Have you tried using flinger discs instead of oil rings in pump bearing housings? I have observed that many pumps running at 3600 rpm with oil rings can experience darkening oil with brass powder contamination if the oil level is not precise. This contamination appears to be originating from the oil ring rather than the bearing cage. TriCo Manufacturing Corporation offers these flinger discs as an alternative solution. If anyone has experience or insights on using these discs, it could potentially alleviate contaminated oil issues in the field where oil mist is not an option. Your input is appreciated. Thank you, Tim.
Heinz Bloch offers valuable insights into addressing oil ring instability in centrifugal pumps, suggesting the use of flinger discs as a solution. While we have not personally tested this approach yet, we do encounter issues with greying oil on our 3600rpm overhung centrifugal pumps. It is important to note that there could be various factors contributing to this issue aside from the oil ring itself. Nevertheless, replacing a troublesome oil ring with a more dependable flinger disc appears to be a practical and logical choice.

Thank you for responding. Many issues have been identified, such as bent oil rings, dings in the shaft groove, and the oil level set too high, all of which are negatively impacting the performance of the oil rings. I believe that using a flinger disc can address these issues effectively. I will update with the results if I am able to replace the oil ring without encountering too many complications. Thank you once again.
Hey Tim, I appreciate your insights. I haven't personally used flinger discs, but I've heard from several colleagues that they can be a good alternative to oil rings. In fact, they apparently improve the distribution of oil around the bearing housing, reducing contamination and issues with darkening oil. However, they pointed out that the transition to flinger discs might require some adjustments and additional checking during the initial phase. Overall, it seems like exploring these as an option might be worth considering, especially in environments where oil mist isn't possible.
Hi Tim, great question! I've indeed used flinger discs with oil-lubricated bearings in the past. When implemented correctly, they can considerably reduce oil contamination and prolong the lifespan of the assembly. From my observation, the oil doesn't degrade as rapidly and contamination from metallic particles seems minimal. It's crucial, though, to ensure the disc is properly installed and maintained for optimal performance. In environments where oil mist isn't a viable option, this could indeed prove to be a beneficial alternative solution.
Hey Tim, excellent observation there! I have had similar experiences with brass powder contamination and it's a real nuisance. With my recent project, I gave flinger discs a try and they've shown considerable improvement in reducing this issue. The assembly process was relatively simple and it helped maintain cleaner oil. I'm also impressed with their durability and how they hold up even at high RPMs. I'd definitely recommend giving them a trial especially if oil misting isn’t an option. However, keep in mind that they may not be a 'one-size-fits-all' solution for every pump design, so it's important to assess their compatibility with your specific setup.
Hi Tim, I found your experience quite interesting. We did experiment with flinger discs in some older models and the oil contamination significantly reduced, though not completely eliminated. As I understand it, the flinger discs work by throwing off the excessive oil which efficiently regulates the oil level. Therefore, we're certainly considering increasing their usage. The only hindrance we've had is the initial cost difference. But given the long term potential savings, it seems worth considering. It’s crucial, however, to evaluate their efficacy under different operating conditions to ensure consistent performance, particularly in high-speed applications. Thanks for bringing this up!
Hi Tim, I haven’t personally used flinger discs yet, but I've heard some positive feedback from peers in the industry about them, especially in high-speed applications. It makes sense that they could help manage oil contamination better than traditional oil rings, especially if the oil level is a bit off. With the consistent RPMs and the risk of brass powder, it seems worth exploring. Have you considered running a side-by-side comparison in a controlled setup to really see the difference in oil quality over time? That could provide some solid data for the community. Thanks for bringing this up!
Hey Tim, I've seen similar issues with oil rings causing contamination and have been curious about the flinger discs too. In my experience, they do seem to help maintain oil clarity and reduce wear, especially in high RPM applications like yours. The design of the discs allows for more controlled oil flow, which can minimize that brass powder problem you've mentioned. I haven't done a direct comparison yet, but I'm definitely considering making the switch for my setups. It would be great to hear more from anyone who's already implemented them—such insights could save us a lot of hassle down the line!
