4.4.1 General information
Before connection, remove the pump suction and delivery port protection
caps.
A pump is generally part of a piping system that can include a number of components such as valves,
fittings, filters, expansion joints, instruments, etc. The piping layout and the position of these components
have an important influence on the operation and service life of a pump.
The pump must never be used as a support for the components connected to
it.
The thermal expansion of pipes must be compensated for using appropriate expansion compensators. The
pump-piping connection flanges must be centred and aligned before tightening the related bolts. Do
not, under any circumstances, attempt to pull or straighten the pipes by tightening the bolts of the flanges
or threaded fittings.
The suction and delivery lines and the installed valves or filters must be supported and anchored next to
but not on the pump so that no strain is transmitted to the body of the pump.
The forces and moments transmitted to the pump by the piping system must
not exceed the allowable forces and moments (see relevant section in the
chapter "Technical Data"
).
The piping must remain clean and free of debris (welding slag, small chips, etc.).
Remove the temporary filters specially provided after commissioning/testing the plant.
The liquid flow should be as straight as possible.
To the extent possible, elbows, tight bends, or radical reductions in diameters should be avoided as they
may cause head loss s in the plant.
If you need to reduce the diameter you should use appropriate eccentric reducers on the suction flange
(and concentric reducers on the delivery flange) at size changes, placed at a minimum distance from
pump ports equal to ten (10) times the diameter of the pipe.
