When it comes to manufacturing pump shafts, quality is essential. These critical components must be able to withstand high pressure, harsh environments, and heavy loads, all while maintaining their dimensional integrity and resisting corrosion. That’s where Pump Shaft Quality (PSQ) long bar comes in.

PSQ long bar are made of specialized alloys engineered specifically for use in the manufacturing of shafts used in corrosive environments. It is characterized by its exceptional strength, durability, and resistance to corrosion. To achieve these properties, the PSQ long bar is made using a specialized manufacturing process that involves precision straightening, centerless grinding, and polishing. This results in a bar with extremely tight tolerances and a smooth surface finish.

One of the primary advantages of PSQ long bar is its ability to resist stress corrosion cracking. This is a phenomenon that can occur in certain types of alloys when they are exposed to high levels of stress in corrosive environments. PSQ long bar is formulated to resist this type of corrosion, making it an ideal choice for pump shafts that will be used in harsh environments.

Another key advantage of PSQ long bar is its ability to maintain its dimensional stability over time. Because it is manufactured to such tight tolerances, there is very little variation in size or shape from one bar to another. This means that manufacturers can rely on the consistency of PSQ long bar when designing and manufacturing pump shafts.
