Pump Shaft Quality (PSQ) Bar
Ram Alloys is a leading provider of stainless steel & nickel alloy pump shaft quality (PSQ) bar as well as custom bar that have been specially processed for high performance. Pump shaft quality indicates turned, ground, and polished shafting used in rotating applications. The treatment of these PSQ bar leads to a tighter diameter tolerance by reducing the effects of wear while maintaining optimal functionality. Straightening treatments also enhance the performance of pump shaft quality bars, ensuring they create minimal vibration throughout the entire shaft length. The result is a more efficient, reliable, and high-performing pumping system.
