Page 5: Introduction
10 SERIES 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 Mainte- nance manual is designed to help you achieve the best performance and longest life from your Gor- man-Rupp pump. -
Page 6: Safety - Section A
10 SERIES This information applies to 10 Series en- gine driven pumps. Refer to the manual accompanying the engine before at- tempting to begin operation. Because pump installations are seldom identical, this manual cannot possibly provide detailed instructions and pre- cautions for each specific application. - Page 7 OM−05463 Do not operate an internal combustion engine in an explosive atmosphere. When operating internal combustion engines in an enclosed area, make cer- tain that exhaust fumes are piped to the outside. These fumes contain carbon monoxide, a deadly gas that is color- less, tasteless, and odorless.

Page 8: Installation − Section Bpage B
10 SERIES 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. -
Page 9: Positioning Pump
OM−05463 c. Carefully read all tags, decals, and markings on the pump assembly, and perform all duties indicated. d. Check levels and lubricate as necessary. Re- fer to LUBRICATION in the MAINTENANCE AND REPAIR section of this manual and per- form duties as instructed. -
Page 10: Line Configuration
10 SERIES forced type to prevent collapse under suction. Us- ing piping couplings in suction lines is not recom- mended. Line Configuration Keep suction and discharge lines as straight as possible to minimize friction losses. Make mini- mum use of elbows and fittings, which substan- tially increase friction loss. -
Page 11: Suction Line Positioning
OM−05463 If it is necessary to position inflow close to the suc- tion 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. -
Page 12: Bypass Lines
10 SERIES With high discharge heads, it is recommended that a throttling valve and a system check valve be in- stalled in the discharge line to protect the pump from excessive shock pressure and reverse rota- tion when it is stopped. If the application involves a high discharge head, gradually close the discharge throttling valve before stopping the pump. -
Page 13: Operation − Section C
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. 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 per- sonnel as a result of pump failure. -
Page 14: Lines Without A Bypass
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. -
Page 15: Cold Weather Preservation
10 SERIES 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 be- fore stopping. If the application involves a high discharge head, gradually close the discharge throttling valve before stopping the pump. -
Page 16: Troubleshooting − Section Dpage D
10 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. Shut down the engine and take pre- cautions to ensure that the pump will remain inoperative. - Page 17 OM−05463 TROUBLE POSSIBLE CAUSE PUMP STOPS OR Air leak in suction line. FAILS TO DELIVER Lining of suction hose collapsed. RATED FLOW OR PRESSURE Leaking or worn seal or pump gasket. Suction intake not submerged at proper level or sump too small. Impeller or other wearing parts worn or damaged.

Page 18: Preventive Maintenance Schedule
10 SERIES 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. -

Page 24: Pump And Seal Disassembly And Reassembly
OM−05463 PUMP AND SEAL DISASSEMBLY AND REASSEMBLY Review all SAFETY information in Section A. Follow the instructions on all tags, label and de- cals attached to the pump. This pump requires little service due to its rugged, minimum-maintenance design. However, if it be- comes 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... - Page 25 10 SERIES Pump Casing Removal (Figure 2) To service the impeller or seal assembly, discon- nect the discharge piping. See Figure 1 and re- move 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).
- Page 26 OM−05463 To ease installation of the seal, lubricate the O- rings, sleeve and bellows with water or a very small amount of oil, and apply a drop of light lubricating SPRING SPRING RETAINER CENTERING WASHER IMPELLER SHIMS ENGINE STUB SHAFT IMPELLER BELLOWS Figure 3.
- Page 27 10 SERIES Lubricate the seal as indicated in LUBRICATION, after the impeller has been installed. Impeller Installation And Adjustment (Figure 2) Inspect the impeller and replace it if cracked or badly worn. Install the same thickness of impeller shims (4) as previously removed. Apply anti-seize to the shaft threads and screw the impeller onto the shaft until tight.
