Without specific Komatsu product documentation, it's difficult to determine the exact displacement precisely. Cu toate acestea, for hydraulic gear fan pumps used in large excavators like the PC800-8, PC850-8, and PC1250, the displacement is an important parameter that affects the flow of hydraulic fluid to drive the fan motor. It could typically range from 50 to 200 centimetri cubi pe revoluție (cm³/rev), depending on the specific design and requirements of the pump for these heavy-duty machines.

These pumps are designed to operate at pressures suitable for powering the fan motors in the excavators' cooling systems while also potentially being part of the main hydraulic system. The maximum operating pressure is likely in the range of 100 bar (10 MPA) to 250 bar (25 MPA). This pressure range ensures that the pump can effectively drive the fan to maintain proper cooling of the engine and other components, as well as perform other hydraulic functions if applicable.
