Resumen del manual


If overheating occurs, stop the pump and allow it to cool before servicing it. Refill the pump casing with cool liquid. A WARNING! I Do not remove plates, covers, gauges, pipe plugs, or fittings from an overheated pump. Vapor pressure within the pump can cause parts being disengaged to be ejected with great force. Allow the pump to cool before servicing. Strainer Check If a suction strainer has been shipped with the pump or installed by the user, check the strainer regularly, and clean it as necessary. The strainer should also be checked if pump flow rate begins to drop. If a vacuum suction gauge has been installed, monitor and record the readings regularly to detect strainer blockage. Never introduce air or steam pressure into the pump casing or piping to remove a blockage. This could result in personal injury or damage to the equipment. If backflushing is absolutely necessary, liquid pressure must be limited to 50% of the maximum permissible operating pressure shown on the pump performance curve (see Section E, Page 1). Pump Vacuum Check With the pump inoperative, install a vacuum gauge in the system, using pipe dope on the threads. Block the suction line and start the pump. At operating speed the pump should pull a vacuum of 20 inches (508 mm) or more of mercury. If it does not, check for air leaks in the seal, gasket, or discharge valve. Open the suction line, and read the vacuum gauge with the pump primed and at operation speed. Shut off the pump. The vacuum gauge reading will immediately drop proportionate to static suction lift, and should then stabilize. If the vacuum reading falls off rapidly after stabilization, an air leak exists. Before checking for the source of the leak, check the point of installation of the vacuum gauge. STOPPING Never halt the flow of liquid suddenly. If the liquid being pumped is stopped abruptly, damaging PAGE C- 2 OPERATION 10 SERIES OM-05463 shock waves can be transmitted to the pump and piping system. Close all connecting valves slowly. On engine driven pumps, reduce the throttle speed slowly and allow the engine to idle briefly before stopping. If the application involves a high discharge head, gradually close the discharge throttling valve before stopping the pump. After stopping the pump, remove the engine ignition key to ensure that the pump will remain inoperative. Cold Weather Preservation In below freezing conditions, drain the pump to prevent damage from freezing. Also, clean out any solids by flushing with a hose. Operate the pump for approximately one minute; this will remove any remaining liquid that could freeze the pump rotating parts. If the pump will be idle for more than a few hours, or if it has been pumping liquids containing a large amount of solids, drain the pump, and flush it thoroughly with clean water. To prevent large solids from clogging the drain port and preventing the pump from completely draining, insert a rod or stiff wire in the drain port, and agitate the liquid during the draining process. Clean out any remaining solids by flushing with a hose. A CAUTION OPERATION PAGE C - 3 10 SERIES OM-05463 TROUBLESHOOTING - SECTION D Review all SAFETY information in Section A. na: WARNING! I Before attempting to open or service the pump: 1. Familiarize yourself with this manual. 2. Shut down the engine and take precautions to ensure that the pump will remain inoperative. 3. Allow the pump to completely cool if overheated. 4. Check the temperature before opening any covers, plates, or plugs. 5. Close the suction and discharge valves. 6. Vent the pump slowly and cautiously. 7. Drain the pump. TROUBLE POSSIBLE CAUSE PROBABLE REMEDY PUMP FAILS TO PRIME Not enough liquid in casing. Suction check valve contaminated or damaged. Air leak in suction line. Lining of suction hose collapsed. Leaking or worn seal or pump gasket. Suction lift or discharge head too high. Strainer clogged. Add liquid to casing. See PRIMING. Clean or replace check valve. Correct leak. Replace suction hose. Check pump vacuum. Replace leaking or worn seal or gasket. Check piping installation and install bypass line if needed.
