Abstract
Case StudiesChronic high vibration issue was being observed on a critical condensate pump. Although this motor driven pump is a standby unit, however, in case the running pump has a breakdown and the motor pump is unavailable, the Ammonia Plant will trip. This is a horizontal overhung, centerline mounted, single stage pump. The pump was relocated to current site in 1992 and the problem of high vibration was observed after ~10 years of operation. The issue was observed around the timeframe when locally manufactured spares were used since OEM had discontinued offering its spares. The pump was overhauled 03 times in past 10 years, but the high vibration issue remained as such
