INSTALLATION
mergence depth is 65 feet.
Lifting
Pump unit weights will vary depending on the
mounting and drive provided. 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
equipment such as suction and discharge hoses
or piping before attempting to lift existing, installed
units.
Refer to Table B-2 for the approximate maximum
weight for each pump.
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.
Use
Only Genuine Gorman-Rupp
re
placement parts. Failure to do so may cre
ate a hazard and damage the pump or di
minish optimal pump performance. Any
such hazard, damage or diminished per
formance is not covered by the warranty.
NOTE
When appropriate recycling facilities are available,
the user should recycle components and fluids
when doing any routine maintenance / repairs and
also at the end of the pump’s useful life. All other
components and fluids shall be disposed of ac
cording to all applicable codes and regulations.
Positioning the Pump
NOTE
Before installing and operating the pump, check
the direction of impeller rotation to ensure that the
pump is properly wired at the control box. See
IM
PELLER ROTATION
, Section C.
The pump is designed to operate fully or partially
submerged. The rotating parts are oil lubricated,
and the motor is cooled by a constant flow of liquid
or air discharged through internal passages.
As a safeguard against rupture or explosion due to
heat, models equipped with oil‐lubricated motors
are fitted with a pressure relief valve which will open
if vapor pressure within the pump motor reaches a
critical point.
The pump will operate if positioned on its side, but
this is not recommended because the motor
torque could cause the pump to roll during opera
tion.
The pump should be independently secured and
supported by the lifting device fitted on the pump.
If the application involves a lot of debris, protect the
pump from excessive wear and clogging by sus
pending it in a perforated barrel or culvert pipe. If
the bottom is heavily sludge‐covered, rest the
pump on support blocks or suspend it from a raft
or similar device near the surface of the liquid. See
Figure B-1 for typical pump installations.
