INSTALLATION - SECTION B
GENERAL INFORMATION
Review all SAFETY information in Section A.
Since pump installations are seldom identical, this
section is intended only to summarize general rec­
ommendations and practices required to inspect,
position, and arrange the pump and piping. If there
are any questions concerning your specific instal­
lation, contact your Gorman‐Rupp distributor or
the Gorman‐Rupp Company.
The pump motor is not designed to be
operated in air for more than 10 minutes
without overheating. The pump must be
operated through a liquid level control de­
signed to cut off power when liquid falls be­
low the midpoint of the motor housing
(single pump operation), or below the dis­
charge flange (duplex, alternating pump
operation).
Controls, liquid level devices, and a guide rail sys­
tem are available from Gorman‐Rupp as optional
equipment. For more information on installing and
operating these options, refer to the other literature
accompanying the option(s).
PREINSTALLATION INSPECTION
The pump assembly was inspected and tested be­
fore shipment from the factory. Before installation,
check for damage which may have occurred dur­
ing shipment. Check as follows:
a. Inspect the pump assembly for cracks, dents,
damaged threads, and other obvious dam­
age.
b. Check for loose attaching hardware. Since
gaskets tend to shrink after drying, check for
loose hardware at the mating surfaces.
c. Inspect the power cable for cuts or any other
obvious damage.
d. Check that amperes, phase, voltage and
hertz indicated on the name plate match the
ratings on the control box and incoming pow­
er.
e. Carefully read all tags, decals, and markings
on the pump, and perform all duties indicated.
f. Check for oil leaks. If there is any indication of
an oil leak, see LUBRICATION at the end of
this manual.
LUBRICATION
These pumps are equipped with two separate
mechanical seals.
The seals prevent the liquid being pumped from
entering the seal housing cavity from the pump
end, and at the same time prevents the oil in the
seal housing from leaking into the motor housing.
The upper pump seal is lubricated by oil in the seal
housing (see LUBRICATION at the end of this
manual). The lower seal is lubricated by the medi­
um being pumped.
There is no other lubrication required for these
pumps.
