This master should be used by designers working on Port of Portland construction projects and by designers working for PDX tenants (“Tenants”). Usage notes highlight a few specific editing choices, however the entire section should be evaluated and edited to fit specific project needs.

  2. Motor shall be non-overloading under all operating conditions.

PART 2 - PRODUCTS

2.1FIRE PUMP BOOSTER SYSTEM

  1. Acceptable Manufacturers: ITT A-C, Fairbanks Morse, Peerless, Aurora, or pre-bid approved equal.
  2. Description:
  3. Provide a packaged fire pump system, designed in accordance with the requirements of NFPA pamphlet No. 20, built and listed to UL448 for fire pump units and UL778 for pump packages. The fire pump shall be UL listed and/or approved by FM Global for fire pump service at the specified rating. The pump manufacturer shall assume unit responsibility for the proper operation of the entire packaged system as specified herein.
  4. The fire pump shall be end suction type design and shall be UL listed and/or FM approved. The pump shall be designed to operate at maximum of 3,000 RPM and shall provide a rated capacity, differential pressure, and suction pressure as scheduled. At 150 percent of the rated capacity it shall develop at least 65 percent of its rated head and shall not exceed 140 percent of the rated capacity.
  5. The fire pump shall be driven by a diesel engine that is specifically listed by UL and approved by FM Global for fire pump service. Engine horsepower shall be de-rated for elevation and temperature as required by NFPA 20. The engine shall have sufficient horsepower to operate fire pump under any condition of pump load, and include water jacket heater. The engine shall be tested prior to shipment from the manufacturer’s factory and be provided with a cooling loop sized in accordance with NFPA Section82.6.
  6. Provide a UL/FM approved automatic diesel engine controller. The controller shall provide automatic starting and manual shut down and be completely assembled, wired, and factory tested by its manufacturer. The controller shall be housed in a minimum NEMA Type 2 enclosure and shall require 115 volts single phase for the battery charger. The controller shall include a recording pressure gauge with a 7-day chart to sense and record the pressure in the fire pump controller pressure-sensing line at the input to the controller.
  7. All wiring shall be installed with EMT and/or liquid tight conduit.
  8. The jockey pump shall be designed to deliver flow rate and total dynamic head as scheduled. The pump shall be of the vertical multi-stage centrifugal type, coupled to a TEFC motor. The motor shall operate at capacity as scheduled. The pump suction/discharge chamber shall be constructed of 304 stainless steel. The pump shaft shall be constructed of 316 stainless steel. The impellers, diffuser chambers, outer discharge sleeve and impeller seal ring retainers shall be constructed of 304 stainless steel. The motor stool and pump shaft coupling shall be constructed of cast iron. The impellers shall be secured directly to the pump shaft by means of a splined shaft arrangement. Shaft journal and bearings shall be tungsten carbide and aluminum oxide ceramic. Pumps shall be equipped with a mechanical seal assembly.
  9. The jockey pump controller shall be furnished with a fused disconnect, pre-piped mercold pressure switch, front mounted HAND-OFF-AUTO selector switch, and overload relays. The controller shall be housed in a minimum NEMA Type 2 enclosure. The jockey pump controller shall be UL listed.
  10. Fire pump fittings shall include an automatic air release valve, compound suction and discharge gauges (3.5-inch dials) supplied and sized in accordance with NFPA 20, a listed OS&Y isolating gate suction valve, a listed isolating butterfly discharge valve with tamper switch, and a listed wafer check valve.
  11. Engine fittings shall include dual lead acid type starting batteries and flexible exhaust connectors, with residential muffler for remote installation.
  12. A 150-gallon double-walled fuel tank and fuel tank fittings shall be provided and installed in accordance with NFPA 20. The fuel tank shall be provided with a flash arrester.

11.All of the equipment listed above shall be mounted on an open structural steel base plate.

PART 3 - EXECUTION

3.1FIRE PUMP INSTALLATION

  1. Install equipment in accordance with manufacturer’s instructions.
  2. Align the pump and motor shafts to within the manufacturer’s recommended tolerances prior to system startup.
  3. Power wiring, as required, shall be the responsibility of the Contractor. Perform all wiringin accordance with the manufacturer’s instructions and applicable local, state, and federal codes.
  4. Control wiring for remote mounted switches and sensor/transmitters shall be the responsibility of the Contractor. Perform all wiringin accordance with the manufacturer’s instructions and applicable to local, state, and federal codes.
  5. Engage the system manufacturer or certified factory-trained representative to provide startup of the fire pump system in accordance with NFPA 20, Section 11-2. Startup shall include verification of proper installation, system initiation, adjustment, and fine-tuning. Startup shall not be considered complete until the sequence of operation, including all alarms, has been sufficiently demonstrated to the Port. Startup shall occur only after all hook-ups, tie-ins, and terminations have been completed and signed off on the manufacturer’s startup request form.
  6. Engage the system manufacturer or factory-trained representative to provide on-site training for the Port. This training shall fully cover maintenance and operation of all system components.

Use if Commissioning Section 019100 is included.
