2. Reference
 NFPA 20 (Standard for Installation of Centrifugal Fire Pumps)
 Fire Pump Hand Book
 www.pump-zone.com

3. Overview
 Design Purposed : Protect Life and Property
 Include a UL/FM (Underwriters Laboratory / Factory Mutual)
listed Pump, Driver and Controller
 Comply with NFPA 20 (National Fire Protection Association)
 Listed Pump are not Designed or Manufactured to API 610
 For Users, Fire Pump Systems are (or should be) a Once a
Week Test Requirement for 30 minutes
 The “Controller” is the brain of the system

4. Basic Philosophy
 The controller monitors the conditions in the fire protection
system and turns the pump on under specified conditions
 A pressure switch inside the controller is generally connected
through a small diameter, corrosion-resistant metallic or copper
pipe or tube to the fire protection system
 When a drop in pressure occurs such as caused by a sprinkler
or a hose valve being opened, the pressure switch senses the
loss of pressure and turns the driver on
 Smoke detectors, heat detectors, and other sensing devices can
also be connected to the controller to start the pump

5. Typical Sensing Line Arrangement

6. Pump Characteristic
 Pumps shall furnish not less than 150 percent of rated capacity
at a total head of not less than 65 percent of the total rated head
 The shutoff head shall not exceed 140 percent of rated head for
any type pump

7. Pump Characteristic
 At 150 percent of rated capacity, head will range from a minimum of 65
percent to a maximum of just below rated head
 Shutoff head will range from a minimum of 101 percent to a maximum
of 140 percent of rated head

8. Rated Pump Capacity
 Fire pumps shall have the following rated capacities in gpm
(L/min) and shall be rated at net pressures of 40 psi (2.7 bars) or
more

9. Materials
 Materials of construction vary with the type of the system and
the fire fighting fluid
 The most common in land-based application : Cast Iron case
with Bronze impellers and wear surfaces (suitable for fresh
water, brackish or even salt water)
 For aggressive/corrosive fluids : Bronze including Zinc-Free and
Nickel-Aluminum Bronze

26. Jockey Pumps
 The jockey pump or pressure maintenance pump is
intended to maintain the system pressure only
 It is generally sized about 1% of the flow of the main
fire pump
 The jockey pump prevents the main fire pump from
starting when small leaks for packing drips occur
throughout a system
 The set pressure is generally 15 to 20 PSI above
that of the main fire pump

27. Jockey Pumps
 Regenerative Turbine Pumps
 Vertical Multi-stage

28. Piping Connection for Fire Pump & Jockey Pump
Piping connection for pressure-sensing line

33. Packaged Fire Pump with Electric Pump Set

34. Packaged Fire Pump with Diesel Engine

35. Why Packaged Fire Pump Systems?
 Single source responsibility
 Manufacturer takes full responsibility for all aspects of
design and engineering
 Less time required on the job site

36. Testing Organizations
 F.M. and U.L. are testing organizations
 All U.L. listed pumps have this label affixed to the
pump
 All F.M. approved pumps have this label affixed to the
pump

37. Underwriters Laboratories (UL)
 UL lists and approves equipment for fire pump service
 UL witnesses testing of fire pumps for specific flow rates
 UL448 sets the standards for certification of centrifugal
pumps
 UL1247 for Diesel Engines
 UL 218 for Controllers (Engine and Motor Controller)

38. UL448 (Pump Certification)
 Test the Pump Performance : Total Differential Head
(TDH), Capacity, Efficiency or Power Requirement
 Review the Material of Construction (for strength and
corrosion resistance
 Hydrotest Certification
 Hydrostatic Integrity and Hydraulic Performance of
each unit bearing

39. UL1247 (Diesel Engine Certification)
 Dynamometers test including performance checks of
the speed control and overspeed shutdown system
 Tested for the ability to start under a wide range of
condition both hot and cold

40. UL218 (Controller Certification)
 Review for safety
 Inspected with special attention to the ability of starting signal under
emergency condition
 For Diesel Engine Controller includes:
- Providing a starting signal to the engine
- Providing charging current for the batteries
- Perform a weekly starting and run test of the engine
- Failure of engine to start
- Shutdown from overspeed
- Battery Failure, Battery Charge Failure
- Pressure recorders to sense pressure in the fire protection system

41. UL218 (Controller Certification)
 For Electrical Motor Controller :
- Focus on the ability to start the motor drive
- The controllers are different standard motor
controller (best demonstrated of the circuit breaker
for protection against overcurrents and short circuits)
- Another difference is that once a fire pump controller is under
emergency conditions, it is prevented from shutdown
 UL lists no Controller for installation in hazardous area.
 For Division I or II classification they must either have a purge
system (X or Z purge system) or be explosion proof

42. Factory Mutual (FM)
 Factory Mutual is an insurer in addition to being an
approval agency
 Factory Mutual approves and tests all types of fire
pump and fire system equipment
 Factory Mutual also approves installation & design of
fire pump and fire protection systems. This a
requirement on an FM insured project
