PUMP MAINTENANCE AND REPAIR - SECTION E
GENERAL INFORMATION
Review all SAFETY information in Section A.
Do not attempt to service the pump as­
sembly unless all power to the motor
has been shut off at the control box;
otherwise, injury or death could result.
Select a suitable location, preferably indoors, to
perform required maintenance. All work must be
performed by qualified personnel.
The motor powering this pump is ap­
proved by either CSA and/or FM for Class
1, Division 1, Groups C and D environ­
ments. Refer to the nameplate on your
pump for agency approval information. All
repairs to the pump, other than seal, impel­
ler and other hydraulic components, must
be performed by a Gorman‐Rupp autho­
rized repair facility or the factory. Any re­
pairs to the motor assembly performed by
the customer or an unauthorized repair fa­
cility negates the agency approval and the
motor warranty.
Check TROUBLESHOOTING, Section D to deter­
mine causes and remedies of pump problems.
This section of the manual provides maintenance
instructions required to properly service the pump
hydraulic components only. Pump motor mainte­
nance may be performed only by a Gorman‐Rupp
authorized repair facility, or the factory. Otherwise,
the pump warranty will be negated, and damage
to the pump, and injury or death to personnel can
result. Contact the factory for the authorized repair
facility closest to you.
Lifting
Death or serious personal injury and
damage to the pump or components
can occur if proper lifting procedures
are not observed. Make certain that
hoists, chains, slings or cables are in
good working condition and of suffi­
cient capacity and that they are posi­
tioned so that loads will be balanced
and the pump or components will not be
damaged when lifting. Do not attempt to
lift this pump by the motor or control
cables, or the piping. Attach proper lift­
ing equipment to the lifting bail fitted on
the pump. Lift the pump or component
only as high as necessary and keep per­
sonnel away from suspended objects.
Pump unit weights will vary depending on the
pump application. Check the shipping tag on the
unit packaging for the actual weight, and use lifting
equipment with appropriate capacity. Drain the
pump and remove all customer‐installed equip­
ment such as discharge hoses or piping before at­
tempting to lift existing, installed units.
Pump Serial Numbers
Pumps in the following serial number range are
covered in this section.
(From S/N 1531245 Up)
If your pump serial number is followed by an “N”,
your pump is NOT a standard production model.
Contact the Gorman‐Rupp Company to verify part
numbers.
