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
pump hydraulic, priming and drive components
only. The pump assembly may be close-coupled to
either a factory-supplied or customer-supplied en-
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
Use lifting equipment with a capacity of
at least
five times the weight of the component being
lifted
. When lifting the complete unit, the lifting
equipment must also be capable of lifting the
weight of any options or customer-installed acces-
sories. Suction and discharge hoses or piping
must
be removed before attempting to lift the
pump.
For the approximate weight of your pump, refer to
the pump specification data sheet or contact your
Gorman-Rupp distributor or the Gorman-Rupp
Company.
