SAFETY − SECTION A
The following information applies
throughout this manual to Gorman-
Rupp Prime AireRSeries pumps.
This manual will alert personnel to
known procedures which require spe-
cial attention, to those which could
damage equipment, and to those which
could be dangerous to personnel. How-
ever, this manual 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 main-
tenance procedures are used, and that
any procedures not addressed in this
manual are performed only after estab-
lishing that neither personal safety nor
pump integrity are compromised by
such practices.
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.
Before attempting to open or service the
pump:
1. Familiarize yourself with this man-
ual.
2. Shut down the engine and discon-
nect the positive battery cable (en-
gine driven units) or lock out and
tag out incoming power to the con-
trol box (electric motor driven
units) and take precautions to en-
sure that the pump will remain in-
operative.
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 may be used to handle ma-
terials which could cause illness
through direct exposure or emitted
fumes. Wear adequate protective cloth-
ing when working on the pump or pip-
ing.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment. Attach lifting equip-
ment to the lifting device fitted to the
pump. If chains or cable are wrapped
around the pump to lift it, make certain
that they are positioned so as not to
damage the pump, and so that the load
will be balanced. The bail is intended for
use in lifting the pump assembly only.
Suction and discharge hoses and pip-
ing must be removed from the pump be-
fore lifting.

MR−05740 PA SERIES PUMPS
PAGE A − 2 SAFETY
After the pump has been installed, make
certain that the pump and all piping or
hose connections are tight, properly
supported and secure before operation.
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.
Overheated pumps can cause severe
burns and injuries, and produce explo-
sive fumes. If overheating of the pump
occurs:
1. Stop the pump immediately.
2. Ventilate the area.
3. Allow the pump to completely cool.
4. Check the temperature and make
sure it is cool before opening any
covers, plates, gauges, or plugs.
5. Vent the pump slowly and cau-
tiously.
6. Refer to instructions in the manu-
als accompanying the pump be-
fore restarting the pump.
Do not operate the pump without the
guards in place over the rotating parts.
Exposed rotating parts can catch cloth-
ing, fingers, or tools, causing severe in-
jury to personnel.
Use only replacement parts provided or
approved by Gorman-Rupp. Use of non-
authorized parts may result in damage to
the equipment and/or injury to personnel
and will invalidate the warranty.
Make sure the pump is level. Lower jack
stands and chock the wheels, if so
equipped. Use caution when positioning
the skid-mounted unit to prevent damage
to the fuel tank.
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 running en-
gine. Avoid overfilling the fuel tank. Al-
ways use the correct type of fuel.

SAFETY PAGE A − 3
Never tamper with the governor on en-
gine driven units to gain more power.
The governor establishes safe operat-
ing limits that should not be exceeded.
Refer to the pump Performance Curve
for the maximum continuous operating
speed.

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 MAINTENANCE AND REPAIR − SECTION C
Review all SAFETY information in Section A.
Follow the instructions on all tags, label and de-
cals attached to the pump.
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 operation or
maintenance could lead to destruction
of equipment, injury or death to person-
nel.
Use lifting and moving equipment in
good repair and with adequate capacity
to prevent injuries to personnel or dam-
age to equipment. If slings or chains are
used to move the pump or components,
make sure that the load is balanced;
otherwise serious personal injury or
death could result. 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.
The maintenance and repair instructions in this
manual are keyed to the sectional views and the
corresponding parts identification lists on the fol-
lowing pages. Refer to the separate Parts List Man-
ual for replacement parts.
This Maintenance and Repair Manual provides
troubleshooting instructions required to properly
diagnose operational problems. Maintenance in-
structions within this manual are limited to the

gine. Maintenance of engines and factory-supplied
air compressors are detailed in separate literature
provided by the manufacturer(s).
Check TROUBLESHOOTING, Section B to deter-
mine causes and remedies of pump problems.
Disassemble the pump only as far as required.
As described in the SAFETY Section, this manual
will alert personnel to known procedures which re-
quire special attention, to those which could dam-
age equipment, and to those which could be dan-
gerous to personnel. However, this manual cannot
possibly anticipate and provide detailed precau-
tions for every situation that might occur during
maintenance of the unit. Therefore, it is the respon-
sibility of the owner/maintenance personnel to en-
sure that only safe, established shop procedures
are used, and that any procedures not addressed
in this manual are performed only after establish-
ing that neither personal safety nor pump integrity
are compromised by such practices.
Select a suitable location, preferably indoors, to
perform required maintenance. All work must be
performed by qualified personnel.
Lifting
Pump unit weights will vary depending on the
