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.
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.
