Check Explanation/comment Checked
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.
This helps to avoid strain on the pump.
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 properly sized suction strainer
conforming to NSF/ANSI Standard 50 is installed in
the suction line.
Prevents clogging. Make sure 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 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-580 pumps can be installed directly in the piping with pipe hangers adequate to
carry the loads from the pump and piping.
Figure 2
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 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 suction piping.
Figure 3
Pumps can be installed in the piping with floor mounted saddles adequate to carry the
loads from the pump and piping.
