INTRODUCTION
Thank You for purchasing a Gorman-Rupp SM
Series 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.
A set of three manuals accompanies your pump.
Each set consists of three parts; the Installation/
Operation Manual contains essential information
on installing and operating the pump, and on making electrical connections. However, since pump
installations are seldom identical, some of the information only summarizes general recommendations and practices required to inspect, position,
and arrange the pump and piping.
The Parts List Manual provides performance
curve(s), a pump model cross-section drawing,
and parts list for your pump.
The Maintenance and Repair Manual provides
troubleshooting and maintenance instructions required to properly diagnose operational problems,
and to service the pump hydraulic components.
Pump motor maintenance 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.
The integral electric motor must be operated
through the control box furnished with the pump.
The pump and control comply with MSHA sched-
ule 2G regulations. Control boxes and other control devices are not covered in this manual.
Pump construction may be aluminum or stainless
steel. The pump may be operated fully or partially
submerged, since the integral air-filled electric motor is thermally protected and cooled by the liquid
being pumped.
Because pump installations are seldom identical,
this manual cannot possibly provide detailed instructions and precautions for every aspect of
each specific application. Therefore, it is the responsibility of the owner/installer of the pump to
ensure that applications not addressed in this
manual are performed only after establishing that
neither operator safety nor pump integrity are compromised by the installation. Pumps and related
equipment must be installed and operated according to all national, local and industry standards.
If there are any questions regarding the pump
which are not covered in this manual or in other literature accompanying the unit, please contact
your Gorman-Rupp distributor or the GormanRupp Company:

PREINSTALLATION INSPECTION
The pump and control box were inspected and
tested before shipment from the factory. Before installation, inspect the pump for damage which may
have occurred during shipment. Check as follows:
h. Check the pump and motor for any oil leaks.
An oil leak may indicate a cut O-ring or other
damage.
i. If the pump and
control box have been stored
for more than 12 months, some of the components or lubricants may have exceeded their
maximum shelf life. These must be inspected
or replaced to ensure maximum pump service.
If the maximum shelf life has been exceeded, or if
anything appears to be abnormal, contact your
Gorman-Rupp distributor or the factory to determine the repair or updating policy. Do not put the
pump into service until appropriate action has
been taken.
LUBRICATION
a. Inspect the pump assembly for cracks, dents,
damaged threads, and other obvious damage.
b. Check for and tighten loose attaching hard-
ware. Since gaskets tend to shrink after drying, check for loose hardware at mating surfaces.
c. The standard pump is furnished with 50 feet of
power cable. Inspect the cable for cuts or
damage.
d. Inspect the control box for cracks, dents, and
other obvious damage.
e. Check that all control box components are se-
curely attached to their mounting surfaces,
and the electrical connections are tight and
free of corrosion.
f. Compare the amperes, phase, voltage and
hertz indicated on the motor nameplate to the
ratings indicated for the control box.
This pump series utilizes one lubrication cavity, located just behind the seal plate. It is filled with premium quality submersible pump oil which lubricates two shaft seals. The motor operates in air
and requires no lubrication.
The lower shaft seal prevents liquid from entering
the lubrication cavity, while the upper shaft seal
prevents oil leakage into the motor. The upper seal
also acts as backup protection in the event of lower
seal failure.
The lubrication cavity was fully lubricated when
shipped from the factory. Check the oil level before
installing the pump (see LUBRICATION in MAIN-
TENANCE AND REPAIR). An additional quart of
oil has been provided with the pump to top off" the
oil cavity. If the oil level is abnormally low, determine the cause before putting the pump into service.
PUMP SPECIFICATIONS
g. Carefully read all tags, decals, and markings
on the pump assembly and the control box,
and perform all duties as indicated.
See Tables B-1 and B-2 for pump specifications
and motor data.
