Predictive Maintenance for Solvent Pump Reliability

This case study outlines the implementation of predictive maintenance strategies by AVT Reliability Ltd to enhance the reliability of a solvent supply pump in a pharmaceutical manufacturing environment. The document details the challenges faced due to potential equipment failure in an ATEX-classified area, where any disruption could lead to significant operational downtime and compliance issues. During a routine condition monitoring visit in January 2025, AVT's engineer identified concerning vibration patterns indicating a bearing defect. Following this diagnosis, the site maintenance team promptly replaced the motor bearings and conducted a thorough inspection. The proactive maintenance approach allowed for repairs to be scheduled during non-disruptive periods, thereby minimizing operational impact. The case study emphasizes the importance of early detection of mechanical issues through data-led maintenance practices, particularly in high-risk environments, ensuring continued operational efficiency and safety.
