How does the frame base connect to the ground? Are there four mount points that are fixed to ground? I suggest a beam model of the frame base, pipe supports and pipe be made. The pump unit can be represented as a rigid body whose mass matches that of the pump. A Modal analysis will show the free vibrations of that structure. You should add a Distributed Mass on the pipe elements to represent the weight of the liquid in the pipe.
