Hello Guys!

We are facing vibration problem in the piping system of our plant. The scenario is that the lean Amine pumps operate with a vibration of approx 6 mm/sec pk on DE and 3.8 mm/sec pk on NDE. The vibration gets transmitted through the piping into the standby pump which is not in operation. The vibration recorded on the standby pump is approximately 3.0 mm/sec pk. Do you have suggestion how to control this vibration?

Regards,

Imran Ahmed
