One of the most common issues with Sauer Danfoss pumps is contamination of hydraulic fluids. Particles, water, and other impurities can significantly affect pump performance, causing wear and potentially leading to failure. To prevent contamination, it is crucial to regularly check and change the hydraulic fluid according to the manufacturer’s specifications. Furthermore, employing high-quality filters and routinely monitoring system cleanliness can help keep the hydraulic fluid free from potential contaminants.

Overheating is another frequent problem that can dramatically decrease pump lifespan. High temperatures can lead to lubrication breakdown, component warping, and material fatigue. To avoid overheating, ensure that the system is designed to maintain proper operating temperatures. This may include using heat exchangers, maintaining sufficient fluid levels, and ensuring adequate ventilation around the pump.
Improper alignment and installation can also lead to excessive wear and damage. Misalignment can cause vibration, which puts additional stress on the pump components. To prevent this issue, it is essential to follow the installation guidelines provided by Sauer Danfoss carefully. Regularly check the alignment and make adjustments as necessary. Additionally, using vibration analysis tools can help identify misalignment early on, allowing for timely corrections.
Another factor that can impact pump longevity is the cycling frequency of the hydraulic system. Frequent starts and stops can lead to increased wear on pump parts. Strategies to reduce cycling frequency include evaluating the system design to ensure appropriate flow and pressure conditions and adopting control strategies that minimize abrupt changes in demand.
