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 to the lifting
device fitted to the pump. If chains or
cable are wrapped around the pump to
lift it, make certain they are positioned
so as not to damage the pump, and so
the load will be balanced.
Positioning the Pump
The pump is designed to operate fully or partially
submerged. It may also be operated in air for ex-
tended periods. The rotating parts are oil lubri-
cated, and the motor is cooled by a constant flow of
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-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. NOTE
Before actual operation, check the direction of im-
