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.
Attach a rope or chain to the lifting handle in the top
of the motor cover. Do not lift the unit by the power
cables or the discharge piping. Do not attach lifting
equipment to the carry handle. Customer installed
equipment such as rigid discharge piping must be
removed before attempting to lift.
Do not attempt to lift the pump by the
power cables, carry handle or piping.
Attach proper lifting equipment to the
lifting eye fitted to the pump.
Positioning the Pump
This pump is designed to operate fully or partially
submerged; however, it should not be operated
dry for extended periods of time.
Extended dry operation will destroy the
seal assembly.
Secure and support the pump by the lifting eye fit-
ted on the pump. If the application involves a lot of
debris, protect the pump from excessive wear and
clogging by suspending it in a perforated barrel or
culvert pipe. If the bottom is heavily sludge-cov-
ered, rest the pump on support blocks or suspend
it from a raft or similar device near the surface of the
liquid. See Figure 2 for typical pump installations.
The pump is provided with a suction strainer to pre-
vent large solids from clogging the impeller. Any
spherical solids which pass through the strainer
will pass through the pump.
