The Alfa Laval SRG 509 Solid Bowl Disc Stack Separator is a heavy-duty centrifugal separation system engineered for high-efficiency purification and clarification processes. Manufactured by Alfa Laval, this model is widely used in marine, edible oil, biodiesel, and industrial fluid processing applications.

This separator features a solid-wall bowl design, making it ideal for operations where manual sludge removal is acceptable and consistent separation performance is required. The advanced disc stack technology significantly increases the effective settling area, allowing faster and more efficient separation of liquids and solids.

The SRG 509 is equipped with a hermetic inlet and outlet system, ensuring contamination-free processing and minimal product loss. Its robust mechanical construction and precision-balanced rotating assembly allow smooth high-speed operation with reduced vibration.
