10 SERIES OM−03413 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. neither operator safety nor pump integrity are compromised by the installation. Pumps and related equipment must be installed and operated according to all national, local and industry standards.
10 SERIES OM−03413 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−03413 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. 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 2300 RPM.
10 SERIES OM−03413 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. Since the pressure supplied to the pump is critical to performance and safety, be sure to limit the incoming pressure to 50% of the maximum permissible operating pressure as shown on the pump performance curve.
OM−03413 10 SERIES PREINSTALLATION INSPECTION The pump assembly was inspected and tested before shipment from the factory. Before installation, inspect the pump for damage which may have occurred during shipment. Check as follows: a. Inspect the pump for cracks, dents, damaged threads, and other obvious damage. b. Check for and tighten loose attaching hardware. Since gaskets tend to shrink after drying, check for loose hardware at mating surfaces. c.
SERIES the brake and blocking the wheels before attempting to operate the pump. To ensure sufficient lubrication and fuel supply to the engine, do not position the pump and engine more than 15_ off horizontal for continuous operation. The pump and engine may be positioned up to 30_ off horizontal for intermittent operation only; however, the engine manufacturer should be consulted for continuous operation at angles greater than 15_.
OM−03413 10 SERIES Sealing Since even a slight leak will affect priming, head, and capacity, especially when operating with a high suction lift, all connections in the suction line should be sealed with pipe dope to ensure an airtight seal. Follow the sealant manufacturer’s recommendations when selecting and applying the pipe dope. The pipe dope should be compatible with the liquid being pumped.
10 SERIES OM−03413 DISCHARGE LINES Siphoning Do not terminate the discharge line at a level lower than that of the liquid being pumped unless a siphon breaker is used in the line. Otherwise, a siphoning action causing damage to the pump could result. In low discharge head applications (less than 30 feet (9,1 m)), it is recommended that the bypass line be run back to the wet well, and located 6 inches below the water level or cut-off point of the low level pump.
OM−03413 10 SERIES Figures 4 and 5 show a cross-sectional view of the Automatic Air Release Valve, and a corresponding description of operation. A manual shut-off valve should not be installed in any bypass line. A manual shut-off valve may inadvertently be left closed during operation. A pump which has lost prime may continue to operate without reaching prime, causing dangerous overheating and possible explosive rupture of the pump casing. Personnel could be severely injured.

Air Release Valve Installation If the Air Release Valve is to be installed on a staged pump application, contact the factory for specific installation instructions.
OM−03413 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. liquid in the pump casing. The pump will not prime when dry. Extended operation of a dry pump will destroy the seal assembly. Add liquid to the pump casing when: Do not operate an internal combustion engine in an explosive atmosphere.
OM−03413 10 SERIES Liquid Temperature And Overheating Pump speed and operating condition points must be within the continuous performance range shown on the curve on page E-1. OPERATION The maximum liquid temperature for this pump is 160_ F (71_C). Do not apply it at a higher operating temperature. Overheating can occur if operated with the valves in the suction or discharge lines closed.
OM−03413 10 SERIES 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.
OM−03413 If the pump is equipped with the optional automatic starting system, it is subject to automatic restart. Keep hands and clothing away from the unit to prevent injury during automatic operation. Disconnect the battery before performing any maintenance. Failure to do so may result in serious personal injury. 10 SERIES to operate properly. Make certain that the bearing lubricant is of the proper viscosity and at the correct level (see LUBRICATION in Section E).
10 SERIES OM−03413 TROUBLESHOOTING − SECTION D Review all SAFETY information in Section A. 3. 4. Before attempting to open or service the pump: 1. Familiarize yourself with this manual. 2. Switch off engine ignition and disconnect the positive battery cable TROUBLE PUMP FAILS TO PRIME 5. 6. 7. to ensure that the pump will remain inoperative. Allow the pump to completely cool if overheated. Check the temperature before opening any covers, plates, or plugs. Close the suction and discharge valves.

OM−03413 Remove the intermediate drain plug (32) and drain the lubricant. Clean and reinstall the drain plug. Disengage the hardware (22 and 23) and remove the bearing cap (21), gasket (20), outboard oil seal (24), and bearing shim set (27). Tie and tag the shims, or measure and record their thickness for ease of reassembly. Press the oil seal from the bearing cap. Place a block of wood against the impeller end of the shaft (26), and tap the shaft and assembled bearings from the intermediate.
OM−03413 10 SERIES NOTE If a hot oil bath is used to heat the bearings, both the oil and the container must be absolutely clean. If the oil has been previously used, it must be thoroughly filtered. Heat the bearings to a uniform temperature no higher than 250_F (120_C), and slide the bearings onto the shaft, one at a time, until they are fully seated. This should be done quickly, in one continuous motion, to prevent the bearings from cooling and sticking on the shaft.
