Amine pumps are the most critical components in Iran's South Pars Gas Complex. Their importance become clear when interruption in their operation and maintenance create reducing or stopping of production. So monitoring their condition is very important. In this study, an experimental method is presented for condition monitoring of an amine pump. In addition, the amine pump is modeled in ANSYS finite element software. The first three natural frequencies and the first three natural modes are presented in modal analysis and due to the practical excitation frequency of an amine pump is used 100 hertz, resonance is occurred at the first natural frequency. Finally in order to reduce of vibrations, grouting process and strengthening of foundations of the amine pump is performed. For strengthening of foundations of the amine pump, two Ishaped beams at the beginning and ending and four latchkeys around basing are installed. Experimental data results show that the value of the vibrations in the junction box of amine pump is set in the allowed range according to ISO standard.
