For safety and correct product usage, read the manual before this product is used.
Lifting option 1: Sling around the motor bracket.

3 Unit installation

WARNING:
• The heating of water and other fluids causes volu‐
metric expansion. The associated forces can cause
the failure of system components and the release of
high temperature fluids. In order to prevent this, in‐
stall properly sized and located compression tanks
and pressure-relief valves. Failure to follow these in‐
structions can result in serious personal injury or
death, or property damage.
• To avoid serious personal injury and property dam‐
age. Make sure that the flange bolts are adequately
torqued.
NOTICE:
Never force piping to make a connection with a pump.
Check:
• Check that the pump is not supported by placing hangers or floor supports on
the motor.
• Check that a section of straight pipe, with a length that is five times its diame‐
ter, is installed between the suction side of the pump and the first elbow, or that
a B&G Suction Diffuser is installed.
• Check that the suction and discharge pipes are supported independently by
use of pipe hangers near the pump.
• Check that there is a strong, rigid support for the suction and discharge lines.
• For pumps with flanges, check that the bolt holes in the pump flanges match
the bolt holes in the pipe flanges.
• Check that the suction or discharge lines are not forced into position.
• Check that fittings for absorbing expansion are installed in the system when
considerable temperature changes are expected.
• Check that you have a foot valve of equal or greater area than the pump suc‐
tion piping when you use in an open system with a suction lift.
• Check that a B&G Triple Duty ®
• Check that the pipeline has isolation valves around the pump and has a drain
valve in the suction pipe.
• Use PTFE tape sealer or a high-quality thread sealant when you install the suc‐
tion and discharge connections to a threaded pump housing.
• On an open system, check that the end of the suction pipe is at least 3 ft. below
the surface of the water in the suction well.
• Check that new flange gaskets are installed between the flanges of the pump
body end suction and discharge pipes. Make sure that these gaskets are clean
and grease-free.

Lifting option 2: Sling around pump flanges and use motor eyelets as guides to
maintain balance while lifting.
Ensure at least 8 inches (203 mm) of space is available above the motor, excluding
any other space required for lifting equipment, to permit removal of the pump rotat‐
ing assembly and sufficient airflow for motor cooling.
Min. 8 in. (203 mm)
Minimum recommended clearance above motor.
Recommended e-80X unit installation using pipe hangers.
Recommended e-80X unit installation using pipe stands.
The e-80X is compatible with all standard e-80 installation arrangements up to 256
frame. Two common installations are shown to the left. e-80X pumps may be in‐
stalled directly in-line with the piping using adequately sized pipe hangers or floor
mounted saddles to carry to the loads from the pump and piping.
Consult the standard e-80 IOM for a full list of installation arrangements.
