0 SERIES OM-01087 INTRODUCTION Thank You for purchasing a Gorman‐Rupp pump. Read this manual carefully to learn how to safely install and operate your pump. Failure to do so could result in personal injury or damage to the pump. This pump is an 0 Series, closed impeller, self‐prim ing centrifugal model, with straight‐in suction, with out a suction check valve. It is designed to handle petroleum products or other clean liquids that do not contain large entrained solids.
0 SERIES OM-01087 SAFETY ‐ SECTION A This information applies to 0 Series ba sic pumps. Gorman‐Rupp has no con trol over or particular knowledge of the power source which will be used. Refer to the manual accompanying the power source before attempting to begin oper ation. This manual will alert personnel to known procedures which require spe cial attention, to those which could damage equipment, and to those which could be dangerous to personnel.
OM-01087 tional Electric Code and all local codes. If there is a conflict between the instruc tions in the manual accompanying the unit and the National Electric Code or the applicable local code, the National or local code shall take precedence. If this pump is used with volatile and/or flammable liquids, overheating may produce dangerous fumes. Take pre cautions to ensure the area surrounding the pump is adequately ventilated.
0 SERIES OM-01087 INSTALLATION - SECTION B Review all SAFETY information in Section A. Since pump installations are seldom identical, this section offers only general recommendations and practices required to inspect, position, and ar range the pump and piping. Most of the information pertains to a standard static lift application where the pump is positioned above the free level of liquid to be pumped. configuration, and priming must be tailored to the specific application.
OM-01087 AND REPAIR section of this manual and per form duties as instructed. e. If the pump and engine have been stored for more than 12 months, some of the compo nents or lubricants may have exceeded their maximum shelf life. These must be inspected or replaced to ensure maximum pump serv ice. If the maximum shelf life has been exceeded, or if anything appears to be abnormal, contact your Gorman‐Rupp distributor or the factory to deter mine the repair or updating policy.
0 SERIES SUCTION LINES To avoid air pockets which could affect pump prim ing, the suction line must be as short and direct as possible. When operation involves a suction lift, the line must always slope upward to the pump from the source of the liquid being pumped; if the line slopes down to the pump at any point along the suction run, air pockets will be created. Fittings Suction lines should be the same size as the pump inlet.
OM-01087 0 SERIES Figure 2. Recommended Minimum Suction Line Submergence vs. Velocity DISCHARGE LINES head, gradually close the discharge throttling valve before stopping the pump. Siphoning Do not terminate the discharge line at a level lower than that of the liquid being pumped unless a si phon breaker is used in the line. Otherwise, a si phoning action causing damage to the pump could result.
0 SERIES OM-01087 When checking alignment, disconnect the power source to ensure that the pump will remain inoperative. Figure 3B. Aligning Non‐Spider Type Couplings Adjusting the alignment in one direction may alter the alignment in another direc tion. check each procedure after altering alignment. Coupled Drives When using couplings, the axis of the power source must be aligned to the axis of the pump shaft in both the horizontal and vertical planes.
OM-01087 Tighten the belts in accordance with the belt manu facturer's instructions. If the belts are too loose, they will slip; if the belts are too tight, there will be excessive power loss and possible bearing failure. Select pulleys that will match the proper speed ra tio; over speeding the pump may damage both pump and power source. 0 SERIES Ideal drive belt tension is the lowest tension at which the belt will not slip under peak load condi tions. Do not over‐tension drive belts.
OM-01087 0 SERIES OPERATION - SECTION C Review all SAFETY information in Section A. Follow the instructions on all tags, labels and decals attached to the pump. coming liquid to evacuate the air. After the pump and piping system have completely filled, evacu ate any remaining air pockets in the pump or suc tion line by loosening pipe plug or opening bleeder valves. Once the pump casing has been filled, the pump will prime and reprime as necessary.
OM-01087 ature supplied with the motor for specific instruc tions. OPERATION 0 SERIES Overheating can occur if operated with the valves in the suction or discharge lines closed. Operating against closed valves could bring the liquid to a boil, build pressure, and cause the pump to rup ture or explode. If overheating occurs, stop the pump and allow it to cool before servicing it. Refill the pump casing with cool liquid.
OM-01087 0 SERIES 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 shock waves can be transmitted to the pump and piping system. Close all connecting valves slowly. After stopping the pump, lock out or disconnect the power source to ensure that the pump will re main inoperative. Checking bearing temperatures by hand is inaccu rate.
OM-01087 0 SERIES TROUBLESHOOTING - SECTION D Review all SAFETY information in Section A. Before attempting to open or service the pump: 1. Familiarize yourself with this manual. 2. Disconnect or lock out the power source to ensure that the pump will remain inoperative. 3. Allow the pump to completely cool if overheated. 4. Check the temperature before open ing any covers, plates, or plugs. 5. Close the suction and discharge valves. 6. Vent the pump slowly and cautiously. 7. Drain the pump.
