Main Cooling Seawater Pump (Centrifugal) · Pumps
The Thordon Bearing Condition Monitoring Wireless System (BCM-W) utilizes advanced wireless technology to monitor the health and performance of marine bearings in real-time. This system is marine-rated and compatible with seawater, freshwater, and oil environments. Certified through DNV-approval with the model number TAA00003MR, the BCM-W provides critical data that helps prevent common failures such as mechanical seal leakage after 8,000 to 12,000 operating hours, impeller erosion due to cavitation with insufficient net positive suction head (NPSH), and wear of the coupling after 15,000 to 20,000 hours. Regular maintenance practices include inspecting the mechanical seal every 8,000 to 12,000 hours, conducting annual coupling leakage checks, inspecting the coupling and impeller at docking, and performing quarterly vibration measurements. Spare parts such as mechanical seals and impellers should be kept on board, with a lead time of 2 to 6 weeks as specified by the manufacturer.
