dc.description.abstractAll centrifugal sealless pumps, both canned motor and magnetic drive, should be monitored to determine mechanical condition. In sealless pumps, the pumped fluid is used as the cooling and lubricating medium for the pump bearings. If intermittent monitoring is used, then the chance of detecting pump damage caused by process changes is very small. Vibration monitoring techniques as applied to sealed pumps has been unreliable for detecting problems with sealless pumps. The effectiveness of conventional monitoring techniques is limited by the time interval between measurements, the relative isolation of the inner pump rotor from the outer measuring location, and by the pump fluid. Other factors such as fluid effects and process noises can make interpretation difficult. This paper presents the synergistic combination of two relatively new methods of sealless pump monitoring. These methods considerably enhance the range and magnitude of the mechanical problems that can be identified on this type of pump. One of the goals of predictive maintenance is the reduction of maintenance costs by use of condition monitoring. Identification of off-design operation conditions or mechanical damage at an early stage enables the equipment owner to correct the conditions before damage occurs, or to optimally schedule repairs. Continuous monitoring of sealless pumps, can reduce equipment maintenance costs and facilitate root cause analysis of mechanical failures and operational problems. This cost reduction is accomplished by the use of the monitoring system to immediately identify conditions that can lead to failure.en
