buy Excavator Part K3V112S-1P5L-1PA9-3 Hydraulic Piston Pump EX1900-6 Fan Pump for Hitachi | PartsDic®_Excavator Idraulics, Motore diesel, SKS idraulico

Pressione nominale: La pressione nominale di questa pompa è in genere intorno 150 – 200 sbarra (15 – 20 MPA). Since it is a fan pump and not directly involved in heavy-duty hydraulic operations like digging or lifting, this pressure rating is sufficient to drive the fan with the necessary force for efficient cooling.

Pressione massima: La pressione massima che la pompa può resistere per brevi periodi è generalmente superiore alla pressione nominale, spesso raggiungendo fino a 250 sbarra (25 MPA) o più. This additional pressure capacity allows the pump to handle sudden surges in load, such as when the excavator is operating under extreme conditions and the cooling system requires increased fan speed.
