For information or technical assistance on the engine, contact the engine manufacturer’s local dealer or representative.
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:
weight design for portability, as well as rugged construction for easy, low-cost maintenance. The basic material of construction for wetted parts is aluminum w ith bronze wear ring, and a self lubri­cated mechanical seal.

SAFETY --- SECTION A
This information applies to 60 Series Engine Drivenpumps. Refer to theman­ual accompanying the engine be fore at­tempting to beg in operation.
This manual will alert personnel to known procedures which require spe­cial attention, to those which c ould damage equipment, and to thosewhich could be dangerous to personnel.How­ever, thismanualcannotpossiblyantici­pate and provide detailed instructions and precautions for every situationthat might occur during maintenance of the unit.Therefore,itisthe responsibility of the owner/maintenance personnel to ensurethatonlysafe, established main­tenance 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.
Beforeattemptingto openorservicethe pump:
This pump is designed to handle clear water for high pressure distribution. Do not attempt to pump volatile,corrosive,
or flammable liquids which may dam­agethepump orendanger personnel as a result of pump failure.
Do not operate the pump against a closed discharge valve for long periods of time. This could bring the liquid 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. Vaporpressure withinthe pump can cause parts being disen­gagedtobe ejectedwith great force.Al­low the pump to cool before servicing.
1. Familiarize yourself with thisman­ual.
2. Shutdown the engine and discon­nect the park plug wires to ensure that the pump will remain inopera­tive.
3. Allowthe pump tocompletely 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.
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 tothe outside. These fumes contain carbon monoxide, a deadly gas that is color­less, tasteless, and odorless.
Fuel used by internal combustion en­gines 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 run­ning engine. Avoid overfilling the fuel tank.Alwaysusethe correcttype offuel.

Never tamper with the governor to gain more power. The governor establishes safe operating limits that should not be exceeded.
PAGE A -- 2 SAFETY
INSTALLATION --- SECTION B
OM--0517160 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 ar­range the pump and piping.
Most of the information pertains to a standard
static lift application where the pump is posi­tionedabovethefreelevelofliquidto bepumped.
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 shownon thepump performance curve. (SeeSec­tion E, Page 1.)
Forfurtherassistance, contact yourGorman-Rupp distributor or the Gorman-Rupp Company.

PREINSTALLATION INSPECTION
Thepump assemblywas inspectedandtested be­fore shipment from the factory. Before installation, inspect the pump for damage which may haveoc ­curred during shipment. Check as follows:
a. Inspect thepumpforcracks, 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.

OM--05171 60 SERIES
c. Carefully read all tags, decals and markings
onthepumpassembly,andfollowtheinstruc­tions indicated.
d. Check all lubricant levels and lubricate as
necessary. Refer to LUBRICATION in the MAINTENANCE AND REP AIRsectionof this manual and perform duties as instructed.
e. If the pump and engine have been stored for
more than 12 months, some of the compo­nents or lubricants may have exceeded their maximumshelflife.These mustbeinspected or replaced to ensure maximum pump serv­ice.
f. Check to ensure the following standard
equipment items are included with the pump assembly:
S Portable 6.5 gallon fuel tank complete with
quick-connect fitting.
S Suction strainer. S Rubber foot mounting kit (must be
installed). Toinstall feet, positionflatwash­ers on capscrews, slide the capscrews through the rubber feet and holes in the base,and secure withtheflanged hexnut.
If the maximum shelf life has been exceeded, or if anything appears to be abnormal, contact your Gorman-Rupp distributor or the factory to deter­mine the repair or updating policy. Do not put the pump into service until appropriate action has been tak en.
POSITIONING PUMP
This pump is designed to be very light-weightand portable. The total pump weight is approximately 240 pounds (109 kg), not including accessories orengine fuel.Customer installedequipment such as suctionand discharge hoses must be removed before attempting to lift.
Mounting
Locatethepump inanaccessibleplaceascloseas practicalto the liquidbeingpumped. Levelmount­ing is essential for proper operation.
To ensure sufficient lubrication and fuel supply to the engine, do not position the pump and engine morethan 15_ off horizontal for continuous opera­tion. The pump and engine may be positioned up to 30_ off horizontal for intermittent operation only;however,theengine manufacturershould be consulted for continuous operation at angles greater than 15_.
SUCTION AND DISCHARGE PIPING
Pump performance is adversely effected by in­creased suction lift, discharge elevation, and fric­tion losses. See the performance curve and oper­ating range shown on Page E-1 to be sure your overall application allows pump to operate within thesafeoperationrange.
Materials
Either pipe or hose maybe used for suction and discharge lines; however, the materials must be compatiblewiththe liquidbeingpumped. Ifhoseis 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.
Line Configuration
Keep suction and discharge lines as straight as possible to minimize friction losses. Make mini­mum use of elbows and fittings, which substan­tiallyincreasefrictionloss. Ifelbows arenecessary, use the long-radius type to minimize friction loss.
Connections to Pump
Before tightening a connecting flange, align it ex­actlywith the pump port. Never pulla pipe lineinto 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 linesare used,they shouldhaveadequatesupport to secure them when filled with liquid and under pressure.
The pump may have to be supported orshimmed to provide for level operation or to eliminate vibra­tion.
