Regular Maintenance and Inspection

7004219
One of the most effective ways to prolong the life of hydraulic pumps is through regular maintenance and inspection. Establish a routine schedule that includes checking for leaks, loose connections, and signs of wear and tear. Pay attention to the condition of hydraulic fluid, as contamination can lead to pump failure. Regularly changing the oil and filters will help maintain the quality of hydraulic fluid.
Proper Fluid Quality
Hydraulic fluid quality is paramount in ensuring the longevity of Sauer Danfoss pumps. Use only high-quality fluids that meet the manufacturer’s specifications. Contaminated or incorrect fluids can lead to increased wear, overheating, and ultimately, pump failure. Implementing a filtration system can reduce the risk of contamination and keep the hydraulic fluid clean.
Correct Sizing and Selection
Selecting the correct pump size for your application is crucial for optimal performance and longevity. Oversized or undersized pumps can lead to inefficiencies and increased wear. Evaluate the operating conditions and choose a pump that matches the requirements of your specific application. Consulting with a knowledgeable supplier or distributor can help in making the right choice.
Operating Conditions
Be mindful of the operating conditions in which the hydraulic pump will work. Extreme temperatures, pressure fluctuations, and high fluid contamination levels can all negatively impact the pump’s lifespan. It is essential to keep the pump within its specified temperature and pressure ranges. Additionally, ensure that the hydraulic system is properly vented to reduce aeration and cavitation, which can cause significant damage over time.
