INTRODUCTION
Thank You for purchasing a Gorman-Rupp Self-
Priming Centrifugal 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.
A set of three manuals accompanies your pump. Each set consists of three parts; the Operation Manual on installing and operating the pumps. However, since pump installations are seldom identical, some of the information only summarizes general recommendations and practices required to in­spect, position, and arrange the pump and piping.
The Parts List Manual curve(s), a pump model cross-section drawing, and parts list for your pump.
The Maintenance and Repair Manual troubleshooting and maintenance instructions re­quired to properly diagnose operational problems, and to service the pump components.
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 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 ac- cording to all national, local and industry stan­dards.
If there are any questions regarding the pump which are not covered in this manual or in other lit­erature accompanying the unit, please contact your Gorman-Rupp distributor or the Gorman­Rupp Company:

SAFETY - SECTION A
This information applies to the VGH Se­ries Basic Pumps. These pumps are ba ­sic, pedestal -mounted model and may be driven by either an electric motor, gasoline or diesel engine. Refer to the manual accompanying the power source before attempting to begin oper­ation.
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, thismanual cannot possibly antici ­pate and provide detailed instructions and 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 main­tenance procedures are used, and that any procedures not addressed in this manual are performed only after estab­lishing that neither personal safety nor pump integ rity are compromised by such practices.
In addition to this manual, see the sepa­rate literature covering maintenance and repair, pump parts, and any optional equipment shipped with the pump.
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 attempt to pump any liqui d s the pump has not been designed for, and which may damage the pump or endan­ger personnel as a result of pump fail­ure. Consult the factory to determine compatibilitybetween the pump and liq­uid.
Use lifting and moving equipment in good repair and with adequate capacity to prevent injuries to personnel or dam­age to equipment. Suction and dis­charge 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 man­ual.
2. Disconnect or lock out the power source and take necessary pre­cautions to en sure that the pump will remain inoperative.
3. Allow the pump to completely cool if overheated.
After the pump has been positioned, make c ertain that the pump and all pip­ing or hose connections are tight, prop ­erly supported and secure before oper­ation.
Do not operate the pump against a closed discharge valve for long periods oftime.Ifoperatedagainstacloseddis­charge valve, pump components will deteriorate, and the liquid could come

to a boil, build pressure, and cause the pump casing to rupture or e xplode.
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 cool before servicing.
Never run this pump backwards. Be cer­tain that rotation is correct before fully engaging the pump.
tools, causing severe injury to person­nel.
If the pump is powered by an electric motor, do not operate a non-explosion proof motor in an explosive atmo­sphere. An explosion, which may cause severe personal injury or death, could result. Install, connect and operate the motor in accordance with the National Electric Code and all local codes. If there is a c onflict between the instruc­tions in the manual accompanying the unit and the National Elec tric Code or applicable local code, the National or Local code shall take precedence. All electrical equipment supplied with the pump conforms to applicable federal regulations and national codes in effect on the date of manufacture.
If the p ump i s used to pump m aterials which c ould cause serious illness or in ­jury through di rect exposure or emitted fumes, wear protective clothing, such as rubber gloves, face mask, and rubber apron, as necessary before disassem­bling the pump or piping.
Do not operate the pump without shields and/or guards in place over the drive shafts, belts, and/or couplings, or other rotating parts. Exposed rotating parts can catch clothing, fingers, or
If the pump is electric motor driven, the electrical power used t o operate the pump is high enough to cause injury or death. Obtain the services of a qualified electrician to trouble shoot, test and/or service the electrical components of this pu mp.
Pumps and related equipment must be in­stalled and operated according to all na­tional, local and industry standards.

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 ar ­range 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 (see Parts List Manual).
For further assistance, contact your Gorman-Rupp distributor or the Gorman-Rupp Company.
c. Carefully read all tags, decals, and markings
on the pump assembly, and perform all duties indicated. Note that the pump shaft rotates in the required direction.
d. Check levels and lubricate as necessary. Re-
fer to LUBRICATION in the MAINTENANCE AND REPAIR section of this manual and any other literature accompanying the unit and perform duties as instructed.
e. If the pump and power s ource have been
stored for more than 12 months, some of the components or lubricants may have ex­ceeded their maximum shelf life. These must be inspected or replaced 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 deter­mine the repair or updating policy. Do not put the pump into service until appropriate action has been taken.
Pump Dimensions
See the individual pump specification data sheet for the approximate physical dimensions of the pump.
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 and power source (if so
equipped) 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.
POSITIONING PUMP
Lifting
Use lifting equipment with a capacity of at least 5 times the weight of the pump, not including the
weight of accessories, or optionalequipment. Cus­tomer installed equipment such as suction and dis­charge pipingmust be removed before attempting to lift.
Thepumpassemblycanbeseriously damaged if the chains or cables used to lift and move the unit are improperly wrapped around the pump.
See the individual pump specification data sheet for the approximate weight of the pump.
