Just another confirmation needed that the diagnosis is correct. I've been analysing this thermal fluid pump for a while now, its had high readings before but now they started increasing again. I suspected internal mechanical looseness within the pump but i'm only basing it on the DE H reading as its the highest (a number of synchronous running speed harmonics are dominating the spectra data). the time-wave form shows signs of impacting so that would partially confirm my suspicions, however we put a new motor on two months ago, had it laser aligned and it ran great. low readings. the readings this month have started to pick up and i'm wondering if the vibrations from the pump would create vibrations through and into the motor too? I am fairly new to this so this might be a basic error. I've attached pictures of all the spectras to show you guys what is happening.
Motor is a Brook crompton 55kw 2960rpm.
Centrifugal Pump KSB Horizontal volute casing pump, single-stage pump size 100-250
