    Pump Shaft Quality (PSQ)

    In the stainless and nickel industries, Pump Shaft Quality (PSQ) indicates turned, ground and polished shafting used in the rotating industries. The tight diametrical tolerance achieved through grinding decreases wear and gives a more constant product with controlled properties. Our inventory consists of diametrically oversized material in 20’ to 24’ random lengths, allowing Raaj Sagar to meet very specific customer requests for nonstandard PSQ requirements on an expedited basis.

    Raaj Sagar 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.
