Leading domestic high HLA4FO500 large displacement finale to a plunger pump

High performance, high reliability of the hydraulic piston pump is the core parts, engineering machinery hydraulic system is also a weak link in the field of construction machinery in China. Relative to other hydraulic components, the reliability of the plunger pump is more demanding, research and development is difficult. And constant force hydraulic r&d team adhering to the "China hydraulic pilot", adhere to independent research and development innovation, and always adhere to the r&d and production of plunger pump and motor work, and constantly breakthroughs in the field of hydraulic piston pump.

HLA4FO500 series of high-end hydraulic pump is a representative product of constant force hydraulic, rave reviews in the market.
