Low-flow, high-head pumping requirements in refining and petrochemical plants make up less than 2% of the total pump population. This minor percentage is creating significant reliability concerns, which result in low mean-time between failures (MTBF), as well as high maintenance costs.

Case study: Improve vacuum tower operation with VFD addition

The bottom pump in crude vacuum units is an area of concern for almost all petroleum oil refineries. The harsh operating parameters in which these pumps operate, including high product temperature and significant vacuum suction pressure, have resulted in frequent vacuum tower upsets and low mean time between failures (MTBF) for vacuum bottom pumps.
