Hydrohermetic Sealing for Flottweg Separators
As an option, Flottweg can offer hydrohermetic sealing of clarifier separators (for example, industrial disk stack centrifuges). Hydrohermetic sealing prevents the undesired uptake of oxygen into the product.
How Flottweg Hydrohermetics for Separators Works
Seal water is introduced through a solenoid valve into the seal water chamber of the rotating bowl, where it encounters the immersed sluice plate to form a water seal of the interior of the bowl from the surrounding atmosphere. This prevents oxygen from being introduced into the product, as well as preventing the product from releasing gases. Degased water is recommended for use as the seal water.
Excess seal water is guided over the overflow edge of the seal water chamber.
