TFL bearings help leading centrifugal pump manufacturer save $120,000 a year
centrifugal pumps
An internationally renowned manufacturer of centrifugal pumps (hereinafter referred to as “the customer”), the products are widely used in petrochemical, municipal water supply, industrial circulation systems, and other fields. Its high-end centrifugal pumps have been facing the problem of insufficient bearing reliability for a long time; especially under high temperature, high speed, and heavy load conditions, the bearings are susceptible to early fatigue, lubrication failure, and sealing performance degradation, which leads to frequent equipment downtime and maintenance, and the customer’s operation and maintenance costs remain high.
Key Facts
- Tough working conditions: Centrifugal pumps can operate at speeds of up to 3000-6000 RPM, with bearings subjected to radial and axial composite loads, and medium temperatures often exceeding 80℃.
- Long-term stable operation requirements: the customer requires the equipment to run continuously for not less than 8000 hours, but the average life of the original bearings is only about 5000 hours.
- Maintenance cost pressure: Frequent replacement of bearings leads to an increase in labor costs, and unplanned downtime causes economic losses to the customer's production line.
- Read the latest reviews and success reports about our products, services, and customer support and see what people are saying about TFL.
The TFL Solution
- Optimised bearing design and selection: The combination of TFL high-precision cylindrical roller bearings (N10 series) and angular contact ball bearings increases radial load carrying capacity and balances axial thrust.
- Innovative sealing and lubrication technology: Integrated TFL's patented polymer seal creates a superb dust and waterproof rating and prevents failure due to grease contamination. Recommended High-temperature synthetic grease, adapted to the internal groove design of TFL bearings, ensures long-lasting lubrication and reduces replenishment frequency.
- Full life cycle service support: TFL engineers participate in the customer's equipment modification, provide guidance on bearing installation and commissioning, and offer a vibration monitoring program. Based on big data analysis to predict the remaining life of the bearings and formulate a preventive maintenance plan.
