Lifting Pump unit weights will vary depending on the mounting and drive provided. Check the shipping tag on the unit packaging for the actual weight, and use lifting equipment with appropriate capacity. Drain the pump and remove all customer‐installed equipment such as suction and discharge hoses or piping before attempting to lift existing, installed units. Attach a rope or chain to the lifting handle on the top of the pump. Do not lift the unit by the power cable or the discharge piping. Customer installed equipment such as rigid discharge piping must be removed before attempting to lift. PAGE B - 2

Positioning the Pump This pump is designed to operate fully or partially submerged; however, it should not be operated dry for extended periods of time.
Extended dry operation will destroy the seal assembly. Never place the pump on loose or soft ground; the pump could sink, preventing water from reaching the impeller (see Figure 3).
Secure and support the pump by the handle on the pump. If the bottom is heavily sludge‐covered, rest the pump on support blocks or suspend it near the surface of the liquid. If the application involves a lot of debris, protect the pump from excessive wear and clogging by suspending it in a perforated bar rel or culvert pipe. See Figure 4 for correct pump installations. The pump is provided with a suction strainer to pre vent large solids from clogging the impeller. Any spherical solids which pass through the strainer will pass through the pump.

PUMP OPERATION
Do not operate this pump where explo sive vapors or flammable material exist. Death or serious injury will result.
This pump is designed to handle dirty water that does not contain large en trained solids. It is not designed to pump volatile, flammable or corrosive materials. Do not attempt to pump any liquids which may damage the pump or endanger personnel as a result of pump failure.
Figure 1. Always Keep Plug End Dry For manual operation, simply plug the power cable into any 115 volt grounded receptacle. It is strong ly recommended that a Ground Fault Interrupter (GFI) type receptacle (or equivalent) be used (see Figure 2).
Always use a three‐prong grounded re ceptacle. It is strongly recommended that a Ground Fault Interrupter (GFI) type receptacle (or equivalent) be used.
Install the pump and piping as described in IN STALLATION, Section B. Manual Operation Each pump is provided with a 30‐foot (3 m) power cable. Never splice the power cable due to safety and warranty considerations. Figure 2. Always Use a Grounded Receptacle Automatic Operation
Never attempt to alter the length or re pair any power cable with a splice. The pump motor and cable must be com pletely waterproof. Damage to the pump or personal injury may result from alter ations. OPERATION
A float switch assembly is available as an option from the factory to provide for automatic operation. Observe the following instructions for automatic operation. 1. Attach the plastic tie on the float switch power cable to the standpipe in the sump at the ap proximate desired liquid level. Do not allow PAGE C - 1
OM-06497
the liquid level to drop below the bottom of the pump motor cover to ensure cooling of the pump motor. 2. The tie is positioned on the cable approxi mately 6 inches (152 mm) below the float. This setting allows approximately 9 inches (229 mm) of liquid rise between pump start/stop. The start/stop interval may be increased by loosening the nut on the plastic tie swivel and extending the float end of the power cable. The liquid level in the sump will increase ap proximately 8 inches (203 mm) between start/ stop intervals for every 6 inches (152 mm) of cable increase. 3. Plug the pump power cable into the female end of the float cable plug. 4. Plug the float cable into a grounded recep tacle. It is strongly recommended that a Ground Fault Interrupter (GFI) type recep tacle (or equivalent) be used (see Figure 2). Operational Checks Check the pump for proper operation when it is first started and periodically thereafter to identify minor problems.
SE SERIES
STOPPING To stop the pump when in manual mode, simply unplug it from the receptacle. After stopping the pump, be sure to perform all required maintenance and preservation procedures.
This pump is equipped with automatic thermal overload protection which will stop the pump if overheating occurs. Unplug the pump and allow it to cool before at tempting to service the pump. When operated in the automatic mode, the pump will stop and start as the iquid level rises and falls. For service or extended stopping, unplug both the pump and float switch from the receptacle. Storage and Cold Weather Preservation After stopping the pump, use the rope or chain at tached to the lifting handle on the pump to remove the pump from the sump. Do not lift the unit by the power cable or the discharge piping. Customer in stalled equipment such as rigid discharge piping must be removed before attempting to lift.
Check the pump for unusual noises or excessive vibration while it is operating. If noise or vibration is excessive, stop the pump and refer to the troubleshooting chart for possible causes. Check the pump strainer screen for clogging caused by stones, sticks, or other debris. Clean the strainer screen when required. In some cases, stopping the pump momentarily may back flush the strainer screen, purging most of the debris from it. If this fails to clean the screen, unplug the pump , remove it from the sump, and remove the debris manually (see MAINTENANCE AND RE PAIR in Section E). 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 neces sary, liquid pressure must be limited to 50% of the maximum permissible operating pressure shown on the pump performance curve (see MAINTE NANCE AND REPAIR, Section E). PAGE C - 2
Do not attempt to lift the pump by the power cable or piping. Attach proper lifting equipment to the handle on the pump. Clean the strainer screen before storage. If the application involves a lot of mud or sludge, remove the strainer and clean the impeller before storage.
NOTE The most common cause of failure to run is hard ened mud or sludge in the impeller. In freezing temperatures, the pump will not freeze as long as it is submerged in liquid. If the pump casing is not submerged, or if the liquid begins to freeze, remove the pump from the sump and allow OPERATION

it to dry thoroughly. Run the pump for two or three minutes to dry the inner walls. If the pump freezes, move it into a warm area until completely thawed, or submerge it into the liquid. If the liquid is near freezing, the pump must be sub merged for an extended period of time. Start the pump and check for shaft rotation. If still frozen, al low additional thawing time before attempting to

PUMP MAINTENANCE AND REPAIR Review all SAFETY information in Section A. Follow the instructions on all tags, label and de cals attached to the pump. The following maintenance and repair instructions are provided separately for each individual pump model, and are keyed to the Pump Model views (see Figures 1 and 2) and the accompanying parts lists. Before attempting to service the pump, unplug the pump power cable to ensure that the pump will re main inoperative.
Before attempting to open or service the pump: 1. Familiarize yourself with this man ual. 2. Unplug the pump power cable to ensure that the pump will remain inoperative. 3. Allow the pump to completely cool if overheated. Use a rope or chain attached to the handle on the pump to remove the pump from the sump and move it to a suitable location for service. It is not necessary to disconnect a flexible discharge hose before removing the pump. If rigid discharge pip ing is used, disconnect the piping before attempt ing to move the pump.
Do not attempt to lift the pump by the power cable or piping. Attach proper lifting equipment to the handle on the pump. Select a suitable location, preferably indoors, to perform the degree of maintenance required. If the motor housing is to be opened, the work must be done in a clean, well‐equipped shop. All mainte nance functions must be done by qualified person nel. PAGE E - 6
Obtain the services of a qualified elec trician to service the electrical compo nents of this pump. Check the chart in TROUBLESHOOTING, Section D, to determine the nature of the pump problem. If the problem is mechanical in nature, such as worn pump parts, seal replacement, etc., refer to the ap propriate PUMP END DISASSEMBLY procedures for your specific pump. Complete disassembly procedures for the pump motor are not included in this manual. Instructions are provided only for replacement of the pump power cable. If the pump fails to run and motor problems are suspected, contact your Gorman‐ Rupp distributor or the factory for motor service. Carefully inspect any O‐rings or gaskets before re moval and cleaning to determine if a proper seal and compression existed prior to disassembly. If sealing was faulty or questionable, the cause must be determined and corrected before reassembly. All gaskets and most O‐rings must be replaced if disturbed. Repair gaskets and O‐rings are avail able as a kit shown on the parts lists.
PUMP END DISASSEMBLY MODEL SE2G54-E.5 115/1 (FIGURE 1) Strainer Removal To remove the strainer (31), lay the pump on its side, disengage the machine screws (35) and re move the strainer. If the impeller is clogged, the de bris can usually be removed without further disas sembly. Impeller Removal Remove the machine screws (29) and separate the pump housing (1) and pump housing O‐ring. To immobilize the shaft, insert a large flat‐blade screwdriver into the slot in the end of the shaft. Strike the impeller (2) in a counterclockwise direc tion with a soft‐faced mallet or wood block and hammer. When the impeller breaks loose, remove MAINTENANCE & REPAIR

the screwdriver and unscrew the impeller from the shaft. Seal Removal
NOTE The seal for this pump consists of two identical seal assemblies installed back‐to‐back in tandem. The two seals are provided for repair under one part number for the mechanical seal kit. Before attempting to remove the seal, remove the machine screw and O‐ring (32 and 6) and drain oil from the seal cavity. Disengage the machine screws (34) and use a pair of flat head screwdrivers to pry the oil chamber cover (30) and oil seal (33) off the shaft as a unit. Use caution when removing the oil chamber cover; the lower seal stationary element and seat will also come off the shaft. Remove the oil chamber gas ket. Invert the oil chamber cover and remove the lower stationary element and seat from the cover. With the oil chamber cover inverted, press the oil seal (38) out of the oil chamber cover from the back side. Lubricate the seal area of the rotor shaft and slide the rotating portions of both the lower and upper seal seal assemblies off the shaft. To remove the stationary portion of the upper seal assembly, slide two stiff wires with hooked ends along the shaft and hook the stationary seat and element from the back side. Pull the stationary por tion of the seal from the bore of the oil chamber (4). Stuff a clean tissue into the stationary seal seat bore or wrap a small rag around the shaft to pre vent contamination of the motor cavity. If no further disassembly is required, proceed with the appropriate PUMP END REASSEMBLY proce dures for your specific pump. Complete disassembly procedures for the pump motor are not included in this manual. Instructions are provided only for replacement of the pump power cable. If the pump fails to run and motor problems are suspected, contact your Gorman‐ Rupp distributor or the factory for motor service. MAINTENANCE & REPAIR
PUMP END REASSEMBLY MODEL SE2G3-E.5 115/1 (FIGURE 1) Cleaning And Inspection Of Pump Parts Carefully inspect any O‐rings or gaskets before re moval and cleaning to determine if a proper seal and compression existed prior to disassembly. If sealing was faulty or questionable, the cause must be determined and corrected before reassembly. Replace any parts as required. It is strongly rec ommended that all seals and gaskets be replaced any time the pump is disassembled. Thoroughly clean all reuseable parts with a soft cloth soaked in cleaning solvent. Remove all O‐ rings and gaskets, and clean the sealing surfaces of dirt or gasket material. Be careful not to scratch gasket surfaces.
Most cleaning solvents are toxic and flammable. Use them only in a well ven tilated area free from excessive heat, sparks, and flame. Read and follow all precautions printed on solvent contain ers. Inspect the rotor shaft (8) for damaged threads, scoring, or nicks. Remove nicks and burrs with a fine file or emery cloth to restore original contours. The shaft seal assembly should not be reused be cause wear patterns on the finished faces cannot be realigned during reassembly. This could result in premature failure. If any components are worn, replace the complete seal; never mix old and new seal parts. Handle a new seal with extreme care to prevent damage. Be careful not to contaminate the preci sion finished faces; even fingerprints on the faces can shorten seal life. If necessary, clean the faces with a non‐oil based solvent and a clean, lint‐free tissue. Wipe lightly in a concentric pattern to avoid scratching the faces. Install the shaft seal as illustrated in Figure 3. PAGE E - 7

Positioning the Pump This pump is designed to operate fully or partially submerged; however, it should not be operated dry for extended periods of time.
Extended dry operation will destroy the seal assembly. Never place the pump on loose or soft ground; the pump could sink, preventing water from reaching the impeller (see Figure 3).
Secure and support the pump by the handle on the pump. If the bottom is heavily sludge‐covered, rest the pump on support blocks or suspend it near the surface of the liquid. If the application involves a lot of debris, protect the pump from excessive wear and clogging by suspending it in a perforated bar rel or culvert pipe. See Figure 4 for correct pump installations. The pump is provided with a suction strainer to pre vent large solids from clogging the impeller. Any spherical solids which pass through the strainer will pass through the pump.

PUMP OPERATION
Do not operate this pump where explo sive vapors or flammable material exist. Death or serious injury will result.
This pump is designed to handle dirty water that does not contain large en trained solids. It is not designed to pump volatile, flammable or corrosive materials. Do not attempt to pump any liquids which may damage the pump or endanger personnel as a result of pump failure.
Figure 1. Always Keep Plug End Dry For manual operation, simply plug the power cable into any 115 volt grounded receptacle. It is strong ly recommended that a Ground Fault Interrupter (GFI) type receptacle (or equivalent) be used (see Figure 2).
Always use a three‐prong grounded re ceptacle. It is strongly recommended that a Ground Fault Interrupter (GFI) type receptacle (or equivalent) be used.
Install the pump and piping as described in IN STALLATION, Section B. Manual Operation Each pump is provided with a 30‐foot (3 m) power cable. Never splice the power cable due to safety and warranty considerations. Figure 2. Always Use a Grounded Receptacle Automatic Operation
Never attempt to alter the length or re pair any power cable with a splice. The pump motor and cable must be com pletely waterproof. Damage to the pump or personal injury may result from alter ations. OPERATION
A float switch assembly is available as an option from the factory to provide for automatic operation. Observe the following instructions for automatic operation. 1. Attach the plastic tie on the float switch power cable to the standpipe in the sump at the ap proximate desired liquid level. Do not allow PAGE C - 1

the liquid level to drop below the bottom of the pump motor cover to ensure cooling of the pump motor. 2. The tie is positioned on the cable approxi mately 6 inches (152 mm) below the float. This setting allows approximately 9 inches (229 mm) of liquid rise between pump start/stop. The start/stop interval may be increased by loosening the nut on the plastic tie swivel and extending the float end of the power cable. The liquid level in the sump will increase ap proximately 8 inches (203 mm) between start/ stop intervals for every 6 inches (152 mm) of cable increase. 3. Plug the pump power cable into the female end of the float cable plug. 4. Plug the float cable into a grounded recep tacle. It is strongly recommended that a Ground Fault Interrupter (GFI) type recep tacle (or equivalent) be used (see Figure 2). Operational Checks Check the pump for proper operation when it is first started and periodically thereafter to identify minor problems.
SE SERIES
STOPPING To stop the pump when in manual mode, simply unplug it from the receptacle. After stopping the pump, be sure to perform all required maintenance and preservation procedures.
This pump is equipped with automatic thermal overload protection which will stop the pump if overheating occurs. Unplug the pump and allow it to cool before at tempting to service the pump. When operated in the automatic mode, the pump will stop and start as the iquid level rises and falls. For service or extended stopping, unplug both the pump and float switch from the receptacle. Storage and Cold Weather Preservation After stopping the pump, use the rope or chain at tached to the lifting handle on the pump to remove the pump from the sump. Do not lift the unit by the power cable or the discharge piping. Customer in stalled equipment such as rigid discharge piping must be removed before attempting to lift.
Check the pump for unusual noises or excessive vibration while it is operating. If noise or vibration is excessive, stop the pump and refer to the troubleshooting chart for possible causes. Check the pump strainer screen for clogging caused by stones, sticks, or other debris. Clean the strainer screen when required. In some cases, stopping the pump momentarily may back flush the strainer screen, purging most of the debris from it. If this fails to clean the screen, unplug the pump , remove it from the sump, and remove the debris manually (see MAINTENANCE AND RE PAIR in Section E). 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 neces sary, liquid pressure must be limited to 50% of the maximum permissible operating pressure shown on the pump performance curve (see MAINTE NANCE AND REPAIR, Section E). PAGE C - 2
Do not attempt to lift the pump by the power cable or piping. Attach proper lifting equipment to the handle on the pump. Clean the strainer screen before storage. If the application involves a lot of mud or sludge, remove the strainer and clean the impeller before storage.
NOTE The most common cause of failure to run is hard ened mud or sludge in the impeller. In freezing temperatures, the pump will not freeze as long as it is submerged in liquid. If the pump casing is not submerged, or if the liquid begins to freeze, remove the pump from the sump and allow OPERATION

it to dry thoroughly. Run the pump for two or three minutes to dry the inner walls. If the pump freezes, move it into a warm area until completely thawed, or submerge it into the liquid. If the liquid is near freezing, the pump must be sub merged for an extended period of time. Start the pump and check for shaft rotation. If still frozen, al low additional thawing time before attempting to

The following maintenance and repair instructions are provided separately for each individual pump model, and are keyed to the Pump Model views (see Figures 1 and 2) and the accompanying parts lists. Before attempting to service the pump, unplug the pump power cable to ensure that the pump will re main inoperative.
Before attempting to open or service the pump: 1. Familiarize yourself with this man ual. 2. Unplug the pump power cable to ensure that the pump will remain inoperative. 3. Allow the pump to completely cool if overheated. Use a rope or chain attached to the handle on the pump to remove the pump from the sump and move it to a suitable location for service. It is not necessary to disconnect a flexible discharge hose before removing the pump. If rigid discharge pip ing is used, disconnect the piping before attempt ing to move the pump.
Do not attempt to lift the pump by the power cable or piping. Attach proper lifting equipment to the handle on the pump. Select a suitable location, preferably indoors, to perform the degree of maintenance required. If the motor housing is to be opened, the work must be done in a clean, well‐equipped shop. All mainte nance functions must be done by qualified person nel. PAGE E - 6
Obtain the services of a qualified elec trician to service the electrical compo nents of this pump. Check the chart in TROUBLESHOOTING, Section D, to determine the nature of the pump problem. If the problem is mechanical in nature, such as worn pump parts, seal replacement, etc., refer to the ap propriate PUMP END DISASSEMBLY procedures for your specific pump. Complete disassembly procedures for the pump motor are not included in this manual. Instructions are provided only for replacement of the pump power cable. If the pump fails to run and motor problems are suspected, contact your Gorman‐ Rupp distributor or the factory for motor service. Carefully inspect any O‐rings or gaskets before re moval and cleaning to determine if a proper seal and compression existed prior to disassembly. If sealing was faulty or questionable, the cause must be determined and corrected before reassembly. All gaskets and most O‐rings must be replaced if disturbed. Repair gaskets and O‐rings are avail able as a kit shown on the parts lists.

NOTE The seal for this pump consists of two identical seal assemblies installed back‐to‐back in tandem. The two seals are provided for repair under one part number for the mechanical seal kit. Before attempting to remove the seal, remove the machine screw and O‐ring (32 and 6) and drain oil from the seal cavity. Disengage the machine screws (34) and use a pair of flat head screwdrivers to pry the oil chamber cover (30) and oil seal (33) off the shaft as a unit. Use caution when removing the oil chamber cover; the lower seal stationary element and seat will also come off the shaft. Remove the oil chamber gas ket. Invert the oil chamber cover and remove the lower stationary element and seat from the cover. With the oil chamber cover inverted, press the oil seal (38) out of the oil chamber cover from the back side. Lubricate the seal area of the rotor shaft and slide the rotating portions of both the lower and upper seal seal assemblies off the shaft. To remove the stationary portion of the upper seal assembly, slide two stiff wires with hooked ends along the shaft and hook the stationary seat and element from the back side. Pull the stationary por tion of the seal from the bore of the oil chamber (4). Stuff a clean tissue into the stationary seal seat bore or wrap a small rag around the shaft to pre vent contamination of the motor cavity. If no further disassembly is required, proceed with the appropriate PUMP END REASSEMBLY proce dures for your specific pump. Complete disassembly procedures for the pump motor are not included in this manual. Instructions are provided only for replacement of the pump power cable. If the pump fails to run and motor problems are suspected, contact your Gorman‐ Rupp distributor or the factory for motor service. MAINTENANCE & REPAIR
PUMP END REASSEMBLY MODEL SE2G3-E.5 115/1 (FIGURE 1) Cleaning And Inspection Of Pump Parts Carefully inspect any O‐rings or gaskets before re moval and cleaning to determine if a proper seal and compression existed prior to disassembly. If sealing was faulty or questionable, the cause must be determined and corrected before reassembly. Replace any parts as required. It is strongly rec ommended that all seals and gaskets be replaced any time the pump is disassembled. Thoroughly clean all reuseable parts with a soft cloth soaked in cleaning solvent. Remove all O‐ rings and gaskets, and clean the sealing surfaces of dirt or gasket material. Be careful not to scratch gasket surfaces.
Most cleaning solvents are toxic and flammable. Use them only in a well ven tilated area free from excessive heat, sparks, and flame. Read and follow all precautions printed on solvent contain ers. Inspect the rotor shaft (8) for damaged threads, scoring, or nicks. Remove nicks and burrs with a fine file or emery cloth to restore original contours. The shaft seal assembly should not be reused be cause wear patterns on the finished faces cannot be realigned during reassembly. This could result in premature failure. If any components are worn, replace the complete seal; never mix old and new seal parts. Handle a new seal with extreme care to prevent damage. Be careful not to contaminate the preci sion finished faces; even fingerprints on the faces can shorten seal life. If necessary, clean the faces with a non‐oil based solvent and a clean, lint‐free tissue. Wipe lightly in a concentric pattern to avoid scratching the faces. Install the shaft seal as illustrated in Figure 3. PAGE E - 7
