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