Abstract

The problems commonly encountered in a centrifugal pump are leakage, excessive noise, excessive heat, suction clog no-pumping, and damage of its components. Major reasons for the failure of a pump are excessive stress, reduction in strength of its component, variation in applied load, and poor design. Continuous working of the centrifugal pumps is essential in process industries such as paper mills, textile mills and refineries, for non-stop operation of the plants. In such cases reliable functioning of the pump is an absolute necessity. The major objective of this paper is the analysis of component life and frequency of occurrence of problems in a centrifugal pump. A survey was conducted among pump users to collect data on component life and occurrence of problems in pumps. Data collected through the survey were subsequently analyzed.
