fire protection pumps
Fire Protection Pumps
  • End Suction Pumps
  • Vertical In-line
  • Horizontal Split Case
  • Vertical Mounted Split Case
  • Vertical Turbine
compliance to nfpa 20
Compliance to NFPA 20
  • 100% Flow at 100% Head
  • Maximum of 140% of Head at Shutoff
  • Minimum of 65% of Head at 150% of Flow
maximum allowed pressure
Maximum Allowed Pressure
  • The pump shutoff pressure plus the maximum static suction pressure shall not exceed the pressure for which the system components are rated for.
  • Pressure relief valves shall not be used as a means to meet this requirement.
  • Variable speed pressure limiting control drivers are acceptable in meeting this requirement (new in NFPA 2003).
fire pump drivers
Fire Pump Drivers
  • Electric Motors
  • Diesel Engines
  • Steam Turbines
  • Combination of the above
fire pump accessories
Fire Pump Accessories
  • Suction pressure/vacuum gauge.
  • Discharge pressure gauge.
  • Automatic air release valve
  • Casing relief valve (electric driven)
  • Main pressure relief valve (diesel driven and VFD applications)
suction pipe fittings
Suction Pipe & Fittings
  • Suction can be either from a city water supply or a fire water storage tank.
  • Suction shall be sized so that at 150% of rated capacity the velocity in the suction pipe located 10 pipe diameters upstream of the pump suction flange shall not exceed 15 ft/sec.
  • Concentric reducers are not allowed in the suction piping.
  • UL/FM OS&Y gate valve only.
relief valves
Relief Valves
  • Used on Diesel Engines
  • Used with Variable speed pressure limiting control devices
  • Spring direct acting or pilot operated.
  • Relief discharges to an open or closed waste cone.
  • Discharges to suction source or splash block
test meters
Test Meters
  • Where water usage or discharge is not permitted for the duration of the test.
  • Installed with upstream and downstream pipe runs per meter manufacturer.
  • Where meter downstream run goes back to suction side of pump proper pipe runs must be followed per NFPA-20.
  • A throttling valve shall be installed downstream of the flow meter.
hose valve test header
Hose Valve Test Header
  • Hose test valves are rated for 250 GPM.
  • Hose valves shall be mounted on a test head.
  • A UL/FM isolation valve shall be installed upstream of the test head.
  • A Ball drip valve shall be installed if the test head is mounted outside the building to prevent freezing.
specialty valves accessories
Specialty Valves & Accessories
  • Backflow Preventers
  • Suction Control Valves
  • Pressure Regulating Valves
  • Alarm Check Valves
  • Siemese Valves
  • Tamper Switches
  • Flow Switches
electric drive pumps
Electric Drive Pumps
  • Power derived by a reliable power source or two or more approved independent sources.
  • Second power source shall be from a second utility or on-site power generation
  • Automatic Transfer switch to be used if two or more power sources are used.
electric drive starting methods
Electric Drive Starting Methods
  • Across The Line
  • Part Winding
  • Wye Delta (open)
  • Wye Delta (closed)
  • Primary Resistance
  • Auto Transformer
  • Solid State
diesel engine driven accessories
Diesel Engine Driven Accessories
  • Cooling System

  • Raw Water outlet Drain
  • Battery Racks
  • Exhaust System
  • Air Intake Louver for Engine Air Intake (used with buildings)
pressure maintenance pumps
Pressure Maintenance Pumps
  • Rated for not less than normal leak load. (normally 1% of rated fire flow and 10 psig above rated boost pressure.
  • Discharge pressure shall be sufficient to maintain desired system pressure.
  • Where the shutoff pressure is greater than the pressure ratings of the system components a relief valve shall be installed on the pump discharge.
house utilities per nfpa 20
House Utilities (per NFPA-20)
  • Approved or listed source of heat
  • Artificial Lighting
  • Emergency lighting (including fixed and portable).
  • Ventilation
  • Drainage
