4  Transportation, Storage and 

Lifting

Check and document any damages in the transport packages 

or dampeners. Contact the transportation company in case of 

damage. When new or unused dampeners are sitting idle for 

long periods, the following procedures should be complied 

with: 

1.  Prior to storage, thoroughly drain dampeners of any and 

all water. 

2.  Indoor storage is required. For unfavourable 

environment, cover the equipment with protective 

tarpaulin that will allow proper air circulation. 

3.  Protect the equipment from temperature and humidity 

extremes and exposure to excessive dust, moisture, 

vibration, sunlight, ozone and solvents.

4.  Cover the flange openings. 
5.  Do not store any objects on top of the rubber hoses. 
6.  Before operation clean the dampener.

When storing used dampeners, wash them with fresh water 

and follow the steps above. For storage periods greater than 

36 months, please contact Valmet Flow Control as the rubber 

parts need to be changed before use.

Lifting equipment must be used for dampeners weighing 

over 25kg.

Lift the dampeners securely from the cover hose (part 2). Use 

soft straps for lifting as shown in Figure 4. Lifting example.

Figure 4.  Lifting example.

Do not attach lifting equipment to the bore as it can damage 

the dampener. For Expulse™ dampener dimensions and 

weighs refer to 

Appendix A

.

5  Installation 

 WARNING!

High pressure injection hazard.

Do not use higher pressure than rated for the dampener. 

Higher pressures can cause serious damage to the 

equipment and harm to operating personnel.

Do not pressurise the pipeline before the dampener is 

properly installed.

Do not install the Flowrox Expulse™ dampener on the 

feed side of a pump. The dampener is not designed to 

work under vacuum may be damaged.

Do not twist or rotate the dampener with any tools if the 

other end is attached to a pipeline. The dampener can be 

damaged.

5.1  General

Flowrox Expulse™ inline pulsation dampeners are normally 

delivered fully assembled and ready for use. Only personnel 

with appropriate training are allowed to install the 

dampeners.

If the dampener is delivered disassembled it must 

be assembled in accordance with the manufacturer’s 

instructions. 

Flowrox Expulse™ dampeners include connections with 

threaded connectors.

Reserve enough space for safe installation and maintenance. 

See 

Appendix A

 for Expulse™ dampener dimensions.
