buy E303 E304 Caterpillar Excavator Main Pump 208-1149 2081149 Pompa idraulica | PartsDic®_Excavator Idraulics, Motore diesel, SKS idraulico

The specific displacement value for the 208-1149 (2081149) hydraulic main pump is not directly given by the part numbers. For smaller excavators like the Caterpillar E303 and E304, which still require sufficient hydraulic power for functions such as arm movement, Funzionamento del secchio, and rotation, the displacement is likely to be in the range of 30 – 60 centimetri cubici per rivoluzione (cm³/rev). Tuttavia, the exact displacement should be obtained from Caterpillar's official product documentation.

Pressione operativa

Pressione nominale: La pressione nominale di questa pompa è in genere intorno 250 – 300 sbarra (25 – 30 MPA). This pressure rating enables the pump to effectively drive the hydraulic actuators in the E303 and E304 excavators, ensuring smooth operation of functions like digging, lifting light to moderate loads, e manovrare.

Pressione massima: La pressione massima che la pompa può resistere per brevi periodi è generalmente superiore alla pressione nominale, spesso raggiungendo fino a 350 sbarra (35 MPA) o più. This additional pressure capacity allows the pump to handle sudden high-load situations that may occur during the operation of the excavators, such as when working in slightly tougher soil conditions.
