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. Lock out or disconnect the power
source 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.
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−05702 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 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.
Never tamper with the governor to gain
more power. The governor establishes

PA SERIES PUMPS MR−05702
SAFETY PAGE A − 3
safe operating limits that should not be
exceeded. Refer to the pump Perfor-
mance Curve for the maximum continu-
ous operating speed.
The electrical power used to operate
this pump is high enough to cause inju-
ry or death. Obtain the services of a qu-
alified electrician to make all electrical
connections. Make certain that the
pump and enclosure are properly
grounded; never use gas pipe as an
electrical ground. Be sure that the in-
coming power matches the voltage and
phase of the pump before connecting
the power source. Do not run the pump
if the voltage is not within the limits.
All electrical connections must be in ac-
cordance with The National Electric
Code and all local codes. If there is a
conflict between the instructions pro-
vided and N.E.C. Specifications, N.E.C.
Specifications shall take precedence.
Obtain the services of a qualified elec-
trician to troubleshoot, test and/or ser-
vice the electrical components of this
pump.

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 preventive maintenance schedule will help assure trouble-free performance
and long life from your Gorman-Rupp pump. For specific questions concerning 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 inspections can indicate
problems that can be corrected before system damage or catastrophic failure occurs. The appearance of
wearing parts should also be documented at each inspection for comparison as well. Also, if records indi-
cate 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 inspections should be performed at the intervals shown on the
chart below. Critical applications should be inspected more frequently.
