particular that there must be no gaps between the foundation
and the base to ensure that the base is completely fixed.
3.3 Suction Pipeline of Fire Pump
1. Installation and fitting requirements for fire pump pipelines must be in accordance with
NFPA 20 section 4.
2. See SCF、ESF、VTP pump manual for more detailed usage requirements.
3.3.1 Pump Suction Pipeline for ESF and SCF
Suction pipeline installation shall meet the following requirements:
1. The inlet and outlet pipeline size at least meet the supply of the fire pump operating at
150% rated flow;
2. The pipeline shall be independently and firmly supported to reduce the vibration and to
prevent the weight of the pipeline from being pressed on the pump;
3. The pipe connecting the fire pump and the equipment is short, when the two are not the
same foundation, the connection pipe should be equipped with metal flexible joints (do
not use rubber flexible joints), as far as possible to reduce the impact on the pump of
