RAMSEY FIRE DEPARTMENT <br /> BODY SPECIFICATIONS <br /> <br />Discharge Manifold shall be cast as an integral part of the pump body assembly and shall provide <br />at least three full 3 1/2" openings for ultimate flexibility in providing various discharge outlets <br />for maximum efficiency, and shall be located as follows: one outlet on the right side of the pump <br />body, one outlet on the left side of the pump body, and one outlet directly on top of the pump <br />discharge manifold. <br /> <br />Impeller shall be bronze with double suction inlets, accurately balanced (mechanically and <br />hydraulically), of mixed flow design with reverse-flow, labyrinth-type, wear rings that resist <br />water bypass and loss of efficiency due to wear. The impeller shall have flame plated hub to <br />assure maximum pump life and efficiency despite the presence of abrasive particle, such as fine <br />sand, in the water being pumped. <br /> <br />Wear rings to be bronze, and shall be easily replaceable to restore original pump efficiency and <br />eliminate the need for replacing the entire pump casing due to wear. <br /> <br />Impeller shaft shall be stainless steel, accurately ground to size, and supported at each end by oil <br />or grease-lubricated anti-friction ball bearings for rigid and precise support. Bearings shall be <br />protected from water and sediment by suitable stuffing boxes, ringer rings, and oil seals. The <br />impeller shaft shall be of two-piece construction separable between the pump and pump <br />transmission to allow true separation of the transmission from the pump without disassembly of <br />either component. No sleeve type bearing shall be used. <br /> <br />Pump transmission shall be rigidly attached to the pump body assembly and be of latest design <br />incorporating a high strength, involute, tooth-form Hy-Vo chain drive and driven sprockets <br />capable of operating at high speeds to provide smooth quiet transfer of power. <br /> <br />Pump suction strainers: The suction fittings shall include removable, die .cast, zinc screens that <br />are designed to provide cathodic protection for the pump, thus reducing corrosion in the pump. <br /> <br />Warning Lights: There shall be two green warning lights in the cab. One green indicator light <br />shall be energized when the pump shift has been completed and shall be labeled "Pump <br />Engaged". If an automatic transmission is used, a second green indicator light in the cab shall be <br />energized when both the pump shift has been completed and the chassis transmission has been <br />engaged in the designated pump gear. This indicator light shall be labeled "OK to Pump". A <br />third green indicator light shall be installed on the pump operator's panel located adjacent to the <br />above throttle control and shall be energized when both the pump shift has been completed and <br />the chassis transmission has been placed in the designated pump gear. The indicator light shall <br />be labeled "Warning: Do Not Open Throttle Unless Light Is On." <br /> <br />The pump shall have a capacity of 1500 gallons per minute (U.S. gpm), NFPA-1901 rated <br />performance. The pump shall be a Waterous Fire Pump, CSU series, single stage and shall have <br />a two year warranty. <br /> <br />Page 5 of 33 <br /> <br /> <br />
