Understand the Temperature Range

83010830
Before making a selection, it’s important to understand the specific temperature range of your application. High-temperature hydraulic systems can exceed standard operational limits, typically in the range of 50°C to over 120°C. Knowing the maximum temperature your system will encounter allows you to choose a pump that is rated for those conditions.
Consider Fluid Compatibility
At elevated temperatures, the type of hydraulic fluid used becomes increasingly significant. Ensure that the hydraulic fluid is compatible with the pump’s materials and seals. Danfoss hydraulic pumps are often designed to work with a variety of fluids, but confirming compatibility with high-temperature fluids is crucial to prevent degradation of components.
Evaluate Pump Design
Danfoss offers various pump designs such as gear pumps, piston pumps, and vane pumps. Each design has its advantages and limitations. For high-temperature applications, piston pumps may be preferred due to their ability to maintain performance and efficiency at elevated temperatures. Assess the specific application needs, such as pressure requirements, flow rates, and operational efficiency, to determine which design suits your conditions best.
Check Temperature Ratings
Each Danfoss hydraulic pump model comes with specific temperature ratings and performance curves. Review these specifications to ensure the pump can handle your application’s high temperatures. Selecting a pump rated for higher temperatures than your maximum expected temperature can provide an added safety margin for unforeseen operational conditions.
