The power steering pump (Power Steering Pump) is one of the key components in the power steering system. Its main function is to generate hydraulic oil flow through mechanical force to provide power to the steering system.

Due to the different viscosities and compositions of the transmission fluid, it may not provide the ideal lubrication required by the power steering system. This will cause increased friction inside the pump and pipes, and long-term use may accelerate wear and shorten the life of the pump.

In the current automotive market, hydraulic power steering systems (HPS) and electronic hydraulic power steering systems (EHPS) are still widely used, and both systems rely on power steering pumps.
