Rated Speed: The rated speed of the pumps is generally in the range of 1000 - 2000 rpm. Operating within this speed range ensures efficient operation and stable performance of the pumps, while minimizing wear and tear on their internal components such as pistons, valves, and seals.
Maximum Speed: The maximum allowable speed is usually around 2500 rpm. Continuous operation at the maximum speed may lead to increased wear and a reduced lifespan of the pumps. Thus, it is advisable to operate the pumps within the rated speed range for long-term reliability.
Pump Type
These are likely axial piston pumps or gear pumps, depending on the specific design by Sauer Danfoss for the John Deere 872G grader. Axial piston pumps offer high efficiency and the ability to handle relatively high pressures, while gear pumps are known for their simplicity and reliability. Without specific information from Sauer Danfoss, it's difficult to determine the exact type for these part numbers.
