INSTALLATION - SECTION B

GENERAL INFORMATION
Review all SAFETY information in Section A.
Since pump installations are seldom identical, this section is intended only to summarize general rec ommendations and practices required to inspect, position, and arrange the pump and piping. If there are any questions concerning your specific instal lation, contact your Gorman‐Rupp distributor or the Gorman‐Rupp Company.
The pump motor is not designed to be operated in air for more than 10 minutes without overheating. The pump must be operated through a liquid level control de signed to cut off power when liquid falls be low the midpoint of the motor housing (single pump operation), or below the dis charge flange (duplex, alternating pump operation).
Controls, liquid level devices, and a guide rail sys tem are available from Gorman‐Rupp as optional equipment. For more information on installing and operating these options, refer to the other literature accompanying the option(s).
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested be fore shipment from the factory. Before installation, check for damage which may have occurred dur ing shipment. Check as follows:
a. Inspect the pump assembly for cracks, dents,
damaged threads, and other obvious dam age.
b. Check for loose attaching hardware. Since
gaskets tend to shrink after drying, check for loose hardware at the mating surfaces.
c. Inspect the power cable for cuts or any other
obvious damage.
d. Check that amperes, phase, voltage and
hertz indicated on the name plate match the ratings on the control box and incoming pow er.
e. Carefully read all tags, decals, and markings
on the pump, and perform all duties indicated.
f. Check for oil leaks. If there is any indication of
an oil leak, see LUBRICATION at the end of this manual.
LUBRICATION
These pumps are equipped with two separate mechanical seals.
The seals prevent the liquid being pumped from entering the seal housing cavity from the pump end, and at the same time prevents the oil in the seal housing from leaking into the motor housing.
The upper pump seal is lubricated by oil in the seal housing (see LUBRICATION at the end of this manual). The lower seal is lubricated by the medi um being pumped.
There is no other lubrication required for these pumps.
Pump Motor Specifications
The motor furnished with this pump is an air‐filled, 60 Hz., Squirrel Cage, Induction Start model; NEMA Class H Insulation Rated 356_F (180_C), 104_F (40_C) ambient, plus 252_F (140_C) tem perature rise. The motor is approved for Class 1, Division 1, Group C and D locations.

PUMP INSTALLATION
When installing or servicing the pump or controls, follow all requirements for the installation of wiring or electrical equipment in hazardous locations as outlined in the National Electric Code. When entering the pump wet well for in stallation or service, follow all safety re quirements for confined space entry. Failure to observe these requirements could result in injury or death to person nel.
Do not allow the free end of the power
cable to enter the liquid being pumped. The free end of the cable must be kept dry to prevent liquid from wicking through the cable and into the motor.
NOTE
Refer to the performance curve on the pump Spe cification Data Sheet when determining the most ef ficient piping installation. The recommended
maximum submergence depth is 65 feet.
Lifting
Death or serious personal injury and damage to the pump or components can occur if proper lifting procedures are not observed. Make certain that hoists, chains, slings or cables are in good working condition and of suffi cient capacity and that they are posi tioned so that loads will be balanced and the pump or components will not be damaged when lifting. Do not attempt to lift this pump by the motor or control cables, or the piping. Attach proper lift ing equipment to the lifting bail fitted on the pump. Lift the pump or component
PAGE B - 2 INSTALLATION

only as high as necessary and keep per sonnel away from suspended objects.
Pump unit weights will vary depending on the pump application. 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 equip ment such as discharge hoses or piping before at tempting to lift existing, installed units.
Impeller Rotation
Check impeller rotation as follows before installing the pump on rails or in a wet well.
While checking impeller rotation, secure the pump to prevent the motor power cable from coiling.
Suspend the pump by the lifting handle. Apply power briefly and note the direction of pump kick back. As viewed from the top, the pump should kick in a counterclockwise direction; this will indi cate that impeller rotation is correct.
If the pump kicks in a clockwise direction, impeller rotation is incorrect. If the pump is powered by a three‐phase motor, have a qualified electrician in terchange the control box connections of any two pump motor power leads. Re‐check pump kick back; it should now be in a counterclockwise direc tion.
If rotation is incorrect on a single‐phase motor, con tact the factory before installing the pump.
Positioning the Pump (Guide Rail Application)
If the pump is to be installed where flam mable vapors may be present, the guide rail system must be of a non‐sparking design suitable for explosion‐proof ser vice. Failure to observe this require ment could result in injury or death to personnel.
The pump may equipped with a guide shoe for mounting on optional guide rails. A discharge el bow/baseplate is also available as optional equip ment.
Use a suitable lifting device attached to the lifting handle to lift the pump. Engage the guide shoe at the top of the guide rails, and lower the pump into the sump. When lowered into place, the guide shoe connects to the optional discharge elbow/ baseplate, and the pump is automatically and se curely sealed to the piping system; the pump can be removed or installed without personnel entering the wet well.
For information on installing the guide rails, see the literature accompanying the rails. Be sure the in stallation allows the pump to slide without binding on the rails or baseplate.
NOTE
When engaging the guide shoe and elbow/base plate, make sure that the connection is not impeded by mounting hardware, and that the guide shoe is fully seated in the baseplate.
Reel in any slack control cable so that it is not dragged into the pump suction.
Positioning the Pump (Stand Application)
Secure a discharge hose to the pump discharge connection, and use a suitable lifting device at tached to the lifting handle to lower the pump into the wet well. The recommended maximum sub
mergence depth is 65 feet.
Make certain that the pump and stand sit level in the wet well.
Reel in any slack control cable so that it is not dragged into the pump suction.
Piping
The optional discharge elbow/baseplate is drilled for connection to a discharge flange for slide rail applications. Either hose or rigid pipe may be used to make discharge connections.
If rigid discharge piping is installed, the line must be independently supported to avoid vibration and strain on the pump. For maximum pumping capac ity, keep the line as short and straight as possible. Elbows and fittings used in discharge lines in crease friction loss; minimize their use.
PAGE B - 3INSTALLATION
Page 13
SF SERIES X‐PROOF PUMPS OM-06629
It is recommended that a check valve or throttling valve be installed in the discharge line to control si phoning or back flow when the pump is shut off.
ELECTRICAL CONNECTIONS
Install and operate this pump in accor dance with the National Electrical Code and all local codes. Have a qualified electrician perform all checks and con nections in this section. Never attempt to alter the length of the pump motor cable or to repair it with a splice. The power cable and pump mo tor must be kept completely waterproof. Serious damage to the pump and injury or death to personnel can result from any alteration to the cable.
Field Wiring Connections (Incoming Power)
Do not connect the pump motor directly to the incoming power lines. The pump motor is designed to operate through a control box which provides overload protection and power control; other wise, the pump warranty will be voided. Make certain that the pump and control box are properly grounded, and that the incoming power matches the require ments of the pump and controls. Install and operate the control box in accor dance with the National Electric Code and all local codes. Failure to follow these could result in injury or death to personnel.
Field wiring is not provided with this pump, and must be supplied by the user. The field wiring must be of the proper size and type to ensure an ade quate voltage supply to the pump. Voltage avail able at the motor must be within the range indi cated in Table B‐2.

If the test circuit does not close, there is a defect in the cable or motor which must be corrected.
Control Box Connections
The motor powering this pump is ap proved by both CSA and FM for Class 1, Division 1, Groups C and D environ ments. Any liquid level devices used with the pump must be intrinsically safe for use in these environments. Any control box used to operate the pump must meet all applicable local and national codes for the application. If the control box is to be installed in an ex plosive environment, it must be a Nema 7 rating or better. If a non‐explosion proof control box is used, it must be lo cated outside the explosive environ ment. Improper location of a non‐explo sion proof control box could result in de struction of equipment, injury, or death to personnel.
This pump is shipped completely wired for the volt age shown on the nameplate and is ready for op eration through an approved control box.
Ground the control box in accordance with the in structions accompanying it.
Refer to Figure B-1 and connect the pump motor cable to the control box.
Figure B-1. Three Phase Power

SF SERIES X‐PROOF PUMPS OM-06629
Refer to the appropriate wiring diagram accompa nying the control box when making electrical con nections.
Liquid Level Devices
Optional controls available from Gorman‐Rupp may provide a means to automatically regulate the liquid level. These control boxes may be con nected to the following sensing devices which per form either filling or dewatering functions (see Fi gure B-3).
The internal wiring of the sensing devices are different for filling and dewatering func tions. Be sure to follow the instructions in cluded with the option before making con nections.
S Diaphragm Type: two fixed‐position sen
sors (upper and lower) each contain a dia phragm which flexes with changes in liquid level, thus activating an enclosed miniature switch.
S Bulb (Float) Type: a bulb raises or lowers
(floats) with the liquid level, thus activating an enclosed miniature switch.
Other types of liquid level devices may also be used. Consult the factory for the liquid level device best suited for your application.
Liquid level devices must be positioned far enough to allow 6 minutes between starts. If the pump motor cycles more than 10 starts per hour, it will over‐heat, resulting in damage to the motor windings or control box components.

During motor shutoff by the thermal overload device, control box circuits re main live. Do not attempt to service any control box components unless incom ing power has been shut off.
After stopping the pump, be sure to perform all re quired maintenance and preservation procedures.
Operational Checks
STARTING, STOPPING, AND OPERATIONAL CHECKS
Starting
Do not attempt to operate the pump until impeller rotation has been checked; im proper rotation will affect pump perform ance and may damage the pump.
Follow the instructions accompanying the control box, start the pump, and run any recommended checks.
Stopping
Follow the instructions accompanying the control box for stopping the pump.
To detect minor problems, check the pump for proper operation when it is first started, and at peri odic intervals during operation.
To avoid serious damage to the pump, check for unusual noises or excessive vi bration while the pump is running. If noise or vibration is excessive, stop operation and refer to the troubleshooting chart in Section D.
The suction inlet or impeller may become clogged with debris. In some cases, stopping the pump momentarily may backflush this blockage. If back flushing does not clear the debris, remove the pump from the sump or wet well and clear manu ally.
Never introduce air or steam pressure The integral thermal overload device will shut off the motor if the temperature rises above design limits. When the pump cools and the temperature falls below these limits, the motor will restart automatically. To avoid the hazards of an unexpected motor start‐up, do not at

liquid pressure input to 50% of the maxi
mum permissible operating pressure
shown in the pump performance curve
Page 18
OM-06629 SF SERIES X‐PROOF PUMPS
(refer to the pump Specification Data Sheet).
Check the pump for overheating. Overheating can occur if the pump is misapplied, required to start repeatedly, if the control box fails to provide over load or thermal protection, or if the pump is oper ated against a closed discharge valve for an ex tended period of time.
Do not start the pump more than 10 times per hour. If the motor does not cool be tween starts it will overheat, resulting in damage to the motor windings or control box components.
Do not attempt to thaw the pump by us ing a torch or other source of flame. This could damage O‐rings or heat the oil in the seal housing above critical tempera tures, causing the pump to rupture or explode.
LUBRICATION
Before installing or removing the lubrica
tion plugs, always make sure the pump is
completely cool, and clean the area
around the plugs to prevent contamination
of the oil.
Check the oil level in the seal cavity before initial
startup, after the first two weeks of operation, and
every month thereafter.
Check the oil level only when the pump
is cool. If the oil level plug is removed
when the pump is hot, pressure in the
seal cavity can cause hot oil to be
ejected as the plug is removed.
Draining Oil
Lay the pump flat on a work surface with one of the
lubrication plugs facing up. Remove the plug slow
ly to release any pressure in the seal housing.
COLD WEATHER PRESERVATION
The pump will not freeze as long as the casing is submerged in liquid. If the casing is not sub merged, or if the liquid begins to freeze, remove the pump from the sump or wet well and dry it thor oughly. Run the pump for two or three minutes to dry the inner walls.
If the pump does freeze while it is out of the liquid, submerge it until thawed; if the liquid is near freez ing, the pump must be submerged for an extended period of time. Check thawing by starting the pump and checking that the shaft rotates freely. If the pump remains frozen, allow additional thawing time before attempting to restart.
If submerging does not thaw the pump, move it into a warm area until completely thawed.
Place a clean container under the other (lower)
plug. Remove the plug and roll the pump on its side
to drain the seal housing.
Condition Of Oil
Check the condition of the oil drained from the
pump. Clear oil indicates that the lower pump seal
is functioning properly. If the oil is milky or contains
water, the lower seal must be changed before the
pump is put back in operation.
Adding Oil
Remove the lubrication plugs as indicated in
Draining Oil. Position the pump upright and add
premium quality submersible pump oil through
one of the plug holes until the oil reaches the bot
tom of the hole. Clean and re‐install the plugs.

ELECTRICAL TESTING
Make the electrical checks which follow to deter mine if pump malfunctions are being caused by problems in the motor or in the power cable.
Test Equipment
A volt/amp/ohmmeter and megohmmeter of ade quate range and quality are required to conduct the electrical tests which follow. Use commercially available equipment as listed below.
Equipment Use
Ammeter To check AC Voltage
and current (amperage)
Ohmeter To measure resistance
(ohms) to ground
can be measured. If possible, measure the voltage at the control box with:
1. The pump off.
2. The pump running in air.
3. The pump submerged and running under full load.
The voltage measured under each condition must be the same.
b. If voltage is balanced when the pump is off but
is imbalanced when the pump is running, thoroughly check the power source, all inter connecting cables, and the pump motor to isolate the defect.
c. Use an Amprobe or equivalent instrument to
measure the current draw (amperage) of each phase while the pump is running under full load, and with no load. In each condition, the amperage readings for all three phases must match as closely as can be measured. Normal amperage values are listed in Table 1, Section B; these values apply only when the voltage at the site is the normal voltage listed.
Refer to the wiring diagram(s) accompany ing the motor and control box before re connecting any electrical leads which have been disconnected. Connections to the wrong terminals may damage the motor and/or control devices.
Voltage Imbalance
Use a voltmeter to read each phase of the incom ing 3‐phase power. Each phase must balance with the other two as closely as can be measured with a commercial instrument. If the phases are out of balance, contact your power company. If the phases are balanced, check out the motor as de scribed in the following steps:
a. Use a voltmeter, Amprobe, or equivalent in
strument to read the voltage of incoming power lines 1 and 2, 2 and 3, and 1 and 3 at the control box. Voltage must match as closely as
TROUBLESHOOTING PAGE D - 3
Motor and Power Cable Continuity
Set the megohmmeter at R x 1 scale and zero‐ balance it. Test as follows:
a. Shut off incoming power to the control box,
and disconnect the motor power cable leads. Connect the megohmmeter test leads to any two power cable leads, and note the megohm meter reading. A high resistance reading indi cates an open or broken circuit in the power cable or motor windings, or a bad connection between the motor and cable.
b. Repeat Step a. with each set of leads. The
three readings should be as close as can be measured.
c. If readings indicate that continuity problems
exist in the motor or power cable, the motor must be returned to the factory or to a Gor man‐Rupp authorized repair facility.
Page 23
SF SERIES X‐PROOF PUMPS OM-06629
Insulation Resistance
Set the megohmmeter at R x 100, and zero‐ba lance it. Test as follows:
a. Shut off incoming power to the control box,
and disconnect the motor power cable leads. Connect one megohmmeter test lead to the motor cable green/yellow ground lead. Touch the other test lead to each of the motor cable leads in turn. Note the readings.
b. Readings will indicate resistance values in
both the power cable and motor windings.If resistance reads infinity (1), insulation is good. If resistance reads between infinity (1), and 1 megohm, insulation is acceptable but should be rechecked regularly. If resistance reads less than 1 megohm, insulation should be checked more closely and frequently.
c. If readings indicate that a ground exists, the
motor must be returned to the factory or to a Gorman‐Rupp authorized repair facility.

PUMP END DISASSEMBLY AND REASSEMBLY

SF SERIES X‐PROOF PUMPSOM-06629
Review all SAFETY information in Section A.
This manual will alert personnel to known proce dures which require special attention, to those which could damage equipment, and to those which could be dangerous to personnel. However, this manual cannot possibly anticipate and provide detailed precautions for every situation that might occur during maintenance of the unit. Therefore, it is the responsibility of the owner/maintenance per sonnel to ensure that only safe, established main tenance procedures are used, and that any proce dures not addressed in this manual are performed only after establishing that neither personal safety nor pump integrity are compromised by such prac tices.
Do not attempt to service the pump as sembly unless all power to the motor has been shut off at the control box; otherwise, injury or death could result.
If the pump is used to handle liquids which may cause illness or disease through direct exposure, take neces sary precautions during maintenance and repair to prevent personal contam ination.
Select a suitable location, preferably indoors, to perform required maintenance. All work must be performed by qualified personnel.
Check the chart in TROUBLESHOOTING, Section D of this manual, to determine the nature of the pump problem. If the problem is mechanical in na ture, such as worn pump parts, seal replacement, lubrication, etc., refer to the following instructions.
If the problem is electrical, maintenance may be performed only by a Gorman‐Rupp authorized re pair facility, or the factory. Otherwise, the pump warranty will be negated, and damage to the pump, and injury or death to personnel can result. Contact the factory for the authorized repair facility closest to you.
Death or serious personal injury and damage to the pump or components can occur if proper lifting procedures are not observed. Make certain that hoists, chains, slings or cables are in good working condition and of suffi cient capacity and that they are posi tioned so that loads will be balanced and the pump or components will not be damaged when lifting. Do not attempt to lift this pump by the motor or control cables, or the piping. Attach proper lift ing equipment to the lifting bail fitted on the pump. Lift the pump or component only as high as necessary and keep per sonnel away from suspended objects.
The electrical power used to operate this pump is high enough to cause inju ry or death. Make certain that the control handle on the control box is in the off po sition and locked out, or that the power supply to the control box has been otherwise cut off and locked out, before attempting to open or service the pump assembly. Tag electrical circuits to pre vent accidental start‐up.
Carefully inspect any O‐rings before removal and cleaning to determine if a proper seal and com pression existed prior to disassembly. If sealing was faulty or questionable, the cause must be de termined and corrected before reassembly. All O‐ rings must be replaced if disturbed.

PUMP END DISASSEMBLY
Preparing Pump for Disassembly
Use the hoisting bail to remove the pump from the wet well or sump, and move it to a suitable location for disassembly.
If the pump is designed for a guide rail application, it is not necessary to remove the guide shoe for most pump maintenance procedures. If removal of the guide shoe is desired, disengage the hardware securing the guide shoe to the pump casing and remove the guide shoe and guide shoe seal.
If the pump is designed for a stand application, dis engage the hardware securing the pump to the stand before proceeding with pump maintenance.
Suction Head and Wear Ring Removal
Position the pump horizontally on a flat work sur face and remove the hardware securing the suc tion head to the pump casing.
Use a pair of suitable tools to pry the suction head and assembled wear ring out of the pump casing.
Remove the O‐ring from the outer shoulder of the seal plate.
Draining Oil From Seal Cavity
The seal cavity oil must be drained to prevent the oil from escaping as the impeller is removed.
Let the pump cool before removing the seal cavity drain plug. Pressure built up within a hot pump could cause the oil to spray out when the plug is removed. Re move the plug slowly and permit pressure to vent to atmosphere.
Lay the pump on its side with one of the pipe plugs facing up. Clean any dirt from around the plug. Re move the plug slowly to release any pressure and install a short pipe nipple in the hole. Roll the pump and drain the seal oil into a clean container. In spect the oil for water, dirt, or cloudy condition which could indicate lower seal failure or poor O‐ ring seal.
Impeller Removal
Inspect the wear ring for excessive wear or scoring. If replacement is required, install two M12 x 1.75 x 76 mm long capscrews (not supplied) in the tapped holes in the suction head. Turn the screws evenly in an alternating sequence to press the wear ring out of the suction head.
Pump Casing Removal
Position the pump assembly on a flat surface and use the lifting bail and lifting device to support the pump in a vertical position. Remove the hardware securing the motor assembly to the pump casing.
Using the lifting device, raise the motor assembly out of the pump casing. It may be necessary to tap around the circumference of the pump casing with a soft‐faced mallet to break the seal between the casing and motor. When the motor is free of the pump casing, position the motor and remaining pump end components horizontally on a flat sur face for further disassembly. Chock the pump to prevent rolling when positioned horizontally.
Wedge a soft metal rod between the impeller vanes to prevent impeller rotation.
NOTE
A strap wrench may also be used to immobilize the impeller.
Remove the impeller capscrew. A hex key used in conjunction with an impact wrench can also be used to remove the impeller screw.
Remove the impeller washer. Remove the metal rod or strap wrench used to immobilize the im peller.
To remove the impeller, use two thin‐bladed screw drivers positioned 180_ apart to pry on the back of the impeller and “walk” the impeller off the shaft. Use increasingly larger screwdrivers (or wedges) as necessary. After the impeller comes free of the shaft, retain the impeller key.
Remove the impeller adjusting shims. Tie and tag the shims for ease of reassembly.

If no further disassembly is required, proceed to the appropriate areas in PUMP END REASSEMB
LY.
Seal Removal
Carefully remove the spring retainer (if so equipped) and seal spring. Slide the shaft sleeve and rotating portion of the seal off the shaft as a unit.
Apply oil to the sleeve and work it up under the rub ber bellows. Slide the rotating portion of the seal off the shaft sleeve.
Work a pair of stiff wires with hooked ends between the rotor shaft and the stationary seat and pull the stationary seat and O‐ring out of the seal plate.
NOTE
An alternate method of removing the stationary ele ment is to remove the screws securing the seal plate to the motor assembly. Pry the assembled seal plate and stationary element off the shoulder of the intermediate. Remove the O‐ring and press the stationary element and seat out of the seal plate from the back side.
Remove the seal sleeve O‐ring from the rotor shaft.

Cleaning and Inspection of Pump Parts
With the pump inverted, stuff a clean tissue into the stationary seal seat bore of the intermediate or wrap a small rag around the shaft to prevent for eign material from entering the motor cavity.
Carefully inspect any O‐rings before removal and cleaning to determine if a proper seal existed prior to disassembly. If sealing was faulty or question able, the cause must be determined and corrected before reassembly. Replace any parts as required.
Thoroughly clean all reuseable parts with a soft cloth soaked in cleaning solvent. Remove all O‐ rings and clean the sealing surfaces.

PUMP END REASSEMBLY
NOTE
Reuse of old O‐rings or shaft seal parts will result in premature leakage or reduced pump performance. It is strongly recommended that new O‐rings and a new shaft seal be used during reassembly (see the parts lists for part numbers).
Hardware Torque Values
When reassembling the pump, use the following table to determine the proper torque values for hardware.
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 for damaged threads, scor ing, or nicks. Remove nicks and burrs with a fine file or hand honing stone to restore original con tours. If the shaft is bent or severely damaged, the motor must be replaced.

Seal Installation
Thoroughly clean the O‐ring surfaces and seal bore of the seal plate. The seal bore must be free of burrs and nicks which could damage the seal. In spect the seal plate for cracks, distortion, or ero sion and replace it if defective.
Lubricate the seal sleeve O‐ring with light oil and slide it onto the rotor shaft until it is seated against the shaft shoulder. Use caution not to nick or dam age the O‐ring on the shaft keyway.

Position the seal plate on a clean flat surface with the impeller side up.
Unpack the seal stationary seat and O‐ring. Apply a light coating of oil to the seal plate bore and the O.D. of the stationary seat O‐ring. Keep the sealing face dry.
Position the stationary seat and O‐ring in the seal plate bore with the sealing face up and cover the seal face with a clean tissue. Use your thumbs to press the assembly into the bore. Apply equal pressure on opposite sides until the seat contacts the bore shoulder. Remove the tissue and inspect the seal face to ensure that it is clean and dry. If cleaning is necessary, use clean tissue to wipe
lightly in a circular pattern.

above. Remove the tissue and inspect the seal face to ensure that it is clean and dry.
Install a new O‐ring on the shoulder of the interme diate.
Carefully position the seal plate and stationary seal components on the rotor shaft. Align the holes in the seal plate for the capscrews with those in the intermediate and slide the seal plate onto the shaft until fully seated against the intermediate. Be care ful not to damage the stationary seat already installed in the seal plate. Secure the seal plate to the intermediate with the flat head capscrews.
Unpack the rotating portion of the seal. Be certain the seal face of the rotating element is free of grit or surface damage. Because the rotating element may not stay in the bellows retainer when turned upside down, place a small amount of grease at equal spaces on the back of the element and posi tion it in the bellows retainer. The grease should hold the element in position until the seal is in stalled. Assemble the drive grooves of the rotating element into the drive lugs of the bellows retainer.
Lubricate the I.D. of the bellows with water and slide the rotating subassembly over the shaft sleeve until the seal face is just flush with the under cut end of the sleeve.
Slide the assembled shaft sleeve and rotating por tion of the seal and onto the rotor shaft until the pol ished faces contact. Continue to push the sleeve through the seal until it is fully seated against the shaft shoulder.
Install the seal spring over the bellows retainer and install the spring retainer (if so equipped). See Fig ure E-2 for proper order of seal assembly.
shaft until seated firmly against the impeller shim set. If your pump is not equipped with a spring re tainer, make sure the seal spring seats squarely over the shoulder on the back of the impeller.
A clearance of .020 to .040 inch (0,51 to 1,02 mm) between the impeller and the seal plate is recom mended for maximum pump efficiency. Measure this clearance and add or remove impeller adjust ing shims as required.
After the impeller is installed, coat the threads of the rotor/shaft or impeller capscrew with `Loctite Threadlocker No. 242' or equivalent compound. Install the impeller washer. Wedge a soft metal bar between the vanes of the impeller or use a strap wrench to prevent shaft rotation. Torque the im peller nut or capscrew to the value shown in Table E-1.
Remove the metal bar or strap wrench used to pre vent shaft rotation and turn the impeller to check for free rotation.
Suction Head and Wear Ring Installation
The suction head and wear ring must be installed in the pump casing before installing the pump cas ing in order to set the impeller‐to‐wear ring clear ance.
If the wear ring was removed from the suction head, position the replacement wear ring in the suction head bore and use an arbor (or hydraulic) press to press the wear ring into the suction head until fully seated.
Install a new O‐ring on the shoulder of the suction head. Position the suction head against the pump casing and use the previously removed hardware to press the suction head into the pump casing.
Impeller Installation
Inspect the impeller for cracks, broken vanes, or wear from erosion and replace it if damaged. Clean the threads on the rotor shaft for the impeller nut.
Install the same thickness of adjusting shims as previously removed. Install the impeller key in the rotor shaft keyway. Align the keyway in the impeller with the shaft key and push the impeller onto the
Adjust the impeller‐to‐wear ring clearance after installing the pump casing as described below.
Pump Casing Installation
Install a new O‐ring on the shoulder of the seal plate. Slide the pump casing over the seal plate shoulder until fully seated. Apply “Never‐Seez” or equivalent compound to the capscrews and se cure the pump casing to the seal plate and motor assembly with the previously removed hardware.

Torque the capscrews to the value shown in Table E-1.
Impeller Face Clearance Adjustment
A clearance of .006 to .012 inch (15 to 30 mm) be tween the face of the impeller and the wear ring is recommended for maximum pump efficiency.
Loosen the capscrews securing the pump casing to the motor assembly. Measure the clearance be tween the impeller and wear ring. If the clearance is too narrow, turn the adjusting screws in an alternat ing pattern to push the pump casing and suction head away from the impeller until the proper clear ance is achieved. If the clearance is too wide, use the previously removed hardware to draw the pump casing and suction head toward the impeller until the proper clearance is achieved.
When the face clearance is properly set, secure the adjusting screws by tightening the jam nuts against the back of the seal plate.
Final Assembly
If the pump is designed for guide a rail application and guide shoe was removed for disassembly, install a new guide shoe seal and secure the seal and guide shoe to the pump casing with the pre viously removed hardware.
If the pump is designed for a stand application, se cure the pump to the stand with the previously re move hardware.
Use a suitable lifting device to reposition the pump in the wet well or sump.
LUBRICATION
Seal Cavity
Before installing or removing the lubrica tion plugs, always make sure the pump is completely cool, and clean the area around the plugs to prevent contamination of the oil.
Check the oil level in the seal cavity before initial startup, after the first two weeks of operation, and every month thereafter.
Check the oil level only when the pump is cool. If the oil level plug is removed when the pump is hot, pressure in the seal cavity can cause hot oil to be ejected as the plug is removed.
Remove the lubrication plugs as indicated in Draining Oil. Position the pump upright and add premium quality submersible pump oil through one of the plug holes until the oil reaches the bot tom of the plug hole. Clean and re‐install the plugs.
The grade of lubricant used is critical to the opera tion of this pump. Use premium quality hydraulic oil as specified in Table E-2.
