China Excavator Repair Maintain Hydraulic Piston Pump Parts Sauer 90m75 | Tonkee®

The Sauer 90M75 is a variable displacement axial piston pump designed for demanding hydraulic applications, particularly in heavy machinery like excavators.

Its specifications are tailored to meet the high-pressure and high-flow requirements of such equipment. The pump is known for its robust construction, precision engineering, and reliability in challenging operating conditions.

One key specification of the Sauer 90M75 is its variable displacement capability. This means that the pump can adjust its displacement to control the flow of hydraulic fluid. This feature is crucial in excavators where the hydraulic system needs to adapt to varying loads and operational requirements. The pump's displacement range and adjustment mechanisms are designed to provide versatility and efficiency in different working conditions.

The hydraulic piston pump operates based on the axial piston principle. It consists of a cylinder block with pistons arranged in a radial pattern. As the pistons reciprocate, they generate hydraulic pressure, facilitating the movement of fluid through the hydraulic system. The Sauer 90M75 is engineered to deliver high efficiency in converting mechanical power to hydraulic power, minimizing energy losses and maximizing overall system performance.

Proper maintenance of the Sauer 90M75 hydraulic piston pump is vital to ensure its longevity and reliability.

Regular inspection of the pump's components, including the cylinder block, pistons, swash plate, and bearings, is essential. Any signs of wear, damage, or leakage should be addressed promptly to prevent further deterioration and potential system failures.

Routine fluid checks and replacements are critical to maintaining the pump's optimal performance. Hydraulic fluids should meet the specifications recommended by the pump manufacturer, and fluid levels should be regularly monitored to prevent cavitation and ensure proper lubrication. Contaminated or degraded hydraulic fluid can significantly impact the pump's efficiency and lead to premature wear.

In addition to preventive maintenance, it is essential to follow the manufacturer's guidelines for repairs. If the pump requires servicing or replacement of parts, using genuine Sauer 90M75 hydraulic piston pump parts is crucial. Genuine parts are designed to meet the pump's specifications and tolerances, ensuring compatibility and reliable performance.

Proper installation and alignment of the Sauer 90M75 hydraulic piston pump are equally important. Incorrect installation can lead to misalignment issues, increased wear, and reduced efficiency. Following the manufacturer's guidelines for installation and alignment procedures helps prevent these problems and ensures the pump operates within its intended parameters.
