Check Explanation/comment Checked
Check that the suction or discharge lines are not
forced into position.
Coupling and bearing wear will result if suction
or discharge lines are forced into position.
The code for Pressure Piping (A.S.A.B. 31.1) lists
many types of supports available for various
applications.
Check that fittings for absorbing expansion are
installed in the system when considerable
temperature changes are expected.
This helps to avoid strain on the pump.
Check that you have a foot valve of equal or greater
area than the pump suction piping when you use in
an open system with a suction lift.
Prevent clogging by using a strainer at the
suction inlet next to the foot valve. Make sure
that the strainer has an area three times that of
the suction pipe with a mesh hole diameter of
no less than 0.25 in. (0.64 cm).
Check that flexible piping is used on both the suction
and discharge sides of the pump when you use an
isolation base.
—
Check that a B&G Triple Duty
®
valve is installed in the
discharge line.
This valve serves as a check valve that protects
the pump from water hammer, and serves as an
isolation valve for servicing and for throttling.
Check that the pipeline has isolation valves around
the pump and has a drain valve in the suction pipe.

4.2 Typical pump installation
Various installation arrangements can be used as described below.
Series e-80SC pumps can be installed directly in the piping with pipe hangers adequate
to carry the loads from the pump and piping.
Figure 4
In many installations, the piping is installed near the ceiling with the pump located close
to the floor for ease of maintenance. Pumps with up to 4 inch nozzles and up to 286
NEMA (180 IEC) frame motors can be installed in this configuration with pipe hangers
adequate to carry the loads from the pump, piping and piping accessories. Larger pumps
can be installed in this configuration but require either the optional B&G Flange Supports
or a floor support under the discharge elbow and an adjustable support leg under the
B&G Suction Diffusor Plus.
