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 a 10 Series, semi‐open impeller, self‐ priming centrifugal model with a suction check valve. The pump is designed to be close‐coupled to a Deutz diesel engine.

The pump is designed for handling dirty water con taining specified entrained solids. The basic mate rial of construction for wetted parts is gray iron, with ductile iron impeller and steel wearing parts.

Because pump installations are seldom identical, this manual cannot possibly provide detailed in structions and precautions for every aspect of each specific application. Therefore, it is the re sponsibility 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 com promised by the installation. Pumps and related equipment must be installed and operated ac cording to all national, local and industry stan dards.

For information or technical assistance on the en gine, contact the engine manufacturer's local dealer or representative.

The following are used to alert maintenance per sonnel to procedures which require special atten tion, 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 re quired 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.

SAFETY - SECTION A

This information applies to 10 Series Engine Driven pumps. Refer to the man ual accompanying the engine before at tempting to begin operation.

Because pump installations are seldom identical, this manual cannot possibly provide detailed instructions and pre cautions for each specific application. Therefore, it is the owner/installer's re sponsibility to ensure that applications not addressed in this manual are per formed only after establishing that nei ther operator safety nor pump integrity are compromised by the installation.

Before attempting to install, operate, or service this pump, familiarize yourself with this manual, and with all other liter ature shipped with the pump. Unfamil iarity with all aspects of pump operation covered in this manual could lead to de struction of equipment, injury, or death to personnel.

5. Close the suction and discharge valves.

6. Vent the pump slowly and cau tiously.

7. Drain the pump.

This pump is designed to handle dirty water containing specified entrained solids. Do not attempt to pump volatile, corrosive, or flammable materials, or any 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 dam age to equipment. Suction and dis charge hoses and piping must be re moved from the pump before lifting.

Before attempting to open or service the pump:

1. Familiarize yourself with this man ual.

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.

After the pump has been positioned, make certain that the pump and all pip ing or hose connections are tight, prop erly supported and secure before oper ation.

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

PAGE A - 1SAFETY

OM-01604

10 SERIES

Do not remove plates, covers, gauges, pipe plugs, or fittings from an over heated pump. Vapor pressure within the pump can cause parts being disen gaged to be ejected with great force. Al low the pump to completely cool before servicing.

Do not operate an internal combustion engine in an explosive atmosphere. When operating an internal combustion engine in an enclosed area, make sure exhaust fumes are piped to the outside. These fumes contain carbon monoxide, a deadly gas that is colorless, tasteless and odorless.

Fuel used by internal combustion en gines presents an extreme explosion and fire hazard. Make certain that all fuel lines are securely connected and free of leaks. Never refuel a hot or run ning 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 2200 RPM.

Allow an over‐heated pump to com pletely cool before servicing. Do not re move plates, covers, gauges, or fittings from an over‐heated pump. Liquid with in the pump can reach boiling tempera tures, and vapor pressure within the pump can cause parts being disen gaged to be ejected with great force. Af ter 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.

Pumps and related equipment must be in stalled and operated according to all na tional, local and industry standards.

PAGE A - 2 SAFETY

INSTALLATION - SECTION B

OM-0160410 SERIES

Review all SAFETY information in Section A.

Since pump installations are seldom identical, this section offers only general recommendations and practices required to inspect, position, and ar range the pump and piping.

Most of the information pertains to a standard

static lift application where the pump is posi tioned 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

OUTLINE DRAWING

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. (See Sec tion E, Page 1.)

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

Pump Dimensions

See Figure 1 for the approximate physical dimen sions of this pump.

Figure 1. Pump Model 16C20‐F4L

PAGE B - 1INSTALLATION

OM-01604 10 SERIES

PREINSTALLATION INSPECTION

The pump assembly was inspected and tested be fore shipment from the factory. Before installation, inspect the pump for damage which may have oc curred during shipment. Check as follows:

a. Inspect the pump for cracks, dents, damaged

threads, and other obvious damage.

b. Check for and tighten loose attaching hard

ware. Since gaskets tend to shrink after dry ing, check for loose hardware at mating sur faces.

c. Carefully read all warnings and cautions con

tained in this manual or affixed to the pump, and perform all duties indicated.

d. Check levels and lubricate as necessary. Re

fer to LUBRICATION in the MAINTENANCE AND REPAIR section of this manual and per form duties as instructed.

e. If the pump has been stored for more than 12

months, some of the components or lubri cants may have exceeded their maximum shelf life. These must be inspected or re placed to ensure maximum pump service.

If the maximum shelf life has been exceeded, or if anything appears to be abnormal, contact your Gorman‐Rupp distributor or the factory to deter mine the repair or updating policy. Do not put the pump into service until appropriate action has been taken.

Before installing the battery, clean the positive and negative cable connectors, and the battery termi nals. Secure the battery by tightening the holddown brackets. The terminals and clamps may be coated with petroleum jelly to retard corro sion. Connect and tighten the positive cable first, then the negative cable.

POSITIONING PUMP

Lifting

Pump unit weights will vary depending on the mounting and drive provided. Check the shipping tag on the unit packaging for the actual weight, and use lifting equipment with appropriate capacity. Drain the pump and remove all customer‐installed equipment such as suction and discharge hoses or piping before attempting to lift existing, installed units.

Battery Specifications And Installation

Unless otherwise specified on the pump order, the engine battery was not included with the unit. Re fer to the following specifications when selecting a battery.

The pump assembly can be seriously damaged if the cables or chains used to lift and move the unit are improperly wrapped around the pump.

Mounting

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

The pump may have to be supported or shimmed to provide for level operation or to eliminate vibra tion.

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

OM-0160410 SERIES

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 tion. 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_.

Clearance

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

off horizontal for continuous opera

SUCTION AND DISCHARGE PIPING

Pump performance is adversely effected by in creased suction lift, discharge elevation, and fric tion losses. Contact the factory to be sure your overall application allows the pump to operate within the safe operation range.

Materials

Lines near the pump must be independently sup ported 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

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

Either pipe or hose maybe used for suction and discharge lines; however, the materials must be compatible with the liquid being pumped. If hose is used in suction lines, it must be the rigid‐wall, rein forced type to prevent collapse under suction. Us ing piping couplings in suction lines is not recom mended.

Line Configuration

Keep suction and discharge lines as straight as possible to minimize friction losses. Make mini mum use of elbows and fittings, which substan tially increase friction loss. If elbows are necessary, use the long‐radius type to minimize friction loss.

Connections to Pump

Before tightening a connecting flange, align it ex actly with the pump port. Never pull a pipe line into place by tightening the flange bolts and/or cou plings.

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 in stalled with the flat part of the reducers uppermost to avoid creating air pockets. Valves are not nor mally used in suction lines, but if a valve is used, install it with the stem horizontal to avoid air pock ets.

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

PAGE B - 3INSTALLATION

OM-01604 10 SERIES

of solids larger than the solids handling capability of the pump.

This pump is designed to handle up to 3 inch (76,2 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 air tight seal. Follow the sealant manufacturer's rec ommendations when selecting and applying the pipe dope. The pipe dope should be compatible with the liquid being pumped.

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 diame ter 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 suc tion inlet because the inflow will carry air down into the sump, and air entering the suction line will re duce pump efficiency.

If it is necessary to position inflow close to the suc tion inlet, install a baffle between the inflow and the suction inlet at a distance 1 1/2 times the diameter of the suction pipe. The baffle will allow entrained air to escape from the liquid before it is drawn into the suction inlet.

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 dis tance equal to at least 3 times the diameter of the suction pipe.

Suction Line Positioning

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).

PAGE B - 4 INSTALLATION

OM-0160410 SERIES

Figure 2. Recommended Minimum Suction Line Submergence vs. Velocity

DISCHARGE LINES

Siphoning

Do not terminate the discharge line at a level lower than that of the liquid being pumped unless a si phon breaker is used in the line. Otherwise, a si phoning 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 in stalled in the discharge line to protect the pump from excessive shock pressure and reverse rota tion when it is stopped.

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

Bypass Lines

Self‐priming pumps are not air compressors. Dur ing 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 dis charge side of the pump must be opened to atmos pheric pressure through a bypass line installed be tween 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 dis charge check valve closed.

NOTE

The bypass line should be sized so that it does not affect pump discharge capacity; however, the by pass line should be at least 1 inch (25,4 mm) in di

PAGE B - 5INSTALLATION

OM-01604 10 SERIES

ameter 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 in stalled 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 re duce overall pumping efficiency. Therefore, it is

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

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 Auto matic Air Release Valve. Consult your Gorman‐ Rupp distributor, or contact the Gorman‐Rupp Company for selection of an Automatic Air Release Valve to fit your application.

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 dan gerous overheating and possible explo sive rupture of the pump casing. Per sonnel could be severely injured.

Allow an over‐heated pump to com pletely cool before servicing. Do not re move plates, covers, gauges, or fittings from an over‐heated pump. Liquid with in the pump can reach boiling tempera tures, and vapor pressure within the pump can cause parts being disen gaged to be ejected with great force. Af ter the pump completely cools, drain the liquid from the pump by removing the casing drain plug. Use caution when re moving the plug to prevent injury to per sonnel from hot liquid.

AUTOMATIC AIR RELEASE VALVE

When properly installed and correctly adjusted to the specific hydraulic operating conditions of the application, the Gorman‐Rupp Automatic Air Re lease Valve will permit air to escape through the by pass line, and then close automatically when the pump is fully primed and pumping at full capacity.

Theory of Operation

Except in certain specific applications (to prevent flooding during service of an auto matic air release valve in a below‐ground lift station), if a manual shut‐off valve is in stalled anywhere in a bypass line, it must

PAGE B - 6 INSTALLATION

Figure 4. Valve in Open Position

OM-0160410 SERIES

Figures 4 and 5 show a cross‐sectional view of the Automatic Air Release Valve, and a corresponding description of operation.

During the priming cycle, air from the pump casing flows through the bypass line, and passes through the Air Release Valve to the wet well (Figure 4).

Figure 5. Valve in Closed Position

When the pump is fully primed, pressure resulting from flow against the valve diaphragm com presses the spring and closes the valve (Figure 5). The valve will remain closed, reducing the bypass of liquid to 1 to 5 gallons (3,8 to 18,9 L) per minute, until the pump loses its prime or stops.

When the pump shuts down, the spring returns the diaphragm to its original position. Any solids that may have accumulated in the diaphragm chamber settle to the bottom and are flushed out during the next priming cycle.

NOTE

The valve will remain open if the pump does not reach its designed capacity or head. Valve closing pressure is dependent upon the discharge head of the pump at full capacity. The range of the valve closing pressure is established by the tension rate of the spring as ordered from the factory. Valve clos ing pressure can be further adjusted to the exact system requirements by moving the spring retain ing pin up or down the plunger rod to increase or decrease tension on the spring. Contact your Gor man‐Rupp distributor or the Gorman‐Rupp Compa ny for information about an Automatic Air Release Valve for your specific application.

Air Release Valve Installation

The Automatic Air Release Valve must be inde pendently mounted in a horizontal position and connected to the discharge line of the self‐priming centrifugal pump (see Figure 6).

Some leakage (1 to 5 gallons (3,8 to 18,9 Liters) per minute) will occur when the valve is fully closed. Be sure the bypass line is directed back to the wet well or tank to prevent hazardous spills.

NOTE

If the Air Release Valve is to be installed on a staged pump application, contact the factory for specific installation instructions.

The valve inlet line must be installed between the pump discharge port and the non‐pressurized side of the discharge check valve. The valve inlet is at the large end of the valve body, and is provided with standard 1 inch NPT pipe threads.

The valve outlet is located at the opposite end of the valve, and is also equipped with standard 1 inch NPT pipe threads. The outlet should be con nected to a bleed line which slopes back to the wet well or sump. The bleed line must be the same size as the inlet piping, or larger. If piping is used for the bleed line, avoid the use of elbows whenever pos sible.

NOTE

It is recommended that each Air Release Valve be

fitted with an independent bleeder line directed back to the wet well. However, if multiple Air Re lease Valves are installed in a system, the bleeder lines may be directed to a common manifold pipe. Contact your Gorman‐Rupp distributor or the Gor man‐Rupp Company for information about installa tion of an Automatic Air Release Valve for your spe cific application.

ALIGNMENT

The alignment of the pump and the engine is criti cal for trouble‐free mechanical operation. See Sec tion E, Securing Intermediate And Drive Assem

bly To Engine for detailed information.

PAGE B - 8 INSTALLATION

10 SERIES

OM-01604

OPERATION - SECTION C

Review all SAFETY information in Section A.

Follow the instructions on all tags, labels and decals attached to the pump.

Do not operate an internal combustion engine in an explosive atmosphere. When operating internal combustion engines in an enclosed area, make cer tain that exhaust fumes are piped to the outside. These fumes contain carbon monoxide, a deadly gas that is color less, tasteless, and odorless.

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 2200 RPM.

PRIMING

Install the pump and piping as described in IN STALLATION. Make sure that the piping connec

tions are tight, and that the pump is securely mounted. Check that the pump is properly lubri cated (see LUBRICATION in MAINTENANCE AND REPAIR).

This pump is self‐priming, but the pump should never be operated unless there is liquid in the pump casing.

Never operate this pump unless there is liquid in the pump casing. The pump will not prime when dry. Extended operation of a dry pump will destroy the seal assembly.

Add liquid to the pump casing when:

1. The pump is being put into service for the first time.

2. The pump has not been used for a consider able length of time.

3. The liquid in the pump casing has evapo rated.

Once the pump casing has been filled, the pump will prime and reprime as necessary.

After filling the pump casing, reinstall and tighten the fill plug. Do not attempt to operate the pump unless all connect ing piping is securely installed. Other wise, liquid in the pump forced out un der pressure could cause injury to per sonnel.

To fill the pump, remove the pump casing fill cover or fill plug in the top of the casing, and add clean liquid until the casing is filled. Replace the fill cover or fill plug before operating the pump.

NOTE

This pump is self‐priming; however, it is not suited for unattended reprime applications. In the event of suction check valve failure and loss of prime, the pump casing must be refilled through the fill cover or fill plug.

When installed in a flooded suction application, simply open the system valves and permit the in coming liquid to evacuate the air. After the pump

OPERATION PAGE C - 1

OM-01604 10 SERIES

and piping system have completely filled, evacu ate any remaining air pockets in the pump or suc tion line by loosening a pipe plug or opening bleeder valves.

STARTING

If the pump is equipped with the option al automatic starting system, it is sub ject to automatic restart. Keep hands and clothing away from the unit to pre vent injury during automatic operation. Disconnect the positive battery cable before performing any maintenance. Failure to do so may result in serious personal injury.

Consult the operations manual furnished with the engine.

Starting

line. Air from the suction line will be discharged through the bypass line back to the wet well during the priming cycle. When the pump is fully primed and liquid is flowing steadily from the bypass line, open the discharge throttling valve. Liquid will then continue to circulate through the bypass line while the pump is in operation.

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 pres sure 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.

On initial start‐up, set the engine speed at the half‐ throttle position. Turn the keyswitch on the control box to the “START” position until the engine starts. Release the key and the switch will return to the “RUN” position.

After the engine starts and the unit is fully primed, adjust the engine RPM until the desired flow rate is achieved.

Pump speed and operating condition points must be within the continuous per formance range shown on the curve on page E‐1.

OPERATION

Lines With a Bypass

Leakage

No leakage should be visible at pump mating sur faces, or at pump connections or fittings. Keep all line connections and fittings tight to maintain maxi mum 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 rup ture or explode. If overheating occurs, stop the pump and allow it to cool before servicing it. Refill the pump casing with cool liquid.

Close the discharge throttling valve (if so equipped) so that the pump will not have to prime against the weight of the liquid in the discharge

Do not remove plates, covers, gauges,

pipe plugs, or fittings from an over heated pump. Vapor pressure within the pump can cause parts being disen gaged to be ejected with great force. Al low the pump to completely cool before servicing.

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 in stalled, 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 neces sary, liquid pressure must be limited to 50% of the maximum permissible operating pressure shown on the pump performance curve. (See Section E, Page 1.)

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 oper ating speed the pump should pull a vacuum of 20 inches (508,0 mm) or more of mercury. If it does not, check for air leaks in the seal, gasket, or dis charge 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

Stopping

Reduce the throttle speed slowly, and allow the en gine 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, close and lock the control panel cover, or disconnect the positive battery cable to ensure that the pump will remain inopera tive.

Safety Shutdown System

The unit is equipped with a safety system to auto matically shut down the engine under certain con ditions. The engine will automatically shut down:

1. If the engine exceeds its safe operating tem perature.

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

3. If the engine fails to start within a pre‐set peri od of time.

4. If the engine speed exceeds the safe operat ing 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.

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 HAND‐OFF‐ AUTO switch has been returned to the `OFF' posi tion for at least 10 seconds.

All safety shutdown features are pre‐set at the fac tory for optimum performance and safety; do not attempt to adjust these settings.

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.

Never disconnect any of the safety shut

OM-01604 10 SERIES

down features; this will void the warran ty and could result in serious damage to the unit and/or injury to personnel. Safe ty 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 ad ditional information.

OPERATION IN EXTREME HEAT

The safety shutdown system will automatically stop the unit if engine operating temperature ex ceeds design limits. If engine over‐temperature shutdown occurs, allow the unit to cool before re starting.

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 al low shorter run and longer cooling periods, if pos sible.

If the pump is equipped with the option al automatic starting system, it is sub ject to automatic restart. Keep hands and clothing away from the unit to pre vent injury during automatic operation. Disconnect the battery before perform ing any maintenance. Failure to do so may result in serious personal injury.

BEARING TEMPERATURE CHECK

Bearings normally run at higher than ambient tem peratures 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 inaccu rate. Bearing temperatures can be measured ac curately 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 cor rect level (see LUBRICATION in Section E). Bear ing 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. Con tinued operation should bring the temperatures down to normal levels.

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 rotat ing parts. If the pump will be idle for more than a few hours, or if it has been pumping liquids con taining 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 pre venting 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.

OPERATIONPAGE C - 4

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 pre ventive maintenance schedule will help assure trouble‐free performance and long life from your Gorman‐Rupp pump. For specific questions con cerning your application, contact your Gorman‐ Rupp 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 inspec tions can indicate problems that can be corrected before system damage or catastrophic failure oc curs. 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 inspec tions 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 be comes necessary to inspect or replace the wearing parts, follow these instructions which are keyed to the illustrations (see Figures 1 through 3) and the accompanying parts lists.

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.

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 cau tiously.

7. Drain the pump.

Back Cover Removal

(Figure 2)

Most service functions, such as wear plate, impel ler, and seal replacement, may be performed by draining the pump and removing the back cover assembly. However, the following instructions as sume complete disassembly is required.

Before attempting to service the pump, switch off the engine ignition and disconnect the positive bat tery cable to ensure that the pump will remain inop erative. Close all valves in the suction and dis charge lines.

For engine disassembly and repair, consult the lit erature supplied with the engine, or contact your local Deutz engine representative.

Before attempting to open or service the pump:

1. Familiarize yourself with this man ual.

Before attempting to service the pump, remove the pump casing drain plug (60) and drain the pump. Clean and reinstall the drain plug. The wear plate (57) and check valve (79) are easily accessible and may be serviced by removing the back cover as sembly (62).

Remove the cover clamp screw (67) and clamp bar (68) securing the back cover. Pull the back cover and assembled wear plate from the pump casing (1). Inspect the back cover gasket (61) and replace it if damaged or worn.

Inspect the wear plate and replace it if badly scored or worn. To remove the wear plate, disengage the hardware (58 and 59).

Suction Check Valve Removal

(Figure 2)

If the check valve assembly (79) is to be serviced, reach through the back cover opening and hold the assembly in place while removing the check

valve pin (80). Slide the assembly out of the check valve seat (71) and remove it from the pump.

NOTE

Further disassembly of the check valve is not re quired since it must be replaced as a complete unit. Individual parts are not sold separately.

The check valve assembly may also be serviced by removing the suction flange (76). To remove the flange, disengage the hardware (74 and 75) and separate the flange from the check valve seat. Re move the machine screws (72) and pull the seat and assembled check valve from the suction port. Remove the check valve pin and pull the check valve assembly out of the seat.

Replace the flange gaskets (70 and 73) as re quired.

Separating Pump and Intermediate from Engine

As the assemblies separate, the flexible portion of the coupling assembly (3) will remain on the shaft. To remove the coupling from the shaft, unscrew the two allen head setscrews from the bushing (2). 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 (47, Figure 2).

It is not necessary to remove the outer ring of the coupling from the engine flywheel unless the cou pling must be replaced. To remove the ring, disen gage the hardware (4 and 5) securing it to the fly wheel.

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 3)

If the impeller or seal assembly require replace ment, the pump end and drive assembly must be separated from the engine.

Support the pump using a suitable hoist and sling. Remove the hardware (7, 8, 9 and 10, Figure 1) se curing the pump casing (1) to the base (1, Figure

1).

Disengage the hardware (6 and 7) securing the drive assembly to the intermediate. Separate the pump end and drive assembly from the engine by pulling the pump end straight away from the en gine.

(Figure 2)

Before loosening the impeller (2), drain the seal lu bricant by removing the seal drain plug (53). This will prevent the oil from escaping when the impeller is removed. Clean and reinstall the drain plug.

Reach through the suction port and wedge a block of wood between the vanes of the impeller and the pump casing to prevent rotation.

If removed, install the shaft key (46) in the shaft keyway. Install a lathe dog on the drive end of the shaft (47) with the “V” notch positioned over the shaft key.

With the impeller rotation still blocked, see Figure 4 and use a long piece of heavy bar stock to pry against the arm of the lathe dog in a counterclock wise direction (when facing the drive end of the shaft). Use caution not to damage the shaft or key way. When the impeller breaks loose, remove the lathe dog, key and wood block.

NOTE

Do not remove the impeller until the rotating assem bly has been removed from the pump casing.

Place a block of wood against the impeller end of the shaft (47), and tap the shaft and assembled bearings (50 and 52) from the intermediate. Press the inboard oil seal (56) from the intermediate.

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

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.

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

tation 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 intermedi ate. Replace the bearings, shaft, or intermediate if the proper bearing fit is not achieved.

If bearing replacement is required, use a bearing puller to remove the inboard and outboard bear ings (18 and 29) from the shaft.

Shaft and Bearing Reassembly and Installation

(Figure 2)

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 (56) in the intermediate housing bore with the lip positioned as shown in Figure 2. Press the oil seal into the housing until the face is just flush with the machined surface on the housing.

Clean and inspect the bearings as indicated in

Shaft And Bearing Removal And Disassembly.

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.

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 great ly shorten bearing life. Do not spin dry bearings. This may scratch the balls or races and cause premature bearing fail ure.

Rotate the bearings by hand to check for rough ness or binding and inspect the bearing balls. If ro

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. Bear ings should never be heated with a direct flame or directly on a hot plate.

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

Securing Intermediate And Drive Assembly To Engine

(Figure 3)

Install the shaft key (46, Figure 2) in the shaft key way. Position the flexible portion of the coupling as sembly (3) on the shaft as shown in Figure 3.

NOTE

The flexible portion of the coupling must be proper ly positioned on the shaft. The heads of the caps crews in the center of the coupling must be posi tioned toward the pump end of the shaft.

When installing the shaft and bearings into

MAINTENANCE & REPAIR PAGE E - 11

housing with the previously removed hardware (6 and 7).

Make certain that the flexible portion of the coupling is mounted to the dimension shown in Figure 3. This dimension is crit ical. If the coupling is not properly posi tioned on the shaft, the coupling parts may not fully engage, or a pre‐load condition can cause premature bearing failure.

The end of the bushing must be just flush from the end of the shaft. This will allow the two portions of the coupling to fully engage when the intermediate is secured to the en gine 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 14.5 ft. lbs. (175 in. lbs. or 2,02 m. kg.).

Seal Reassembly and Installation

(Figures 2 and 5)

Clean the seal cavity and shaft with a cloth soaked in fresh cleaning solvent.

The seal is not normally reused because wear pat terns on the finished faces cannot be realigned during reassembly. This could result in premature failure. If necessary to reuse an old seal in an emer gency, carefully wash all metallic parts in fresh cleaning solvent and allow to dry thoroughly.

If the complete coupling assembly is being re placed, apply `Loctite Retaining Compound No. 242' or equivalent compound to the threads of the hardware (4 and 5), 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.).

Using a suitable lifting device, position the as sembled coupling, intermediate, shaft and bear ings so the flexible portion of the coupling seats in side the outer ring attached to the engine flywheel.

NOTE

To ease installation, lightly lubricate the rubber por tion of the coupling with a non‐petroleum based lubricant such as vegetable oil or glycerin, or a sili con‐based lubricant such as “WD40” or equivalent. Do not use petroleum‐based lubricants, or any oth er substance which may soften or otherwise dam age the rubber.

Install the intermediate guards (40 and 41, Figure

2), and secure the intermediate to the engine bell

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.

Inspect the seal components for wear, scoring, grooves, and other damage that might cause leak age. Clean and polish the shaft sleeve, or replace it if there are nicks or cuts on either end. If any com ponents are worn, replace the complete seal; never mix old and new seal parts.

If a replacement seal is being used, remove it from the container and inspect the precision finished faces to ensure that they are free of any foreign matter.

To ease installation of the seal, lubricate the O‐ rings, sleeve, and bellows with water or a very small amount of oil, and apply a drop of light lubri cating oil on the finished faces. Assemble the seal as follows, (see Figure 5).

Inspect the impeller, and replace it if cracked or badly worn.

The shaft and impeller threads must be completely clean before reinstalling the im peller. 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 im peller or shaft.

Install the same thickness of impeller adjusting shims (32) as previously removed, and screw the impeller (2) onto the shaft until tight.

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.

10 SERIESOM-01604

NOTE

An alternate method of adjusting this clearance is to reach through the discharge port with a feeler gauge and measure the gap. Add or subtract pump casing gaskets accordingly.

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

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

Remove the two capscrews temporarily holding the seal plate, and install the same thickness of casing gaskets (55) as previously removed. Se cure the seal plate and pump casing to the inter mediate with the nuts (16). Do not fully tighten the nuts until the impeller face clearance has been set.

NOTE

If the pump has been completely disassembled, it is recommended that the wear plate (57) and back cover assembly (62) be reinstalled at this point. The back cover and wear plate must be in place to ad just the impeller face clearance.

Suction Check Valve Installation

(Figure 2)

Inspect the check valve assembly (79), and re place it if badly worn.

NOTE

The check valve assembly must be replaced as a complete unit. Individual parts are not sold sepa rately.

Replace the seat gasket (70) and secure the check valve seat (71) to the pump casing with the round head machine screws (72).

NOTE

If the suction flange or check valve seat was re moved, replace the respective gaskets, and apply `Permatex Aviation No. 3 Form‐A‐Gasket' or equiva lent compound to the mating surfaces.

A clearance of .010 to .020 inch (0,25 to 0,51 mm) between the impeller and the wear plate is also rec ommended for maximum pump efficiency. This clearance must be set after installing the back cover, by adding or removing gaskets in the pump casing gasket set (55) until the impeller scrapes against the wear plate when the shaft is turned. Af ter the impeller scrapes, add approximately .010 inch (0,25 mm) of gaskets.

Reach through the back cover opening with the as sembled check valve, and position the check valve adaptor in the mounting slot in the check valve seat. Align the adaptor with the seat hole, and se cure the assembly with the check valve pin (80).

Replace the suction flange gasket (73). Secure the suction flange (76) to the check valve seat and pump casing with the hardware (74 and 75).

Back Cover Installation

(Figure 2)

If the wear plate (57) was removed for replace ment, carefully center it on the back cover (63) and secure it with the hardware (58 and 59). The wear plate must be concentric to prevent binding when the back cover is installed.

Clean any scale or debris from the contacting sur faces in the pump casing that might interfere or prevent a good seal with the back cover. Replace the back cover gasket (61) and slide the back cover assembly (62) into the pump casing. Be sure the wear plate does not bind against the impeller.

NOTE

To ease future disassembly, apply a film of grease or `Never‐Seez' on the back cover shoulder, or any surface which contacts the pump casing. This ac tion will reduce rust and scale build‐up.

LUBRICATION

Seal Assembly

(Figure 2)

Fill the bottle oiler (34) with SAE No. 30 non‐deterg ent motor oil, making certain to vent the seal cavity at the air vent (17) while filling. Check the oil level regularly and keep the bottle oiler full.

Bearings

(Figure 2)

The intermediate was fully lubricated when shipped from the factory. Check the oil level regu larly through the sight gauge (39) the middle of the gauge. When lubrication is re quired, add SAE No. 30 non‐detergent oil through the hole for the oil hole cover (20). Do not over‐lu bricate. Over‐lubrication can cause the bearings to over‐heat, resulting in premature bearing failure.

and maintain it at

Secure the back cover assembly by tightening the cover clamp screw (67) against the clamp bar (68). Do not over‐tighten the clamp screw; it should be just tight enough to ensure a good seal at the back cover shoulder.

Final Pump Assembly

(Figure 1)

Install any leveling shims used under the pump casing mounting feet and secure the casing (1, Figure 2) to the base (1) with the hardware (7, 8, 9 and 10). Be sure the pump is secured to the base and engine.

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 end and engine have been properly lubricated, see LUBRICATION.

(Figure 2)

Remove the fill cover assembly (24). Fill the pump casing with clean liquid. Reinstall the fill cover plate and gasket (28), and tighten the cover.

NOTE

The white reflector in the sight gauge must be posi tioned horizontally to provide proper drainage.

Under normal conditions, drain the intermediate once each year and refill with approximately 7.5 ounces (22 mL) of clean oil. Change the oil more frequently if the pump is operated continuously or installed in an environment with rapid temperature change.

Monitor the condition of the bearing lubri cant regularly for evidence of rust or mois ture condensation. This is especially im portant 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.
