Gorman-Rupp Pumps SE2C3 115V 1P 1483930 and up - Manual (Page 10)

OM−06492 SE SERIES
PAGE B − 3 INSTALLATION
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.
All liquid entering the pump must pass through a
strainer screen. Any spherical solids which pass
through the screen will pass through the pump.

Figure B-1. Typical Pump Installations
Piping
No suction piping is required in a standard installa-
tion. This pump is provided with a suction strainer
to prevent large solids from clogging the impeller.
To determine the size of the discharge connection,
see Table B-1. Either hose or rigid pipe may be
used. To facilitate mobility and maintenance, it is
recommended that the discharge line be fitted with
a quick disconnect fitting near the pump. The dis-
charge line must be independently supported to
avoid strain and vibration on the pump.
Either hose or rigid pipe may be used to make dis-
charge connections. For maximum pumping ca-
pacity, keep the line as short and straight as pos-
sible. Elbows and fittings used in discharge lines
increase friction loss, minimize their use.
It is recommended that a check valve or throttling
valve be installed in the discharge line to control si-
phoning or back flow when the pump is shut off.
ELECTRICAL CONNECTIONS
Install and operate this pump in accor-
dance with the National Electrical Code
and all local codes. Have a qualified
electrician perform all checks and con-
nections in this section.
Never attempt to alter the length of the
pump motor cable or to repair it with a
splice. The power cable and pump mo-
tor must be kept completely waterproof.
