At what RPM does the Delaval purifier typically operate?

The Delaval purifier typically operates at a speed of 1800 RPM, which is optimal for its design and functionality. This high RPM allows the purifier to effectively separate different phases of liquid based on their density, such as water and oil. The centrifugal force generated at this speed enhances the separation process, making it more efficient in removing impurities from the liquid. Operating at lower speeds may not provide sufficient force for effective separation, while extremely high speeds could lead to mechanical stress and operational issues. Thus, 1800 RPM strikes a balance that ensures both efficiency in separation and the longevity of the equipment.
