PAGE I − 1INTRODUCTION

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 0 Series, enclosed impeller, cen-

trifugal model, with straight-in suction and without

a suction check valve. It is designed for vehicular

mounting in petroleum service. The basic material

of construction is aluminum, with cast iron wear

rings.

The pump is close-coupled to an integral, 1950

RPM split-shaft gearbox speed increaser with a

2.56:1 ratio. Power is transmitted to the gearbox

through a customer-installed universal shaft as-

sembly.

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.

For information or technical assistance on the pow-

er source, contact the power source manufactur-

er’s local dealer or representative.

If there are any questions regarding the pump or

its application which are not covered in this man-

ual or in other literature accompanying this unit,

please contact your Gorman-Rupp distributor, or:

SAFETY − SECTION A

This information applies to 0 Series

split-shaft refueler pumps. Gorman-

Rupp has no control over or particular

knowledge of the truck chassis which

will be used. Refer to the manual ac-

companying the truck before attempt-

ing 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 open or service the

pump:

1. Familiarize yourself with this man-

ual.

2. Switch off the vehicle ignition and

remove the key, or take other ac-

tion to ensure that the pump will re-

main 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.

This pump is designed for vehicular

mounting in petroleum service. Do not

attempt to pump corrosive materials, or

any liquids which may damage the

pump or endanger personnel as a result

of pump failure.

Be certain proper safety practices are

followed before operating or servicing

the pump. Provide adequate ventilation,

prohibit smoking, wear static-resistant

clothing and shoes. Clean up all fuel

spills immediately after occurrence.

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.

Overheating may produce dangerous

fumes. Take precautions to ensure the

area surrounding the pump is ade-

quately ventilated. Allow the pump to

cool and use extreme caution when

venting the pump, or when removing

covers, plates, plugs, or fittings.

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 cool before servicing.

PAGE A − 2 SAFETY

After the vehicle is positioned for pump

maintenance, block the wheels and set

the emergency brake before attempting

to disconnect the drive shaft or remove

the pump. Be sure the pump is properly

reinstalled and secure before opera-

tion.

Never tamper with the governor to gain

more power. The governor establishes

safe operating limits that should not be

exceeded. Limit the maximum input

speed (1950 RPM) and performance as

indicated on the performance curve on

Page E-1.

The gearbox provided on this pump is

designed for operation at a maximum in-

put speed of 1950 RPM. If operated at a

higher RPM, pump or gearbox compo-

nents may be destroyed.

Decals and tags vital to pump operation

were shipped loose with the pump. Affix

these decals in a prominent place vis-

ible to the pump operator.

Decals and tags vital to pump operation

were shipped loose with the pump. Affix

these decals in a prominent place vis-

ible to the pump operator.

Never run the pump dry of pumping me-

dium. There must be a supply of liquid to

the pump at all times to prevent destruction

of the shaft seal faces.

This pump has been shipped dry of gear-

box lubrication, except for a residual coat-

ing from the testing process of 90 weight

gear oil and Dow Corning MolykoteM

Gear Guard" (an anti-wear additive, con-

sisting of molybdenum disulphide solid lu-

bricants suspended in petroleum oil). The

gearbox must be lubricated before the

pump is operated (see LUBRICATION in

Section E).

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.

Do not test or operate this pump and in-

tegral gearbox before reading the in-

stallation and operation instructions on

this manual.

This pump is an 0 Series, self-priming centrifugal

model with an integral split-shaft gearbox assem-

bly. The entire unit is designed for midship mount-

ing between the frame members of a petroleum

handling vehicle, where the liquid is supplied to the

pump under pressure. The gearbox replaces a

part of the main drive shaft connecting the trans-

mission to the rear axle.

This design permits full utilization of engine power

to selectively operate either the pump or the rear

driving wheels on the vehicle. Both cannot be op-

erated at the same time.

For further assistance, contact your Gorman-Rupp

distributor or the Gorman-Rupp Company.

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 and gearbox 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 tags, decals, and markings

on the pump assembly, and perform all duties

indicated. Note the direction of rotation indi-

cated on the pump. Check that the pump

shaft rotates in the required direction.

Only operate this pump in the direction in-

dicated on the gearbox and/or the accom-

panying decal. Reverse rotation of the

shaft will adversely effect pump perform-

ance, and the pump and/or gearbox could

be seriously damaged.

d. The gearbox assembly was shipped dry of

lubricant. Refer to LUBRICATION in the

MAINTENANCE AND REPAIR section of this

manual and perform duties as instructed.

e. If the pump and gearbox have been stored for

more than 12 months, some of the compo-

nents or lubricants may have exceeded their

maximum shelf life. These must be inspected

or replaced to ensure maximum pump serv-

ice.

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.

Pump and Mounting Dimensions

A 40 inch (1016 mm) cross member is provided for

mounting the output end of the gearbox, and a

trunnion mount is provided for the input end. This

design provides a flexible three-point suspension.

The trunnion mount prevents the chassis frame

twist from being transmitted through the gearbox.

See Figure 1 on page B−3 and Figure 2 on page

E−4 for the physical dimensions of the pump.
