Bidder <br />Triple Combination Pumper Specifications for the 45 Complies <br /> <br />City of Elk River Minnesota Yes No <br />then sends a signal to the engine ECM, which modulates fueling in order to maintain a set <br />pressure or engine speed (within engine/pump operating capabilities). There shall be no user <br />serviceable items or maintenance required on the PSG system. The PSG system shall not <br />require a mechanical drive, oil, or air supply for a means of control. <br />The pressure sensor governor system shall be operable only after the vehicle parking brake has <br />been set, the transmission is the pumping mode, and the fire pump has been engaged. <br />The pressure sensor governor system shall have two (2) modes of operation: pressure mode or <br />rpm mode. <br />When in the pressure mode, the PSG system shall automatically maintain the discharge <br />pressure set by the operator regardless of flow (within engine/pump operating capabilities). <br />In the rpm mode, the PSG system shall automatically maintain a set engine speed, regardless of <br />engine load (within engine operation capabilities). <br />A pump cavitation protection feature shall be provided which shall return the engine to idle <br />should the pump cavitate. <br />A VHS videotape describing the operation, of the pressure governor and troubleshooting <br />procedures shall also be provided with the apparatus. <br />PRIMER <br />An electric pump priming system shall be furnished with the apparatus. It shall consist of a <br />rotary vane, priming pump, driven by a 12 volt electric motor. <br />All rotating parts of the pump shall be made of corrosion resistant aluminum, stainless steel, or <br />laminated phenolic. <br />Pump cylinder shall be made of aluminum alloy, hard anodized and Teflon coated, for <br />corrosion resistance and long life. <br />The primer shall be built by the manufacturer of the fire pump. <br />A push-pull control located at the pump control panel shall operate a combination <br />manual/electric, priming valve. This valve shall utilize a switch arrangement so that as the <br />valve is manually opened, a plunger closes the switch and the primer motor is energized. A <br />minimum five (5) quart priming oil tank shall automatically lubricate and seal the sliding rotor <br />vanes, when the pump operates. <br />Priming reservoir shall be furnished with a dipstick to indicate the proper oil level. It shall be <br />accessible through an inspection door on the right (passengers) side of the apparatus. <br />Page 45 <br /> <br /> <br />
