<br />PUBLIC WORKS SERVICES DEPARTMENT 15 <br />Flygt Sewage and Storm Pump Preventative Maintenance Project <br />pump/mixers and the fifteen storm pumps are as follows: <br /> <br />SERVICE – 21 POINT CHECK LIST <br />□ Check electrical condition of insulation on power cable and on all phases of motor. (In Meg <br />Ohms) <br />□ Check for any loose or faulty electrical connections within the pump control panel. <br />□ Measure resistance between stator windings (In Ohms) <br />□ Check voltage supply between all phases of the electrical control panel. (VAC) <br />□ Check voltage balance between all phases on the load side* of the pump control with pump <br />on. (VAC) <br />□ Check amperage draws on all phases of the pump motor. (In Amps) <br />□ Check condition and operation of motor thermal protectors control system (if so equipped). <br />□ Removal of Flygt pump(s) from lift station for physical inspection. <br />□ Check condition of upper shaft seals (inspect condition of motor housing). <br />□ Check condition and operation of leakage detector (if so equipped). <br />□ Check lower shaft seals (inspect condition of oil). <br />□ Change oil if needed (cost of oil included). <br />□ Check for worn or loose impeller. <br />□ Check all impeller wear rings. (Note: Wear rings are not covered by warranty and must be <br />purchased by customer if in need of replacement) <br />□ Check for noise in upper and lower bearings. <br />□ Check physically for damage of pump and power cable. <br />□ Clean, reset, and check operation of level sensors. <br />□ Check for correct shaft rotation. <br />□ Reinstall Flygt pump and check for leakage at the discharge connection. <br />□ Test of pump operation cycle (if level of liquid in station permits). <br />□ Check operating of valves and pipes in station. <br /> <br />2. Repairs such as replacement and installation of O-rings and other minor parts that are <br />determined to need replacing during such inspection. The cost of all such “minor <br />parts” shall be included in the contract price and shall not be an extra charge. All parts <br />considered “minor parts” and the prices used to calculate the contract prices are set <br />forth in Attachment F. These repairs do not include overhaul or shop repairs. <br />6.1.A. - Page 32
