The canned motor pump has a unique design where the motor rotor and pump impeller are mounted on the same shaft, requiring careful balancing of axial and radial forces to ensure reliable operation. The use of a canned motor pump with a floating impeller system helps to balance the axial forces of the impeller, this balance ensures that the impeller is not subjected to excessive axial forces which can lead to premature wear or failure. The purpose of this study is to investigate the axial force on the canned motor pump when overheating occurs due to an operational fault in the distillation column. Investigation of the pump flow rate over 15 days showed a significant reduction in flow rate from 45,000 to 29,000 kg/h, while investigation of the pump amperage showed that the maximum amperage condition was around 54 to 60 amperes.
