Gorman-Rupp Pumps SE1 1/2A3 115V 1P 1483930 and up - Manual (Page 10)

OM−06488 SE SERIES
PAGE B − 3 INSTALLATION
When installing or servicing the pump
or controls, follow all requirements for
the installation of wiring or electrical
equipment as outlined in the National
Electric Code. Follow all safety require-
ments. Failure to observe these require-
ments could result in injury or death to
personnel.
NOTE
Refer to the performance curve in Section E when
determining the most efficient piping installation.
The recommended maximum submergence
depth is 23 feet. Greater depths could result in
damage to the pump
Lifting
Use lifting equipment with a capacity of at least
five times the weight of the pump, including the
weight of the cable, if applicable, and any options
or customer-installed accessories. Discharge hose
or piping must be removed before attempting to lift
the pump.
Refer to Table B−2 for the approximate maximum
weight for each pump.
Do not attempt to lift the pump by the
motor power cable or the piping. Attach
proper lifting equipment or a rope to the
lifting device fitted to the pump.
Positioning the Pump
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.
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−2 for typical pump installations.
All liquid entering the pump must pass through a
strainer screen. Any spherical solids which pass
through the screen will pass through the pump.
