Conjunto de bomba de pistón hidráulico Dan Foss 872G 83041431 AT457670 para excavadora John Deere 872G | PartsDic®_Excavator Hydraulics, Motor diesel, SKS hidráulico

Without specific product documentation from Dan Foss or John Deere, it's difficult to determine the exact displacement value. Sin embargo, for hydraulic piston pumps used in excavators like the John Deere 872G, the displacement is a crucial parameter. Normalmente podría oscilar entre 100 a 300 centímetros cúbicos por revolución (cm³/rev). A higher displacement enables the pump to deliver more hydraulic fluid per revolution, que es esencial para alimentar funciones como la elevación de la pluma, extensión del brazo, y funcionamiento del cucharón en la excavadora.

Presión de funcionamiento

These pumps are designed to operate at high pressures to meet the demanding requirements of excavator operations. The maximum operating pressure for the Dan Foss 872G hydraulic piston pump assembly (with model numbers 83041431 and AT457670) in the context of the John Deere 872G excavator is likely to be in the range of 250 bar (25 MPA) a 400 bar (40 MPA). This high pressure is necessary to drive the large hydraulic cylinders and motors that perform the heavy-duty tasks of the excavator.
