Specifications include, but are not limited to: 1. Fire hydrants shall be rated for a working pressure of 250 Psig. (1725 kPa). 2. Fire hydrants shall be of the compression type, opening against the pressure and closing with the pressure. 3. Fire hydrants shall have a minimum 4-1/2” main valve opening and a minimum inside lower/upper barrel diameter (I.D.) of 6” to assure maximum flow performance. Pressure loss at 1,000 GPM shall not exceed the following values: 4.5” Pumper Nozzle: 4. Fire hydrants shall be three-way in design, having one pumper nozzle (size as specified) and two 2-1/2” hose nozzle(s). Nozzle thread type shall be as specified by the NFST. Nozzles shall thread counterclockwise into hydrant barrel utilizing “o” ring seals. A suitable nozzle lock shall be in place to prevent inadvertent nozzle removal. 5. The bonnet assembly shall provide an oil reservoir and lubrication system that automatically circulates lubricant to all stem threads and bearing surfaces each time the hydrant is operated. This lubrication system shall be sealed from the waterway and any external contaminants by use of “o “ ring seals. An anti-friction washer shall be in place above the thrust collar to further minimize operating torque. The oil reservoir shall be factory filled with a low viscosity; FDA approved non-toxic oil lubricant which will remain fluid through a temperature range of –600 F. to +1500 F.
