Typical Pump Installation - Bell and Gossett e-80SC Series Instruction Manual

4 Installation
Check
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 suction piping when you use in
an open system with a suction lift.
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
discharge line.
Check that the pipeline has isolation valves around
the pump and has a drain valve in the suction pipe.

Explanation/comment
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.
This helps to avoid strain on the pump.
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).

valve is installed in the 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.

Series e-80SC pumps can be installed directly in the
piping with pipe hangers adequate to carry the loads
from the pump and piping. See
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 Diffuser Plus. See
