VSQ Bars

VSQ Bars

Our bars are crafted with precision from high quality stainless steel, oering exceptional durability and corrosion resistance. Rigorous quality checks ensure they meet industry standards, making them ideal for demanding pump manufacturing applications. Within the stainless and nickel sectors, Pump Shaft Quality (PSQ) refers to shafting that has undergone turning, grinding, and polishing processes for use in rotating industries. The precision in diametrical tolerance achieved through grinding reduces wear and ensures a consistently high-quality product with controlled properties.
