Sauer Dan Foss 90R Series 42 55 75 100 130 180 250 Hydraulic Axial Piston Pumps | PartsDic® _Excavator Hydráulica, Motor diesel, SKS hidráulico

Presión nominal: The 90R series pumps typically have a rated pressure in the range of 350 bar (35 MPA) a 400 bar (40 MPA). This allows them to handle high – pressure hydraulic systems commonly found in industrial and mobile applications.

Máxima presión: The maximum pressure that the pumps can withstand for short periods is usually higher than the rated pressure, alcanzando 450 bar (45 MPA) o más, depending on the specific model and application requirements.

Caudal: The flow rate of the pumps is directly proportional to their displacement and rotational speed. At a given speed, the larger the displacement, the higher the flow rate. Por ejemplo, at a speed of 1500 rpm:

90R42: Flow rate = 42 cm³/vuelta × 1500 rpm = 63000 cm³/min = 63 L/min.

90R250: Flow rate = 250 cm³/vuelta × 1500 rpm = 375000 cm³/min = 375 L/min.
