Review of fault modes and failure diagnosis methods for magnetic-driving pump

Magnetic pumps transmit torque without leaks using magnetic induction, offering superior sealing over conventional pumps by replacing dynamic with static seals. They are vital for handling hazardous or valuable fluids, enhancing safety and efficiency while cutting maintenance costs. Despite their reliability, they face failure risks from temperature, lubrication, and contamination. This article reviews fault patterns, causes, and impacts in magnetic pumps and explores advanced sensor-based and intelligent diagnostic methods to predict and prevent failures, ensuring stable operation and reducing downtime. It provides a comprehensive overview of current fault diagnosis techniques and future research directions in the field.
