RAMSEY FIRE DEPARTMENT <br /> BODY SPECIFICATIONS <br /> <br />Class 1, Pressure Governor <br />RELIEF VALVE <br /> <br />A Waterous adjustable relief valve, specially designed for the fire service, shall be provided. The <br />valve shall be positive and quick acting and have instantaneous on/off control. When in the off <br />position, the relief valve shall functionally be removed from the system. When turned back on, it <br />shall again monitor and maintain the pressure the relief valve was set at the last time it was used. <br />Control for adjusting pressure shall be elliptical shaped for positive grip. An easily removable <br />pilot valve strainer shall be provided and be accessible from the pump operators panel. Two <br />indicator lights shall be furnished to show the position of the relief valve - amber for open and <br />green for closed. CNFPA 1901 STD 12-10.9.1) <br /> <br />Pump Packing <br />PUMP SEALS <br /> <br />(WTRS) <br /> <br />Stuffing boxes shall be integral with the pump body and be equipped with two piece glands to <br />permit adjustment or replacement of packing without disturbing the pump. Lantern rings shall be <br />located at the inner ends of stuffing boxes so that all tings of packing can be removed without <br />removal of the lantern rings. Water shall be fed into the stuffing box lantern rings for proper <br />lubrication and cooling when the pump is operating. <br /> <br />Air Pump Shift w/Manual Override <br />PUMP SHIFT CONTROL <br /> <br />(WTRS) <br /> <br />Housing shall be high tensile gray iron, three piece, horizontally split. Power transfer to pump <br />shall be through a Morse HY-VO drive chain. The chain shall be pressure lubricated through the <br />oil pump. The chain sprockets shall be cut from carburized, hardened alloy steel. Spur gears <br />shall not be acceptable. Drive shafts are to be a minimum of 2.350 diameter hardened and <br />ground alloy steel. All shafts shall be ball bearing supported. The case shall be designed to <br />eliminate the need for water-cooling. The pump shift shall be of air control type located to the <br />right of the driver. A manual override shall be provided. <br /> <br />Rotary Vane Primer <br />PRIMER PUMP <br /> <br />(WTRS) <br /> <br />Priming pump shall be a Waterous electrically driven, positive displacement, rotary type with a <br />momentary electric push button control on the pump panel. The control when activated is to <br />automatically open the priming valve and activate the primer motor at the same time, thus being <br />a one hand operation. The primer valve is to be connected to the top of both pump volutes <br />making it possible to prime the pump no matter if the pump is in pressure or volume. Primer <br />shall be automatically lubricated from a large (5 quart minimum) oil reservoir. Priming pump <br />shall be built by the manufacturer of the fire pump. <br /> <br />Page 6 of 33 <br /> <br /> <br />
