10 SERIES OM−05463 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 Installation, Operation, and Maintenance manual is designed to help you achieve the best performance and longest life from your Gorman-Rupp pump. This pump is a 10 Series, semi-open impeller, selfpriming centrifugal model with a suction check valve.
10 SERIES OM−05463 SAFETY − SECTION A This information applies to 10 Series engine driven pumps. Refer to the manual accompanying the engine before attempting to begin operation. Because pump installations are seldom identical, this manual cannot possibly provide detailed instructions and precautions for each specific application.
OM−05463 Do not operate an internal combustion engine in an explosive atmosphere. When operating internal combustion engines in an enclosed area, make certain that exhaust fumes are piped to the outside. These fumes contain carbon monoxide, a deadly gas that is colorless, tasteless, and odorless. 10 SERIES Never tamper with the governor to gain more power. The governor establishes safe operating limits that should not be exceeded. The maximum continuous operating speed for this pump is 3600 RPM.
10 SERIES OM−05463 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 arrange the pump and piping. specific application.
OM−05463 10 SERIES c. Carefully read all tags, decals, and markings on the pump assembly, and perform all duties indicated. d. Check levels and lubricate as necessary. Refer to LUBRICATION in the MAINTENANCE AND REPAIR section of this manual and perform duties as instructed. The pump assembly can be seriously damaged if the cables or chains used to lift and move the unit are improperly wrapped around the pump. Mounting e.
SERIES forced type to prevent collapse under suction. Using piping couplings in suction lines is not recommended. Line Configuration Keep suction and discharge lines as straight as possible to minimize friction losses. Make minimum use of elbows and fittings, which substantially increase friction loss. If elbows are necessary, use the long-radius type to minimize friction loss. Connections to Pump Before tightening a connecting flange, align it exactly with the pump port.
OM−05463 10 SERIES If it is necessary to position inflow close to the suction inlet, install a baffle between the inflow and the suction inlet at a distance 1-1/2 times the diameter of the suction pipe. The baffle will allow entrained air to escape from the liquid before it is drawn into the suction inlet. Suction Line Positioning The depth of submergence of the suction line is critical to efficient pump operation. Figure 2 shows recommended minimum submergence vs. velocity.
10 SERIES With high discharge heads, it is recommended that a throttling valve and a system check valve be installed in the discharge line to protect the pump from excessive shock pressure and reverse rotation when it is stopped. If the application involves a high discharge head, gradually close the discharge throttling valve before stopping the pump.
OM−05463 10 SERIES OPERATION − SECTION C Review all SAFETY information in Section A. Follow the instructions on all tags, labels and decals attached to the pump. Add liquid to the pump casing when: This pump is designed to handle dirty water containing specified entrained solids. Do not attempt to pump volatile, corrosive, or flammable liquids which may damage the pump or endanger personnel as a result of pump failure. Once the pump casing has been filled, the pump will prime and reprime as necessary.
OM−05463 line. Air from the suction line will be discharged through the bypass line back to the wet well during the priming cycle. When the pump is fully primed and liquid is flowing steadily from the bypass line, open the discharge throttling valve. Liquid will then continue to circulate through the bypass line while the pump is in operation. Lines Without a Bypass Open all valves in the discharge line and start the engine.
OM−05463 10 SERIES shock waves can be transmitted to the pump and piping system. Close all connecting valves slowly. Cold Weather Preservation On engine driven pumps, reduce the throttle speed slowly and allow the engine to idle briefly before stopping. In below freezing conditions, drain the pump to prevent damage from freezing. Also, clean out any solids by flushing with a hose.
10 SERIES OM−05463 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. 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.
OM−05463 TROUBLE PUMP STOPS OR FAILS TO DELIVER RATED FLOW OR PRESSURE PUMP REQUIRES TOO MUCH POWER PUMP CLOGS FREQUENTLY EXCESSIVE NOISE PAGE D − 2 10 SERIES POSSIBLE CAUSE PROBABLE REMEDY Air leak in suction line. Correct leak. Lining of suction hose collapsed. Replace suction hose. Leaking or worn seal or pump gasket. Check pump vacuum. Replace leaking or worn seal or gasket. Suction intake not submerged at proper level or sump too small.
10 SERIES OM−05463 PREVENTIVE MAINTENANCE Since pump applications are seldom identical, and pump wear is directly affected by such things as the abrasive qualities, pressure and temperature of the liquid being pumped, this section is intended only to provide general recommendations and practices for preventive maintenance. Regardless of the application however, following a routine preventive maintenance schedule will help assure trouble-free performance and long life from your Gorman-Rupp pump.
10 SERIES OM−05463 PUMP MAINTENANCE AND REPAIR - SECTION E MAINTENANCE AND REPAIR OF THE WEARING PARTS OF THE PUMP WILL MAINTAIN PEAK OPERATING PERFORMANCE. STANDARD PERFORMANCE FOR PUMP MODELS 13D1−19 Based on 70_ F (21_ C) clear water at sea level with minimum suction lift. Since pump installations are seldom identical, your performance may be different due to such factors as viscosity, specific gravity, elevation, temperature, and impeller trim.

OM−05463 PUMP AND SEAL DISASSEMBLY AND REASSEMBLY Review all SAFETY information in Section A. Follow the instructions on all tags, label and decals attached to the pump. This pump requires little service due to its rugged, minimum-maintenance design. However, if it becomes necessary to inspect or replace the wearing parts, follow these instructions which are keyed to the sectional views (see Figures 1 and 2) and the accompanying parts lists.
10 SERIES OM−05463 NOTE Pump Casing Removal (Figure 2) To service the impeller or seal assembly, disconnect the discharge piping. See Figure 1 and remove the hardware (12, 13 and 14) securing the pump casing to the base (3). Support the pump casing (1) using a suitable hoist and sling, and remove the hardware (17 and 18) securing the pump casing to the intermediate (15). Separate the parts by pulling the casing straight away from the intermediate.
OM−05463 10 SERIES To ease installation of the seal, lubricate the Orings, sleeve and bellows with water or a very small amount of oil, and apply a drop of light lubricating oil on the finished faces. Assemble the seal as follows, (see Figure 3).
