INSTALLATION AND COMMISIONING
5.1
Unpacking
When unpacking carefully follow the instructions as given on the packaging or on the pulsation
dampener.
5.2
Inspection
Check that your delivery is correct and check it for any transport damage
5.3
Installation conditions
5.3.1 Ambient conditions
Make sure the ambient temperature, during normal operation of the pulsation dampener, does
not fall to below -20°C, and does not 65°C.
5.3.2 Set-up
When installing the pulsation dampener consider the following points:
•
The pulsation dampener will not be effective for variable pump speeds or variable dis
charge pressures.
•
Limit the presence of sharp bends. Make sure that the radius of the bent discharge line
is as large as possible. It is recommended to use Y-connections instead of T-connec
tions.
•
The pulsation dampener will be most effective if it is directly mounted onto the hose
pump. Minimise the distance between pump and pulsation dampener.
•
The pulsation dampener may be installed in either the horizontal or vertical position.
•
The pulsation dampener must be suitably supported.
If installed in potentially explosive atmospheres properly earth the pulsation dampener
and respect the instructions as mentioned in paragraph: “Use in Potentially Explosive
Environments (ATEX)”
•
Avoid, at all times, a pressure higher than the maximum operating pressure.
•
Avoid too heavy loads on the flanges. The maximum forces are given in the table below:
5.4
Lifting and moving the pulsation dampener
To lift, move and position the pulsation dampener, suitable hoisting belts must be used. The
best place to attach the hoisting belts is immediately behind both flanges of the pulsation
dampener. Keep in mind the pulsation dampener’s weight. For weights see also paragraph
“Weights table”.
WARNING
If the pulsation dampener is to be lifted, ensure that all safety regulations for lifting
movements are adhered to and that the lifting is carried out by qualified personnel
only.
