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 pump is an Ultra V Series, semi-open impeller, self-priming centrifugal model with a suction check valve. The pump also is designed with external shimless adjusters for setting the wear plate to impeller clearance. The pump is close coupled to a John Deere 4024T diesel engine, and is designed for handling dirty water containing specified entrained solids and slurries. The basic material of construction is gray iron, with ductile iron impeller and steel wearing parts.

Because pump installations are seldom identical, this manual cannot possibly provide detailed instructions and precautions for every aspect of each specific application. Therefore, it is the responsibility of the owner/installer of the pump to ensure that applications not addressed in this manual are performed only after establishing that 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.

The following are used to alert maintenance personnel to procedures which require special attention, to those which could damage equipment, and to those which could be dangerous to personnel:

Immediate hazards which WILL result in severe personal injury or death. These instructions describe the procedure required and the injury which will result from failure to follow the procedure.

Hazards or unsafe practices which COULD result in severe personal injury or death. These instructions describe the procedure required and the injury which could result from failure to follow the procedure.

For information or technical assistance on the engine, contact the engine manufacturer’s local dealer or representative.

If there are any questions regarding the pump or its application which are not covered in this manual or in other literature accompanying this unit, please contact your Gorman-Rupp distributor, or write:

SAFETY - SECTION A

This information applies to Ultra V Se-

engine driven pumps. Refer to the

ries 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. Therefore, it is the owner/installer’s responsibility to ensure that applications not addressed in this manual are performed only after establishing that neither operator safety nor pump integrity are compromised by the installation.

Before attempting to open or service the pump:

1. Familiarize yourself with this manual.

2. Switch off the engine ignition and disconnect the positive battery cable 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.

during automatic operation. Disconnect the positive battery cable before performing any maintenance. Failure to do so may result in serious personal injury.

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.

Use lifting and moving equipment in good repair and with adequate capacity to prevent injuries to personnel or damage to equipment. The bail is intended for use in lifting the pump assembly only. Suction and discharge hoses and piping must be removed from the pump before lifting.

After the unit has been installed, make certain that the pump and all piping or hose connections are tight, properly supported and secure before operation.

This pump is equipped with an automatic starting system, and is subject to automatic restart. Keep hands and clothing away from the unit to prevent injury

Do not operate the pump against a closed discharge valve for long periods of time. If operated against a closed discharge valve, pump components will deteriorate, and the liquid could come to a boil, build pressure, and cause the pump casing to rupture or explode.

Do not remove plates, covers, gauges, pipe plugs, or fittings from an overheated pump. Vapor pressure within the pump can cause parts being disengaged to be ejected with great force. Allow the pump to completely cool before servicing.

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.

free of leaks. Never refuel a hot or running engine. Avoid overfilling the fuel tank. Always use the correct type of fuel.

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 2400 RPM.

Pumps and related equipment must be installed and operated according to all national, local and industry standards.

Fuel used by internal combustion engines presents an extreme explosion and fire hazard. Make certain that all fuel lines are securely connected and

Do not attempt to disengage any part of an overheated pump unit. Vapor pressure within the pump casing can eject these parts with great force when they are disengaged. Allow the pump to completely cool before servicing it.

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.

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.

If installed in a flooded suction application where the liquid is supplied to the pump under pressure, some of the information such as mounting, line configuration, and priming must be tailored to the

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.

For further assistance, contact your Gorman-Rupp distributor or the Gorman-Rupp Company.

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 assembly for cracks, dents,

damaged threads, and other obvious damage.

b. Check for and tighten loose attaching hard-

ware. Since gaskets tend to shrink after drying, check for loose hardware at mating surfaces.

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 perform duties as instructed.

compatible with the liquid being pumped. If hose is used in suction lines, it must be the rigid-wall, reinforced type to prevent collapse under suction. Using piping couplings in suction lines is not recommended.

Mounting

Locate the pump in an accessible place as close as practical to the liquid being pumped. Level mounting is essential for proper operation.

The pump may have to be supported or shimmed to provide for level operation or to eliminate vibration.

If the pump has been mounted on a moveable base, make certain the base is stationary by setting 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.

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. Never pull a pipe line into place by tightening the flange bolts and/or couplings.

Lines near the pump must be independently supported to avoid strain on the pump which could cause excessive vibration, decreased bearing life, and increased shaft and seal wear. If hose-type lines are used, they should have adequate support to secure them when filled with liquid and under pressure.

Gauges

Clearance

When positioning the pump, allow a minimum clearance of 18 inches (457,2 mm) in front of the back cover to permit removal of the cover and easy access to the pump interior.

SUCTION AND DISCHARGE PIPING

Pump performance is adversely effected by increased suction lift, discharge elevation, and friction losses. See the performance curve and notes on Page E-1 to be sure your overall application allows pump to operate within the safe operation range.

Most pumps are drilled and tapped for installing discharge pressure and vacuum suction gauges. If these gauges are desired for pumps that are not tapped, drill and tap the suction and discharge lines not less than 18 inches (457,2 mm) from the suction and discharge ports and install the lines. Installation closer to the pump may result in erratic readings.

SUCTION LINES

To avoid air pockets which could affect pump priming, the suction line must be as short and direct as possible. When operation involves a suction lift, the line must always slope upward to the pump from the source of the liquid being pumped; if the line

PAGE B − 3INSTALLATION

Page 11

OM−06266 ULTRA V SERIES

slopes down to the pump at any point along the suction run, air pockets will be created.

Fittings

Suction lines should be the same size as the pump inlet. If reducers are used in suction lines, they should be the eccentric type, and should be installed with the flat part of the reducers uppermost to avoid creating air pockets. Valves are not normally used in suction lines, but if a valve is used, install it with the stem horizontal to avoid air pockets.

Strainers

If a strainer is furnished with the pump, be certain to use it; any spherical solids which pass through a strainer furnished with the pump will also pass through the pump itself.

If a strainer is not furnished with the pump, but is installed by the pump user, make certain that the total area of the openings in the strainer is at least three or four times the cross section of the suction line, and that the openings will not permit passage of solids larger than the solids handling capability of the pump.

Suction Lines In Sumps

If a single suction line is installed in a sump, it should be positioned away from the wall of the sump at a distance equal to 1 1/2 times the diameter of the suction line.

If there is a liquid flow from an open pipe into the sump, the flow should be kept away from the suction inlet because the inflow will carry air down into the sump, and air entering the suction line will reduce pump efficiency.

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.

If two suction lines are installed in a single sump, the flow paths may interact, reducing the efficiency of one or both pumps. To avoid this, position the suction inlets so that they are separated by a distance equal to at least 3 times the diameter of the suction pipe.

Suction Line Positioning

This pump is designed to handle up to 2 1/2-inch (63,5 mm) diameter spherical solids.

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.

The depth of submergence of the suction line is critical to efficient pump operation. recommended minimum submergence vs. veloc-

ity.

Figure 2 shows

NOTE

The pipe submergence required may be reduced by installing a standard pipe increaser fitting at the end of the suction line. The larger opening size will reduce the inlet velocity. Calculate the required submergence using the following formula based on the increased opening size (area or diameter).

FLOAT SWITCHES

Installation

The standard pump is equipped with an auto-start control system, and can be conformed to start and stop as the liquid level in the wet well or sump rises and falls. The autostart unit employs either a single or double float switch system, where a bulb raises or lowers (floats) with the liquid level, thus activating an enclosed miniature switch. The floats are equipped with a socket type connector that plugs into a matching receptacle on the auto-start control box.

Standard floats are equipped with 50 feet (15,2 m) of cable.

When installing the floats, note the following:

a. Be sure to provide sufficient room in the wet

well or sump so that floats do not get obstructed or drawn into the suction line. If a flexible suction hose is used, it may be extended to lay along the bottom of the wet well or sump and the float can be attached to the hose

above the point where it bends along the bottom. Direct the suction line toward the flow, and the float(s) away from the flow. If a standpipe is available, attach the float switch cable to the standpipe in the sump at the approximate desired liquid level.

b. In a single float system, the cable can be teth-

ered to the suction line or standpipe approximately 6 inches (152 mm) above 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 extending the float end of the cable. The liquid level in the sump will increase approximately 8 inches (203 mm) between start/stop intervals for every 6 inches (152 mm) of cable increase.

c. If a double float switch system is used, posi-

tion the Start" float at the desired high water level in the sump, and the Stop" float at the desired low water level in the pump.

d. Refer to Figure 3 for additional float switch

data.

OPTIONAL SUBMERSIBLE TRANSDUCER

This unit may be equipped with an optional Electronic Pressure Switch (EPS) that works in conjunction with a submersible transducer. The submersible transducer converts pressure to an electrical signal proportional to liquid level. This electrical signal is distributed to the digital display on the EPS through a scaling circuit which converts the electrical signal to feet of water".

When installing the submersible transducer, note the following:

a. Handle the signal cable and transducer with

care during installation. Carefully lower the transducer into the wet well or sump; do not drop it to the bottom. To avoid clogging, suspend the transducer off the bottom.

b. Be sure to provide sufficient room in the wet

well or sump so that the transducer does not get drawn into the suction line. To prevent this, a flexible suction hose may be extended to lay along the bottom of the wet well or sump. The transducer can then be attached to the hose

e. Thoroughly clean the transducer after each

use to prevent clogging.

Do not disassemble the transducer or loosen the compression nut at the signal cable entry. This will void warranty. There are no user-serviceable parts inside. Do not nick or cut the jacket of the signal cable; this will cause leakage and void

warranty.

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.

Valves

If a throttling valve is desired in the discharge line, use a valve as large as the largest pipe to minimize friction losses. Never install a throttling valve in a suction line.

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.

FLOW

If the application involves a high discharge head, gradually close the discharge throttling valve before stopping the pump.

Bypass Lines

Self-priming pumps are not air compressors. During the priming cycle, air from the suction line must be vented to atmosphere on the discharge side. If the discharge line is open, this air will be vented through the discharge. However, if a check valve has been installed in the discharge line, the discharge side of the pump must be opened to atmospheric pressure through a bypass line installed between the pump discharge and the check valve. A self-priming centrifugal pump will not prime if there is sufficient static liquid head to hold the discharge check valve closed.

PAGE B − 7INSTALLATION

Page 15

OM−06266 ULTRA V SERIES

NOTE

The bypass line should be sized so that it does not affect pump discharge capacity; however, the bypass line should be at least 1 inch (25,4 mm) in diameter to minimize the chance of plugging.

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. In some installations, this bypass outline may be terminated with a six-to-eight foot (1,8 to 2,4 m) length of 1-1/4 inch (31,8 mm) I.D. smooth-bore hose; air and liquid vented during the priming process will then agitate the hose and break up any solids, grease, or other substances likely to cause clogging.

A bypass line that is returned to a wet well must be secured against being drawn into the pump suction inlet.

It is also recommended that pipe unions be installed at each 90 elbow in a bypass line to ease disassembly and maintenance.

In high discharge head applications (more than 30 feet (9,1 m), an excessive amount of liquid may be bypassed and forced back to the wet well under the full working pressure of the pump; this will reduce overall pumping efficiency. Therefore, it is

recommended that a Gorman-Rupp Automatic Air Release Valve be installed in the bypass line.

matic air release valve in a below-ground lift station), if a manual shut-off valve is installed anywhere in a bypass line, it must be a full-opening, ball-type valve to pre- vent plugging by solids.

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.

Allow an over-heated pump to completely cool before servicing. Do not remove plates, covers, gauges, or fittings from an over-heated pump. Liquid within the pump can reach boiling temperatures, and vapor pressure within the pump can cause parts being disengaged to be ejected with great force. After the pump completely cools, drain the liquid from the pump by removing the casing drain plug. Use caution when removing the plug to prevent injury to personnel from hot liquid.

AUTOMATIC AIR RELEASE VALVE

Gorman-Rupp Automatic Air Release Valves are reliable, and require minimum maintenance. See Automatic Air Release Valves in this section for installation and theory of operation of the Automatic Air Release Valve. Consult your GormanRupp distributor, or contact the Gorman-Rupp Company for selection of an Automatic Air Release Valve to fit your application.

When properly installed, a Gorman-Rupp Automatic Air Release Valve will permit air to escape through the bypass line and then close automatically when the pump is fully primed and pumping at full capacity.

Some leakage (1 to 5 gallons [3.8 to 19 liters] per minute) will occur when the valve is fully closed. Be sure the bypass

For multiple pump installations, it is recommended that each Air Release Valve be fitted with an independent bleeder line directed back to the wet well. If multiple Air Release Valves are installed in a system, do not direct bleeder lines to a common mani-

fold pipe. Contact your Gorman-Rupp distributor or the Gorman-Rupp Company for information about installation of an Automatic Air Release Valve for your specific application.

Zero offset and span adjustments are only necessary to calibrate a new unit, or when replacing the transducer. Once calibrated, ON" and OFF" setpoints will be stored in the unit’s memory. Liquid level adjustments will be used whenever ON" and OFF" liquid levels must be reset.

There are two reasons for the user to calibrate the unit. When power is applied, the unit confirms setpoints and other calibration information for validity. If the setpoints are not valid, the LCD screen shows EEP bAd" and the unit must be recalibrated. Also, if the unit is moved, or some other external change takes place, the unit must be recalibrated.

OPERATION

A Gorman-Rupp automatic air release valve may be installed in a bypass line, or the bypass line may be left open.

Lines With a Bypass

If a Gorman-Rupp Automatic Air Release Valve has been installed, the valve will automatically open to allow the pump to prime, and automatically close after priming is complete (see INSTALLATION for Air Release Valve operation).

If the bypass line is open, air from the suction line will be discharged through the bypass line back to the wet well during the priming cycle. 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. Priming is indicated by a positive reading on the discharge pressure gauge or by a quieter operation. The pump may not prime immediately because the suction line must first fill with liquid. If the pump fails to prime within five minutes, stop it and check the suction line for leaks.

After the pump has been primed, partially close the discharge line throttling valve in order to fill the line slowly and guard against excessive shock pressure which could damage pipe ends, gaskets, sprinkler heads, and any other fixtures connected to the line. When the discharge line is completely

filled, adjust the throttling valve to the required flow rate.

Leakage

No leakage should be visible at pump mating surfaces, or at pump connections or fittings. Keep all line connections and fittings tight to maintain maximum pump efficiency.

Liquid Temperature And Overheating

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. Operating against closed valves could bring the liquid to a boil, build pressure, and cause the pump to rupture or explode. If overheating occurs, stop the pump and allow it to cool before servicing it. Refill

the pump casing with cool liquid.

Allow an over-heated pump to completely cool before servicing. Do not re- move plates, covers, gauges, or fittings from an over-heated pump. Liquid within the pump can reach boiling temperatures, and vapor pressure within the pump can cause parts being disengaged to be ejected with great force. After the pump completely cools, drain the liquid from the pump by removing the casing drain plug. Use caution when removing the plug to prevent injury to personnel from hot liquid.

As a safeguard against rupture or explosion due to heat, this pump is equipped with a pressure relief valve which will open if vapor pressure within the pump casing reaches a critical point. If over-heating does occur, stop the pump immediately and allow it to cool before servicing it. Approach any over-heated pump cautiously. It is recommended that the pressure relief valve assembly be replaced at each overhaul, or any time the pump casing over-heats and activates the valve. Never

OPERATION PAGE C − 5

Page 22

OM−06266 ULTRA V SERIES

replace this valve with a substitute which has not been specified or provided by the Gorman-Rupp Company.

Strainer Check

If a suction strainer has been shipped with the pump or installed by the user, check the strainer regularly, and clean it as necessary. The strainer should also be checked if pump flow rate begins to drop. If a vacuum suction gauge has been installed, monitor and record the readings regularly to detect strainer blockage.

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 necessary, liquid pressure must be limited to 50% of the maximum permissible operating pressure shown on the pump performance curve.

In the manual mode, reduce the throttle speed slowly, and allow the engine to idle briefly before switching the HAND-OFF-AUTO switch to ‘OFF’.

If the application involves a high discharge head, gradually close the discharge throttling valve before stopping the pump.

After stopping the pump, switch off the engine ignition and remove the key to ensure that the pump will remain inoperative.

Automatic Stopping

In the automatic mode, the pump will stop when the liquid in the wet well or sump lowers and activates the Off" float switch(s). The pump will restart automatically when the liquid rises and activates the On" float switch(s).

Pump Vacuum Check

With the pump inoperative, install a vacuum gauge in the system, using pipe dope on the threads. Block the suction line and start the pump. At operating speed the pump should pull a vacuum of 20 inches (508 mm) or more of mercury. If it does not, check for air leaks in the seal, gasket, or discharge valve.

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

Safety Shutdown System

The unit is equipped with a safety system to automatically shut down the engine under certain conditions. The engine will automatically shut down:

1. If the engine exceeds its safe operating temperature.

2. If the engine oil pressure drops below design limits.

3. If the engine fails to start within a pre-set period of time.

4. If the engine speed exceeds the safe operating range.

5. If the engine fan belt breaks.

Lights on the control panel will indicate which of the safety features has caused the engine to shut down.

Manual Stopping

Never halt the flow of liquid suddenly. If the liquid being pumped is stopped abruptly, damaging shock waves can be transmitted to the pump and piping system. Close all connecting valves slowly.

Should any of the safety features cause the engine to shut down, the cause must be determined and corrected before putting the unit back into service. The engine will not restart until the keyswitch has been returned to the ‘OFF’ position for at least 10 seconds.

Never disconnect any of the safety shutdown features; this will void the warranty and could result in serious damage to the unit and/or injury to personnel. Safety shutdown features are pre-set at the factory; do not attempt to adjust any of the settings. Determine the cause of shutdown before putting the unit back into service. Consult the factory for additional information.

OPERATION IN EXTREME HEAT

The safety shutdown system will automatically stop the unit if engine operating temperature exceeds design limits. If engine over-temperature shutdown occurs, allow the unit to cool before restarting.

If engine overheating continues, check the engine lubricant level and viscosity. Consult the engine operation manual for the recommended lubricant for operation in extreme heat.

If the unit is equipped with the optional auto-start control, the float(s) may need to be adjusted to allow shorter run and longer cooling periods, if possible.

forming any maintenance. Failure to do so may result in serious personal injury.

Cold Weather Preservation

In below freezing conditions, drain the pump to prevent damage from freezing. Also, clean out any solids by flushing with a hose. Operate the pump for approximately one minute; this will remove any remaining liquid that could freeze the pump rotating parts. If the pump will be idle for more than a few hours, or if it has been pumping liquids containing a large amount of solids, drain the pump, and flush it thoroughly with clean water. To prevent large solids from clogging the drain port and preventing the pump from completely draining, insert a rod or stiff wire in the drain port, and agitate the liquid during the draining process. Clean out any remaining solids by flushing with a hose.

BEARING TEMPERATURE CHECK

Bearings normally run at higher than ambient temperatures because of heat generated by friction. Temperatures up to 160F (71C) are considered normal for bearings, and they can operate safely to at least 180F (82C).

Checking bearing temperatures by hand is inaccurate. Bearing temperatures can be measured accurately by placing a contact-type thermometer against the housing. Record this temperature for future reference.

A sudden increase in bearing temperatures is a warning that the bearings are at the point of failing to operate properly. Make certain that the bearing lubricant is of the proper viscosity and at the correct level (see LUBRICATION in Section E). Bearing overheating can also be caused by shaft misalignment and/or excessive vibration.

When pumps are first started, the bearings may seem to run at temperatures above normal. Continued operation should bring the temperatures down to normal levels.

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. For specific questions concerning your application, contact your GormanRupp distributor or the Gorman-Rupp Company.

Record keeping is an essential component of a good preventive maintenance program. Changes in suction and discharge gauge readings (if so

equipped) between regularly scheduled inspections can indicate problems that can be corrected before system damage or catastrophic failure occurs. The appearance of wearing parts should also be documented at each inspection for comparison as well. Also, if records indicate that a certain part (such as the seal) fails at approximately the same duty cycle, the part can be checked and replaced before failure occurs, reducing unscheduled down time.

For new applications, a first inspection of wearing parts at 250 hours will give insight into the wear rate for your particular application. Subsequent inspections should be performed at the intervals shown on the chart below. Critical applications should be inspected more frequently.

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 through 6) and the accompanying parts lists.

This manual will alert personnel to known procedures 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 personnel to ensure that only safe, established main- tenance procedures are used, and that any procedures not addressed in this manual are performed only after establishing that neither personal safety nor pump integrity are compromised by such practices.

OM−06266

Before attempting to open or service the pump:

1. Familiarize yourself with this manual.

2. Switch off the engine ignition and disconnect the positive battery cable 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.

Use lifting and moving equipment in good repair and with adequate capacity to prevent injuries to personnel or damage to equipment.

Suction Check Valve Removal

(Figure 4)

Many service functions may be performed by draining the pump and removing the back cover assembly. If major repair is required, the piping and/or power source must be disconnected. The following instructions assume complete disassembly is required.

Before attempting to service the pump, disconnect or lock out the power source and take precautions to ensure that it will remain inoperative. Close all valves in the suction and discharge lines.

For engine disassembly and repair, consult the literature supplied with the engine, or contact your local engine representative.

MAINTENANCE & REPAIR PAGE E − 13

If the check valve assembly (26) is to be serviced, disengage the hardware (28 and 29) and remove the check valve cover (27). Pull the check valve assembly from the slot in the pump casing (1).

Back Cover And Wear Plate Removal

(Figure 4)

The wear plate (7) is easily accessible and may be serviced by removing the back cover assembly (12). Before attempting to service the pump, remove the pump casing drain plug (6) and drain the pump. Clean and reinstall the drain plug.

Remove the back cover nuts (15) and pry the back cover and assembled wear plate from the pump casing (1).

Page 40

OM−06266 ULTRA V SERIES

NOTE

An alternate method of removing the back cover from the pump casing is to remove the back cover nuts (15) and two diagonally opposing locking collars (19). Install two 1/2−13 UNC x 2 inch long screws in the tapped holes in the back cover and use them to press the back cover out of the pump casing.

Inspect the wear plate, and replace it if badly scored or worn. To remove the wear plate, disengage the hardware (9 and 10).

Inspect the back cover O-rings (8 and 11) and replace it if damaged or worn.

Separating Intermediate And Drive Assembly From Engine

(Figure 6)

Further disassembly requires separating the pump end and drive assembly from the engine. Install a standard 5/8-11 UNC lifting eye in the tapped hole in the top of the pump casing. Be sure to screw the eye into the casing until fully engaged. Support the pump using a suitable hoist and the lifting eye.

two allen head setscrews from the bushing (1). Screw one of the setscrews into the puller hole on the circumference of the bushing. As the coupling and bushing separate, remove the bushing, and slide the coupling off the shaft. Remove the shaft key (23, Figure 5).

It is not necessary to remove the outer ring of the coupling from the engine flywheel unless the coupling must be replaced. To remove the ring, disengage the hardware (3 and 4) securing it to the flywheel.

Remove any leveling shims used under the casing mounting feet. Tie and tag the shims for ease of reassembly.

Move the pump end to a clean, well equipped shop area for further disassembly.

Loosening Impeller

(Figure 5)

Before attempting to loosen the impeller, remove the seal cavity drain plug (15A) and drain the lubricant. This will prevent the oil from escaping as the impeller is removed. Clean and reinstall the drain plug.

Do not attempt to lift the complete pump unit using the lifting eye. It is designed to facilitate removal or installation of individual components only. Additional weight may result in damage to the pump or failure of the eye bolt.

Remove the hardware securing the pump casing to the base.

Disengage the hardware (2 and 3, Figure 2) securing the drive flange to the engine bellhousing, and remove the guards (19, Figure 5). Separate the pump end and drive assembly from the engine by pulling the pump end straight away from the engine.

As the assemblies separate, the flexible portion of the coupling assembly (2) will remain on the shaft. To remove the coupling from the shaft, unscrew the

With the pump end separated from the engine and the back cover (12, Figure 4) removed, wedge a block of wood between the vanes of the impeller and the pump casing to prevent rotation.

If removed, install the shaft key (23) in the shaft keyway. Install a lathe dog on the drive end of the shaft (24) with the V" notch positioned over the shaft key.

With the impeller rotation still blocked, see Figure 7 and use a long piece of heavy bar stock to pry against the arm of the lathe dog in a counterclockwise direction (when facing the drive end of the shaft). Use caution not to damage the shaft or keyway. When the impeller breaks loose, remove the lathe dog, key and wood block.

NOTE

Do not remove the impeller until the rotating assembly has been removed from the pump casing.

NOTE

An optional disassembly tool is available from the

factory. If the tool is used, follow the instructions

packed with it. A similar tool may be assembled us-

ing 1/2-inch pipe (schedule 80 steel or malleable

iron) and a standard tee (see Figure 8). All threads

are 1/2-inch NPT. Do not pre-assemble the tool.

With the rotating assembly removed from the pump casing, unscrew the impeller from the shaft. Use caution when unscrewing the impeller; tension on the shaft seal spring will be released as the impeller is removed. Inspect the impeller and replace if cracked or badly worn.

Remove the impeller adjusting shims (2); tie and tag the shims, or measure and record their thickness for ease of reassembly.

Seal Removal

(Figure 5)

Slide the integral shaft sleeve and rotating portion of the seal off the shaft as a unit.

Use a pair of stiff wires with hooked ends to remove the stationary element and seat.

MAINTENANCE & REPAIR PAGE E − 15

An alternate method of removing the stationary seal components is to remove the hardware (8 and

9) and separate the seal plate (4) and gasket (5) from the bearing housing (7). Position the seal plate on a flat surface with the impeller side down. Use a wooden dowel or other suitable tool to press on the back side of the stationary seat until the seat, O-rings, and stationary element can be removed.

To prevent damage during removal from the shaft, it is recommended that bearings be cleaned and inspected in place. It is strongly recommended that the bearings be replaced any time the shaft and bear- ings are removed.

Remove the shaft sleeve O-ring (25).

If no further disassembly is required, refer to Seal

Installation.

flammable. Use them only in a well ventilated area free from excessive heat, sparks, and flame. Read and follow all precautions printed on solvent containers.

Shaft and bearing disassembly in the field is not recommended. These operations should be performed only in a properlyequipped shop by qualified personnel.

Remove the bearing housing drain plug (15) anddrain the lubricant. Clean and reinstall the drain plug.

Disengage the hardware (16 and 17) and slide the drive flange (18) and oil seal (6B) off the shaft. Remove the flange gasket (20) and press the oil seal from the drive flange.

Place a block of wood against the impeller end of the shaft and tap the shaft and assembled bearings (22 and 26) from the bearing housing.

Pry or press the oil seals (6 and 6A) from the bearing housing.

After removing the shaft and bearings, clean and inspect the bearings in place as follows.

Clean the bearings thoroughly in fresh cleaning solvent. Dry the bearings with filtered compressed air and coat with light oil.

Bearings must be kept free of all dirt and foreign material. Failure to do so will greatly shorten bearing life. Do not spin dry bearings. This may scratch the balls or races and cause premature bearing failure.

Rotate the bearings by hand to check for roughness or binding and inspect the bearing balls. If rotation is rough or the bearing balls are discolored, replace the bearings.

The bearing tolerances provide a tight press fit onto the shaft and a snug slip fit into the bearing housing. Replace the bearings, shaft, or bearing housing if the proper bearing fit is not achieved.

If bearing replacement is required, remove the outboard bearing snap ring (21) and use a bearing puller to remove the bearings from the shaft.

Shaft and Bearing Reassembly and Installation

(Figure 5)

Clean the bearing housing, shaft and all component parts (except the bearings) with a soft cloth soaked in cleaning solvent. Inspect the parts for wear or damage as necessary.

Most cleaning solvents are toxic and flammable. Use them only in a well ventilated area free from excessive heat, sparks, and flame. Read and follow all precautions printed on solvent containers.

Inspect the shaft for distortion, nicks or scratches, or for thread damage on the impeller end. Dress small nicks and burrs with a fine file or emery cloth. Replace the shaft if defective.

Position the inboard oil seal (6A) in the bearing housing bore with the lip positioned as shown in Figure 5. Press the oil seal into the housing until the face is just flush with the machined surface on the inside of the housing.

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 thor- oughly 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.

After the bearings have been installed and allowed to cool, check to ensure that they have not moved away from the shaft shoulders in shrinking. If movement has occurred, use a suitably sized sleeve and a press to reposition the bearings against the shaft shoulders.

If heating the bearings is not practical, use a suitably sized sleeve, and an arbor (or hydraulic) press to install the bearings on the shaft.

When installing the bearings onto the shaft, never press or hit against the outer race, balls, or ball cage. Press only on the inner race.

To prevent damage during removal from the shaft, it is recommended that bearings

be cleaned and inspected in place. It is strongly recommended that the bearings be replaced any time the shaft and bear- ings are removed.

NOTE

Position the outboard bearing (22) on the shaft with the integral retaining ring on the bearing O.D. toward the drive end of the shaft.

The bearings may be heated to ease installation. An induction heater, hot oil bath, electric oven, or hot plate may be used to heat the bearings. Bearings should never be heated with a direct flame or directly on a hot plate.

MAINTENANCE & REPAIR PAGE E − 17

It is recommended that a sleeve be positioned against the inboard oil seal (6A) to prevent the lip of the oil seal from rolling as the shaft and bearings are installed in the bearing housing. The O.D. of the sleeve should be just smaller than the bearing housing bore, while the I.D. of the sleeve should be just larger than the O.D. of the lip seal area of the shaft.

With the lip seal sleeve in place, lubricate the lip seal area of the shaft, and slide the shaft and assembled bearings into the bearing housing until the retaining ring on the outboard bearing seats against the bearing housing. Remove the lip seal sleeve.

Seal Installation

(Figures 5, 9, 10 and 11)

When installing the shaft and bearings into the bearing bore, push against the outer race. Never hit the balls or ball cage.

Position the outboard oil seal (6) on the lubricated shaft with the lip positioned as shown in Figure 5. Press the oil seal into the bearing housing until the face of the seal is just flush with the machined surface on the bearing housing.

Press the oil seal (6B) into the drive flange (18) with the lip positioned as shown in Figure 5. Replace the flange gasket (20) and secure the flange to the bearing housing with the hardware (16 and 17). Be careful not to damage the oil seal lip on the shaft keyway.

Most cleaning solvents are toxic and flammable. Use them only in a well ventilated area free from excessive heat, sparks, and flame. Read and follow all precautions printed on solvent containers.

Clean the seal cavity and shaft with a cloth soaked in fresh cleaning solvent. Inspect the stationary seat bore in the seal plate for dirt, nicks and burrs, and remove any that exist. The stationary seat bore must be completely clean before installing the seal.

Lubricate the bearing housing as indicated in LU- BRICATION.

A new seal assembly should be installed any time the old seal is removed from the pump. Wear patterns on the finished faces cannot be realigned during reassembly. Reusing an old seal could result in premature failure.

To ease installation of the seal, lubricate the shaft sleeve O-ring (25) and the external stationary seat O-ring with a very small amount of light lubricating oil. See Figure 9 for seal part identification.

If the seal plate (4) was removed, install the seal plate O-ring (27) and lubricate it with light grease. Install the seal plate gasket (5). Position the seal plate over the shaft and secure it to the bearing housing with the hardware (8 and 9). Install the bearing housing O-ring (28) and lubricate it with light grease.

To prevent damaging the shaft sleeve O-ring (25) on the shaft threads, stretch the O-ring over a piece of tubing that the I.D. is a little larger than the O.D. of the shaft. Slide the tube over the shaft threads, then slide the O-ring off the tube and onto the shaft. Remove the tube, and continue to slide the O-ring

down the shaft until it seats against the shaft shoulder.

When installing a new cartridge seal assembly, remove the seal from the container, and remove the mylar storage tabs, if so equipped, from between the seal faces.

New cartridge seal assemblies may be equipped with mylar storage tabs between the seal faces. If so equipped, these storage tabs must be removed before installing the seal.

Lubricate the external stationary seat O-ring with light oil. Slide the seal assembly onto the shaft until the external stationary seat O-ring engages the bore in the seal plate.

Handle the seal parts with extreme care to prevent damage. Be careful not to contaminate precision 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.

As the stationary seat becomes fully seated, the seal spring compresses, and the shaft sleeve will break the nylon shear ring. This allows the sleeve to slide down the shaft until seated against the shaft shoulder. Continue to screw the impeller onto the shaft until the impeller, shims, and sleeve are fully seated against the shaft shoulder (see Figure

Do not attempt to separate the rotating portion of the seal from the shaft sleeve when reusing an old seal. The rubber bellows will adhere to the sleeve during use, and attempting to separate them could damage the bellows.

Inspect the seal components for wear, scoring, grooves, and other damage that might cause leakage. Inspect the integral shaft sleeve for nicks or cuts on either end. If any components are worn, or the sleeve is damaged, replace the complete seal; never mix old and new seal parts.

Install the stationary seal element in the stationary seat. Press this stationary subassembly into the seal plate bore until it seats squarely against the bore shoulder. A push tube made from a piece of plastic pipe would aid this installation. The I.D. of

Impeller Installation

(Figure 5)

Inspect the impeller, and replace it if cracked or badly worn. Inspect the impeller and shaft threads for dirt or damage, and clean or dress the threads as required.

The shaft and impeller threads must be completely clean before reinstalling the impeller. Even the slightest amount of dirt on the threads can cause the impeller to seize to the shaft, making future removal difficult or impossible without damage to the impeller or shaft.

Install the same thickness of impeller adjusting shims (2) as previously removed. Apply ‘NeverSeez’ or equivalent to the shaft threads and screw the impeller onto the shaft until tight. Be sure the seal spring seats squarely on the back side of the impeller.

reaching through the priming port with a feeler gauge.

Rotating Assembly Installation

(Figure 4)

NOTE

If the pump has been completely disassembled, it is recommended that the suction check valve and back cover assembly be reinstalled at this point. The back cover assembly must be in place to adjust the impeller face clearance.

Install the seal plate and bearing housing O-rings (8A and 11A) and lubricate them with light grease. Ease the rotating assembly into the pump casing using the installation tool. Be careful not to damage the O-ring.

Install the rotating assembly spacers (40). Secure the rotating assembly to the pump casing with the hardware (13 and 38).

To set the impeller and wear plate clearance refer to the Back Cover Installation And Adjustment.

Back Cover Installation And Adjustment

(Figures 4 and 12)

If the wear plate (7) was removed for replacement, carefully center it on the back cover and secure it with the hardware (9 and 10). The wear plate must be concentric to prevent binding when the back cover is installed.

NOTE

At the slightest sign of binding, immediately back the impeller off, and check the threads for dirt. Do

not try to force the impeller onto the shaft.

A clearance of .025 to .040 inch (0,64 to 1,02 mm) between the impeller and the seal plate is recommended for maximum pump efficiency. Measure this clearance, and add or remove impeller adjusting shims as required.

NOTE

If the rotating assembly has been installed in the pump casing, this clearance may be measured by

MAINTENANCE & REPAIR PAGE E − 21

The clearance between the impeller and wear plate is adjusted using four adjusting screws (18) and locking collars (19). There are 18 detents on the I.D. of each locking collar. Indexing the collars one detent on the adjusting screws represents approximately .005 inch (0,13 mm) of wear plate clearance. The recommended clearance between the wear plate and the impeller is .010 to .020 inch (0,25 to 0,50 mm).

Replace the back cover O-rings (8 and 11) and lubricate them with a generous amount of No. 2 grease. Clean any scale or debris from the contacting surfaces in the pump casing that might interfere or prevent a good seal with the back cover.

Figure 12. Installing and Adjusting Back Cover

Screw the four adjusting screws (18) into the tapped holes in the back cover plate until they are just flush with the machined surface on the back side of the cover plate.

Remove the first two back cover nuts from their studs. Turn the adjusting screws clockwise until they engage the pump casing. Install the locking collars and hardware (13 and 14). Reinstall the back cover nuts.

Be sure the wear plate does not scrape against the impeller.

Over time it may be necessary to repeat the adjustment process to compensate for normal wear between the impeller and wear plate. When all of the adjustment has been used on the back cover side of the pump, an additional 0.125 inch (3,2 mm) of adjustment may be obtained by removing the rotating spacers (40).

Allow an installed pump to completely cool before draining liquid from the pump casing. Remove the back cover. Remove the rotating assembly adjusting shims, then reinstall the hardware securing the rotating assembly to the pump casing. Perform the back cover adjustment procedure described above to obtain the proper face clearance.

Align the back cover plate over the studs (5) and slide it into the pump casing. Use two back cover nuts (15) on diagonally opposing studs to press the back cover into the pump casing until the wear plate just touches the impeller when the shaft is turned by hand. Tighten the back cover nuts

evenly to avoid binding.

With the wear plate just touching the impeller, turn the two free adjusting screws until they engage the pump casing. Position the locking collars over the adjusting screws so the holes in the collars for the locking screws align approximately with the holes in the cover plate.

Loosen the back cover nuts used to press the back cover into the pump casing one full turn.

Pull the collars off the adjusting screws, index them three detents counterclockwise, and reinstall the collars on the adjusting screws. Use the collars to turn the adjusting screws clockwise until the holes in the locking collars realign with the tapped screw holes in the back cover plate. Secure the locking collars to the back cover plate with the hardware (13 and 14). Install the two remaining back cover nuts snugly against the adjusting screws.

Suction Check Valve Installation

(Figure 4)

Inspect the check valve assembly (26) and replace it if badly worn.

Position the check valve in the mounting slot in the pump casing (1) with the G-R" logo facing away from the inside of the pump casing. Position the check valve cover (27) over the check valve slot and secure with the hardware (28 and 29).

NOTE

If the suction or discharge flanges were removed, replace the respective gaskets, apply ‘Permatex Aviation No. 3 Form-A-Gasket’ or equivalent compound to the mating surfaces, and secure them to the pump casing with the attaching hardware.

Securing Pump End To Engine

(Figure 6)

Install the shaft key (23, Figure 5) in the shaft keyway. Position the flexible portion of the coupling assembly (2) on the shaft as shown in Figure 6.

MAINTENANCE & REPAIRPAGE E − 22

Page 49

ULTRA V SERIES

OM−06266

Align the keyway in the bushing (1) with the shaft key, and slide it onto the shaft until it is just flush with the end of the shaft. Rotate the flexible portion of the coupling until the tapped holes for the two setscrews align with those in the bushing, and install the setscrews.

Make certain that the flexible portion of the coupling is mounted as shown in Figure 6. This is critical. If the coupling is not properly positioned on the shaft, the coupling parts may not fully engage, or a pre-load condition can cause premature bearing failure.

The end of the shaft must be recessed 0.31 inch (7,9 mm) from the face of the bushing. This will allow the two portions of the coupling to fully engage when the drive flange is secured to the engine bellhousing, without pre-loading the bearings.

With the flexible portion of the coupling and the bushing properly positioned on the shaft, tighten the two setscrews in an alternating sequence until the bushing and coupling are fully secured. Torque the setscrews to 14.6 ft. lbs. (175 in. lbs. or 2 m. kg.).

If the complete coupling assembly is being replaced, apply ‘Loctite Retaining Compound No. 242’ or equivalent to the threads of the capscrews (3 and 4), and secure the outer ring of the coupling to the engine flywheel by torquing the hardware to 45 ft. lbs. (540 in. lbs. or 6,2 m. kg.).

Install the intermediate guards (19, Figure 5), and secure the drive flange to the engine bellhousing with the hardware (2 and 3, Figure 2).

(Figure 1)

Install any leveling shims used under the casing mounting feet, and secure the casing to the base with the previously removed hardware.

If a lifting eye was used to move the pump casing, be sure to remove the lifting eye from the pump casing.

PRESSURE RELIEF VALVE MAINTENANCE

(Figure 4)

The back cover is equipped with a pressure relief valve to provide additional safety for the pump and operator (refer to Liquid Temperature And Over- heating in OPERATION).

It is recommended that the pressure relief valve assembly be replaced at each overhaul, or any time the pump overheats and activates the valve. Never replace this valve with a substitute which has not been specified or provided by the Gorman-Rupp Company.

Using a suitable lifting device, position the pump end so the flexible portion of the coupling seats inside the outer ring attached to the engine flywheel.

NOTE

To ease installation, lightly lubricate the rubber portion of the coupling with a non-petroleum based lubricant such as vegetable oil or glycerin, or a silicon-based lubricant such as WD40" or equivalent. Do not use petroleum-based lubricants, or any other substance which may soften or otherwise damage the rubber.

MAINTENANCE & REPAIR PAGE E − 23

Periodically, the valve should be removed for inspection and cleaning. When reinstalling the relief valve, apply ‘Loctite Pipe Sealant With Teflon No. 592’, or equivalent compound, on the relief valve threads. Position the valve as shown in Figure 4 with the discharge port pointing down.

Final Pump Assembly

(Figure 1)

Be sure the pump is secured to the base and en-

gine. Be sure to install any guards used over the rotating members.

Page 50

OM−06266 ULTRA V SERIES

Bearings

(Figure 5)

Do not operate the pump without the guards in place over the rotating parts. Exposed rotating parts can catch clothing, fingers, or tools, causing severe injury to personnel.

Install the suction and discharge lines and open all valves. Make certain that all piping connections are tight, properly supported and secure.

Be sure the pump and engine have been properly lubricated, see LUBRICATION.

Remove the fill cover assembly (31, Figure 4) and fill the pump casing with clean liquid. Reinstall the fill cover and tighten it. Refer to OPERATION, Section C, before putting the pump back into service.

LUBRICATION

The bearing housing was fully lubricated when shipped from the factory. Check the oil level regularly through the sight gauge (14A) at the middle of the gauge. When lubrication is required, add SAE No. 30 non-detergent oil through the hole for the air vent (12). Do not over-lubricate. Over-lubrication can cause the bearings to overheat, resulting in premature bearing failure.

and maintain it

NOTE

The white reflector in the sight gauge must be positioned horizontally to provide proper drainage.

Under normal conditions, drain the bearing housing once each year and refill with approximately 11 ounces (0,3 liter) clean oil. Change the oil more frequently if the pump is operated continuously or installed in an environment with rapid temperature change.

Seal Assembly

(Figure 5)

Before starting the pump, remove the vented plug (10) and fill the seal cavity with approximately 60 ounces (1,8 liters) of SAE No. 30 non-detergent oil to the middle of the sight gauge (14) and maintain it at the middle of the gauge. Clean and reinstall the vented plug. Maintain the oil at this level.

NOTE

The white reflector in the sight gauge must be positioned horizontally to provide proper drainage.

Monitor the condition of the bearing lubricant regularly for evidence of rust or moisture condensation. This is especially important in areas where variable hot and cold temperatures are common.

For cold weather operation, consult the factory or a lubricant supplier for the recommended grade of oil.
