Advanced Fire Pumps

This program covers a number of advanced topics in the design and selection of fire pumps including the evaluation of water supplies to calculate suction pressure, the selection of fire pumps under a variety of water supply situations, and the evaluation of discharge pressure to make sure that system pressure does not get too high, especially in high-rise buildings.  Balancing the pressure in the system to meet all of the requirements of NFPA 14 and NFPA 20 both with and without pressure reducing devices and situations with multiple water supplies (with different pressures) will be discussed.  The use of break tanks as permitted by NFPA 22 will also be discussed.

Due to the advanced nature of the program, it is recommended that only those already knowledgeable in basic hydraulic calculations (including use of the Hazen-Williams formula and adjustments for elevation) attend.  Anyone needing a refresher on these topics is encouraged to read Chapters 30 and 31 in the NFSA text, Layout, Detail and Calculation of Fire Sprinkler Systems, 2nd edition.  This program will be an excellent study session for those people seeking NICET Level III and Level IV certification.

 

Learning Outcomes: By the end of the program, the participant will be able to: 

  1. Calculate the suction pressure at the suction flange of a pump.
  2. Recognize the unique requirements for suction pipe arrangements in super high-rise buildings as required by the International Building Code.
  3. Calculate the size of the test header pipe as required by NFPA 20.
  4. Select an appropriate size fire pump for a variety of situations including the situation where multiple pumps will be installed in both parallel and series and situations where more than one water supply (with different pressures) are present.
  5. Calculate the discharge pressure and recognize where pressure reducing valves will be required and select a pressure reducing valve to meet the requirements of NFPA 14 and NFPA 20.
  6. Recognize the rules for using a break tank in accordance with NFPA 22.
  7. List the special requirements of NFPA 20 for super high-rise buildings.
